    This has been an issue for many years, in my experience. When printing a drop shadow or a glow with a solid color (especially black) in the background, I get a box around the image that prints in the background color but darker. Is there a foolproof way to eliminate this box that prints? I've tried all kinds of tricks from flattening the transparency with all the settings available to dropping a box with no color on top and using the multiply transparency setting in Illustrator. Does ANYONE have a definite solution to this issue?

    That's an issue on many machines (Xerox, Konica etc). even on a Creo...

    Rasterizing the image always fixes the issue for us. Sometimes importing the image with a drop shadow as a PNG (with transparency) will help.
    I'm not quite sure why this happens. It never seems to occur if we typeset in house, only with customer EPS files , etc

    Part of the problem is caused by (1) the way the application is passing the information to the postscript interpreter and (2) the way Acrobat is generating the PDF. There are differences even within the different Adobe CS apps. Export a PDF with gradient-tints from Indesign and one from Illustrator nd you'll see different results. Indesign does a better job. Also, printing directly to the RIP will work better than exporting a PDf and then importing the RIP. If you must export a PDF, use PDFx4, it has better support for this type of thing. If youre using Fiery and all else fails, turn "Composite Overprint" on.
