Reply To: Rich Black over Rich Black

Just tested the PDF and the separations looked fine on my screen. The frame you are speaking of is likely to be the frame that contained the eps logo in InDesign. Has your printer offered an explanation as to how this may have happened, and if so, what was the explanation? Does the printer have a procedure in place for handling non-conformance issues like this?

Was this the only page that this happened on or was this throughout the document?

I have occasionally seen results like this but NOT on an offset print, but digital colour copies… where the black was 100K only and the graphic above had an unexpected effect on it that wasn’t visible. In instances like this, the Fiery RIP would make the 100K areas print so dense it was closer to registration colour than black; but anything that was where the graphic frame was would just be matt and dull. Ultimately I don’t think this is what is happening in this instance.
