There was only one instance, or one particular case where rendering had some artifacts. It had happened on four pages out of 36 page brochure and we couldn't figure it out. No rime and reason since mostly the same graphics were used throughout the brochure.
Heidelberg told us specific setting in Indesign that reduced these artifacts, but they were still happening so they escalated it.
It had something to do with very specific, complex way piece was designed in Indesign.
Image was placed in box, than another box was created on top of that with gradients that were overlapping each other.
When previewing PDF, it looked ok, when render one side would have artifacts, like a very thick trap or overprint, which was not there.
When you render with CPSI, it rendered correctly, just like PDF preview, which was our workaround to get the job out.
They are looking into it.
Yes, we are happy with APPE otherwise, this was the only instance in many jobs.
I think we got little bit spoiled, since when we had Brisque, we were running on a daily basis into unexplainable things that Creo.Scitex/Kodak could never give us proper answer and we just continued using it and writing it off.
In this economy where every dollar count, that wouldn't fly anymore.
