Ok, here's the scenario!
I have a flyer, created in InDesign. I have drawn a grey curve (in InDesign) which goes at the top of each page.
I import a transparent logo in PSD format, and place it on top of the grey curve.
In InDesign and when I PDF it, it looks fine (at any zoom level).
However when I print it, there is a slight outline around the transparent logo and it has a slightly different shade of grey as its background (it stands out from the curve).
Does anyone know why this could be? I also tried importing the logo with the same grey background as in InDesign but the same problem occurs.
Any help appreciated!
Thanks Peter! I followed the steps and printing from InDesign is now fine! (Although I couldn't select Composite CMYK for some reason, only RGB).
Is there any way I can save this setting to the PDF? As I assume the printers will require the file to be sent in PDF format.
If you can't select composite CMYK it means your printer isn't postscript, or you aren't using the postscript driver option if one is available.
Since this is a printer-related function, not a property of the file itself, you don't want to do anything to your pdf to compensate. That's the printer's job, if necessary, when he processes your PDF.
