Reply To: PDf files in inDesign

I would check to see if the CMYK values are correct in the PDF. Just because something looks a certain way on screen doesn’t mean that it will look that way in print. For example, if the client made a PDF in word based on RGB colors, then the printer may have converted that to CMYK using one method that kept it yellowing. However, if you converted it to CMYK in InDesign (when you made your PDF, for example), then that same RGB could have changed to a different CMYK (perhaps with more cyan, making it greenish).
