xiii Introduction About the documentation This manual introduces the concepts and issues associated with printing to the Fiery 3850C™. It outlines key workflow scenarios, provides information on calibration and color profiles, and contains application notes that explain how to print to the Fiery 3850C from popular Microsoft Windows and Apple Mac OS applications. This manual is part of a set of documentation that includes manuals for users and system administrators.
xiv Introduction Color terms and concepts such as “RGB data,” “color space,” “spot color,” “gamut,” and “source profile” are used throughout this manual. If you are new to desktop color, or if any terms are unfamiliar, read Appendixes A and B or check the glossary.
xv Key features of ColorWise For consistent color make sure the Fiery 3850C is calibrated on a regular basis. ColorWise Pro Tools include a simple-to-use calibrator, which allows you to calibrate using a densitometer (see Chapter 3). You can modify printing results using ColorWise features.
1 1-1 Chapter 1: Fiery 3850C Color Management Managing color on the Fiery 3850C The first part of this chapter describes the options available from the ColorWise color management system and explains how to customize the color settings for your particular needs. It provides descriptions of the preset ColorWise default settings and covers additional options for users who need to customize ColorWise.
1 1-2 Fiery 3850C Color Management RGB Source Profile is the only color option that applies strictly to RGB color data. The other options that affect RGB color also affect the more rarely used Lab, XYZ, and other calibrated color spaces. N OTE : For users who are familiar with PostScript 3.0 color, RGB Source Profile affects all CIEBasedABC color spaces (if the source space is RGB).
1 1-3 Managing color on the Fiery 3850C Fiery 3850C color print option CMYK Simulation Profile SWOP-Coated/DIC/Euroscale/Simulation 1–10/None (Default set at Setup or in ColorWise Pro Tools) Output Profile Default output profile/Output 1–10 (Default set at Setup or in ColorWise Pro Tools) Pure Black Text/Graphics On/Off (Default set at Setup) Black Overprint On/Off (Default set at Setup) Spot Color Matching On/Off (Default set at Setup or with ColorWise Pro Tools) What it does Adjusts CMYK color da
1 1-4 Fiery 3850C Color Management Rendering styles The Rendering Style option specifies a CRD for color conversions. You can modify the Rendering Style option to control the appearance of images, such as prints from office applications or RGB photographs from Photoshop. The Fiery 3850C lets you select from the four rendering styles currently found in industry standard ICC profiles.
1 1-5 Managing color on the Fiery 3850C RGB Source Profile The RGB Source Profile setting allows you to define the characteristics of the RGB data in your document so the appropriate color conversion can occur on the Fiery 3850C. Commonly used monitor color spaces are available from the driver and from the ColorWise Pro Tools Profile Manager. For special needs, you can use ColorWise Pro Tools to download custom monitor or scanner profiles.
1 1-6 Fiery 3850C Color Management With RGB Source set to None, PostScript RGB data that contains a source color space definition is converted using the CRD specified by the Rendering Style option (see page 1-4). Non-PostScript RGB data and PostScript RGB data that does not contain a source color space definition is converted using a general undercolor removal conversion method. CMYK Simulation Profile The CMYK Simulation Profile print option allows you to print press proofs or simulations.
1 1-7 Managing color on the Fiery 3850C Changing the output profile only does not affect its associated calibration target (since the target is based on a printer model). You can edit D-Max values of the calibration target separately (see page 4-6). You can use the ColorWise Pro Tools Profile Manager to download your own output profile to the Fiery 3850C (see page 4-5). Downloaded output profiles are at first associated with the calibration target tied to the default output profile.
1 1-8 Fiery 3850C Color Management N OTE : The Pure Black Text/Graphics option can be used only when printing composites, not when printing separations. Pure Black Text/Graphics Input black color On Off RGB With the default profile, prints a rich black using all toners. CMYK Prints only with black toner, because CMYK simulations preserve the black channel. The actual amount of toner used depends on the current simulation and the calibration state of the printer.
