Why a difference between picture quality in InDesign and PDF output

Jan 27, 2013 10:37 PM

We are comparing the CS5 pdf output of our book with the ID version. The images are MUCH clearer and the colors are better when we view a page inside of ID side by side with the PDF. The pictures actually look blurry in the PDF, even though we are outputting at 600dpi.When we export to PDF in cs6, the clarity is much better but the color is still a little off. Is this normal?

    Where are you viewing the PDF? In AcrobatPro XI the two PDFs appear to be identical both in resolution and color.

     

    The color is all device CMYK (no profiles), so the preview of the CMYK color will depend on the reader application's color management capabilities or settings. Try exporting using either PDF/X-4 or PDF/X-1a if you want to force everything to CMYK.

    I'm not seeing any color differences here, either. I'm on Acrobat 9.

     

    Are your color settings the same in both versions of ID? Are you using the same simulation profile when using output preview for both files in Acrobat?

    The X-1a exporting from CS5 looks much better than the normal output, and better than the CS6 output. What would cause that?

     

    If you export a CMYK PDF with no profiles and open it in AcrobatPro, Acrobat's Color Management's Working CMYK space handles the preview. So here's the difference between two very different profiles Fogra Coated and SNAP Newsprint:

    When you export PDF/X-1a an output intent profile is included (usually your document's CMYK profile) and that is used in Acrobat for previewing CMYK instead of the current CMYK working space.
