Color Guide This manual introduces you to the concepts and issues associated with printing to the ColorPASS Z5000 Color Server It outlines key workflow scenarios provides information on calibration and color profiles and contains application notes that explain how to print to the ColorPASS Z5000 Color Server from popular Microsoft Windows and Apple Mac OS applications This manual is one book in a set of documentation that also includes manuals for users and system administrators All the other manuals should be available at your site refer to them for a complete description of your ColorPASS Z5000 Color Server Note The term ColorPASS is used in this manual to refer to the ColorPASS Z5000 Color Server The ColorPASS supports the CLC5000 color copier The term copier is used in this manual to refer to this supported device About the documentation The Color Guide is organized to supply you with key information about managing the color output of your ColorPASS Chapter 1 discusses the ColorPASS s print options and how to get the best color results and Chapter 2 describes several effective workflows ColorWise Pro Tools are discussed in the next two chapters Chapter 3 covers Calibrator and other methods used to calibrate the copier and Chapter 4 takes you through the features of Profile Manager used to manage color profiles on the ColorPASS and Color Editor which lets you customize simulation and output p
13. Color Management RGB Source Profile The RGB Source Profile setting allows you to define the characteristics of the RGB data in your document so that the appropriate color conversion can occur on the ColorPASS Commonly used monitor color spaces are available from the driver and from the ColorWise Pro Tools Profile Manager In addition for special needs you can use ColorWise Pro Tools to download custom monitor or scanner profiles When you specify a setting other than None for the RGB Source Profile the ColorPASS overrides source color space definitions or profiles that other color management systems may have specified For example if you specified a ColorSync System Profile on your Mac OS computer the RGB Source Profile setting overrides it In cases where you do not want this setting to override another specified source color space choose the None setting When you specify a setting other than None for the RGB Source Profile since the color space definitions are overridden the prints from the ColorPASS will be consistent across platforms Below are the ColorPASS s RGB Source Profile options EFIRGB specifies an EFI defined color space recommended for users who have no detailed information about their RGB data sRGB PC specifies the industry standard definition for a generic Windows PC monitor Apple Standard specifies the definition of all standard Mac OS computer monitors Other allows you to specify custom RGB source se