1 1-9 Managing color on the Fiery 3850C One example of how you might use this setting is with a page that contains some black text on a light blue background. The background blue color is CMYK = 40%, 30%, 0%, 0% and the black text is CMYK = 0%, 0%, 0%, 100%. • With Black Overprint On, the final text portions of the page are overprinted, or combined with the underlying colors. This results in CMYK = 40%, 30%, 0%, 100% for the color used for the text.
1 1-10 Fiery 3850C Color Management Spot Color Matching and the PANTONE Coated Color Reference The PANTONE Coated Color Reference (described on page 5-6) prints differently depending on the Spot Color Matching setting. • On—The Fiery 3850C uses a built-in table to generate the best matches of the PANTONE colors that your printer can produce. The PANTONE number is printed below each swatch.
1 1-11 Printer drivers and print options Printer drivers and print options This section describes the role of the printer driver and explains how to use Windows and Mac OS PostScript printer drivers for Fiery 3850C printing. PCL printer drivers are also available, but they support only a few of the color features described in this manual.

2 2-1 Chapter 2: Simple and Advanced Workflows Workflow concepts This chapter discusses color management workflows used in short-run color printing, as well as color proofing on the Fiery 3850C. It also gives examples of color management in specific desktop applications and discusses the interaction between those applications and ColorWise color management.
2 2-2 Simple and Advanced Workflows RGB, CMYK, and PANTONE colors Colors can be defined in several different color models, the most common being RGB, CMYK, and the PANTONE color matching system. Each model requires a different color conversion at the Fiery 3850C. Color conversion workflows for CMYK and PANTONE colors are explained below. • CMYK colors are device-dependent.
2 2-3 Simple workflows Finally, by sending RGB files instead of larger CMYK files from applications to the Fiery 3850C, network traffic is minimized and jobs generally print faster. ColorWise uses ICC profiles to convert colors to the printer gamut or simulate other devices, such as an offset printing press. ColorWise manages color conversions for all users printing to the Fiery 3850C from Windows and Mac OS computers.
2 2-4 Simple and Advanced Workflows If printed colors are your priority, choose colors from printed samples. By using these sample colors, your printed output will remain consistent regardless of how the colors appear on different monitors. Print the palette of available colors from business applications and then select colors from the printed samples. Fiery 3850C Color reference files are included on the User Software CD (see page 5-2).
2 2-5 Simple workflows While this workflow lends some control over the color quality produced by the printer, you should consider additional ColorWise color management, as described in the next section.
2 2-6 Simple and Advanced Workflows The recommended values for CMYK Simulation are SWOP in the US, Euroscale in Europe, and DIC in Japan—choices that respect the color standard for each region. If colors have been selected specifically for your calibrated printer, set CMYK Simulation to None. See the table on page 1-2 for a list and descriptions of ColorWise print options that affect CMYK, RGB, PANTONE, and other colors.
2 2-7 Advanced workflows Save your files using color-safe settings You can take several additional steps to ensure color accuracy. • When saving EPS files, do not include PostScript Color Management information. This minimizes the risk conflicting data and multiple color conversions.
2 2-8 Simple and Advanced Workflows on the Fiery 3850C using a CRD rather than the application. Use the settings illustrated in this workflow for printing photographs and artwork. This document could be created as follows: • Create an RGB image in Photoshop. • Print the file directly to the Fiery 3850C. See Chapter 7 for recommended print settings from Photoshop. • Use ColorWise to convert the RGB image to printer CMYK, or the full copier gamut.
2 2-9 Advanced workflows Photoshop RGB with Illustrator and QuarkXPress CMYK and PANTONE colors This workflow involves short-run printing of a complex page layout with images saved in Photoshop, illustrations created in Illustrator, and PANTONE spot colors. A Photoshop image is saved in an RGB color space using the EPS file format. Illustrator artwork contains objects defined as CMYK and as PANTONE spot colors selected from printed output, and they are saved using the Illustrator EPS file format.
2 2-10 Simple and Advanced Workflows The ColorWise settings used in this example are: • RGB Source Profile set to EFIRGB or another RGB source definition • Rendering Style set to Photographic • CMYK Simulation set to None • Spot Color Matching set to On The diagram below indicates the steps for this particular workflow in black.
