Imagemagick, gimp, photoprint and I guess everything else in the free
software world use ghostscript for the rasterizing process. I
currently run gs (ghostscript directly) since I feel I have more
control this way. I think it is especially important with cinepaint,
I have of course learned this the hard way :-)
Here are some command you may find useful, and I think it's a good
Idea to add something like this to the printing section in
Scenarios.html too.
convert a RGB ps (or eps) to 16bit png
/usr/bin/gs -sDEVICE=png48 -dNOPAUSE -r300
-sOutputFile=PrinterA%d.png PrinterA.ps -c quit
Convert a CMYK ps(or eps) to 8bit tif
/usr/bin/gs -dNOPAUSE -sDEVICE=tiff32nc
-sProcessColorModel=DeviceCMYK -sOutputFile=PrinterB%d.tif
PrinterB.ps -c quit
and as usual the chossen devices over may require a ghostscript
upgrade. If you have an older choose psdcmyk(pdf file) for cmyk and
tiff24nc for rgb charts, as sDEVICE options.
