CALIBRATION CALIBRATION Calibrating the Fiery EXP8000/50 ensures consistent and reliable color output. Calibrate the Fiery EXP8000/50 using ColorWise Pro Tools Calibrator with a densitometer or a spectrophotometer.
CALIBRATION About this chapter This chapter describes the procedures for calibrating the Fiery EXP8000/50 using ColorWise Pro Tools Calibrator with various color measurement instruments. The following table provides the location of each procedure.
CALIBRATION 33 Calibrating with ColorWise Pro Tools Calibrator ColorWise Pro Tools Calibrator allows you to calibrate the Fiery EXP8000/50 using the measurement method of your choice. Changing calibration has the potential to affect all jobs for all users, so consider limiting the number of people authorized to perform calibration. Set an Administrator password to control access to calibration (see Configuration and Setup).
CALIBRATION 34 3 Choose a method from the Select Measurement Method menu. 1 Calibration methods 1 Procedures for each calibration method are described in subsequent sections of this chapter. Expert mode Calibrator provides two modes: Standard and Expert. You can perform all essential calibration tasks while in Standard mode. Expert mode offers two additional options: Print Pages and View Measurements.
CALIBRATION With the Print Pages option, print Comparison Pages showing the results of the new measurements with any profile associated with the currently selected calibration set. You can create a custom Comparison Page and save it as a PostScript or Encapsulated PostScript (EPS) file called CALIB.PS. Print the file to the Hold queue of the Fiery EXP8000/50 from your application. You can also create a CALIB.PS file by renaming any job in the Hold queue using Command WorkStation (see Utilities).
CALIBRATION 36 If you deselect Apply to all calibration sets, you can choose to apply the current calibration to a selected subset of the calibration sets on the server. To specify which sets, click Customize, which opens the Apply To dialog box. Select or clear individual calibration sets, and then click OK. If any of the selected calibration sets are not associated with an output profile, a warning appears, but you can choose to apply the calibration measurements to that set anyway.
CALIBRATION 37 Calibrating with the DTP32 or DTP32 Series II Using the DTP32 or DTP32 Series II densitometer, you can measure color patches generated by the digital press and automatically download the measurements to the Fiery EXP8000/50. N OTE : Before you use ColorWise Pro Tools to calibrate the Fiery EXP8000/50, set up and calibrate the DTP32 or DTP32 Series II. For instructions, see the documentation that accompanies the instrument.
CALIBRATION 38 8 Click Measure. Follow the on-screen instructions to feed the measurement page through the DTP32. N OTE : The DTP32 Series II does not have an edge guide for the page. Position the page so that the strip to be measured is lined up directly under the alignment mark. The Status field displays instructions for selecting the port and feeding the measurement page through the DTP32 four times, once for each color strip.
CALIBRATION 39 Calibrating with the DTP41 Using the DTP41 spectrophotometer, you can measure color patches generated by the digital press and automatically download the measurements to the Fiery EXP8000/50. N OTE : Before you use ColorWise Pro Tools to calibrate the Fiery EXP8000/50, set up and calibrate the DTP41. For instructions, see the documentation that accompanies the instrument. TO CALIBRATE THE FIERY EXP8000/50 USING THE DTP41 1 Start Calibrator. For instructions, see page 33.
CALIBRATION 40 8 Click Measure. 9 If necessary, choose the appropriate COM port for the DTP41 from the Available Ports menu, and then click Start Measurements. 10 Feed the measurement page into the DTP41, starting with the cyan strip. Align the page in the measurement page slot of the DTP41 so that the appropriate color column is centered below the alignment mark. Insert the page about three inches, past the front idler rollers, until it rests against the rear drive rollers and you feel resistance.
CALIBRATION 41 12 Repeat the measurement process for the magenta, yellow, and black strips. A check mark appears on the circle of the color just read, and the Status field indicates the color was measured successfully. Use the Previous and Next buttons to reverse or advance to another step in the measurement sequence. 13 When the Status field indicates that all four color strips have been read successfully, click Accept Measurements. 14 Click OK in the Measure dialog box.
CALIBRATION 42 N OTE : For this calibration to take effect, the calibration set must be associated with one or more output profiles. The default calibration set is already associated with the default output profile. You do not need to make any new associations. 4 Click Print in the Generate Measurement Page pane. The Print Options dialog box appears. 5 Choose the appropriate options and click Print. Page Type: Choose 21 or 34 Sorted Patches or 21 or 34 Randomized Patches.
