Allows your printer to emulate a monochrome or color plotter.
Menu Administration/Emulations/HP PCL 5/Monochrome GL/2
Choices On, Off
On—Sets the printer to monochrome (2 pen).
Off—Sets the printer to color (8 pen). Since a
monochrome print system has two pen colors only
(black and white), grayscale patterns are substituted for
other colors.
The printer maps each pen to its assigned color, then
converts the color to a grayscale using the National
Television System Committee (NTSC) color standard for
luminosity coefficients (Additive System):
Y = .3R + .59G + .11B
Examples on How to Use the Color Standard Formula
White Y = [(1*0.3) + (1*0.59) + (1*0.11)]—100% gray
Black Y = [(0*0.3) + (0*0.59) + (0*0.11)]—0% gray
Red Y = [(1*0.3) + (0*0.59) + (0*0.11)]—30% gray
Green Y = [(0*0.3) + (1*0.59) + (0*0.11)]—59% gray
Yellow Y = [(1*0.3) + (1*0.59) + (0*0.11)]—89% gray
Blue Y = [(0*0.3) + (0*0.59) + (1*0.11)]—11% gray
Magenta Y = [(1*0.3) + (0*0.59) + (1*0.11)]—41% gray
Cyan
Y = [(0*0.3) + (1*0.59) + (1*0.11)]—70% gray