2 2-11 Advanced workflows Photoshop RGB with Illustrator CMYK and PANTONE and PowerPoint RGB This workflow involves short-run printing of a complex presentation document with images saved in Photoshop, illustrations created in Illustrator, and PANTONE spot colors. All elements are imported into PowerPoint for output. This document could be created as follows: • Create an RGB image in Photoshop and save it as Photoshop EPS.
2 2-12 Simple and Advanced Workflows The ColorWise settings used in this example are: • RGB Source Profile set to EFIRGB or another RGB source definition • Rendering Style set to Presentation • CMYK Simulation set to None • Spot Color Matching set to On The diagram below indicates the steps for this particular workflow in black.
2 2-13 Advanced workflows Color proofing examples The following examples illustrate methods for simulating the output from another printing system, such as an offset press. Each of the proofing examples uses an ICC profile to describe the destination color space. While some examples use simulation profiles built into the Fiery 3850C, others use ColorWise Pro Tools (see Chapter 4) to download custom ICC output profiles to the Fiery 3850C for use as simulation profiles. Photoshop 5.
2 2-14 Simple and Advanced Workflows The ColorWise settings used in this example are: • CMYK Simulation Profile set to the desired press standard or to the corresponding custom simulation (Simulation 1-10) if you downloaded your profile with ColorWise Pro Tools The diagram below indicates the steps for this particular workflow in black. Photoshop RGB-to-CMYK workflow using ICC profile Photoshop 5.
2 2-15 Advanced workflows Photoshop 5.x Built-in RGB-to-CMYK workflow This workflow is useful for prepress environments that have not integrated ICC color management and do not have profiles for the presses they use. In this example, an image is converted from RGB to CMYK using the Photoshop 5.x/6.0 Built-in color conversion features in the CMYK Setup option. (For more information on CMYK Setup, see your Photoshop 5.x documentation.

3 3-1 Chapter 3: Color Calibration Introduction Calibrating the Fiery 3850C ensures consistent, reliable color output. You can calibrate the Fiery 3850C with ColorWise Pro Tools using any of these instruments: • X-Rite DTP41 automatic scanning spectrophotometer (page 3-7) • X-Rite DTP32 automatic scanning densitometer (page 3-25) • EFI ED-100 Densitometer (page 3-25) Each of these instruments must be purchased separately.
3 3-2 Color Calibration Once you have calibrated the Fiery 3850C with ColorWise Pro Tools or with VisualCal, a calibration set is stored on the Fiery 3850C. This calibration set is used when it is associated with an output profile. Every output profile has an associated calibration set. If you have not specified one, the calibration set associated with the default output profile is used.
3 3-3 Understanding calibration How calibration works Success in obtaining satisfactory print quality from a color server, such as a Fiery 3850C, connected to a printer depends on many factors. Among the most important are establishing and maintaining optimal toner densities. Density is a measure of the light absorbed by a surface. By carefully regulating toner densities, you can obtain consistent printed color.
3 3-4 Color Calibration Output profiles and calibration sets Output profiles and calibration sets define desired calibration results. One or more output profiles and one or more calibration sets are provided with the Fiery 3850C. When you calibrate the Fiery 3850C, you can select the calibration set that corresponds to the typical printing jobs at your site. This same calibration set can be associated with one or more output profiles. (For more information on output profiles, see page 1-6.
3 3-5 Calibrating from the Control Panel using VisualCal When you examine the Test Page, keep in mind that all color patches should be visible, even though they may be very faint in the five percent and two percent range, and each color’s patch set should show uniform gradation from patch to patch as the color lightens from 100 percent to zero percent.
3 3-6 Color Calibration panel. The variable needed to recalculate the luminosity of the toners is determined in a slightly different way—you identify the black dot that best matches a 30% dot gain field. When all values have been entered, the printer’s toner density and luminosity settings are recalculated.
3 3-7 7. Using a spectrophotometer Press Yes to print the Gray Balance page. To reset the printer’s gray balance, follow the instructions provided on the Gray Balance page. When you have finished entering all values, the PRINT COLOR TEST screen appears. N OTE : If the Gray Balance page is printed after the Limits calculations have been made, the gray field on which the CMY patches appear on the Limits page will use the new density and luminosity calibration settings.
