Device-Dependent Color Spaces

The following PCL commands can alter color processing for device-dependent color spaces:

•Rendering Algorithm (?*t#J)

•Gamma Correction (?*t#I)

•Color Lookup Tables (?*l#W)

•Configure Image Data (?*v#W)

•Simple Color (?*r#U)

•Monochrome Print Mode (?&b#M)

Color lookup tables or gamma correction (which are mutually exclusive) can modify the mapping of input to output.

Device-Independent Color Spaces

The following PCL commands can alter color processing for device-independent color spaces:

•Rendering Algorithm (?*t#J)

•Gamma Correction (?*t#I)

•Color Lookup Tables (?*l#W)

•Configure Image Data (?*v#W)

•Viewing Illuminant (?*i#W)

•Monochrome Print Mode (?&b#M)

Device-independent color spaces are supported under the following conditions:

1The Configure Image Data command (?*v#W) configures the current palette and specifies a device-independent color space.

2The Render Algorithm command (?*t#J) is set to one of the following algorithms (see “Halftone Render Algorithms” in Appendix D for details):

•Continuous tone detail (?*t0J, ?*t16J)

•Continuous tone smooth (?*t15J, ?*t17J)

•Continuous tone basic (?*t18J, ?*t19J)

•Device best dither (?*t3J, ?*t5J)

•Error Diffusion (?*t4J, ?*t6J)
