The File Menu

The File Menu lets you do the following:

• Create a new context for scanning

• Load a previously saved context

• Save a context for scanning as an extra copy

• Show the current context for scanning

• Exit ScanWizard Pro TX


The Context Concept

The “Context” feature in ScanWizard Pro TX has to do primarily with setting up scan jobs and customizing your scanning environment for increased scanning efficiency. It is a powerful tool to help you get the most productivity out of your scanner, especially if you do many similar scanning jobs.

A “context” is really a Mac OS folder that contains any number of scan job files and a ScanWizard Pro TX preferences file with information on these scan jobs. Think of a context as a complete scan setup or environment, with each context having its own characteristics, such as scan material (reflective, positive, or negative film), ColorSync profile selections, scan quality control, interpolation method, and others.

When you quit or switch to another context, the settings of the current context are automatically saved. You will have exactly the same setup when you run or switch back to this context, so there is no need to start from scratch.

You can set up as many contexts as your hard disk can hold. And because contexts are regular Mac OS folders, you manage them (e.g., copy, duplicate, or delete) easily by using the Finder.

The ScanWizard Pro TX context can be easily customized to your particular need and used for many applications, such as the following:

• Repeated or frequent use of project/job settings

• Saving different experiments on the same project/job

• Different setups involving scan material selections, CMS settings, scan jobs

• Various templates of a user's work

• Scanner sharing among multiple users

• Archiving of scan projects/jobs

• Proofing on prescans and adjustments before final scans


New ScanWizard Context

This command creates a new context folder with default settings for scanning.

Subsequent scan jobs are then stored in the newly created context folder. The newly created context also becomes the current context.

To create a new context:

1.

Choose New ScanWizard Context from the File menu.

2. Select your scan material from the Scan Material menu in the Preview window or from the Scan Material command in the Preferences menu.

2.

When the browser dialog box appears, create a new folder.

Load ScanWizard Context

This command loads a previously saved context folder. The loaded context then becomes the current context.

To load a context:

1.

Choose Load ScanWizard Context from the File menu.

2.

When the browser dialog box appears, select the folder to be loaded, and click the Select button at the bottom of the dialog box.

Save ScanWizard Context As

This command lets you save an extra copy of the current context to a new location. The settings of the current context are saved first and then copied and switched to the new location. This is particularly useful when you want to work on a new context based on the current context settings.

To save a context:

1.

Choose Save ScanWizard Context As from the File menu.

2.

When a dialog box appears, choose the folder where the scan jobs will be saved. Subsequent scan jobs are then saved to the specified folder.


Show Current Context Path

This command shows the current context for scanning. By default, the current context folder has the same name as your scanner model, and is located in the

Plug-ins folder of your image-editing software. When you load or create a new context folder, the loaded or newly created folder then becomes the current context.

To show the current context: Choose Show Current Context Path from the File menu.

Quit

This command lets you exit ScanWizard Pro TX.


The Scanner Menu

The Scanner Menu lets you:

• Show your scanner model or select a scanner if you have multiple scanners

• Get information about your scanner

• Get scanner information on the SCSI or FireWire chain

• Easily manage the scanners you wish to use with your system

• Perform special scanner controls unique to the scanner


Scanner Model

The scanner model (and its SCSI or FireWire ID number) is shown at the top of the scanner. If you have multiple scanners on your system, all the scanners are shown with their respective IDs, and the current scanner is indicated by a check.

Only one scanner can be accessed at a time. To switch among various scanners, select the scanner to be used.

The scanner displayed with its SCSI or

FireWire ID number. The current scanner is marked by a check

Current Scanner Info

This command provides information about your current scanner. When you choose this command, a dialog box appears showing the scanner model, the

SCSI ID number, and the firmware version.

Scanner Probe

This command shows the scanner information on your SCSI or FireWire chain.

If your scanner does not show in the Scanner Probe dialog box, make sure your scanner is properly installed, connected, and turned on, and then click the

Probe button. For details on connecting your scanner, refer to your scanner hardware installation guide.

SCSI / FireWire devices on your system (including your scanner)

Choose your hardware interface here

Click the Probe button to update scanner information on the SCSI or

FireWire chain


Scanner Driver Manager

The Scanner Driver Manager keeps track of the scanners being used on your system and the bus / ID numbers occupied by the scanners. By keeping a record of this information, the Scanner Driver Manager allows ScanWizard Pro TX to start up more quickly, as there is no need to look for scanners that are not available.

When ScanWizard Pro TX is run the first time, all connected scanners are added to the list.

To add a scanner:

Follow the hardware installation instructions for connecting a scanner to your system. You can then use the Scanner Driver Manager in ScanWizard Pro TX to add or include the connected scanner to your scanner list.

1. Go to the Scanner menu in the Preview window, and choose Scanner

Driver Manager . A dialog box will appear showing the current scanner list with the corresponding SCSI or FireWire bus/ID number.

2. Click the Find Scanners button. In case you have added new scanners, the newly found scanners will be appended to the scanner list. If a scanner on the list is not detected (not turned on, not ready, or removed from the system), the model will not be removed from the list but will have a question mark before it. See below for details on how to remove a scanner.

3. Click the Close button to close the dialog box.


Scanner Driver Manager cont.

To remove a scanner:

1. Choose Scanner Driver Manager from the Scanner menu.

2. Choose the scanner you wish to be removed from the list.

3. Click the Remove button.

4. Click the Close button to close the dialog box.

To update your scanner list:

The Update List button is used to refresh your scanner list. For instance, you may have three scanners on your system, with two of them currently turned off.

When you choose Scanner Driver Manager, the dialog box may show a question mark in front of the two scanners that have been turned off. In this case, simply click the Update List button, and the scanner list will be refreshed and show only the connected one on the list.

Clicking the Update List button produces faster results than clicking the "Find

Scanners" button. Update List simply searches the scanner models already on your list, while Find Scanners goes through all available scanner drivers and searches for scanners.


Scanner Controls

This command lets you use some of the special features of your scanner, such as lamp control.

Note: Not all scanner models support these features. If your scanner model is not supported, the Scanner Controls command will be grayed out in the

Scanner menu.

Lamp Control

This the power-saving feature of the scanner lamp to save energy and extend the life cycle of the lamp. By default, the lamp turns off automatically if the scanner is idle for 15 minutes. You can change the lamp idle time in your preferences or disable this feature completely by unchecking the Auto Power

Saving Mode check box.

By default, the lamp warm-up time is 3 minutes. A lamp warm-up dialog box will appear if you try to perform a scan or preview operation without the lamp having fully warmed up. If the lamp is not fully warmed up, the light intensity of the scanner may not be stable and may adversely affect the quality of your scanned image.

The current lamp status is indicated. You may specifically turn the lamp on or off if you wish. Please note that the lamp On / Off state is automatically controlled by the software, and no user intervention is necessary. You may want to do this manually if and only if you wish to turn on and warm up the lamp a few minutes before you actually finish your scan job editing.


The View Menu

The View menu lets you:

• Select an overview or prescan view of an image

• Magnify or reduce (zoom in / zoom out) the Overview image

• Resize the Preview window to fit

• Bring the Settings window to the front

• Show or hide the Info, Job Panel and Tag windows

• Show or hide the High and Low Value Markers

• Show the ScanWizard Pro TX splash screen


Overview & Prescan

These commands allow you to see the image obtained with the Overview and

Prescan buttons, respectively.

