Pro? ScanWizard Pro (version 6.0 or later) is an advanced scanner controller program that is designed and engineered to provides many powerful, professional-level features for scanning with Microtek ScanMaker and Artix scanners. One important feature of ScanWizard Pro is that it lets you work in the LCH color space, which is based on the LCH (Luminance, Chroma, Hue) model of colors. The LCH model is a more intuitive way of editing and working with colors because it defines colors the way we understand them -- based on the properties of brightness (how light or dark a color is), saturation (how rich or dull a color is), and hue ("red" as opposed to "blue"). Another important function of ScanWizard Pro is the batch scan feature, a separate but integrated program that lets you create and manipulate specific "contexts" or batches of jobs. With Batch Scanning, you can lay out your jobs beforehand, make adjustments to each scan, then start the scan when you are ready. The result? A tremendously improved workflow and savings in time, with the additional advantage of being able to call up the various "contexts" or batch jobs when required. A Powerful New Software With ScanWizard Pro, you can achieve a new level of efficiency in scanning. The many powerful tools of the program work together to help you obtain the superior color images you need, as well as provide you with the flexibility to adjust or improve the images as needed. And as you become increasingly familiar with the program, you will see how ScanWizard can open up a whole new vista for organizing your workflow and boosting your scanning productivity in as many ways as your creative imagination will allow.

ScanWizard Pro for Windows Users Guide 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. Introduction 1-5 English 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 output images are scanned and saved to files individually or in batches. Using the Scan Mode To operate ScanWizard Pro in the Scan mode, launch the image-editing software (e.g. Photoshop) of your choice. When the software program launches, go to the File menu, and choose the Import or Acquire command, depending on the software you are using (see sample menu from Photoshop below). This will automatically launch ScanWizard Pro, and the four major windows that form the interface of ScanWizard Pro will appear on your screen. Using the Batch Mode The Batch mode of operating ScanWizard Pro allows you to setup scan jobs individually or in "batches" and then start the scanning and save-to-file processes when you are ready to do so with a simple click of the Batch button. To operate ScanWizard Pro in stand-alone Batch mode, click on the ScanWizard Pro program icon on your desktop or go to the Start menu and simply follow the steps as illustrated below.

"Close" button Click to quit from ScanWizard Pro Color Matching The first time you launch ScanWizard Pro, you will be prompted to perform color matching for your monitor and printer. Color Matching is an important feature of ScanWizard Pro that ensures color consistency -- from the initial input phase when an image is captured by the scanner, to the final output process when the image is output to your monitor or printer. Color Matching allows you to gain the assurance that the colors captured by the scanner are consistent with those displayed on your monitor and will be reproduced as closely as possible when they are printed. You will be prompted with a dialog box (below) to select color matching settings immediately after you launch ScanWizard Pro the first time. This is dimmed when operating under LCH mode Monitor selection shown here is set at default profiles for monitor and printer CMYK printer profile. No default provided. Must select one if required You may redefine color matching settings whenever required. To do this, go to the Preferences menu in the Preview window, and choose the Color Matching Setup command. For more detailed information on color matching, see Color Matching for Advanced Users in the Appendix section of this manual.

After Descreen 3-10 ScanWizard Pro for Windows Users Guide 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. This will eliminate potential moirés from appearing in the resulting image as illustrated by the bottom image.

