About this Users Guide This manual provides basic information on the program and sketches out a variety of scenarios that illustrate ScanWizard’s versatility and how best to use the program for specific scanning tasks with applicable Microtek scanner. For a more detailed listing of individual features, please refer to the companion Reference Guide included in your documentation package.
2 Getting Started This ScanWizard Pro operates in two operating modes, Scan and Batch modes: 1. The Scan mode (or scan-to-application) “acquires” ScanWizard Pro from an image-editing software program such as the Adobe Photoshop. The output images are scanned and directly delivered (individually or in batches) to your image editing software for further processing. 2. The Batch mode (or scan-to-file) launches the ScanWizard Pro from desktop program icon or Windows Start menu.

The Descreen tool is used to remove “screens” or moiré patterns from appearing in images. Moirés are interference patterns that show up on your scanned images when you scan images from magazines and newspapers. Moiré patterns emerge as a series of crosshatches or screens crisscrossing in the image. In the example in previous page, the top image was scanned from a magazine, resulting in an undesirable moiré pattern. The solution: rescan the image using the Descreen tool.
4 Using the AIC Tools This section of the user’s guide describes the use of the various Advanced Image Correction (AIC) tools, which form an integral part of ScanWizard Pro. All the tools are available when you work in the default LCH color space, but a different set of tools is available when you choose to work in the Native color space. Included at the beginning of this section is a brief discussion of the LCH color model vs.
The LCH Color Model One of ScanWizard Pro’s strengths is its ability to let you work in the LCH color space. Unlike the RGB color model, which corresponds to the color space as defined in monitors and printers, the LCH color model is a more intuitive way of working with colors, based on the values of Lightness (the “L” in LCH), Chroma (C), and Hue (H).
Selecting LCH or Native Color Space ScanWizard Pro lets you choose the color space in which you wish to edit and work with color images. • Select LCH mode if you wish to edit or correct images in terms of color perception according to the human eye, based on the properties of Lightness, Chroma, and Hue. This is the default mode. • Select Native mode if you wish to edit or correct the individual RGB / CMYK channels of an image. LCH mode is the default working color space when you first starts ScanWizard Pro.
Workflow for Optimizing Images To prepare and optimize images for final scan, it is recommended that the AIC tools are used in accordance to their sequence (as they appear in the LCH Mode Settings window shown below). Following this order will significantly influence the overall quality of your images.
Adding a Custom Setting To the right side of each AIC tool is a custom pull-down menu that features predefined settings for the AIC tool. For instance, some of these settings include Automatic or No Correction. You can also add your own image correction setting for each AIC tool. That way, you can retrieve or load the setting at any time in the future. To do this, choose an AIC tool and make the adjustments you desire to the image. Then click the Add to Menu button in the AIC dialog box.
How to Choose the Correct Image Category ScanWizard Pro provides several pre-defined image correction categories which can be applied as shortcut auto-correction your image. To select the correct image category for your image, go to the Settings window and choose the option you wish from the Image Category menu. Select the image category that corresponds most closely to the image characteristics of your original.
Image defined as Standard image category In the example images at right, an overexposed original is shown in two different image categories. Because the original was overexposed to begin with, choosing the Overexposed image category had the result of neutralizing the exposure, resulting in a better image.
Using the Dynamic Range Tool The Dynamic Range tool is used to set the density capture range of the scanner and displays the density distribution (histogram) of the image to be scanned. The Auto range (default) feature automatically determines the Dmin (minimum density, lightest tone) and Dmax (maximum density, darkest tone) of the image, and sets the scanner capture range.
Use the Dynamic Range tool to set the density capture range of the scanner. In the example below, the original has a narrow image histogram skewed heavily to the right. In the corrected version, the dynamic range is adjusted more evenly or spread out toward the left, enhancing contrast to the image.
Using the White & Black Points Tool The White & Black Points tool is used to change the shadow and highlight points of an image. (See note on next page for additional descriptions.) By using this tool, you can manipulate an image to either bring out the highlights in a very dark image, or bring out more of the shadows in a very light image. The White & Black Points tool can also be used to neutralize the color cast in the highlight and shadow regions.
Use the White & Black Points tool to set the shadow and highlight points of an image, as well as to neutralize the color cast in shadow/highlight regions. In the example below, the original has a slight color cast in the shadow and highlight portions of the image. With the use of the auto neutralizing and auto adjustment features, the color cast is removed, and the shadows and highlights are remapped accordingly.
