cups, pdf and opacity problems
 
Hi all,

I have a pdf with a semi-opaque watermark. In evince the object is fully opaque. In kpdf the object views semi-transparent but prints fully opaque. In Adobe Reader it prints and views correctly semi-transparent. Printing directly from the command line it prints fully opaque. I think (in my ignorance) it has to do with PostScript Levels ???The problem with Adobe Reader is that I can't print multiple copies!!!.

So, I'd really like to understand what's wrong, but most importantly I'd like to have a cli option to print multiple copies of a bunch of pdfs.

Thanks for any ideas,

Brian

It seems that only Adobe's pdf-ps filter handles the transparency correctly. Has anyone else had this problem?

Anyway, if anyone else wants to go the command line way, what worked for me was "acroread -toPostScript -landscape *.pdf ps_dir/" which creates PostScript files which I can print with lp, so I can easily automate what I'm doing.

I'd still like to understand why evince and kpdf fail.
