Why RGB Color Separations for Tricolor Gum?
To make color separations to print CMY from the RGB file, invert the RGB file, then split the channels and print them. This may seem counterintuitive to people who were taught the simplistic idea that RGB is for light and CMYK is for printing, but bear with me; inverting RGB is actually the most direct and accurate way to separations that print the CMY layers in a tricolor gum print. (To see why converting to Photoshop CMYK may not be as accurate) If you’ve taken any color photography classes, or adjusted color curves in Photoshop, you know that the additive primaries and substractive primaries exist in a complementary relationship to each other. Each is at one end of a continuum that its complement is at the other end of. So the more yellow, the less blue; the more blue, the less yellow and the same for the other two pairs of primaries. As my Color Photography 101 teacher drilled into my head again and again, Cyan = minus Red; Yellow = Minus Blue, etc. If you look at the values for a
