Removing a knock-out

[S***@adobeforums.com]

I'm not sure if this is an InDesign question or an Illustrator question or an Acrobat question, so please forgive me if I'm posting it in the wrong forum.

I have a CMYK PDF that I'm creating in Illustrator CS1 and placing in an InDesign CS2 document. The InDesign document is then converted to a PDF/X-1a compatible PDF.

In the original PDF, I have black text over a colored background. When I look at separations in Acrobat 7 eliminating black, there's a white knockout where the black text would otherwise be. IOW, the text shows as paper color through the CMY combination.

This causes problems at the printer end, since it means they have to try to get the black text in registration, and the type size is too small for that.

What I'd like to do is tell InDesign or Illustrator to lay down the CMY and overlay that with black. Is that possible - and if so, how?

TIA.

Open the Illy PDF in Acrobat Pro and check the seps there. Is black
overprinting? What does the sep preview in ID show when you kill the black?

I know you have have no plan to export the final PDF but do it anyway
and check the result.

Some other things to check:

In Illy, make sure that the appearance of black preference is set to
output all blacks accurately.

Make sure that the attribute of the text is set to overprint.

When printing to Adobe PDF, make sure that distiller is honoring overprints.

Scratch that. It's a CS2 pref.
