PDF saved from Illustrator converts placed image colors

[posineg]

Greetings,

I have a file that when saved to PDF, 1-2% tone is created in areas that should not have any tone.
For example, a orange fruit is void of Cyan color in the EPS file created in Photoshop. When the EPS is placed in the Illustrator file and saved as a PDF, there is now a "scum Dot" of Cyan throughout the area of the placed image.

This is a new issue, since the preveious versions of Illustrator did not have this issue.

Any ideas?

I have:

saved various encoding types of EPS(non-JPG)

Saved out various PDF version, trying to have PDFX4.

Adjusted color setting to ignore or maintain color profiles.

Assigned/removed document profile

I have found that the Normalized PDF from Esko saves fine but I cannot embed a profile for viewing using Esko.

Thank you.

Why are you saving a PS file as .eps?

[posineg]

There are RIPs still in use by many printers that cannot handle a layered PS file. EPS is a standard that can be handled by many/all RIPs.

But if you are then saving out to pdf isn't that rationale moot? (I rarely use eps, I'm asking out of curiosity).

The final files might be outlined text Illustrator files. The "soft" proof is a PDFX file with embeded profile.

It is easier to just format all placed images as EPS than to pick/choose which files might be Outlined AI or PDF and format or not.

We get a large amount of printers and each has thier own requirment. Most will not except placed PSD files.

So you send PDF to the print house, not open files?

Then why does the print house even care what image format you place into your layout file?

[posineg]

The PDFs are "soft proofs", to be evaluated for trap, fit, color accuracey, sizing...

After approval, Color accurate prints are made for press-run comparison and final files are made.

Depending on the printer, the final files could be outline AI file that include placed images.

Many RIPs and imposition software will not accept PSD files, especially layered effects and transparencies due to the RIPS not translating the image like Photoshop would. EPS files are flattened images with little error.

I do not argue with the printer who requires non-PSD placed images. Any down time on the press is money out of someones pocket and I do not want to cover that cost.

Maybe someone in the color management forum can help you with that workflow.

Please post your color management settings there and the options you choose  when exporting the EPS and also when placing it in Illustrator and when exporting the PDF.
