It turns out that if I choose Output Intended for Screen/Web in PDF Export, then the PDF looks like the Scribus document. When I choose "Printer", all the colours (not just black) become slightly washed out, as if I had reduced the opacity. It prints that way on my black-and-white laser printer as well. 1) Does it really matter whether I choose "Screen" or "Printer"? 2) Does it really matter whether I use RGB or CMYK? I am using a few basic colours: Red RGB(255,0,0) or CMYK (0,100,100,0) Black RGB(0,0,0) or CMYK(0,0,0,100) plus colours in an imported SVG file. That is, I have two test documents: one that uses only RGB and one that uses only CMYK. Scribus says that I am also using "White", but I cannot see where. After I removed unused colours, "White" remained, but I have not coloured anything white as far as I can tell. The PDF looks the same whichever format is used. Would it be OK to send one of my test .sla files? If yes, which one should I send? I don't know anything about colour profiles and things like that. I am just manipulating objects on the screen until I like what I see, so I could be making a very simple mistake somewhere. I recently upgraded from Ghostscript 8.57 (which I was using when I started designing the sign) to 8.60, but it did not help.
