The customer reports and I've verified that converting the attached EPS file to PDF via -sDEVICE=pdfwrite produces a PDF file that is rendered differently in Ghostscript than a file converted from EPS to PDF via Distiller . Specifically there is an offset in the text interior vs. the outline. I've attached the original EPS file, the PDF generated by Acrobat Distiller, and a screenshot showing the output from Ghostscript. The command line I used to generate the PDF: bin/gs -sDEVICE=pdfwrite -sOutputFile=pipo_ghostscript.pdf ./pipo.eps And to view the PDFs: bin/gs -r1000 ./pipo_ghostscript.pdf bin/gs -r1000 ./pipo_distiller.pdf The customer reported this with 8.57, but head (r8085) output is identical.

The problem is seen at 300, 600 and 720 dpi from the original EPS. Since the pdfwrite device defaults to 720 dpi, it is _NOT_ a PDF problem, but something else (font or graphics library precision?)
Passing to Ken since he handles pdfwrite from now.
The bug Bug 688007 "cjk bold fonts printed many times" shows a similar problem, which may be addressed as an idiom recognition.
Patch http://ghostscript.com/pipermail/gs-cvs/2007-October/007845.html resolves the issue.
