Printing to PDF causes jpegs to switch from CMYK to RGB

[BMBirdsong]

Help! I'm past deadline because of this. I have a file created in Corel Draw 8 that includes three CMYK jpegs, with resolutions of 300x300 each. One is 5.5" x 8.5", the others are 1x1.25". When I write the PDF, the resulting file appears to be okay to me, but when the PDF is pre-flighted for prepress, it reports the jpegs to be in RGB mode, and at too low a resolution to use. I have been over all the settings, and I don't see what is tripping me up. I've tried using the distiller, but no luck. Any help would put me back on schedule!

Thanks!

I use Acrobat 4 and I am sure 5 & 6 are similar, in the distiller job options there is a preset option for Press Optimized this will, amongst other things leave colour models unchanged and embed all fonts. I print directly to the distiller as it appears with my other printers on the list.

Brushman,

Thanks for your response. I'd already tried that, and it didn't work. After spending $39.50 for a support session, it turns out Corel Draw 8's ability to produce PDF's just sucks. Answer: Upgrade to Draw 11. After downloading the trial version, it seemed to work.

Well, Draw 8 is not known to be a great version - you could have purchased the full version of Acrobat to make your PDF ... or purchased any of the PDF clones, like Jaws and made your PDFs through them.

Javabear:

No go. I have the full version of Acrobat 4. But the distiller requires a postscript file to work with. Turns out Corel Draw 8 doesn't do that very well either.

Um, no, it doesn't require "a postscript file." When you install Acrobat it sets itself up as a printer - just print directly to Distiller out of Draw. I've never had a problem doing that. You can do that out of any program on your computer (that you can print out of) if you installed Acrobat correctly.

As per my previous post I print directly to the Distiller, this way you can use all of the pre-press functions that Draw provides ie imposition/separation etc. I know in V10 there is an option of how you print bitmaps ie cmyk - RGB - greyscale but I'm not familiar with with V8.

Everyone:

THanks for the help. I appreciate it. The thing that finally worked was downloading version 11. Corel 8's interface with the distiller didn't have the right controlls, and according to Corel support, it defaults to rgb output. They've cleaned this up since. It looks like I need to upgrade.

That would be true if you were using the "publish to PDF" features within Draw. If you print directly to Distiller *and* you've gone into Distiller separately and properly setup your job options it should have worked.