Using the Gradation Tool (LCH Mode only) The Gradation tool lets you adjust the midtones (the mid-level grays) of the lightness channel “L” of an image without altering the color itself. This is because even with changes to the luminance or lightness value, the chroma and hue values are kept constant. Original image To prevent color images from losing saturation when adjusting the lightness, ScanWizard Pro provides a Saturation Range option.
Use the Gradation tool to adjust the midtones of the lightness channel “L” of an image. In the example below, the original is underexposed, with the middle tones of the image being too dark. The corrected image shows the middle tones being brightened, but the saturation and hues of the image remain untouched.
Using the Color Cast Tool (LCH Mode Only) The Color Cast tool is used to eliminate any unwanted color casts in an image, as well as to add a color cast without altering the lightness channel “L” values. In the example here, the original has a slight cyan cast that makes the image look cold and unappealing. The solution: Remove the undesirable color cast. 1. Place the image to be corrected on your scanner. Original image 2.
Use the Color Cast tool to remove an unwanted color cast or to add a color cast without altering the lightness channel “L” values. In the example below, the original has a slight cyan cast to it. Using the Tag Windows tool and clicking on the “watch tower” of the fishing boat removes the unwanted cyan cast from the image.
Using the Saturation Curve Tool (LCH Mode Only) The Saturation Curve tool lets you increase or decrease the color intensity (chroma or saturation) of an image without altering its hue and lightness values. In the example here, the colors in the original are not as saturated as they should be, resulting in a dull, lifeless image. The solution: To increase the saturation or intensity of the colors and restore vibrancy to the image. 1. Place the image to be corrected on your scanner. Original image 2.
Use the Saturation Curve to increase or decrease the color intensity (chroma or saturation) of an image without altering the hue and lightness values. In the example below, the colors are not as rich as they should be (notice the slightly muddied wash to the overall image). The corrected image shows deeper, richer tones, resulting in a more vibrant, lifelike image.
Using the Selective Color Tool (LCH Mode Only) The Selective Color tool is used to perform color correction to a specific color range without altering the other colors in an image. This is done either to increase the visual impact of a color or to completely change the relationship of the targeted color(s) to the other colors in the image. In the example here, we want to increase the saturation of the sky and change the boat color but leave everything else untouched. 1.
Use the Selective Color tool to perform color correction to a specific color range without altering the other colors in an image. In the example below, the color of the blue sky is changed with an increase in saturation, but all other colors in the image are held constant and remain unchanged.
Using the Tone Curve Tool The Tone Curve tool is used to adjust the tonal distribution of each channel of an image. It functions very much like the Gradation tool, except that it provides additional functions to allow separate adjustments of the tones in each RGB or CMYK channel, depending on the image type. This tool is especially useful for correcting the “ink percentage” distribution (i.e., dot gain correction) in CMYK images.
Use the Tone Curve tool to adjust the tones separately or as a whole for RGB/CMYK images. In the example below, the original looks cold, with a preponderance of blue-green tones. The corrected version shows the image with adjusted tones in the yellow and magenta channels, resulting in a rosier, warmer look.
Using the Filter Tool The Filter tool is used to apply special effects to your images. Several filters are provided in ScanWizard Pro, including various Blur / Blur More, Sharpen / Sharpen More, Emboss, and Edge Enhancement. In the example here, the original is a bit blurry to begin with. The solution: Use the Unsharp Masking filter to increase sharpness in an image. 1. Place the image to be corrected on your scanner. Original image 2.
The Filters tool applies special effects to your images. In the example below, the Unsharp Masking (USM) filter is used to increase sharpness in the image and improve image quality.
5 Special Features & Advanced Scenarios This section of the manual touches on the special features of ScanWizard Pro and provides more advanced scenarios on how to use the program.
How to Edit Multiple Scan Jobs ScanWizard Pro lets you edit multiple scan jobs at the same time, increasing your efficiency in using the software. In the scenario below, each scan job has its own image type setting (RGB, CMYK, Lab Color) and its own resolution setting (from 100 to 300 dpi). With multiple job editing, you can select all the jobs and then change their image type and resolution in a few quick steps, and then, say, apply a filter to all the images. 1.