3 3-8 Color Calibration Setting up the spectrophotometer Before you calibrate the Fiery 3850C, you need to connect, configure, and calibrate the spectrophotometer to prepare for measuring the printed patches (see “Calibrating the X-Rite DTP32 densitometer” on page 3-28).

5 5-1 Chapter 5: Working with Color in Applications Working with color This chapter provides guidelines for defining colors in your documents to produce the results you want.
5 5-2 Working with Color in Applications • For color proofing, use an application that writes its own PostScript and define colors in RGB, CMYK, or choose colors from the PANTONE color library. Placed images can also be defined in RGB or CMYK. Choose the appropriate settings for print options affecting color output (see page 1-1). Color reference pages Fiery 3850C user software includes several types of color reference pages that let you see the range of colors that can be printed on your printer.
5 5-3 Office applications Office applications The Fiery 3850C must receive PostScript instructions to print an image or a document. Many applications do not create these PostScript instructions, relying on the printer driver to create them. Included in this category are most word processors, spreadsheets, and presentation applications. These applications use Windows Graphics Device Interface GDI to display and print when running Windows, and Apple QuickDraw to display and print when running Mac OS.
5 5-4 Working with Color in Applications Choosing colors in office applications Two RGB color reference pages, a Microsoft Word file and a Microsoft PowerPoint file, are provided with your Fiery 3850C user software. Print these files using different CRDs to see how the colors appear when printed to the Fiery 3850C. For best results, print the color reference page using the same print options you plan to use for your final document.
5 5-5 PostScript applications PostScript applications Most applications used for illustration, pixel editing, and page layout can create the PostScript information they send to PostScript printer or save in PostScript files. Illustrator, Photoshop, PageMaker, QuarkXPress, and Macromedia FreeHand are all PostScript applications. PostScript applications work with color in many different ways.
Working with Color in Applications Swatch color matching Fiery 3850C user software includes several color reference pages (see page 5-2). By choosing colors from these reference pages, you can ensure that you get the same color from your printer. For best results, calibrate the Fiery 3850C before printing the reference pages. N OTE : Swatch color matching does not match monitor colors to printed colors. For this, you must use a color management system and calibrate your monitor.
5 5-7 PostScript applications software can help ensure predictable results with colors chosen from the PANTONE color library. The information printed by the PANTONE Coated Color Reference depends on the setting of the Spot Color Matching setting. • On—Prints swatches of the closest equivalents of PANTONE colors your printer can produce. The equivalent PANTONE color name/number is printed below each swatch. • Off—Prints swatches of the CMYK equivalents of PANTONE colors as defined by PANTONE.
6 6-1 Chapter 6: Office Applications Working with office applications The Fiery 3850C ColorWise color management system provides complete color management for jobs printed from office applications. This chapter provides instructions for printing color documents from GDI and QuickDraw applications such as presentation, spreadsheet, and word processing programs. You can use these instructions with the Microsoft Office applications.
6 6-2 Office Applications Although there are no color management options within office applications, color conversions do occur when you import images or page elements that were not defined in RGB. To avoid such conversions with imported files, use the EPS file format for artwork that is to be imported into office applications. All RGB images placed in a document are affected by RGB Source and Rendering Style settings.
7 7-1 Chapter 7: Adobe Photoshop Specifying color settings This chapter covers features of Adobe Photoshop versions 6.x and 5.x for Windows and Mac OS. The illustrations show only Mac OS dialog boxes, but the information and instructions apply equally to the Windows version of Photoshop. Specifying color settings The following sections outline the recommended color settings for Photoshop 6.x and 5.x in a Fiery 3850C workflow.
7 7-2 TO Adobe Photoshop SPECIFY COLOR SETTINGS FOR P HOTOSHOP 6. X 1. Choose Color Settings from the Edit menu. 2. Select Advanced Mode. In Advanced Mode, a more extensive list of options is displayed.
