D-22 Modifying Output Color (Color LaserJet, 5, 5M, DeskJet) EN
1
For the original Color LaserJet printer, the color treatment arguments were slightly
different: (0 — Process Blue, 1 — Vivid, and 2 — Business Blue).
The following paragraphs describe the function_index values and
their arguments.
Lightness
Negative values darken (unlighten) the image, text or graphics color,
but do not have any effect on black or white data. Positive values
lighten the image. Zero turns the lightness adjustment off. This
function index requires three data bytes.
Saturation
Negative values desaturate (add gray to) the image, text or graphics
color, but will not have any effect on black or white data. Positive
values increase the amount of saturation, making the image more
vivid. Zero turns the saturation adjustment off. This function index
requires three data bytes.
Scaling
Pixel replication is a backward-compatible scaling algorithm. Bilinear
interpolation is a high-quality scaling algorithm for smooth-edge
interpolated scaling. Modified bilinear scaling only interpolates when
it is best to do so. This function index requires three data bytes.
Select Treatment
This value specifies which color treatment mode to use for rendering
the next job.
