D-6 Modifying Output Color (Color LaserJet, 5, 5M, DeskJet) EN
Non-Continuous Tone Algorithms
HP Color LaserJet 5 and 5M printers remap non-continuous tone
render algorithms into continuous tone algorithms. The following
remapping takes place:
User-Defined Dithers
The Download Dither Matrix command (?*m#W) can create a dither
matrix for one or all three primary colors, in effect providing halftone
screens. User-defined dither matrices can be used for optimizing the
printer's output capabilities when using device-dependent color
spaces. They are ignored for device-independent color spaces, since
the printer cannot be calibrated as is necessary for
device-independent color. User-defined halftones can be downloaded
for each component of the color space.