7 7-3 3. Specifying color settings Choose the desired working space profile for each color mode in the Working Spaces area. Use the following guidelines for specifying working spaces: • For RGB, choose the profile for the default RGB color space used by the Fiery 3850C. In most cases, this is EFIRGB. Consider sRGB if you usually view images on a generic PC monitor or rely on a Windows operating system to manage color on your monitor.
7 7-4 Adobe Photoshop Choose a rendering intent from the Intent menu that will optimize the color quality of the conversion. For guidelines on choosing the rendering intent, see your Photoshop 6.x documentation. Select Use Black Point Compensation and Use Dither (8-bit/channel images) to optimize the quality of color conversions. 6. Clear the Desaturate Monitor Colors By and Blend RGB Colors Using Gamma options in the Advanced Controls area.
7 7-5 Photoshop 5.x should calibrate your monitor using the Adobe Gamma control panel and specify settings in the Photoshop’s Profile Setup, RGB Setup, and CMYK Setup dialog boxes before you begin working with images in Photoshop. N OTE : The Adobe Gamma control panel performs similar functions on both Windows and Mac OS computers. Adobe Gamma control panel You can use the Adobe Gamma control panel to create and customize ICC profiles for your monitor.
7 7-6 Adobe Photoshop Display the Adobe Gamma control panel by double-clicking its icon in either the Windows or Mac OS Control Panel. If you have not yet selected your monitor profile or want to customize your current profile, click the Assistant (Wizard on Windows) button.
7 7-7 Photoshop 5.x Profile Setup From the Photoshop 5.x File menu, choose Color Settings>Profile Setup. In the Embed Profiles area, select all boxes to embed the appropriate ICC profile when saving a file. By embedding a profile during the saving process, Photoshop can link a color space (working space) definition with that file for future use. When you open an image that already contains a profile, Photoshop can alert you as to which color space the file was saved in.
7 7-8 Adobe Photoshop RGB Setup Photoshop 5.x allows you to simultaneously use two RGB spaces, one for the monitor and one for the Photoshop RGB working space. The monitor RGB space setting does not affect the image data in the file; it affects only the way the image is displayed on the monitor. Even if an RGB image has been prepared with different monitor settings, it is still correctly displayed on your monitor, without changes to the original values in the file. From the Photoshop 5.
7 7-9 Photoshop 5.x The Monitor area shows the currently selected profile in the Adobe Gamma control panel. Select both the Display Using Monitor Compensation and Preview options. CMYK Setup From the Photoshop 5.x File menu, choose Color Settings > CMYK Setup. Check this option Select the Preview option. For CMYK Model, select ICC. Previous versions of Photoshop used Photoshop Separation Tables, and you can load them for Photoshop 5.x.
7 7-10 Adobe Photoshop It is often better to select the Black Point Compensation option. With many ICC profiles, this check box has no effect. However, when it does, it has a dramatic effect on the dark areas of your image. If you want this effect, leave Black Point Compensation; if not, clear the selection. ColorSync defaults You should have ColorSync 2.5.x or later installed on your Mac OS computer. The ICC profiles used by ColorSync are saved in System Folder:ColorSync Profiles.
7 7-11 Photoshop 5.x Defining colors You can choose colors in Photoshop with various color models, including HSB, CIE Lab, RGB, and CMYK. You can also choose named colors from the PANTONE Coated color library. For best results, use the color definition methods described in Chapter 5. Saving files for importing into other documents Before saving a file, perform any rotating, cropping, and resizing needed. This speeds processing when printing from the application in which the image is placed.
7 7-12 Adobe Photoshop In the EPS Options dialog box, choose binary encoding and do not select PostScript Color Management (see the following section for more information on PostScript Color Management). Do not include transfer functions or halftone screens. A TIFF preview is compatible with both Windows and Mac OS computers.
7 7-13 Photoshop 5.x Printing RGB EPS Files Saved with PostScript Color Management When you print an RGB EPS file that contains an embedded profile to the Fiery 3850C, the working space information from the embedded RGB profile can be used as an RGB source definition for Fiery 3850C CRDs. To use the source color space information from the embedded profile with Fiery 3850C CRDs, choose None as the Fiery 3850C RGB Source when you print.