Basic Scenarios 3-11 English 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 Native color model, as well as other concepts important to optimizing your workflow. The scenarios provided are based on the Advanced Image Correction tools available through the LCH color model. · The LCH Color Model · Selecting LCH or Native Color Space · Workflow for Optimizing Images · Adding a Custom Setting · How to Choose the Correct Image Category · Using the Dynamic Range Tool · Using the Black & White Points Tool · Using the Gradation Tool · Using the Color Cast Tool · Using the Saturation Curve Tool · Using the Selective Color Tool · Using the Tone Curve Tool · Using the Filter Tool Using AIC Tools 4-1 English English 4-2 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). For instance, if you wish to change the color of the sky in an image to a darker blue, your own eye -- and your own judgment -- will be the guide to making those color changes. This is easier than, say, knowing the mathematical equivalent in RGB or CMYK values that would correspond to a "dark sky blue". The LCH model, in effect, makes it easier to comprehend colors as they are couched in the terms we are familiar with: Lightness (how dark or light a color is), Chroma or saturation (how rich or dull a particular hue of green is), and Hue (the property that distinguishes, say, the color red from the color blue.) In the LCH color model, colors of equal brightness lie on a single plane of the model, as shown below. Red and green lie opposite each other on the horizontal axis, as blue and yellow lie opposite each other on the vertical axis. On the color sphere shown below, you can see how the different LCH properties play out: · · · The different hues (red, green, yellow, blue) are spread around the sphere. The chroma (saturation) for each hue increases from the center of the sphere outward, with the most saturated colors lying on the edge of the sphere. The brightness values increase from the bottom of the model to the top. ScanWizard Pro for Windows Users Guide 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. To switch to Native mode, click on Preference from Preview window menu bar. Then click More... command from the bottom of the menu. The following dialog box will then display. From the dialog box, click on the Color Space Mode: list box and choose Native. The same procedure applies in switching from Native back to LCH color space mode. Using AIC Tools 4-3 English English 4-4 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. 1 Dynamic Range Manually or auto-adjust color balance (darkest to lightest tone) 3 Gradation Curve Manually or auto-adjust midtones of the Lightness (Channel L) 5 Saturation Curve Adjust image saturation by manipulating the saturation curve 7 Tone Curve Adjust tonal distribution of each RGB/CMYK channel in an image Descreen (Use randomly) Required only to remove moiré patterns from scans of newspaper/magazine originals LCH Mode AIC Tools 2 White & Black Points Manually or auto-adjust to fine-tune the white & black points and neutral gray 4 Color Cast Adjust gray balance by removing or adding color cast 6 Selective Color Manipulate a specific color without affecting other colors 8 Filter & Unsharp Masking Apply special effects to image and sharpen focus of blurry images with unsharp masking (USM) Native Mode AIC Tools The sequence is practically the same under Native Mode, except AIC Step 3 (Gradation) to Step 6 (Selective Color) of LCH Mode are not available in Native Mode. The later mode however, offers Brightness & Contrast (B&C) and Color Correction which are its nearest equivalent of the more advanced tools. ScanWizard Pro for Windows Users Guide 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. When another dialog box comes up, enter the name for the new setting. The new setting will appear in the custom pull-down menu of the Settings window for that particular AIC tool. Click to save current custom setting and add into AIC (Tone Curve in this example) predefined settings menu in the Settings window (see below) Saved custom setting (e.g., test4) is stored here. To retrieve and apply test4 to a new image to be subjected to a Tone Curve adjustment, click on this expansion arrowhead and choose test4 from the menu Using AIC Tools 4-5 English English 4-6 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. The selected image category could be used as a starting point of enhancing your prescan before proceeding to further optimize it with the AIC tools. · · None: No image category conversion (default). Standard: An image that does not fall into any of the d category described below. You can also use this category for images of good quality (neither underexposed nor overexposed, with accurate color and tones). Landscape: An image with cool atmosphere with broad tonal variation and a wide hue range. Examples include natural scenery, skyline with an expanse of blue sky, mountains and fields. Portraits (Skin Tones): An image with dominant skin tones and mid-tone details. Examples include portraits and objects with fleece- or skin-like covering. Jewelry (Gold Tones): An image featuring dominant gold / silver hues. Examples include gold and silver jewelry, silverware. Sunsets: An image with warm reddish hues or a color cast reminiscent of sunsets. Examples include scenes at dusk or twilight and images of the Grand Canyon. Metallic Subjects: An image with broad highlight and shadow details but with very narrow mid-tone details. Examples include audio equipment, TV sets, cameras. High Keys: An image with broad highlight tonal variation but with less shadow detail. Examples include snow-covered landscapes, wedding gowns, whitewashed structures. Low Keys: An image with broad shadow tonal variation but with less highlight detail. Examples include nighttime scenery, dark suits and clothing, a coal pit. Underexposed: An image with compressed tonal variation particularly in the shadow areas, characterized by an overall dark appearance typical of underexposed positive film. Overexposed: An image with compressed tonal variation particularly in the highlight areas, characterized by an overall bright appearance typical of overexposed positive film. · · · · · · · · · ScanWizard Pro for Windows Users Guide 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. Image assigned Overexposed image category The same original did not fare as well when it was assigned the Standard image category (too bright overall, not enough contrast), because this image category is best used for originals of fairly good quality (sharp, neither underexposed nor overexposed). In this case, the original is with flawed exposure settings. This example then shows the importance of choosing the correct image category that corresponds most closely to your original to obtain optimal results. Using AIC Tools 4-7 English English 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. In the example here, the original image has low contrast and a limited range of tones, as can be seen in the narrow image histogram. The solution; truncate or narrow the scanner's range of density to the actual density range of the image (or smaller). This would then redistribute the small density range of the image to the maximum range of the scanner output, and thus restore contrast to the image. 1. Place the image to be corrected on your scanner. 2. Click the Overview button to start an overview, and you will see the image appear in your Preview window. 3. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan view from the View menu. 4. Click the Dynamic Range tool in the Settings window. The Dynamic Range screen will then appear. 5. Adjust the Dmin and Dmax values to an optimized range. To do this, move the sliders to the boundaries on both ends of the histogram. 6. Click OK to confirm the correction. NOTE: In the default Automatic setting, ScanWizard Pro optimizes density capture range automatically. You only need to use the Dynamic Range tool if you wish to further enhance image contrast. Original image and lightness histogram without density correction, showing narrow tonal range Corrected image and lightness histogram with density correction, showing a broader tonal range 4-8 ScanWizard Pro for Windows Users Guide 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. 4 6 6 5 Using AIC Tools 4-9 English English 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. In the example here, we need to set the shadows and highlights, as well as correct the color cast on both highlight and shadow regions. 1. Place the image to be corrected on your scanner. 2. Click the Overview button, and you will see the image appear in your Preview window. Original image 3. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan view in the View menu. 4.