Clicking the Overview button will let the scanner do an overview of the slides in your scanner, and thumbnails of the images will appear in the Job Panel window. Clicking the prescan button will give you a prescan or high-resolution view of the selected image as shown in the Job Panel window. The Prescan image is helpful as it shows a higher-resolution view of the image and aids in the creation of a more accurate scan frame toward obtaining the final scan image.

The parameters for the Prescan image are determined by the settings in the

Prescan Setup command in the Preferences menu.


Overview & Prescan cont.

A. To obtain the Overview image: With the image(s) placed in your film holder and with the holder inserted into your film scanner, click the Overview button.

B. To obtain the Prescan image:

1.

Select the image to be prescanned by choosing the image thumbnail in the

Job Panel window.

2.

Click the Prescan button. The Prescan image will then be available for choosing in the View menu, as indicated by the title Prescan Image #1 .

3.

To obtain multiple prescan images: Press the Shift key and click the jobs to be selected in the Job Panel window. When you click the Prescan button, multiple prescans are created in the process, and the images will be available for choosing in the View menu, as indicated by the title Prescan

Image and numbered consecutively; e.g., Prescan Image #1, Prescan

Image #2, etc.

4. To select all scan jobs, click the Select All button.


Zoom in / Zoom out

These commands allow you to enlarge (zoom in) or reduce (zoom out) your view of the overview image. Only your view of the image is enlarged or reduced; the actual size of the image is not changed.

To use this feature:

• To enlarge your view, choose Zoom In.

• To reduce your view, choose Zoom Out.

Zoom in Zoom out


Resize Window to Fit

This command resizes the Preview window, which you may find helpful to do for conserving space on your desktop monitor (especially after you have enlarged the Preview window).


Choose the Resize Window to Fit command. You can also do this by pressing the Apple command + R keys simultaneously.

Resize before

Resize after


Bring Settings Window to Front

This command brings the Settings window to the forefront, which is useful if you have the Settings window hidden behind other windows or if you have a expanded your Preview window such that it covers the Settings window.

Show/Hide... Window commands

These commands allow you to switch between showing or hiding the Job Panel window, Information window, and Tag windows on your screen.

Show/Hide Low & High Value Markers

This command shows or hides the Low & High Value Markers in the Preview window. By default, the Markers are shown in the form of a circular crossbar. A white circle in the middle represents the Low Value (black point) Marker, and a black circle in the middle represents the High Value (white point) Marker.

About

This command displays the ScanWizard Pro TX splash screen and shows the program's version number.


The Preferences Menu

The Preferences menu lets you:

• Choose the correct scan material

• Choose the film size for your film holder

• Specify color matching parameters

• Set up White/black points settings

• Show/hide auxiliary cursor lines

• Control Prescan settings

• Create effects like invert

• Activate the smoked glass effect

• Set other options in the More Preferences command


Scan Material

This command allows you to select the correct scan material for use with

ScanWizard Pro TX. Choose from either:

• Positive transparencies, such as slides; or

• Negative film, such as the negative film you use for your camera.

To choose your scan material:

1.

Choose the Scan Material command in the Preferences menu. From the submenu that appears, select your scan material; a check will appear next to the selected option.

2.

Alternatively, you can click the Scan Material pop-up menu and then choose the correct scan material from the drop-down menu that appears.

Material popup menu


Color Matching Setup

Color Matching is an important feature of ScanWizard Pro TX that ensures consistent color — from the initial input stage when an image is captured by the scanner, to the final output stage when the image is output to your monitor or printer (through either the Kodak CMS or Apple ColorSync™ technology).

Color matching is a critical component in the imaging process, because the color space of your monitor is different from that of your printer (in terms of output devices), just as the color space for RGB mode is different from the color space for CMYK mode (in terms of image types). For this reason, color matching was developed to allow an equivalent "mapping" of colors from one device or from one color space to another, ensuring that no major color shifts occur in the transferrence process.

To use the color matching function of ScanWizard Pro TX:

The first time you launch ScanWizard Pro TX, you will be prompted to set up color matching for your scanner. You may also access the color matching parameters for ScanWizard Pro TX at any time in the future by choosing the

Color Matching Setup command in the Preferences menu.


Color Matching Setup cont.

A. Display using monitor compensation

This check box affects only the way the image data is displayed and not the image data itself.

B. Monitor

The monitor selection shown here is the monitor set in your Monitor Control

Panel. To verify this information, go to your System Preferences , then Displays .

Your selected monitor will be shown, which should be the same as the entry in this dialog box. This setting only affects how the image is shown on the screen

— not the final scanned image.

C. Native Mode RGB color matching

This option is available only for Native color space mode. This check box should generally be checked unless you want to scan raw color data, in which case you lose the compensatory effects of the Color Matching System. Take note that it is not desirable to scan in raw data and then perform ColorSync data conversion, which will not generate the correct CMS effect.

D. Embed ICC destination profile in scan image

This feature will enable ScanWizard Pro TX to embed the Destination ICC profile into the image data. The information will then be properly interpreted by any ColorSync-savvy application.


E. RGB Destination

This feature lets you select the ICC profile in the ColorSync folder for outputting images to the RGB color space. You may select from Scanner RGB,

Monitor, RGB printer (e.g., inkjet printers), a special color space, or the internal color space profile.

A large number of RGB profiles is supplied by ScanWizard Pro TX. If you do not see the ICC profile for your monitor or RGB device, contact your device manufacturer. To load a specific ICC profile from a different folder, click the

RGB profile button (beside the drop-down menu), and select the profile you need.

F. CMYK Destination

This feature lets you select the ICC profile in the ColorSync profile folder for outputting images to the CMYK color space. ScanWizard Pro TX has supplied a large number of CMYK profiles. If you do not see the ICC profile for your printer, contact your printer manufacturer. To load a specific ICC profile from a different folder, click the CMYK profile button and select the profile.

G. Preview check box

This immediately updates the Preview window image when a new color profile is selected, so that the preview image reflects colors consistent with the newly selected color profiles.

H. Profile Info

This lets you review the information on the currently used ICC profiles.


White/Black Points Setup

This command provides you with advanced controls for setting the clipping points for your white and black points, as well as determining the output levels for the white/black points on your printer.


1.

Choose the White/Black Points Setup command from the Preferences menu.

2.

As an alternative, you can click this command from the Color Correction

Menu. This is also the same thing as clicking the White/Black points tool in the Settings window and then clicking the Setup button from the dialog box that comes up. When the dialog box comes up, specify your preferences.

A. Auto Clipping

The Auto White Point Clipping and Auto Black Point Clipping fields allow you to specify the percentage by which the white and black points, respectively, can be clipped from the histogram. The clipping is done after you click the Auto button in the AIC White/Black Points dialog box.

For example, if you specify 10 percent as your White Point clipping value and then click the Auto button, the white point on the histogram is adjusted so that

10 percent of the color information is "clipped" or ignored. The resulting 90 percent information leftover is then remapped, resulting in an image with less highlight detail.

The same principle above applies to the Auto Black Point Clipping feature, which governs the black point for shadows.

These fields are normally used by more advanced users, and the features are taken care of automatically if you have set up Color Matching correctly early on in ScanWizard Pro TX.

LCH Color Mode


Native Color Mode

B. Output Levels

The Minimum Output Level lets you set the minimum output level of the black point. The higher the percentage value, the lower the contrast will be.

