We're having an issue lately with a lot of black prints coming out with a bit of a greenish hue. The latest is on a piece of customer supplied art, and the background which is supposed to be black (r-0 g-0 b-0, c:75% M:68% Y:67% K:90% ) in photoshop isnt printing completely black. I've tried desaturating it and its still having the same effect. Any suggestions so I dont have to reprint this many times? Thanks

you can change the black color part to print 100 % black in illy if your using that, not sure if you can in ps, but we've done this in illy before.

rich black for me is 30/30/30/100 -- my RIP always converts RGB 0/0/0 black greenish...

why is the black only 90%?
what's causing the greenish tinge is the yellow ink interacting with the black (that is not 100%)...
either reduce your yellow level a bit in the black formula or increase the K to 100% or both
we have good success with 30-30-30-100 (CMYK)
(100%Y + 30%K == green) (and yes, its not a real pretty green)

You can try...
..to change the settings in Versa Works. At the Color Management Place, in "Quality" window, try to modify from what are you printing with to "Maximum Impact" or "Custom", and if you change to "Custom", press the Proprieties Button there and mark "Preserve Primary Colors" and "Embed ICC Profiles".
Just try it....and you will see if it's better then before.