CALIBRATION 43 8 Check the settings and click Measure. The Information dialog box appears. 9 Place the ES-1000 in the calibration cradle. When you place the ES-1000 in the calibration cradle, white point calibration is used to calibrate the spectrophotometer and compensate for gradual drifts in the instrument. Make sure the sample aperture is in full contact with the white tile on the calibration cradle.
CALIBRATION 44 Allow about five seconds to slide the length of the strip. 16 Release the button when all the patches in the strip have been measured and you reach the white space at the end of the strip. When a strip is measured successfully, the dialog background color changes to green, and the cross hair moves to the next color. If the strip is not measured successfully, the dialog background color changes to red, and a message directs you to try again.
CALIBRATION 45 Understanding calibration The following sections describe important concepts and suggestions for understanding calibration. An overview of calibration Calibration generates curves that adjust for the difference between the actual toner densities (measurements) and the response expected by the output profile. • Measurements represent the actual color behavior of the digital press. • Calibration sets are sets of measurements that combine media and screen options provided for Calibrator.
CALIBRATION 46 Success in obtaining satisfactory print quality from the Fiery EXP8000/50 depends on many factors. Among the most important are establishing and maintaining optimal toner densities. The density is the measure of the light absorbed by a surface. By carefully regulating toner densities, you obtain consistent printed color. Even with a calibrated system, toner density is affected by the settings of digital press, humidity, and temperature. Density also tends to drift over time.
CALIBRATION 47 Scheduling calibration Calibrate the Fiery EXP8000/50 at least once a day, depending on the volume of print jobs. If it is very important to maintain consistent color, or your digital press is subject to wide fluctuations in temperature or humidity, calibrate every few hours. For optimal performance, calibrate whenever there is a noticeable change in print quality or printing results are not as expected.
SPOT-ON 48 SPOT-ON The Spot Color Matching print option automatically matches spot colors with their best CMYK equivalents so that spot colors can be simulated using the CMYK toner of the digital press. However, you may want to adjust the default CMYK equivalents to achieve a better match for your specific printing conditions. You can modify spot colors using Spot-On. In addition to managing “named” colors, Spot-On allows you to create a list of “substitute” colors.
SPOT-ON 49 Starting Spot-On To use Spot-On, you must specify the output profile associated with the Spot Color Dictionary that you want to edit. If you select Output profile X and redefine PANTONE 123 from 30%M to 50%M using Spot-On, you will get 50%M when you print a job with Output profile X. If you print a job with Output profile Y, you will get the original value.
SPOT-ON Spot-On main window The Spot-On main window list color groups that represent libraries of spot colors on the Fiery EXP8000/50. Tool icons for working with colors appear at the top of the window. 1 1 2 3 4 5 6 7 8 9 10 11 12 13 Output profile Save Upload Download Cut Copy Paste Close All Print Up Down Custom color group Default color group 2 3 4 5 6 7 8 9 10 11 12 13 By default, the Fiery EXP8000/50 includes several PANTONE libraries along with a System library.

COLORWISE PRINT OPTIONS COLORWISE PRINT OPTIONS The ColorWise color management system provides print options that affect the output of objects in various color spaces. By specifying the appropriate settings for each print option, you can obtain the expected results for your jobs. About this chapter This chapter provides an overview of the ColorWise management system, which controls color on the Fiery EXP8000/50 (see page 72). It also includes a detailed explanations of each print option.
COLORWISE PRINT OPTIONS Managing color on the Fiery EXP8000/50 To modify Fiery EXP8000/50 printing behavior, do any of the following: • Specify ColorWise options for an individual print job using the menus that appear in the printer driver. • Specify most ColorWise options as server defaults from Color Setup in ColorWise Pro Tools (see page 29). You can also set default values from Fiery EXP8000/50 Setup, as described in Configuration and Setup.
COLORWISE PRINT OPTIONS 73 N OTE : With PostScript 3, a PostScript job can include calibrated CMYK (or CIEBasedDEFG) data. The Rendering Style print option, which normally affects only RGB data, affects calibrated CMYK data as well. The RGB Source Profile setting does not affect calibrated CMYK data. ColorWise print options The following sections provide detailed explanations of the ColorWise print options and how these options affect print jobs.