The Maximum Output Level lets you set the output level of the white point. The lower the percentage value, the lower the contrast will be.

LCH Color Mode Native Color Mode

C. High and Low Value Markers

This lets you adjust the settings that define the High Value Marker (shown as a black circle) and the Low Value Marker . The High Value Marker is shown as a black circle in your preview image, while the Low Value Marker is shown as a white circle. You can specify the range of the markers to either the entire preview (by selecting the “Overview or Preview image” option) or to only within the scan frame (by selecting the “Current Scan Frame”).

In the White/Black Points Setup window, clicking the “Preview” button will obtain instant results; clicking the “OK” button lets you exit from the Setup window and applies the High and Low Value Markers setting you have made to the preview image.

LCH Color Mode Native Color Mode


Cursor Auxiliary Lines

This command allows you to show or hide cursor auxiliary lines to help you define a scan frame or measurement off the rulers more precisely. The cursor auxiliary lines show only when the Scan Frame tool is selected.


1.

Choose the Cursor Auxiliary Lines command in the Preferences menu.

From the submenu that appears, select how the cursor lines will appear.

• On both the x (horizontal) and y (vertical) axis

• On the x axis only

• On the y axis only

• None (no cursor lines)

2.

Click the Scan Frame tool. When you move the pointer to the image, the cursor auxiliary lines will appear.

Cursor

Auxiliary Lines


Prescan Setup

The Prescan Setup command lets you set or specify various parameters related to the prescan image.

A. Auto detect scan frame

If this box is checked, the scan frame is automatically detected for you and the scan frame marquee encloses precisely the prescan image (the slide frame and unexposed parts of the film are ignored). This feature works only if Full Frame is selected for the "Prescan Scan Area" option.

B. Auto Focus

If this box is checked, the prescan process is will include the Auto Focus function before the actual prescan is carried out. The prescanned image will look clear and sharp, but the prescan process may be slowed down a bit.

C. Fast Prescan

If this box is checked, the prescan process is speeded up, but the resulting image is grainier. If unchecked, the prescan process is slowed down a bit, but the resulting image is of better quality.

D. Keep All Prescan Image(s) After Quit

If this box is checked, the preview images stay after you exit ScanWizard Pro

TX. Otherwise, all prescan images are deleted after you exit ScanWizard Pro

TX.


E. Prescan Scan Area

This option allows you to select what area of the image will be prescanned:

Full Frame , which includes the unexposed film area; or Scan Frame , which prescans only the image area enclosed by your scan frame.

F. Prescan Image Margin

This option allows you to specify how wide or narrow the margin around the scan frame is for the prescan image. Options are: Minimal, Small, Medium , and

Large . Smaller margins give you more room to capture the preview image, while larger margins will allow you to have more room to expand your scan frame.

This is helpful because selecting the exact scan frame (through the Scan Frame tool) can never be a completely accurate process, and what appears to have been selected by the scan frame when you view the image in the lowerresolution overview may or may not actually include the portion you wish. The margin — depending on how wide or narrow it is — can then provide a berth or allowance for extending the boundaries of the scan frame around the prescan image. Margin options include minimal, small, medium, and large.

G. Prescan Image Dimension

This option lets you specify how large the prescan image will be: Full screen

("screen" meaning your main monitor), 75% screen , 50% screen , and Fit

Current Preview Window . The larger the size, the higher the prescan resolution.

The maximum prescan resolution is the scanner's optical resolution.

H. Background Prescan

If checked, the background prescan function is enabled. You can assign a number of scan jobs to execute a prescan while carrying out other jobs in the meantime (e.g., performing color correction to other scan jobs). If unchecked, this function is disabled. Select also from the Completion Sound menu the type of completion sound desired after the background prescan is completed.


Invert

This command inverts images of all scan jobs. Take note that all scan jobs are inverted at the same time; you cannot invert an individual scan job alone.

When an image is inverted, the brightness value of each pixel is converted to its inverse value. In the case of 24-bit images, for example, a pixel in a positive image with a value of 255 is changed to 0, and a pixel with a value of 5 is changed to 250.

Original Inverted image


Choose the Invert command in the Preferences menu. A check appears next to the command when it is enabled.


More...

The More...

command shows the More Preferences dialog box, where you can specify other options for ScanWizard Pro TX. There are three tabs (General,

Final Scan, Orientation) with varying options under each tab.

A. General Tab

1. Auto Overview

If this option is checked, an automatic overview of the images on your holder will be performed if the holder is inserted into the film scanner, without you having to click the "Overview" button in the Preview window.

2. Smoked Glass Background

This option lets you apply a smoked glass background that makes your scan jobs stand out more clearly and allows you to focus on the scan jobs. This feature can also be used for multiple scan jobs to show their respective image modes (example: one job in color, another in B&W), as well as their imageediting settings.

A smoked glass background masks the areas outside of the relevant portion of the scan image.


3. Warn if No Holder is Inserted

If this option is checked, an error message will appear if you attempt to perform a preview or scanning operation and there is no slide holder inserted into your film scanner.

4. Working Color Space

This option lets you choose between the default LCH color space or the Native color space.

5. Thumbnail Size

This menu lets you choose the thumbnail size for the images displayed in the

Job Panel window. Select from 96 x 96 pixels or 128 x 128 pixels .

6. Scratch Directory

The scratch directory is the folder where ScanWizard Pro TX creates temporary files, with the temporary files deleted at the end of an operation. You should change to a different folder only if the scratch directory is located in a disk volume that is too small for scanning operations. To specify a new scratch directory, choose Other Directory...

from the menu.


More Preferences cont.

B. Final Scan tab

1. Auto Focus for Final Scan

If this box is checked, the prescan process is will include the Auto Focus function before the actual prescan is carried out. The prescanned image will look clear and sharp, but the prescan process may be slowed down a bit.

2. Scan Quality

This option allows you to select the image quality by controlling the scanner hardware and the maximum image processing depth.

• Speed: Choose this option if your primary concern during scanning is speed.

Image data is delivered faster and the image data is processed in 8 bits per channel.

• Quality: This is the default setting. Scanned data is delivered a little slower but in high quality, and the image data is processed in 8 bits per channel.

• Best Quality: This setting is available only to higher-depth scanners (10-, 12bit, or higher). Scanned data is delivered a little slower but in high quality, and image data is processed in maximum bits per channel (i.e., 10-, 12-bit, or higher), and then converted to the desired output depth. This special operation results in the best image quality possible.

3. Multiple Sampling

If this box is checked, the scanner will perform multiple sampling, a process that reduces random image noise and yields higher-quality images as a result.

Take note that this option is enabled only if you select Quality in the "Scan

Quality" menu. Enabling multiple sampling will also slow down your scanning as it takes the extra time to yield better-looking images.


4. Interpolation Mode

The interpolation mode controls the way ScanWizard Pro TX interpolates

(either expands or shrinks) image data. Interpolation always occurs when the scan resolution you select is different from the scanner's optical resolution. The trade-off is speed vs. quality. If your application requires higher quality, use Bilinear (Quality) mode, especially if you are scanning higher-resolution line art images.

1. Nearest Neighbor (Speed): When this option is selected, ScanWizard Pro TX will do the following:

• Expanding (when scan resolution is higher than optical resolution): Linear interpolation is used (i.e., makeup pixels are created by using the average of the neighboring pixels).

• Shrinking (when scan resolution is less than optical resolution): Pixel drop is used to match the resolution.

