Grayscale images will not overprint spot color backgrounds on Quark XPress page


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

 

***Applies to Prinergy Connect, Powerpack, Direct, Satellite, depending on installed configuration.***

In Quark XPress, a grayscale image set to overprint a spot color background appears to create a negative version of the image in the spot channel when refined to PDF.


Cause

  Quark XPress writes incorrect Postscript.

Solution

 

There are two solutions:

A. Place an overprinting box, filled with the spot color, on top of the grayscale image.( It will look wrong in Adobe Acrobat 4, because Acrobat 4 doesn't display overprinting objects correctly.)

B. Create a duotone of the image in Photoshop. Leave the black channel as it is, and fill the spot color channel with the desired background spot color tint.

Permanent fix:
