Yeah, that's it. I ended up hacking the PDF to convert all RGB to |
19 |
grayscale, but even if the result was the original without colors (what |
20 |
I wanted), converting it to ghostscript made some text unreadable (white |
21 |
on white), so it was clearly not a good idea to trust it to look the |
22 |
same everywhere. |

Thanks for the link. Although I don't have Acrobat, if I ever happen to |
30 |
get access to it I'll probably check that feature :-) |
