Color Modes There are four PCL 5 color modes:
Black and White mode
Simple Color mode
PCL Imaging mode
HP-GL/2 Imaging mode
All four modes create a palette. The palettes used in the
Black and White mode and Simple Color mode are not
modifiable. You can, however, modify the palettes in the
PCL Imaging and HP-GL/2 Imaging modes.
You can use more than one mode on the same page. For
example, you could enter the Simple Color mode to print a
headline and a bar chart, PCL Imaging mode to print a
raster photograph, and Black and White mode to print
some body text. Each mode is described in more detail in
Chapter 2, “Using Color Modes.”
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.
