Well, after a little bit of googling, it looks like there was a rather simple solution. Since ps2pdf14 and epstopdf were just sending some pre-defined parameters to ghost script, it is possible to setup the gs environment, and then call epstopdf: export GS_OPTIONS=-dPDFSETTINGS=/prepress epstopdf --nocompress file.eps This will produce a PDF of the correct page size, without JPEG compression on embedded images! Just for the record, this allows one to create a poster in something like Inkscape (http://www.inkscape.org/), an opensource page layout program, and then save the file as an EPS. Unfortunately this EPS file is not easily sent to a printer (tried opening it in Illustrator 10, and there were numerous propblems in terms of printable area, etc.), thus the above method will create a JPEG compression-less PDF which can easily be printed from a PDF viewer.
