Howdy, Just compared a pdf produced using the Utopia font (via the fourier package) in Preview, Skim and TeXShop (with the hidden FixPreviewBlur preference set to YES --- thank you Yusuke Terada) and, to my eye TeXShop's Preview is the most true to the printed version. This on my 2011 21" iMac. Good Luck, Herb Schulz (herbs at wideopenwest dot com)