2. Bi-linear (Quality): When this option is selected, ScanWizard Pro TX always scans in a high-enough resolution and then applies a bi-linear interpolation algorithm to expand or shrink image data. This is a complicated mathematical formula, and thus, takes longer to process.

C. Orientation

Three choices for orientation are each provided for slides, film strips, or APS film. The orientation choices are None , 90 degrees counterclockwise , and 90 degrees clockwise . These options govern how your slides are oriented when new scan jobs are created; i.e., as you insert a different holder into your film scanner and as the system asks if you wish to use "current" settings or "new" scan job settings.


The Correction Menu

The Correction Menu lets you use the Advanced Image Correction (AIC) features of ScanWizard Pro TX. The commands in the Correction menu correspond to the AIC buttons in the Settings window.

For more information, see the section of the manual on Advanced Image

Correction.

The Help Menu

The Help menu lets you access on-line help for ScanWizard Pro TX and the

Microtek web site. The contents of this menu may vary and will depend on your scanner package.

Tag Windows tool

The Tag Windows tool lets you set the shadow (black) point and highlight

(white) point of an image.

It also creates tag windows, which are used to isolate and identify precise colors in a given image, providing a visible and retrievable record of color values. This way, ScanWizard Pro TX lets you pinpoint and “tag” the color on the image, showing you the original or “Before” values, as well as the corrected or “After” values following the application of image adjustment controls.

The Tag Windows tool is useful especially if you are making color adjustments based on known mathematical values, as the displayed color information provides a basis for knowing how close or accurate are the color changes that have been made.

Also in the tag window are the Magic Diamonds for adding or removing a color cast, as well as for setting the shadow / highlight point.

Overview, Prescan, Scan

The Overview button previews the images in the film holder and shows the overview images as thumbnails in the Job

Panel window.

The Prescan button previews in higher resolution the overview images as shown in the Job Panel window. Multiple prescans can be done if you have several selected scan jobs, and the prescans are done one after another in the order that they are listed in the Job Panel window. Options governing the prescan function can be found in the Prescan Setup command in the Preferences menu.

To obtain multiple prescan images:

1.

Press the Shift key and click on the jobs to be selected in the Job Panel window.

2.

Click the Presca n button in the Preview window.

Multiple prescans are created in the process, corresponding to the number of scan jobs defined, and you can then switch among the various prescan images.

The Scan button scans the images on your scanner and delivers the images to your image-editing software. The images that are scanned are the scan jobs that have been checked in the Job Panel window.


Rulers, Unit of Measurement

The rulers on the top and left sides of the Preview window help you with measurement and alignment, marking off measurement according to the selected unit (inch, pica, pixel, etc.).

The unit of measurement can be selected in two ways:

• Through the Unit box in the Settings window.

• Through the arrow at the corner where the rulers meet in the Preview window. The drop-down menu through this method also lets you format the text color and background color of your rulers.

The options for unit of measurement include inch , centimeter , millimeter , point , pica , and pixel . The pixel option is dimmed if the selected resolution unit is lpi.

Select the unit of measurement for the rulers in either the Settings window or the Preview window.


Preview Area and Eject button

The preview area is where the overview or prescan image appears. You can increase the size of the preview area to see more detail in your image.

Take note of the following:

• When you perform an overview, the overview image size is determined by the current preview area dimension. The bigger the preview area, the higher the preview resolution.

• When you perform a prescan, the prescan image size is determined by the settings in the Prescan Setup dialog box.

Another helpful feature in the Preview window is the Eject button located at the end of the Toolbar. The Eject button is used to eject the film holder from your scanner.

Type

The Type box shows you the image type of the current scan job. ScanWizard

Pro TX allows direct scanning in the following color spaces described below.

A. RGB: RGB (Red, Green, and Blue) images use three colors to reproduce up to 68.7 billion colors. Because scanners and monitors are RGB devices, the

RGB color space is the most commonly used space for capturing and displaying images. The 48-bit option can be used with image-editing software (such as Adobe Photoshop) that support 48-bit RGB image processing.

B. Grayscale: Grayscale images use shades of gray to simulate gradations of color or tonal values, and contain 8 bits per pixel. The 16-bit option can be used with image-editing software that support 16-bit grayscale image processing.

C. CMYK: CMYK images are made up of the standard four colors (cyan, magenta, yellow and black or K) for separated film or digital files used for sheetfed or web offset printing. CMYK mode instantly converts the scanner’s RGB input to the CMYK color space. CMYK images are fourchannel images, containing 32 bits per pixel.

D. Lab Color: Lab images are three-channel images containing 24 bits per pixel. Lab mode is useful for editing a pixel’s luminance but not its color values. Lab mode produces device-independent color and is recommended for moving images between systems or printing to a PostScript Level 2 printer.

E. Web / Internet Colors: This mode is useful for displaying images on the

Web or Internet. Output for the Web / Internet color mode in ScanWizard

Pro TX is 8-bit, 256 indexed color images in the sRGB color space.


F. 256 Colors (Default) / 256 Colors (Custom): These are single-channel images (8 bits per pixel) that use a color lookup table containing up to 256 colors. The file size is smaller for images in this mode. As an initial setting, selecting 256 Colors (Default) uses an Adaptive palette with Diffusion . If the 256 Colors (Custom) option is selected, the dialog box below appears.

• Palette: The Palette option lets you choose the method for creating the color palette table. Uniform uses a 6-6-6 fixed color palette table.

Adaptive (default) creates a color palette table from the more commonly used areas of the color spectrum that appears in the image.

• Dither: The Dither option can improve the color quality of the 256indexed color image for photographs or continuous-tone images, using a technique of mixing available colors to simulate missing colors.

None provides no dithering. Pattern uses a structured pattern to simulate missing colors. Diffusion (default) uses the error diffusion technique to dither colors and produces the best quality for 256 colors.

G. Line art: Line Art images are made up of one bit of color (black or white) per pixel. Few editing options are available in this mode, but this mode is useful for images consisting purely of black and white or even single colors, such as mechanical drawings, blueprints, or fine-line illustrations.

H. Black-and-White Diffusion: This is a single-bit black-and-white image dithered with error diffusion. The black and white pixels are arranged in a way as to “fool” the eye into seeing gray.


Resolution settings

The settings related to resolution include the resolution box, the resolution list box, and the resolution unit.

Resolution is the sampling of image pixels per measurement unit or the amount of pixel information stored in an image. Together, the image resolution and dimensions determine the file size of the image, which is measured in kilobytes

(KB) or megabytes (MB).

The resolution of an image is important in determining the quality of the output image. Resolution is also directly related to file size, and the higher the resolution, the larger the resulting file size will be.

When dealing with resolution, remember to distinguish between optical resolution and interpolated resolution.

Optical resolution is the "real" resolution as measured by the scanner's optics.

Interpolated resolution is software-enhanced resolution and can be useful for enlarging very small images or for printing line art to obtain superior results.

A. Resolution box

This shows the resolution setting. To set your resolution:

Enter a resolution setting in the Resolution edit box, then press Enter. If the value you enter is too high or too low, the maximum or minimum resolution value is entered for you instead.

Depending on the type of image you have selected (grayscale, color, line art, etc.), a default resolution is displayed in the resolution box. After you enter your own resolution value, this value is then recorded for subsequent use, until a new value is entered and takes over.

B. Resolution list box

This provides predefined resolution values for easier selection of the resolution setting.