COLORWISE PRINT OPTIONS 74 Black Overprint The Black Overprint option allows you to specify whether or not black text or black text and graphics, defined as RGB=0, 0, 0, or as CMYK=0%, 0%, 0%, 100%, overprints colored backgrounds. • Text: Black text overprints colored backgrounds, eliminating white gaps and reducing the halo effect or misregistration of colors. You can choose this setting only if the Black Text/ Graphics option is set to Pure Black On.
COLORWISE PRINT OPTIONS Black Text/Graphics The Black Text/Graphics option affects black text and vector graphics. Under most circumstances, set this option to Pure Black On. When Black Text/Graphics is set to Pure Black On, black colors generated by applications (for example, RGB=0, 0, 0 or CMYK=0%, 0%, 0%, 100%) are printed using black toner only.
COLORWISE PRINT OPTIONS 76 N OTE : PostScript applications, such as QuarkXPress, may convert elements defined as RGB=0, 0, 0 to four-color CMYK black before sending the job to the Fiery EXP8000/50. These elements are not affected by the Black Text/Graphics option. For more information, see Fiery Color Reference.
COLORWISE PRINT OPTIONS 77 CMYK Simulation Method The CMYK Simulation Method allows you to define your preferred CMYK-to-CMYK conversion technique. • Quick applies one-dimensional transfer curves to adjust output densities in the cyan, magenta, yellow, and black channels. This technique leads to eye-pleasing color output from your digital press because pure primary colors are not “contaminated” by other colorants.
COLORWISE PRINT OPTIONS 78 The following applications have been tested with Mac OS and Windows for compatibility with the Combine Separations option: • Adobe Illustrator • Adobe InDesign • Adobe PageMaker • Macromedia FreeHand • QuarkXPress For information about using the Combine Separations option with applications such as Photoshop, see Fiery Color Reference. Composite Overprint When overlapping objects are printed, the foreground object can either overprint or knock out the background object.
COLORWISE PRINT OPTIONS 79 Output Profile Because the output profile is applied to all data in the print job, make sure the profile you select is the right one for your job. The default output profile consists of a profile for your digital press that describes its color characteristics and a calibration target that describes the expected behavior of the digital press.
COLORWISE PRINT OPTIONS Rendering Styles The Rendering Style option specifies a CRD for color conversions. To control the appearance of images, such as prints from office applications or RGB photographs from Photoshop, select the appropriate rendering style. The Fiery EXP8000/50 allows you to choose from the four rendering styles currently found in industry standard ICC profiles.
COLORWISE PRINT OPTIONS 81 RGB Separation The RGB Separation option determines how RGB colors (as well as Lab and XYZ colors) are converted to CMYK. The name of this option is meant to be descriptive because the option defines the color spaces that are used by the Fiery EXP8000/50 to “separate” the RGB data into CMYK values.
COLORWISE PRINT OPTIONS 82 When you specify a setting other than None, because the color space definitions are overridden, the output from the Fiery EXP8000/50 is consistent across platforms. The Fiery EXP8000/50 RGB Source Profile options are as follows: • EFIRGB specifies an EFI-defined color space recommended for users who have no detailed information about their RGB data. • sRGB (PC) specifies the definition of a Windows computer monitor profile used as the default.
COLORWISE PRINT OPTIONS 83 Spot Color Matching The Spot Color Matching option provides automatic matching of spot colors with their best CMYK equivalents. • On: The Fiery EXP8000/50 uses a built-in table to generate the closest CMYK matches of spot colors your digital press can produce. (New tables are generated when you add new output profiles.) With Spot-On, the Fiery EXP8000/50 uses the CMYK matches determined through Spot-On (see page 48).
COLORWISE PRINT OPTIONS 84 Substitute Colors Spot-On allows you to create a list of substitute colors. These are colors that, when called for in a document by their RGB or CMYK values, are substituted with a different color having the CMYK values from the Spot-On color dictionary. This permits exact color control and overrides individual RGB and CMYK colors. To enable substitute colors for a job, select the Substitute Colors option.

IMPORTING DENSITY MEASUREMENTS 91 IMPORTING DENSITY MEASUREMENTS This chapter describes Simple ASCII File Format (SAIFF), which you can use to import density measurements from measurement devices. To use your own measurement data from an alternate measurement instrument, record your individual readings in a text file, and then structure the file as follows. Simple ASCII Import File Format This format describes Status T measurement data for import into the ColorWise Pro Tools Calibrator.
