Allows your printer to emulate a monochrome or color plotter.

Monochrome GL 2

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
