I am having difficulty getting good graphics resolution when I PDF from Word 2007 into Adobe Acrobat 8 Standard. My graphics look perfectly sharp in Word at any size, but become "pixelated" when I PDF them. I have tried using the Acrobat "High Quality Print" setting in Word, but this only results in minimal improvement.
I discovered that the quality of the graphic in Acrobat depends on the format of the graphic file I inserted in Word. PNG and GIF graphics PDF poorly, and JPEG graphics PDF better. My problem is that I need a transparent background for our company logo, and the JPEG format apparently doesn't support that.
I never had any trouble PDFing graphics in earlier versions of Word, so I'm not sure why this should suddenly be a problem.
