Subcommands

RI is used to modify the final appearance of color data and is defined by the International Color Consortium (ICC). For more information on RI see the current level of the ICC Specification.

rendering intent parameter

Specify the rendering intent for the defined graphic (GOCA) object.

PERCEPTUAL

Perceptual rendering intent. It can be abbreviated as PERCP. With this rendering intent, gamut mapping is vendor-specific, and colors are adjusted to give a pleasing appearance. This intent is typically used to render continuous-tone images.

SATURATION

Saturation rendering intent. It can be abbreviated as SATUR. With this rendering intent, gamut mapping is vendor-specific, and colors are adjusted to emphasize saturation. This intent results in vivid colors and is typically used for business graphics.

RELCM

Media-relative colorimetric rendering intent. In-gamut colors are rendered accurately, and out-of-gamut colors are mapped to the nearest value within the gamut. Colors are rendered with respect to the source white point and are adjusted for the media white point. Therefore colors printed on two different media with different white points won't match colorimetrically, but may match visually. This intent is typically used for vector graphics.

ABSCM

ICC-absolute colorimetric rendering intent. In-gamut colors are rendered accurately, and out-of-gamut colors are mapped to the nearest value within the gamut. Colors are rendered only with respect to the source white point and are not adjusted for the media white point. Therefore colors printed on two different media with different white points should match colorimetrically, but may not match visually. This intent is typically used for logos.

cmr-lname

The CMR local name. This name must have been defined with a DEFINE CMRNAME command.

Note: This parameter must immediately follow the CMR keyword.

processing mode parameter

Specify the processing mode for the CMR.

AUDIT

CMRs with the audit processing mode refer to processing that has already been applied to a resource. In most cases, audit CMRs describe input data and are similar to ICC input profiles.

The audit processing mode is used primarily with color conversion CMRs. In audit processing mode, those CMRs indicate which ICC profile must be applied to convert the data into the Profile Connection Space (PCS).

INSTR

CMRs with the instruction processing mode refer to processing that is done to prepare the resource for a specific printer using a certain paper or another device. Generally, instruction CMRs refer to output data and are similar to ICC output profiles.

The instruction processing mode is used with color conversion, tone transfer curve, and halftone CMRs. In instruction processing mode, these CMRs indicate how the system must convert a resource so it prints correctly on the target printer. The manufacturer of your printer should provide ICC profiles or a variety of CMRs that you can use. Those ICC profiles and CMRs might be installed in the printer controller, included with the printer on a DVD, or available for download from the manufacturer's Web site.

LINK

This CMR defines a direct color conversion from an input color space to a device output color space; process the CMR as a link CMR. This processing mode is only valid for device link (DL) CMRs. The PPFA command RENDER is not used with device link (DL) CMRs as such CMRs specify the intended rendering intent internally. This function requires print server (PSF) and printer support which is in addition to the original CMR support.
