[. . . ] Color Management Software Engineering, RDC Microtek International Inc. , Inside ScanWizard Pro for Macintosh August 8, 2000 Microtek RDC Software Documentation 1 Introduction Every color input or output device has its own gamut, i. e. A successful artwork for print or for online use relies on accurate color reproduction. ScanWizard Pro provides complete color management solution for scanning to let you achieve color consistency for your application. To reproduce color accurately, you will have to setup your color management system properly depending on the operating system and the applications you're using. [. . . ] To specify the RGB Destination profile: choose from the profiles provided in the list, or choose your own profile if you have others stored in your system. ScanWizard Pro enumerates all the ICC profiles found in the ColorSync Profiles folder and displays the found RGB profiles. If you have ICC RGB profiles that are installed somewhere else, click at the button at the right to browse and select your desired profile. Please pay special attention to the Scanner RGB menu item in the popup menu. With this selection, ScanWizard Pro returns RGB image data scanned with "linear" condition, which is the same condition that MSP uses to profile scanner. In other words, scanner RGB means image data uses the scanner profile as its destination profile, instead of profiles such as monitor or printer. There is a great advantage of this because it is one less color space conversion in the color matching process. The net results are the original scanner RGB data is preserved better. This is especially important for those who demand the minimal loss of data during color space conversion. Also, if you want to apply MSP profile in other application, you must select Scanner RGB as your RGB destination color space. This setting has no relationship with any settings in ColorSync control panel. 1. 2. 5 CMYK Destination This feature lets you specify the correct profile for outputting images to the CMYK color space. Subject: ScanWizard Pro Color Management Page 8 Microtek RDC Software Documentation To specify the CMYK Destination profile, choose from the profiles provided by ScanWizard Pro, or choose your own profile if you have others stored on your system. ScanWizard Pro comes with a rich set of CMYK profiles for various applications. They are not installed as default and you must run the ICC Profile Installer from your ScanWizard Pro CD. This will ensure that the scanned images displayed in the Photoshop match the preview images shown in the Preview Window of ScanWizard Pro. Please note that this function only effect the way images are view on the monitor and does not modify the image content. Ø RGB Color Matching: On Take note that if this box is not checked, your RGB images will not go through the color matching process, and you may obtain inaccurate colors as a result. Ø Embed ICC Destination Profile In Scan Image: On This feature will enable ScanWizard Pro to embed the ICC profile of the currently selected color space in the image data. The ICC information will be properly interpreted by Adobe Photoshop or any ColorSync-Savvy applications. Ø RGB Destination: Scanner RGB The Scanner RGB is the best choice because there is one less color space conversion in the color matching process than other selections. Minimal loss of data is resulted during color-space conversion. If you wish ScanWizard Pro to output directly to the Photoshop internal working color space, you may do so in a few simple steps: 1) in the File | Color Settings. . . | RGB dialog box, choose the desired RGB space, 2) click the Save. . . [. . . ] Otherwise, the 3rd party scanner profile will not be displayed. Select the profile and click Open button to select it. Please note that you may also select the 3rd party scanner profiles in the RGB Destination popup menu in the Color Matching Setup dialog box. This will work fine. 4. 2 Special Notes of Using Monaco EZ Profiles During our tests, we discovered that an error is displayed in the following settings when using a Monaco scanner profile: Ø Ø LCH working color space (in the More Preferences dialog box, ) and Scanner RGB in the RGB Destination popup menu (in the Color Matching Setup dialog box) This is because Monaco scanner profile does not support a reverse transform from LAB to Scanner RGB space, which is required by ScanWizard Pro.
