Topic: Specifying a 1bpp black in multicolor image
I need to be able to send a color image to my printer where the black pixels are printed with a K resin panel. The printers driver takes images in RGB color space and sets any pixels that are 1 bpp black to be printed by this K panel. How can I do this, because if I convert the picture to 1 bpp black and white I lose all my colors, but if I don't, I never get good black?
Is there a way to have just the black 0, 0, 0 in a picture store at 1 bpp but the rest 24 or 32 bpp?
More specifically, what I would like is to have two images combined in one file where one of the images is full color and the other is 1bpp for K panel black. Is that possible? It seems that Word does this. I can put a full color image in a file plus type some text and the text that gets sent to the printer is 1 bpp so it gets printed with K while the image is still full color.
