11-11 Managing color on the GA-1121
•On—The GA-1121 uses a built-in table or, with the Spot-On (available as Option), the Spot-On color dictionaries (see page 3-18) to generate the best matches of the PANTONE colors that your copier/printer can produce. The PANTONE number is printed below each swatch.
•Off—The GA-1121 prints swatches using the CMYK values recommended by Pantone, Inc. (and used by applications that provide PANTONE color libraries). The CMYK values used to generate the color, as well as the PANTONE number of the color, are printed below each swatch. These CMYK values are printed through the selected CMYK Simulation and Output Profile settings.
NOTE: This feature is not available with the PCL driver.
RGB Source Profile
The RGB source profile setting allows you to define the characteristics of the RGB data in your document so the appropriate color conversion can occur on the GA-1121. Commonly used monitor color spaces are available from the printer driver and from the ColorWise Pro Tools Profile Manager. For special needs, 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 GA-1121 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 output from the GA-1121 is consistent across platforms. The GA-1121 RGB Source Profile options are:
•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 computer monitor.
•Apple Standard specifies the definition of all standard Mac OS computer monitors.
