1-6 iR C2100/2100S Color Management
• 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
Chapter 4.)
If you are printing with the PostScript driver for Windows 95/98, the
name of each downloaded or custom profile is represented in the RGB
Source Profile setting pop-up menu. If you are printing with the AdobePS
driver from a Mac OS, Windows NT, or Microsoft PS driver from
Windows 2000 computer, downloaded or custom profiles appear as Source
1 through Source 10.
• None instructs the iR C2100/2100S to allow the RGB sources you defined
elsewhere, such as in the application, to be used. When you set RGB
Source to None, the appearance of colors will not be independent of the file
type. For example, RGB EPS files will look different from RGB TIFF files.
With RGB Source set to None, PostScript RGB data that contains a source
color space definition is converted using the CRD specified by the
Rendering Style option (see page 1-4). NonPostScript RGB data and
PostScript RGB data that does not contain a source color space definition
is converted using a general undercolor removal conversion method.
RGB Separation
The RGB Separation option determines how RGB colors (as well as Lab and
XYZ colors) are converted to CMYK. The name of this option is meant to be
descriptive, since the option defines the color spaces that will be used by the
iR C2100/2100S to “separate” the RGB data into CMYK values.
