AuthorSubject: Grey Scale in CMYK file   [Go to Bottom of Page]
Jim Kahnweiler
Posted on Wed Nov 19, 2003 12:17 PM

I've created a color ad for newspaper reproduction. This ad is built entirely in Photoshop and linked to a Quark file for seperation and conversion to pdf for FTP transmission to the printer. It includes a grey scale photo that reproduces with a strong magenta cast. This cast is present in all color from the same printer. I correct for out of gammut while in RGB using soft proofing, convert to CMYK and redude Magenta about 8% to elimate the cast.

If I pull the curve for the grey scale image, I could introduce other colors. I thought if I could imbed the grey scale image on the black plate, instead of having Quark seperate it into CMYK, I could elimate all the color issues (except streaking from the press). Is there a method for virtual stripping?

Thanks.

Jim Kahnweiler
