The customer reports and I've verified that the attached PDF file is missing all of the vertical lines when ripped by Ghostscript as compared to Acrobat Pro 9. The command line I'm using: bin/gs -sDEVICE=tiff24nc -r600 -o test.tif ./Nordwest_d.pdf

Created attachment 5194 [details] dflt-stroke-after-fill.pdf - simplified sample file The sample file is rather simple. The file selects a fill color, fills an object, and strokes a line with default color. q 1 1 1 rg 0 0 8 8 re f 0.75 w 2 J 0 0 m 0 8 l S Q Ghostscript appears to use the fill color for stroking. This bug exists on all versions of Ghostscript. It should be quite easy to fix.
Set default color and colorspace for colored pattern stream that relies on default values; keep the color unset as required for uncolored pattern. The following patch has been committed as a rev. 9850. http://ghostscript.com/pipermail/gs-cvs/2009-July/009547.html Regression testing shows no differences. The simplified file dflt-stroke-after-fill.pdf has been added to the public test suite by the rev. 9851.
