A catalogue set up in InDesign looks fine on screen, it looks fine on laser prints and looks fine on pdfs. We've even run GMG print proofs and everything looks fine. However, at print stage any type which is over a transparent picture box has 'spread', making it look like a bolder weight of font. The text in question is four colour grey - this is insisted on by our client and can't change to solid black (100K).
Our printer has resolved the problem by making adjustments to the final pdfs we supplied but I wan't to correct this in InDesign so we have control over our artwork and files sent to print. There seem to be no trapping options in InDesign to fix this. Or any other way to fix it within InDesign for that matter.
Has anyone come across this problem and found a solution for it?
I've seen other forums that suggest InDesign ligatures causing the problem, or printer rips. But this can't be the case in this instance.
Are you sure the text is ABOVE the transparency?
Hi Bob. Yes, text is definitely above (in a layer above). That was one of the first things we checked.
If it looks good iin the PDF and right up to the print stage, I think it's a good bet that it IS the printer's RIP that is causing the problem, unless of course you are sending him a different PDF. The bilding effect is almost certainly a flatening problem, and if the RIP is doing the flattening, it's pretty hard to believe it isn't the cause.
