On my LinkedIn profile page (under the Summary), uploaded pdfs look blurry. Individually, when selected, the quality is fine. Files are created in InDesign CS5 using Adobe preset "High Quality Print", following recommendation by Adobe. LinkedIn tech support says the issue is that the pdfs are not of high quality but is not specific on what individual settings should be when creating pdfs. Posts on LinkedIn help section note that others have had the same problem, but there are no corresponding answers. Can anyone help? Thank you.