7 7-14 Adobe Photoshop Printing RGB images Use the following instructions to print RGB images. Choose RGB Color as the color space Choose an encoding method Do not select PostScript Color Management Choose RGB Color from the Space pop-up menu. Any other setting causes Photoshop to convert image data to that color space before sending it to the Fiery 3850C. With the AdobePS printer driver for Mac OS, these options appear in the Adobe Photoshop pane of the Print dialog box.
7 7-15 Photoshop 5.x Choose CMYK Color from the Space pop-up menu. Any other setting causes Photoshop to convert image data to that color space before sending it to the Fiery 3850C. (With the AdobePS printer driver for Mac OS, these options appear in the Adobe Photoshop pane of the Print dialog box.) N OTE : If you choose JPEG encoding, save a backup of the original image with binary encoding until you see the printed results of the JPEG file.
7 7-16 Adobe Photoshop Printing CMYK images with Photoshop PostScript Color Management If you select a CMYK color space and decide to use PostScript Color Management from the Photoshop pane of the printer driver, Photoshop sends CMYK data to the Fiery 3850C along with PostScript color information defining this CMYK color space. Remember that when you select PostScript Color Management, a CRD will be used to perform color conversions to the CMYK color space of the Fiery 3850C.
7 7-17 Photoshop 4.x Photoshop 4.x A special feature of Photoshop allows you to save RGB EPS (PostScript) images that include independent source color space information. This feature is sometimes referred to as “PostScript Level 2 tagging” or “RGB tagging.” You define the source color space to apply to RGB EPS images by specifying a Monitor Setup in Photoshop.
7 7-18 Adobe Photoshop We recommend you use the EPS or TIFF file formats to save RGB images that will be imported into other documents and printed to the Fiery 3850C. EPS and TIFF files can be imported into virtually all page layout applications. Choose Photoshop EPS or TIFF In the EPS Format dialog box, choose binary encoding and do not include transfer functions or halftone screens. A TIFF preview is compatible with both Mac OS and Windows computers.
7 7-19 Photoshop 4.x Selecting options when printing You can print RGB or CMYK images from Photoshop. • When you print RGB images, you choose whether the conversion to CMYK data is performed by the Fiery 3850C (using a CRD), by PostScript (using PS Color Management), or by Photoshop (using Photoshop separation settings). • When you print RGB images, you can choose whether a color conversion is performed by the Fiery 3850C using a CRD or by Photoshop using Photoshop’s separation settings.
7 7-20 Adobe Photoshop N OTE : The Fiery 3850C Rendering Style option specified will take effect if the Fiery 3850C RGB Source Profile option is set to None. • If you select Print in CMYK, Photoshop performs a color conversion and sends CMYK data to the Fiery 3850C. With this setting, RGB Source, Rendering Style, and Spot Color Matching settings have no effect.
7 7-21 Photoshop 4.x RGB Source and Rendering Style settings have no effect on CMYK images. The Spot Color Matching setting is also irrelevant because Photoshop converts PANTONE colors to CMYK values when you work in CMYK mode. • If the image was separated for an offset press standard, apply the corresponding CMYK Simulation setting. For example, if the image is separated for SWOP, choose SWOP as the CMYK Simulation setting.
8 8-1 Chapter 8: Page Layout Applications Working with page layout applications This chapter provides instructions for printing color documents from Adobe PageMaker 7.x and 6.5, QuarkXPress 4.02, and QuarkXPress 3.32. Before printing from these applications, make sure the appropriate printer driver and the Fiery 3850C PPD are installed on your computer, as described in Getting Started. Working with page layout applications The following sections apply to all page layout applications.
8 8-2 Page Layout Applications Importing images EPS and TIFF are the recommended formats for images imported into page layout documents. Support for importing other file formats may be provided by individual applications. All RGB images placed in a document are affected by the RGB Source and Rendering Style settings. The Fiery 3850C color management system applies the specified RGB Source setting to all RGB data and then uses the specified Rendering Style (CRD) to perform a color conversion.
8 8-3 Adobe PageMaker 7.x and 6.5 for Mac OS and Windows CMYK simulation You can specify a CMYK Simulation profile for the job using the CMYK Simulation Profile print option (see page 1-6).

