Yeah, that's it. I ended up hacking the PDF to convert all RGB to grayscale, but even if the result was the original without colors (what I wanted), converting it to ghostscript made some text unreadable (white on white), so it was clearly not a good idea to trust it to look the same everywhere. I gave up and used the color version. > This is one method to do this, but it needs Acrobat 8 Professional: > http://blog.gilbertconsulting.com/2007/05/convert-color-pdf-to-grayscale.html Thanks for the link. Although I don't have Acrobat, if I ever happen to get access to it I'll probably check that feature :-) -- Nuno J. Silva gopher://sdf-eu.org/1/users/njsg
