function_ Description index Argument Range 5 Download Color 1 CMY Color Space Map 3 CIE Lab Color Space See MapID List (14739 bytes) 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. D-22 Modifying Output Color (Color LaserJet, 5, 5M, DeskJet) EN
