just wondering if we're going to have any "joy" using our new harlequin rip (version 7) to convert rgb pictures to cmyk pictures. I'm a little scared because our old Apogee system did a terrible job (maybe not setup right) so we did everything at the desktop in Photoshop. Well we can't do that now because of the volume of pictures so we're hoping the rip will do as good of a job as photoshop with the rgb-cmyk coverstion set to U.S. prepress sheetfed coated (or whatever).

I know it's possible as long as it is setup correctly. We let Prinergy convert everything.

i think so too but we haven't even got the rip yet, everyone is nervous about the labor involved in converting thousands of rgb's to cmyk properly but I've stuck my neck out saying we could do it at the rip.

Here are the settings we use...

Couldn't you just set up a batch conversion in PS?

 I wrote a lil photoshop batch years ago for a friend who does gang run 4/4 cards and crap jobs, the batch does [everything] to 300dpi cmyk tiff. That probably still is his default workflow.

I learned that trick on Desktop Publishing Forums.

So,  :drunk3: i send the job to the rip with live transparecy (v 1.7 or whatever) and it craps out with a memory error.

If it's the latest/new version of HQ, I imagine it would be able to do that properly. Big hole if it can't.

Just looking over at Xitron's site... which one you getting? Navigator RIP? Are you going APPE? leaving PostScript behind? Hope so, for your sake.  :undecided:
They're talking PostScrip L3 there.

Just because that's the rip that came with the used SCREEN platesetter, no good reason as far as I know
