Our church is fortunate to have a Xerox 560 with Fiery interface on campus. It’s workhorse of a machine that prints great color. Whenever I have a tech come in for maintenance, before he leaves I like to print a full tabloid sheet of each of the CMYK colors (Cyan, Magenta, Yellow and BlacK). It’s a easy test that can spot streaks, hickies and other mechanical printing problems BEFORE the tech leaves.
The file that I use is a simple 4 page inDesign document. Each page contains a single edge to edge rectangle specifying 100% fill of one of the CMYK colors. The challenge I was running into was that even though the document specified 100% yellow, it was printing with a bit of cyan and magenta mixed in. This was a real head scratcher since the other 3 colors were printing fine. Just the yellow that was mixing in colors.
After 2 hours on the phone with Xerox level 2 support I finally figured out how to print what I’m after. It’s a simple two step process.
That’s it. Your document will now print 100% yellow when specified.
The only time I use these setting is when I’m printing these test CMYK sheets. It probably wouldn’t hurt anything if I made this our default color setting, but I’m wary of changing what’s working. Besides, we don’t use a lot of 100% yellow boxes anyway : )
