As term I use eps or pdf (also tried pdfcairo) as I want to include figures into pdflatex. I want to include the figures in a paper, so they should be neat. On screen the resultant graphics show strong artifacts, namely white or black lines along edges of "tiles". I found in some forums the hint that this are probably anti-aliasing artifacts of the ps-viewer (gv 3.6.5 under cygwin) or the pdf-viewer (tried acrobat reader 9.3, foxit 3.2, sumatra 1.8). Using gv with - noantialias nearly removes the artifacts on screen, although I can still make out the white lines. They are also present on the printout (on a Kyocera PCL XL with 600 dpi). With pdf output things are even worse.
