Pure black, AFAICT, is defined by CMYK as 100% K, 0% C, M, and Y. There can be a problem in Scribus trying to get pure black as an end result, since and RGB with 0 for each value will probably not result in pure black. We've had a number of submissions to the list where it seems the sender gets obsessed with getting pure black, and consequently gets upset at not achieving it. In the end, I think it should come down to getting the visual color of black you want with the printed product rather than some absolute mathematically pure black. Greg
