Dov, I normally do agree with your statements on these lists, but this time I beleive you fail. <...any text or vector graphics, for which R=G=B (i.e., grayscale including pure black), yields grayscale PostScript.> Nope! Indeed, this might have been the intended behaviour, no doubt, but in cases where RGB should have been R=G=B it might not be so in the real world with GDI. Often GDI returns R<>G<>B for colours that were meant to be gray, and the setting you mention does NOT catch such 'gray', because the threshold for 'almost equal' doesn't catch it. Our CMYK PDF Creator does have a built-in (currently hard-coded - based on 276 test jobs from MS Word) threshold value and a built-in 'almost equal' operator that catch any to us known such 'gray', however. <... you cannot properly print RGB PDF. Bull! Using the "Advanced" function of Acrobat's print menu ...> How would you configure a native Acrobat 6.0 Pro to save a proper PDF for in-RIP separation on a PDF RIP the way you mention?

This makes sure that any text or vector graphics, for which R=G=B (i.e., grayscale including pure black), yields grayscale PostScript. These options are automatically set correctly for the "Adobe PDF" printer instance for Acrobat 6 under Windows. - Dov Another approach is just leave the PDF file in RGB. Contrary to bubbameisers and other urban legends, there is absolutely nothing wrong with RGB, but rather with prepress service (alleged) professionals who claim that you cannot properly print RGB PDF. Bull! Using the "Advanced" function of Acrobat's print menu, one can EASILY map Microsoft's flavour of RGB (actually normally sRGB by default) to SWOP CMYK. It is the same exact code used in Photoshop or any other Adobe tools for conversion upstream. - Dov At 7/23/2003 07:10 AM, Larry wrote: "Does anyone knows how to create a pre-press ready PDF using Microsoft Word on a Windows PC ? My main concern is that the PDFs I create from Word have RGB images and not CMYK ones. I am using Acrobat 6." It's a RGB world in MS products. A couple of choices. Create your PDF from word in the normal fashion, which of course will be RGB, then convert to CMYK via PittStop or QBT. OR, place the Word file into InDesign, and use InDesign's PDF export function with CMYK selected under color. ID will do the conversion. OR, open the RGB PDF with Illustrator 9 or 10, change document color space to CMYK, select all and convert to CMYK. Resave.