To select your setting, press the up/down arrows next to the Resolution box, and choose your setting from the list box.


C. Resolution unit

The unit of measurement for resolution is in ppi (pixels per inch) or lpi (lines per inch). Take note that lpi settings are dimmed if the ruler unit is in pixels.

To select your resolution unit:

• Choose ppi if your scanned images are intended for on-screen display. In this case, you need not go higher than the target resolution of your monitor

(usually 72 dpi for Macintosh). A higher resolution value will simply increase the file size of your image without any perceptive improvement in image quality.

• Choose lpi if your scanned images are to be printed. If you choose 1x, for instance, your scanned image will be printed at 133 lines per inch, resulting in a 133-dpi image. At 1.5x, the image will be printed at 199.5 dpi; and at

2x, the image will be printed at 266 dpi. The Custom option allows you to set an lpi value of your own specification.

In choosing an appropriate lpi value, keep in mind that if the resolution is too low, the image becomes pixelized, resulting in a deterioration of image quality. (Pixelization is the process in which the Postcript language uses a single pixel's color values to create more than one halftone dot.) Conversely, if the resolution is too high, the file size becomes unwieldy, and your file ends up containing more information than the printer needs, slowing down the file transfer and the printing process.


Scan Frame and related settings

These settings allow you to adjust the various factors that affect your image, including the width and height of your image when it is first scanned (Scan

Frame settings), the Scaling factor (how big or how small the resulting scanned image will be), and the dimensions of the image when it is output (Output settings).

Locks

Scan Frame settings

Output settings

Scaling

The Scan Frame settings, Scaling, and Output Settings work closely with the

Locks beside them.

•

In the default settings of ScanWizard Pro TX, where none of the locks are in place, take note of the following:

Changing the Scan Frame settings (width or height) will change the Output settings

(width or height).

Note: When an illegal value is entered (e.g., the input width exceeds the scan frame size), the value will appear in red as a flag or warning indicating an out-ofrange value.

• Changing the Scaling will change the

Output settings (width AND height).

• Changing the Output settings (width or height) will change the Scan Frame settings (width or height).


A. Scan Frame settings

The Scan Frame settings (width and height) represent the area on the scan bed that you wish to scan.

To specify your settings, enter the dimensions manually in the width and height edit boxes; or use the Scan Frame tool to define or resize your scan frame.

Changes made in the Preview window are automatically displayed in the Scan

Frame setting edit boxes.

If you wish, you can also choose from a menu of predefined Scan Frame settings. To do this, point your mouse to the words "Scan Frame" in the Settings window, and choose the setting you wish from the drop-down menu that appears.


B. Output settings

The Output settings (width and height) represent the dimensions of the image when it is output to either the monitor or the printer. If the size of the image to be output is different from the size of the original source image, adjust the scaling percentage, or manually increase / decrease the output values accordingly.

If you wish, you can also choose from a menu of predefined Output settings. To do this, point your mouse to the words “Output” in the Settings window, and choose the setting you wish from the drop-down menu that appears.

• Add / Remove Custom Setting: These options let you customize and create your own output settings for use in subsequent scans.


C. Scaling

Scaling lets you create larger or smaller images from the original source image. Take note of the following:

• Keep the scaling at 100% if you are outputting at the same size.

• Reduce the scaling if you are outputting your image at a smaller size. Increase the scaling if outputting at a larger size.

To choose the scaling percentage, click the up/ down arrow next to the scaling box, or enter a value in the scaling edit box.

If you wish, you can also choose from a menu of predefined Scaling settings.

To do this, point your mouse to the words "Scaling" in the Settings window, and choose the setting you wish from the drop-down menu that appears.

• Film scale mapping: Choose your image material and the output dimension.

For example, “35mm to 5” x 7"” means your image source is 35mm film, and output size is 5" x 7".

• Add / Remove Custom Setting: These options let you customize and create your own image-mapping scale for use in subsequent scans.

Scaling is also affected by your resolution setting. When you change resolution and specify a value that has no exact equivalent for scaling, the scaling may be affected and adjusts itself to the nearest allowed value. For instance, if your resolution is 100, your scaling becomes 99 (instead of a full 100), because that is the closest scaling equivalent, given the resolution value.

D. Image Size

The Image Size field indicates how big the file will be when you accept the dimensions shown in the edit boxes, together with the resolution setting that you have selected. Size is calculated automatically. The resulting file size depends on the image type (color, grayscale, etc); resolution; and dimensions of the image.

E. Unit of Measurement

The Unit of Measurement lets you select the desired unit (inch, cm, mm, point, pica, pixel) for your image dimensions.

Important : Make sure you select the correct unit of measurement before entering any of the values for width or height in the Scan Frame Settings or

Output Settings.


A. Scan

Frame lock

Locks

The Locks control the behavior of the Scan Frame settings and the Output settings. A third Lock lets you keep the proportion for image width and height.

C. Keep Proportion lock

B. Output lock

A. Scan Frame lock

This lets you lock in the settings of your scan frame, so that the width and height dimensions of the frame are always preserved no matter where you move the frame in your preview image.

If you know the exact input size for your image, or if you wish to “lock” the settings of your scan frame to a particular size, enter the Scan Frame width and height values first, then click the Scan Frame lock .

Note: The Scan

Frame Lock and

Output Lock are each mutually exclusive. This means that only one lock can be used at a time.

Your scan frame will be “fixed” at those values, so even if you move the scan frame around the preview image, the dimensions of the frame itself will remain unchanged.

B. Output lock

This lets you lockin the values specified for the width and height of the image when it is output. For example, if you know the exact output size for your image, enter the output width and height values first, then click the Output lock .

The image will then be scanned and output at the values you specify.

Note: If any of the input values are changed after the lock is on, the scaling will be adjusted automatically to preserve the output dimensions correctly.

C. Keep Proportion lock

This lets you keep the proportion of the image width and height despite changes made to either setting, and thus preserves the aspect ratio of the image correctly. The Keep Proportion lock is automatically turned on when you enter values in either the Scan Frame settings or the Output settings.


Transform

The Transform command allows you to rotate and / or flip the image in increments of 90 degrees.

The effects of the Transform command will be seen in the Prescan image or are after you click the Scan button and scan the image in; the Transform effect is not shown in the Overview viewing mode.

To use the Transform command:

1.

Click the Transform button in the Settings window.

2.

From the options that appear, choose the degree of rotation you wish.

3.

Click the Scan button in the Preview window. When the image is scanned, it will be rotated or transformed according to the selected option.


Image Category

The image category function in ScanWizard Pro TX applies predefined settings to your image and brings out characteristics specific to that image type. This is helpful in providing a more accurate output image.

To select the correct image category, 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 characterstics of your original.

• None : No image category conversion.

• Standard : Used for an image not falling into any of the categories described below. You can also use this category for images of good quality (neither underexposed nor overexposed, with accurate color and tones).

• Landscape : Used for images with cool atmosphere with broad tonal variation and a wide hue range. Examples: Natural scenery; skyline with an expanse of blue sky; mountains and fields.

• Portrait (Skin Tones) : Used for images with dominant skin tones and midtone details present. Examples: Portraits and objects with fleece- or skinlike covering.

• Jewelry (Gold Tones) : Used for images featuring dominant gold / silver hues. Examples: Gold and silver jewelry, silverware.

• Sunsets : Used for images with warm reddish hues or a color cast reminiscent of sunsets. Examples: Scenes at dusk or twilight.

