No, its a visible option and it works, but the colors are totally fubared. > If yes then we > have a major problem as printing shops often require CMYK to > properly render colours on the presses.

It supports the mode, but the mode is broken. In the horizontal bars, the color is just barely discernable at the right ends of the very dark bars, with only the green bar having any obvious color. I get exactly the same results from the KCMY mode, except the butterfly in the upper right corner is replaced with a warped geometric pattern of small squares that fill where the butterfy would normally be. > >If you haven't already registered, do the following: > > 1.

Unforch, how I would file the examples would be by scans from my epson 1250u, and they're huge multimegabyte things at any usable resolution. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
