But my tests show that RGB-0/0-0 black as a colored rectangle is different from an RGB-0/0/0 black image. Even on screen it looks very different! When I export to CMYK-PDF and look at it in acroread8, it also looks _very_ different. It is not just some almost-indistinguishable difference, you notice it instantly. And I'm not going to try to print that. I only use two profiles: sRGB for all RGB, ISOcoated v2 for all CMYK. I only get a coherent appearance if I use a huge black image as background as opposed to a color (either CMYK or RGB, I couldn't find something that matched). Something in Scribus' RGB image -> CMYK workflow is different from it's RGB color -> CMYK workflow...
