Artifacts appear in the CT area of a CT/LW page


Product

Platform

 

Operating system

 


Error

 


Symptoms

 

A hairline artifact appears in the CT area of a CT/LW page.


Cause

  The boundaries between CT strips should be able to be represented exactly in points. If the CT resolution is an odd number, rounding errors can cause gaps in the CT.

Solution

 

Set the CT resolution to one of the following:

300, 320, 360, 375, 400, 450, 480, 500, 576, 600, 720, 750, 800

- You can do this at the RIP (Brisque).

- Or, you can do this at the Optimize stage (select a CT resolution from the list above).

- Or, you can also do this in the registry on the Prinergy server:

HKEY_LOCAL_MACHINE\SOFTWARE\Creo\Araxi\2.0.X.BLDXXX\Default\CEPJ\CEPSJtpOnXXX

- Set CTResolution to the desired DPI (such as 300 in decimal) and set SubsampleCT = 1.

.

If you are using the CEPS JTP in Prinergy 2.0.7, or PDF2Go in Brisque 4.0, this should not be necessary (should not get hairline artifacts in CT area.)

Permanent fix: Prinergy 2.0