• Metallic Subjects : Used for images with broad highlight and shadow details but with very narrow mid-tone details. Examples: Audio equipment,

Cameras.


• High Keys : Used for images with broad highlight tonal variation but with less shadow detail. Examples: Snow-covered landscapes; wedding gowns.

• Low Keys : Used for images with broad shadow tonal variation but with less highlight detail. Examples: Nighttime scenery; dark suits and clothing.

• Underexposed : Used for images with compressed tonal variation particularly in the shadow areas, characterized by an overall dark appearance typical of underexposed positive film.

• Overexposed : Used for images with compressed tonal variation particularly in the highlight areas, characterized by an overall bright appearance typical of overexposed positive film.

• Custom Settings : These let you create, select, or delete your own custom image category settings for future use.

Image assigned “Standard” image category

In the example below, 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.

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) and not, in this case, for an original 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.

Image assigned “Overexposed” image category


Advanced Image Correction Tools

The Advanced Image Correction (AIC) tools form an integral part of

ScanWizard Pro TX. With the AIC tools, you can adjust or enhance images right from within ScanWizard Pro TX and preview the changes to your image even before you scan.

Before we go to the use of the AIC tools, we will briefly discuss the LCH color model, which is important for working with images in ScanWizard Pro TX.This

is followed by other information relating to the LCH model, including the availability of the AIC tools in LCH vs. Native color mode, and recommendations on a workflow for optimizing images.

The following topics are covered:

• The LCH Color Model

• AIC tools in LCH vs. Native Mode

• AIC tools and your image type

• Workflow for optimizing images

• How to access the AIC tools

• Elements of the AIC dialog box

• The Action buttons

• Using Custom Settings

• Discussion of the individual AIC tools


The LCH Color Model

One of the strengths of ScanWizard Pro TX 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.

Reference: The Advanced Image Correction Tools 67

AIC Tools in LCH vs. Native Color Mode

All the AIC 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. As discussed in an earlier section of the manual, you can select the color space of your choice in the Preference s menu | More...

Sliders

In Native color mode, the White & Black Points dialog box allows you to modify the histogram in your RGB, CMYK, or Lab channel. Channels can be modified individually or collectively

(when you select "All") in the Channel box.

Following the selection of your channel, you can move the black and white sliders below the histogram to set the shadow and highlight values, respectively. The edit boxes below the sliders will reflect those values.


Gradation tool


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 TX 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.

Click to create handles from which to drag and manipulate a portion of the curve . The more handles are created, the easier and smoother it is to manipulate the curve. To remove a handle, drag it off the graph or the grid.

More Tips on using the Selective Color tool

To move the From color sector without changing the hollow dot position, press the Shift key and click inside the sector. When the pointer changes to a hollow cross, drag the sector to a new position. You will see that the sector can only be expanded or contracted in a limited fashion, as it is constrained by the position of the hollow dot. If you need to move the sector around, you will also need to reposition the hollow dot, which then changes the Chroma and Hue (C&H) values.

From color sector To reposition From color sector without moving the hollow dot, press the

Shift key and click, and drag the sector around the hollow dot position. The sector cannot break away from the fixed position of the hollow dot.

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.

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.

For details on how to read the tone curve, see the section on how to use the

Gradation tool.

Check this box to ensure that for the

Unsharp Masking filter, the image displayed in the preview window simulates that of the final scan

Filter tool


The Filter tool is used to apply special effects to your images. Several filters are provided in ScanWizard Pro TX, including Blur / Blur More, Sharpen / Sharpen

More, Emboss, Edge Enhancement, Gaussian Blur, and Unsharp Masking.

In using most of the Filters (except Unsharp Masking), the image you obtain in the pr eview window may differ from the way the image appears when you finally scan it in. For the Unsharp Masking filter, the final scan result can be simulated and previewed, either from the thumbnail on the filters dialog box or from the pr eview image in the Preview window.

Keep in mind too that the appearance of the image in the preview window and how it is affected by a filter will depend on the resolution of the image. The higher the r esolution, the less obvious the effect of certain filters (such as Blur).

Choose the filter you want from this area

Check this box to apply the filter effect to the

Lightness "L" channel (for

LCH mode only)


A. Blur : The Blur filters eliminate noise in the parts of the image where significant color transitions occur. These filters decrease the contrast between adjacent pixels, making the image appear hazy and out of focus.

Blur smooths out the transitions by lightening pixels next to the hard edges of defined lines and shaded areas. Blur More produces an effect three or four times stronger than Blur.

B. Sharpen : The Sharpen filters do the opposite of the Blur filters and increase the contrast of adjacent pixels, making images appear sharper and more focused. Both Sharpen and Sharpen More filters improve clarity, with the

Sharpen More filter having a stronger sharpening effect between the two.

C. Edge Enhancement: The Edge Enhancement filter gives greater contrast to edges. The filter can do this because edges are areas in an image where gray or color levels change abruptly. It is best to use this tool for impr oving geometrical contoured shapes.

Original Edge Enhancement

D. Emboss: The Emboss filter makes a selection appear raised or stamped by suppressing the color within the selection and then tracing its edges with black.

E. Unsharp Masking: The Unsharp Masking filter adjusts the contrast of edge detail and creates the illusion of more image sharpness. This filter can be useful for refocusing an image that has become blurry from interpolation or scanning. The dialog box below appears when you choose Unsharp

Masking from the Filters menu.

Specifiy the degree of the filter's effect here.

The higher the value, the stronger the sharpening effect of the filter. Too much

Unsharp Masking will emphasize the noise in the image

This parameter determines the depth of surrounding pixels that will be affected. The larger the mask size, the stronger the sharpening effect of the filter

This parameter specifies a tolerance range to prevent overall sharpening that might generate noise or cause unexpected results.

The Threshold defines the required range of contrast between adjacent pixels before Unsharp Masking is applied. Only the pixels with the range of contrast between adjacent pixels before sharpening is applied to an edge. A lower Threshold value produces a more pronounced effect

This parameter pertains to how the Unsharp Masking filter affects pixels which are darker than their adjacent pixels. By default, a value of 100 is specified for this field. The higher the value, the darker the edge around the lighter areas and the more pronounced the

Unsharp Masking effect is

This parameter pertains to how the

Unsharp Masking filter affects pixels which are lighter than their adjacent pixels. By default, a value of 60 is specified for this field. The higher the value, the lighter the edge around the darker areas and the more pronounced the Unsharp Masking effect is.

Original Unsharp Masking


F. Gaussian Blur: The Gaussian Blur is used to defocus an area of the image where significant color transitions occur or where noise exists, and the filter produces a hazy effect. "Gaussian" refers to the bell-shaped curve that is generated when this filter adjusts the color values of the affected pixels. The dialog box below appears when you choose Gaussian Blur from the Filters menu.

This parameter determines the depth of the surrounding pixels that will be affected. The larger the mask size, the stronger the blurring effect of the filter

This parameter allows you to specify a tolerance range or a field of contrast between adjacent pixels before blurring is applied. Blurring is applied only when pixel differences are below the Threshold value. The smaller the Threshold value, the weaker the blurring effect

This parameter specifies the degree of the filter's effect.

The higher the value, the stronger the blurring effect of the filter

Brightness & Contrast tool

(Native color mode)

The Brightness & Contrast tool lets you control the brightness and contrast levels of the entire image. Increasing the brightness makes all tones in the image lighter. Contrast, on the other hand, is the range between the darkest and lightest shades in the image, and increasing the contrast makes greater separation between the darkest and lightest areas of the image.

Note: Individual channel adjustments for brightness and contrast are not suppor ted. For RGB color images, the same effect applies to all channels. For

Lab color images, brightness and contrast applies only to the L (Lightness) channel.

Drag the sliders or enter values to change

Too much brightness can make an image look washed out, while ver y low brightness levels can make an image look very dark.

• Contrast: The Contrast contr ol lets you change the contrast setting. Too much contrast can make an image look like a photocopy of a picture with little or no gray shades. Too little contrast can make an image look dull and flat.


Color Correction tool

(Native Color Mode only)

To change the hue of an image, move the pointer in the color wheel to its new color position in the wheel

The Color Correction tool changes the hue and saturation of an image. You can also add a color cast to an image by simply moving the pointer to a particular place on the Wheel, or you can r emove an unwanted color cast by moving the pointer to a complementary color to balance out the tones. For instance, to remove a greenish cast from your image, move the pointer in the Wheel to the

"red" portion to neutralize the gr eenish hue of the image. The Color Correction tool is available only for RGB and indexed color images.

Picker: The Picker lets you pick a known neutral gray shade in your image and adjusts it to a closer, truer gray. The grays in an image may have a particular color cast which can be verified through the color information in the Information window

A gray that tends towards a reddish tint, for instance, will have its R value skewed higher than the G and B values. By using the Picker on a gray area, the gray is adjusted so that the RGB values become approximately equal

Angle: This shows the angle of the pointer on the Color

Wheel as measured in degrees, and a value can also be entered directly in the edit box to move the cursor to any point in the Wheel

Example: 0˚ corresponds to the color red on the Wheel,

60˚ to the color yellow, 120˚ to the color green, 180˚ to the color cyan, 240˚ to the color blue, and 300˚ to the color magenta

This lets you change the intensity of the hues

(colors) in your image. Use Saturation selectively, because increasing saturation will increase the intensity of all hues in the image

The Radius field shows the amount of shift towards a particular color and works in tandem with the Angle field. The Radius range extends from 0 located at the center of the Color Wheel and indicating the least concentration of color, to 1, located at the periphery of the Wheel and indicating the greatest concentration of color

Example: If your angle is 0˚ (red on the Color Wheel) and the radius is 1, this results in an intense reddish cast on the entire image.

The Angle-Radius feature works differently from that of the Saturation bar, which increases the saturation of all hues in the image without tending towards any particular color cast.


Threshold tool

(Line Art images only)

For Line Art images, the only AIC tool available is the Threshold tool.

Threshold is the dividing line between black and white; the range is 0 to 255, and the default is 128. Thus, gray levels below the Threshold are converted to black, while gray levels equal to or above the Threshold are converted to white, resulting in a high-contrast, black-and-white representation of the image.

Drag the slider to change the Threshold.

• To darken the original, drag the slider to the right. This increases the Threshold value so that more pixels are turned to black, resulting in a darker image.

• To lighten the original, drag the slider to the left. This lowers the Threshold value so that more pixels are turned to white, resulting in a lighter image.

Check this box if you wish to sharpen your Line Art image

Aside from dragging the sliders, you can also enter a value in the Threshold edit box to change the Threshold

B. Color Input Meter: This displays the input (density) pixel values at the specific x/y location. Take note of the following:

• For all color image types (RGB, CMYK, or Lab), the density values of the raw image are displayed.

• For grayscale images, the gray (K) channel is displayed.

• For single-bit images such as line art, this section is disabled.


C. Color Output Meter: This displays the output values of the selected pixel at the specific x/y location. Take note of the following:

• The left part of the fraction is the Before value, or the pixel value before image correction.

• The right part of the fraction is the After value, or the pixel value of the final output image after all image corrections. In the example shown, the

After value is the same as the Before value, as the image was not corrected or adjusted in any way, leaving the colors unaffected.

The range of your output value will depend on the output image type. See the table below for more information.

Color Meter Options

The Color Meter options also let you choose the size of your sample display area.

For instance, if you choose 5 x 5 as your sample area, this means your RGB values will represent color information for a 5-pixel by 5-pixel area. If you choose 1 x 1 (the default), the color information pertains to a single pixel — the pixel in the middle of the sample area.

Color Meter Options

Sample Size display, with

3x3 option shown here

If you select Native color mode as your display, the Color Meter options let you choose whether you wish to display color information in numbers or percentages.

• If Value is chosen, the numbers represent values in the 0-to-255 pixel scale regardless of the bit depth of your output image. For instance, an R value of

23 indicates that the sampling size selected has a red color value of 23.

Value is calculated by multiplying the percentage by the constant 255 (value

= 255 x percent).

• If Percent is chosen, the numbers represent percentage of intensity (divided by 255). For instance, a G value of 35% indicates that the sampling size selected has a green color value to be 35 percent intense (out of 100 percent). Percent is calculated by dividing the constant 255 by the value

(percent = V/255). For CMYK images, the display is always in Percent.


Creating Color Tag Windows

Tag windows are used to isolate and identify precise colors in a given image, providing a visible and retrievable record of color values. With the use of the

Tag Windows tool, ScanWizard Pro TX lets you pinpoint and “tag” the color on the image, showing you the original or Before values, as well as the corrected or After values following the application of image adjustment controls. Within the Tag windows also are Magic Diamonds that can be used to set the black and white point for the image, as well as remove a color cast.

To use the tag windows:

1.

Click the Tag Windows tool in the Preview window, and click an area in the preview image.

2.

The tag window appears, displaying the x/y positions of the pixel selected by the Tag Windows tool, as well as the precise color value of the selected pixel. The color of the selected pixel is shown in the color strip at the bottom of the tag window.

Appendix A: More Color Matching Information

This section contains supplementary information on further steps you need to take to achieve color matching across your devices.

Calibrating your monitor

Calibrating your monitor to obtain the proper monitor profile is important for achieving higher precision in color matching. ICC profiles for your monitor may be created specifically by profiling your monitor through the following utilities:

• The Calibrate function under System Preferences...Displays.

• Any third-party calibration programs or hardware calibrator

You can also obtain your monitor profile by checking with the manufacturer of your monitor.

Setting up the System (Monitor) Profile

After creating or identifying the monitor profile, you need to select the moitor profile to make sure the image is displayed correctly.

Appendix B: Kodak Color Management System

This appendix is copyrighted by, and licensed from, Eastman Kodak Company.

KCMS Overview: Background Information

Everyone perceives colors differently. Even the same person’s perception can be affected by different lighting conditions. Different devices (input, display, and output) also interpret and define color differently and simply can’t create the same gamut (or “range”) of colors.

The goal of color management, then, is to help you get accurate, predictable color across all devices by managing, compensating for, and controlling these differences.

The Idea Behind Color Management

Each type of device reads, displays, or interprets color in a unique way. This unique interpretation is called a “device dependent color space.” And while there are groups of color spaces, such as RGB or CMYK each device is still unique within its group. For example, monitors display color in RGB, yet each monitor displays a unique version.

The CMS automatically translates between each device dependent color space— so the color data is accurate and understandable.

This chart shows the central role of the CMS in managing device dependent color spaces.

