Hallo,
I solved the problem yesterday.

Because of the questions "why / what" I will explain it a little.

I have 10 Postscript Color Printers, same Model, wich are working as a cluster. 
These Printers are getting load ballanced Jobs wich have just Text, Vector and 
Shade Content, so they can be ripped very fast inside the Printers Rip´s. Each 
Printer has it´s own Destination Cmyk Profile loaded as a CRD. All Printers get 
the same Thresholds for Screening with the Job.

So the problem I had was, that the internal Rip´s do not work correct with some 
Postscript Elements on TransferCurves. I solved this now by turning all 
TransferFunctions of and Profiled the 16 Bit Threshold´s before I stick them 
into the Printer´s Rip´s.


Regards

Manuela