This helps to neutralize the color cast in the shadow and highlight areas of the image. 6. Click the Auto button. This will automatically set the optimal highlight and shadow points for the image. 7. Check the Preview box so that the image in the Preview window is updated with the latest image correction. The update is done in the background and so may take a few seconds to show. 8. Click OK to confirm the correction. Image corrected with White & Black Points tool 4-10 ScanWizard Pro for Windows Users Guide 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. 4 7 5 8 6 The shadow point is defined as the lightness value L in an image that is output as black (mapped to the Minimum Output Level), while the highlight point is defined as the lightness value L that is output as white (mapped to the Maximum Output Level). The default values of the Minimum Output Level and Maximum Output Level are L=5.0 and L=95.0, respectively. Using AIC Tools 4-11 English English 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. To prevent color images from losing saturation when adjusting the lightness, ScanWizard Pro provides a Saturation Range option. With this option, colors outside of a given chroma range are not affected by the manipulation of the gradation curve. In the example here, the original image is underexposed, with the middle tones of the image being too dark. The solution: Lighten the tones to brighten up the image. 1. Place the image to be corrected on your scanner. 2. Click the Overview button, and you will see the image appear in your Preview window. 3. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan view in the View menu. 4. Click the Gradation tool in the Settings window. The Gradation dialog box will appear. 5. Move the pointer over the curve, and drag the center of the curve to the left. This brighten up the midtones of the image. 6. Check the Preview box so that the image in the Preview window is updated with the latest image correction. The update is done in the background and so may take a few moments to show. 7. Click OK to confirm the correction. Original image Image corrected with Gradation tool 4-12 ScanWizard Pro for Windows Users Guide 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. 4 6 5 7 Using AIC Tools 4-13 English English 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. Click the Overview button, and you will see the image appear in your Preview window. 3. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan preview from the View menu. 4. Click the Color Cast tool in the Settings window. The Color Cast screen will appear. 5. Move pointer toward preview image (notice that the pointer turns into Neutral Eyedropper pointer). With the Eyedropper pointer, click the color cast that you wish to remove. In the example here, we click on the "watch tower" of the fishing boat to remove the unwanted cyan cast. 6. Check the Preview box so that the image in the Preview window is updated with the latest image correction. The update is done in the background and so may take a few moments to show. 7. Click OK to confirm the correction. Image corrected with Color Cast tool 4-14 ScanWizard Pro for Windows Users Guide 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. 4 6 8 5 Using AIC Tools 4-15 English English 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. Click the Overview button to start an overview, and you will see the image appear in your Preview window. 3.

The update is done in the background and so may take a few moments to show. 7. Click OK to confirm the correction. 4-16 ScanWizard Pro for Windows Users Guide 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. 4 6 5 7 Using AIC Tools 4-17 English English 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. Place the image to be corrected on your scanner. 2. Click the Overview button to see the overview image in your Preview window. 3. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan view from the View menu. 4. Click the Selective Color tool in the Settings window. The Selective Color dialog box will appear. 5. Select the From color or the color to be corrected. In the example, move the pointer over the preview image (notice that the pointer turns into Neutral Eyedropper pointer). Point the Eyedropper over the blue sky and click. (Steps 5 to 9 are repeated for the change in the ship's color. Click the New button to define a second color.) 6. Check the Show Affected Areas option to see the targeted color(s). 7. Adjust the color range to be affected (the Delta LCH values). To do this, drag the arc of the color wheel and the sliders of the lightness bar until only the sky's blue color is affected. 8. Enter the To color or the color that will take the place of the original. Enable the To color mode by clicking on the To color label prior to entering the color.

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. In the example here, the original image looks cold, with a decidedly blue-green cast to it. The solution: Increase the "ink percentage" of the yellow and magenta channels to bring out the warmer tones. 1. Place the image to be corrected on your scanner. 2. Click the Overview button, and you will see the image appear in your Preview window. 3. Select the area to be prescanned with the Scan Frame tool, then click the Prescan button to obtain a prescan image, and switch to the Prescan view in the View menu. 4.
