Acrobat 4 displays overprinted images as knockouts


Product

  Prinergy 1.1; Prinergy Connect 2.0

Platform

 

Server: Dell or Data General all; Client: PC or Macintosh

Operating system

 

Server: Windows NT or 2000; Client: Windows or Macintosh


Error

 


Symptoms

 

Objects set to overprint in the PDF are displayed as if they are knockout images.

The PDF file could be from any source that uses overprints to paint the page.

These could include:

- a page which has been designed to use overprints

- a PDF 1.4 page that has been flattened to PDF 1.3

- a PDF page from the CEPS JTP or PDF2Go


Cause

  Adobe Acrobat does not display overprinting at all.

For example, if you have a yellow triangle set to overprint on top of an image, you should still see the C,M,K data from the image.

Acrobat displays this as if the yellow triangle was knocking out the image.


Solution

 

A. Use the Separation Viewer plug-in, or generate VPS proofs, to confirm overprinting.

B. Or use the Overprint Preview feature in Acrobat 5.

Permanent fix:
