1-6 GA-1120 Color Management select from the four rendering styles currently found in industry standard ICC profiles. GA-1120 rendering style Best used for Photographic—Typically results in less saturated output than presentation rendering when printing out-of-gamut colors. It preserves tonal relationships in images. Presentation—Creates saturated colors but does not match printed colors precisely to displayed colors. In-gamut colors such as flesh tones are rendered well; similar to the Photographic rendering style. Relative Colorimetric—Provides white-point transformation between the source and destination white points. For example, the bluish gray of a monitor will map to neutral gray. You may prefer this style to avoid visible borders when not printing full-bleed. Absolute Colorimetric— Provides no white point transformation between the source and destination white points. For example, the bluish gray of a monitor will map to a bluish gray. Photographs, including scans and images from stock photography CDs. Artwork and graphs in presentations. In many cases, it can be used for mixed pages that contain both presentation graphics and photographs. Advanced use when color matching is important but you prefer white colors in the document to print as paper white. It may also be used with PostScript color management to affect CMYK data for simulation purposes. Situations when exact colors are needed and visible borders are not distracting. It may also be used with PostScript color management to affect CMYK data for simulation purposes.

1-7 Managing color on the GA-1120 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 GA-1120. 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 GA-1120 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 GA-1120 will be consistent across platforms. The GA-1120 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 PC monitor. • Apple Standard specifies the definition of all standard Mac OS computer monitors. • Other allows you to specify custom RGB source settings. If you choose Other as the RGB Source setting, you can choose settings for the Gamma, Phosphors, and White Point options. • Sources 1-10 specify the definitions you download as RGB source profiles. For more information about downloading RGB source profiles, see page 3-4.