A A-1 Appendix A: Desktop Color Primer Desktop Color Primer This appendix covers concepts basic to printing in color, including: • Properties of color • Printing techniques • Using color effectively • Raster images and vector images • Optimizing files for processing and printing If you are already familiar with color theory and digital color printing, refer to the last section (“Optimizing files for processing and printing” on page A-10) for tips on optimizing files for printing.
A A-2 Desktop Color Primer Like the sun, most light sources we encounter in our daily environment emit a mixture of light wavelengths, although the particular distribution of wavelengths can vary considerably. Light from a tungsten light bulb, for example, contains much less blue light than sunlight. Tungsten light appears white to the human eye, which, up to a point, can adjust to the different light sources.
A A-3 Desktop Color Primer Hue, saturation, and brightness A color can be described in terms of three varying characteristics, called the HSB color model: • Hue—tint (the qualitative aspect of a color—red, green, or orange) • Saturation—the purity of the color • Brightness—relative position between white and black While the CIE chromaticity diagram (color example 2) conveys hue and saturation, a three-dimensional color model is required to add the brightness component (color example 3).
A A-4 Desktop Color Primer Subtractive (CMY and CMYK) color The subtractive color model is the basis for color printing and for color photographic prints and transparencies. While the additive color model simulates the visible spectrum of color by adding light of three primary hues, the subtractive color model starts with a “white” or neutral light source containing light of many wavelengths.
A A-5 Desktop Color Primer Printing techniques Until recently, most color printing was done on printing presses using one of several printing techniques—offset lithography, flexography, and gravure, to name a few. All traditional printing techniques require lengthy preparation before a print run can take place. Short-run color printing, including Fiery 3850C printing, eliminates most of this preparation.
A A-6 Desktop Color Primer Halftone and continuous tone devices Halftoning is used in offset printing to print each process color at a different intensity, allowing millions of different colors to be reproduced using only the four process colors. Depending on the required intensity of a given color, toner is placed on paper in dots of different size. The grid of dots used for each toner color is called a screen.
A A-7 Desktop Color Primer A few rules of thumb Try some of the following strategies for creating successful color materials: • Rather than applying colors indiscriminately, use color to aid comprehension. In presentations, graphs, and charts, use color to highlight patterns and emphasize differences. • In general, fewer colors work better than many colors. • Use red as an accent color. Red is particularly effective when used in otherwise monochromatic materials.
A A-8 Desktop Color Primer Once you have mastered the concept of the color wheel, you have a good framework for experimenting with color combinations. Many books targeted at graphic designers show groups of preselected color combinations. Some are organized by themes or moods, and some are based on a custom color system, such as PANTONE. The more you develop a critical facility for judging color combinations, the more you will be able to trust your own eye for color.
A A-9 Desktop Color Primer Raster images and vector images Two broad categories of artwork can be printed from a personal computer to a color printer: raster and vector images. A raster image, also referred to as a bitmap, is composed of a grid of pixels, each assigned a particular color value (color example 11a). The grid, when sufficiently enlarged, resembles a mosaic made from square tiles.
A A-10 Desktop Color Primer Optimizing files for processing and printing The following sections provide tips on how to create image files that produce the highest possible print quality while minimizing the processing time and disk space they require. Resolution of raster images While a 72-ppi raster image appears sharp on a monitor, the same image would likely appear pixelated when printed to the Fiery 3850C.
A A-11 Desktop Color Primer In this table, the shaded areas indicate that 200 ppi is typically the best trade-off between image quality and file size. However, higher resolutions (for example, 250 to 300 ppi) may be needed for offset printing, when quality is of the utmost importance, or for images containing sharp diagonal lines. To find the best image resolution for your purposes, make test prints of some raster artwork at different resolutions.
A A-12 Desktop Color Primer Scaling Ideally, each raster image should be saved at the actual size, and it will be placed into the document at the optimal resolution for the print device. If the image resolution is correct for the print device, there is no quality advantage to be gained by scaling an image down to a percentage of its actual size.
