Leonard,
Thank you for your reply. I've posed to a number of different forums (including the Adobe Forums) and yours is the only reply I've had. I'm incredibly grateful for your time and expertise.
1. Platform: Windows XP, SP3
2. We cannot use hotfolders, and must use Acrobat, because we have a very large number of people (~300) submitting jobs to this workflow. Acrobat is established as our "print platform" and there is a lot of training and other related print processes that rely on it.
3. There is no transparency in our test file, which is attached.
4. Our PDF creation settings for export from InDesign were initially based on PDF/X-4, but do not conform to that standard explicitly.
- Version 1.5 (Acrobat 6)
- Create Acrobat Layers
- No Color Conversion
- Include All Profiles
- I have attached the .joboptions file
I'm very glad to see that Adobe is working on building consistent print behavior between all of the CS apps, but it seems as though we are seeing otherwise. Perhaps you can show us the error of our ways:
A) If we print the InDesign layout directly to the RIP from InDesign CS4, we see that the RGB vector is passed to the RIP as Adobe RGB (1998), that the CMYK vector is passed to the RIP as US Web Coated (SWOP), and that the color numbers remain intact. Needless to say, the print looks great. If we export a PDF from this layout and print it from Acrobat 7 Same As Source, we see the same behavior. Again, the print looks good. When we print the same file from Acrobat 9 Same As Source, we see that all of the colors are converted to CMYK, and that the color numbers are modified.
It is also worth noting that if we take the PDF exported from InDesign, and print it to file from both Acrobat 7 and Acrobat 9 Same As Source (files attached), we see the following behavior:
B) If the Acrobat 7 PS file is opened in Illustrator CS4, it rightly identifies that there are mixed color modes in the document.
C) If the Acrobat 9 PS file is opened in Illustrator CS4, it sees only RGB data.
A, B, and C all seem to indicate that Acrobat 7 and 9 differ in their treatment of Same As Source print submissions, and that Acrobat 7 is rightfully passing mixed color modes along, whereas Acrobat 9 seems to be doing some sort of conversion to a single color space. Further, it seems to suggest that Acrobat 9 and InDesign CS4 differ in their approach to printing the artwork.
What about Acrobat 9 specifically (or perhaps about our process) might cause for these discrepancies?
It may very well be that we have a critical misunderstanding of the underlying processes here, and if that is the case, I apologize. We really appreciate your patience and time.
Thank you again for your response and assistance.
Matt
