Pen 0=White, Pen 1=Black, Pen 2=Red, Pen 3=Green, Pen 4=Yellow, Pen
5=Blue, Pen 6=Magenta, Pen 7=Cyan.
When set to on, this option tells the printer to map each pen to its
assigned color, then convert the color to a grayscale using the National
Television System Committee (NTSC) color standard for luminosity
coefficients (Additive System):
Y = 0.30R + 0.59G + 0.11B
Example of how to use the color standard formula:
WhiteY = [1*0.30) + (1*0.59) + (1*0.11)]—100% gray
BlackY = [0*0.30) + (0*0.59) + (0*0.11)]—0% gray
RedY = [1*0.30) + (0*0.59) + (0*0.11)]—30% gray
GreenY = [0*0.30) + (1*0.59) + (0*0.11)]—59% gray
YellowY = [1*0.30) + (1*0.59) + (0*0.11)]—89% gray
BlueY = [0*0.30) + (0*0.59) + (1*0.11)]—11% gray
MagentaY = [1*0.30) + (0*0.59) + (1*0.11)]—41% gray
CyanY = [0*0.30) + (1*0.59) + (1*0.11)]—70% gray
