Acrobat (and Reader) do no such thing. HOWEVER, depending on your settings we MAY use color management to convert from the source profile/working space to the destination profile of your printing device - such a conversion may lead to better device colors. This is especially true when working with CMYK-based Postscript devices where we will convert to CMYK as part of the PS generation.

Printing some articles of online magazines using acrobat reader leads to good-looking text on color laser printers whereas printing the same PDF files using xpdf, gv or anything else yields poor text quality, as the text is printed using colors(*). Digging a bit further it seems as if acroread does something like using a "luminescence threshold" below which the printed text is defined as black, even if it is not gray, but something like rgb 0.140993 0.121996 0.125002 Is doing the same feasible? And if yes, where is the right way to put it? Knowing where to start, I could try to create a patch. (*): It looks as if there is a halo around the letters of the text; it's not clear. Thanks a lot, Olaf _______________________________________________ poppler mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/poppler _______________________________________________ poppler mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/poppler
