Symptoms

A PDF that contains an exported EPS from Acrobat 4 does not show the EPS: the area where the EPS should appear is blank.

Note: the problem also occurs outside of Prinergy; the Allegro RIP does not show the image either.

Other info:

I made an interesting test with this document. I distilled the Acro4 EPS directly, and it appears as expected (I can see the image just fine). So the EPS itself is ok. I suspect this is related to the OPI engine in the Normalizer, and its interaction with the EPS code generated from Acrobat 4. I doubt very much that the problem is in Acrobat 4.
