Allows your printer to emulate a monochrome or color plotter. Choices On: Sets the printer to monochrome (2 pen). Off: Sets the printer to color (8 pen). Note: 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 Default On Pen Color Defaults: Pen 1 = White Pen 2 = Black Pen 3 = Red Pen 4 = Green Pen 5 = Yellow Pen 6 = Blue Pen 7 = Magenta Pen 8 = Cyan
