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

MagentaY = [(1*0.3) + (0*0.59)

+ (1*0.11)]—41% gray

Cyan

Y = [(0*0.3) + (1*0.59)

+ (1*0.11)]—70% gray
