Nice feature, indeed. It might save a preprocessing step. We preprocess with -dProcessDSCComments=false otherwise PDFs generated by external programs (OpenOffice, I'm looking at you) in combination with particular fonts might wreak havoc with the document they are included into. I don't know which downsides this might have, though. In our workflow this leads to more predictable results. Maybe someone with more insight of the PDF internals could judge if it makes sense to add this option. It looks like the presets are not hard-coded. What is the interface to change the presets (screen, ebook, prepress)? Marco