Reference: Appendix 111

How Color Management Works

The aim of color management is to preserve true color information by making up for the differences in the way devices communicate color. Your CMS does this by using a scientifically designed system including:

• A Color Matching Processor

• A Device-Independent color space, frequently called a Reference Color Space or Profile Connection Space (PCS), which acts as a Rosette Stone in the translation process

• Device Color Profiles (DCPs)

DCPs relate a device dependent color space to the Profile Connection Space.

The CMS uses the Color Profile to translate from one device dependent color space to another.

How CMS Translates between Devices

When you scan an image, a CMS uses the information about the scanner—stored in the Scanner Color Profile—to translate the RGB image from the scanner to the

Profile Connection Space. The CMS then uses the information about your monitor—stored in the Monitor Color Profile—to translate the image from the

Profile Connection Space to your monitor color space, where you see it displayed.

In this example, the scanner is the “source” device, and the monitor is the

“destination” device.


When you print the image, the CMS again translates the image data from the monitor’s RGB color space to the printer’s CMYK color space—using the information about both devices as stored in their Color Profiles.

So, although all of the devices in this example use different device dependent color spaces, the CMS is able to translate between them and produce accurate, predictable color.

What are Device Color Profiles

Color Management Systems use Device Color Profiles to interpret color data between devices. DCPs are a collection of one or more ICC Profile data files. ICC

Profiles contain color characteristics of a given device (input, display, or output).

ICC profiles conform to the International Color Consortium profile specification, allowing the same device profiles to be used across multiple platforms.

Where Do Color Profiles Come From?

Color Profiles are created by either Kodak scientists or other color professionals using specialized software packages, sometimes known as profile building tools.

Kodak scientists use sensitive, specialized equipment to measure the color characteristics of a representative example of each device, as supplied by the manufacturer, to determine the intrinsic properties of the device.

From these measurements they develop a “characterization” of the device, called a

Device Color Profile, for each make and model measured.

The Color Profile includes color tables that relates the device’s color space to a

Profile Connection Space, as well as information about key attributes of the device for use by CMS-based applications.

A Word about Source and Destination

People often get confused about what is the “source” of an image and what is its

“destination,” so let’s clarify this.

In general, the “source” of an image refers to where the image currently is, and the “destination” is where you want the image to go.

In CMS terms, “source” means the Color Profile used to bring the image data into the Profile Connection Space (PCS). “Destination” means which Color Profile is used to get it from PCS to the destination device. For example, when you scan in


an image, you want it to appear on your monitor. So the source is your scanner, and its related Color Profile, and the destination is your monitor, using its Color

Profile.

Likewise, when you open a Photo CD image, the source is the Photo CD, plus the

Color Profile that relates the color data to the PCS, and the destination is the monitor, plus the Color Profile that relates the PCS to the monitor’s color space.

Here’s another example: Let’s say you manipulate the image on your monitor screen, and print it.

The source this time is the monitor (plus the Color Profile that relates it to the

PCS), and the destination is a printer (plus the Color Profile that relates the PCS to the printer’s color space).

So, Source and Destination mirror a logical two-step process most Color

Management Systems use to translate images between device color spaces;

• The Source Profile brings the image into the PCS

• The Destination Profile connects the image from the PCS to the output device, such as a Monitor, Printer, or Proofer.

However, this is not the case with a Kodak CMS.

Kodak has patented its composition technology. This technology takes the Source and Destination Profiles and composes them into a single color transforming profile.

This technology adds significant improvement in the quality and performance of the Color Management System.

Note: You use the Source/Destination information when you setup or use your

CMS-based application, such as PageMaker 6.5.


Controlling UCR & GCR

Controlling UCR and GCR with Professional CMYK Profiles

In the final stages of color prepress production, the issues change: And your role changes with them. You become that of a professional separator. And it becomes a question of how skilled you are at making good films, films that run correctly on press, avoiding downtime, rework, and expense.

Kodak Digital Science Professional CMYK Profiles helps you with your separations. It expands your selection of undercolor removal (UCR) and gray component replacement (GCR) options, so you can produce correct, quality separations.

Some Background

It is difficult to print four wet layers of ink on top of one another. This is one of the physical constraints of the printing process.

In theory, if you printed a 100% of each CMYK layer, you would have 400%

Total Area Coverage (TAC). Real-world experience proves this to be impractical.

It is difficult to print jobs that have more than 340% TAC, and most printers feel more comfortable with 280% TAC.

Another area of practical concern is in how process inks are combined. Most printers can not produce a clear, dense black from cyan, magenta, and yellow.

Black is needed to produce better details, contrast, and to get a desirable density.

Adding black to CMY reduces ink coverage TAC, and thus improves the ability of paper to firmly hold each layer of wet ink, known as ink trapping.

So, from the concerns about ink coverage and ink combinations have come tried-and-true approaches to producing excellent films for excellent separations.

Two aspects of the offset printing process are undercolor removal (UCR) and gray component replacement (GCR).

UCR

Undercolor removal is the practice of removing quantities of yellow, magenta, and cyan ink from the dark neutral areas in a reproduction and replacing what was removed with an appropriate amount of black. Kodak implements UCR in its

Color Profiles within a TAC constraint: CMY gets replaced by the maximum amount of K up to the TAC limit—so you get the highest possible density.

The neutral center of both diagrams show different UCR/TAC settings. With UCR applied, less process inks and more black increases the density in the shadows.


Advantages & Disadvantages to UCR

Undercolor removal within a TAC constraint reduces the problem of printing four solid layers of ink, one on top of the other, while each previous layer is still wet.

Reducing the ink coverage, TAC, improves the ability of the paper to firmly hold each layer of wet ink.

Less ink means better control, and faster drying times. Also, replacing cmy ink with the less expensive black ink has proven more cost efficient on long runs that use more ink.

Also, blacks and neutrals that print black are not influenced easily by shifts in the chromatic inks which cause color casts in the shadow tones. Separations produced with greater UCR produce darker blacks which result in better shadow detail.

However, some printers don’t like high UCR because of on-press dot gain and contrasty rosettes.

GCR

Gray component replacement is a variation on undercolor removal. The theory is simple: Whenever amounts of cyan, magenta, and yellow are present in the same color, that color has a gray component. Some or all of this gray component can be printed with black ink while maintaining the original color appearances.

In contrast to UCR, GCR involves a more general color replacement, with black being substituted over all colors.

The neutral center of both diagrams looks the same. With more GCR applied, less color ink and more black ink produces the same color.


Advantages & Problems of GCR

The main advantage of GCR is it reduces the effects of variations on press, so when ink coverage varies, the colors become slightly lighter or darker, rather than changing hue.

Increased amounts of GCR also allows your printing company to use a somewhat higher proportion of black ink, thus reducing cost — which saves you money.

High levels of GCR and/or UCR expand the overall gamut, so darker and more saturated colors are achievable. However, with too light GCR you may not get as saturated a color as with higher levels of GCR.

Professional CMYK Profiles Package: What You Get From Them

Professional CMYK Profiles packages were developed for the serious professional concerned about productivity, quality separations, and color fidelity.

With Professional CMYK Profiles , you get six different UCR/GCR settings that conform to generic CMYK SWOP, Japanese Ink Standard, and Euroscale standards — Letting you select the best values for your printing conditions.

Any of these combinations give you the control you need to optimize your separations for your proofing and printing applications, reduce your printing costs, and minimize ink trapping problems on press.

However, check with your printer as to the optimal UCR/GCR setting to select for your printing conditions. The following pages list the settings for the three standards.