B B-1 Appendix B: Color Management Color Management This appendix provides information on controlling and managing color output in order to achieve predictable color results. It also discusses the basics of color management. Controlling printed color When working with color materials, whether they be presentations, illustrations, or complicated page designs, you make aesthetic decisions about the colors you use. Once you have decided on your goal, you then need to realize it in print.
B B-2 Color Management Maintaining printer consistency The factors described below affect print device consistency, as well as color fidelity and overall output quality. Paper stock and toner The paper and toner used by your printer can affect printed color. For best results, use the supplies recommended by the manufacturer of the printer.
B B-3 Color Management You need to account for the gamut of your print device when designing on a color monitor. When printed, colors that fall outside the print device gamut are “mapped” to printable colors. This process, referred to as gamut mapping, takes place when color data is converted or adjusted to meet the gamut requirements of a print device. The Fiery 3850C is specially designed to perform gamut mapping at high speed with high quality results.
B B-4 Color Management Color conversion Before a color document can be printed, the color data in it must be converted to the gamut of the print device. Whether performed by the Fiery 3850C or by a host-based CMS, the process of converting color data for a print device is the same: the CMS interprets RGB image data according to a specified source profile and adjusts both RGB and CMYK data according to a specified output profile, also called a destination profile by some color management systems.
C C-1 Appendix C: Importing Densitometer Measurements Importing Densitometer Measurements This appendix describes Simple ASCII File Format, which can be used to import density measurements from measurement devices. To use your own measurement data from an alternate densitometer, record your individual readings in a text file and structure it as described below.

Glossary additive color model blasting A system in which colors are produced by combining red, green, and blue light (the additive primaries). An RGB video monitor is based on an additive color model. An undesirable effect that occurs when excess amounts of toner, possibly combined with certain types of paper stock, cause objects in an image to spread beyond its boundaries as defined in the file. additive primaries Red, green, and blue light that is used in additive color systems.
G-2 Glossary color management system (CMS) composite printer System used to match color across different input, display, and output devices. Any output device that can print directly in color without first creating color separations. A composite print can be used as an early proof of an offset print job. color rendering dictionary See CRD (color rendering dictionary). color separation The process of separating a color image into the color components for printing—cyan, magenta, yellow, and black.
G-3 Glossary DCS (Desktop Color Separation) flexography A data file standard defined by Quark, Inc., to assist in making color separations with desktop publishing system; five files are created, four color files (one each for C, M, Y, and K) and a composite color preview file of the color image. It allows an image-editing application to perform color separation and pass it through to final output with its integrity intact. A printing technology that uses flexible raised-image plates.
G-4 Glossary GIF (Graphics Interchange Format) ICC profile A standard developed by CompuServe for bitmap graphics of up to 256 colors and used for posting photographic images on the Internet or intranet pages; rarely used for professional printing. An industry standard color profile format developed by the International Color Consortium (ICC) that describes the color capabilities, including the gamut, of a color device based on the differences between an ideal and the current device.
G-5 Glossary moiré photographic rendering An undesirable pattern in images made using halftone screens. Moiré can be caused by the improper line frequency of the screens, improper screen angles, improper alignment of halftone screens, or by the combination of a halftone screen with patterns in the image itself. A color rendering style that preserves tonal relationships in images.
G-6 Glossary presentation graphics rendering RGB A color rendering style that creates saturated colors but does not match printed colors precisely to displayed colors. It is appropriate for bright saturated colors used in illustrations and graphs. An additive color model that makes a range of colors by combining red, green, and blue light, called the additive primaries. Commonly used to refer to the color space, mixing system, or monitor in color computer graphics.
G-7 Glossary spot color substrate A color that is printed on its own separation plate when separations are specified. A spot color is printed using a custom ink for that color, in contrast to process colors that are printed using combinations of cyan, magenta, yellow, and black. In printing, the material upon which the job is printed. Status T A spectral response for graphic arts reflection densitometers defined by ANSI (the American National Standards Institute).
G-8 Glossary white point workflow The color temperature of any white light source, typically expressed in degrees Kelvin (for example, 6500 K, typical for the white of a monitor). The path a print job follows from creation to destination. A workflow may originate with an RGB scan imported to the client workstation and opened on the desktop in an image processing application, such as Photoshop.
