I read that my printer wants to use PDF/X-1a:2001 for best printing results.
This is a little not LyX specific, but .. How can you tell what PDF setting is in use? For example, one of my books is: tx:reed$ pdfinfo book.pdf Creator: TeX Producer: pdfeTeX-1.21a CreationDate: Thu Dec 20 11:57:04 2007 Tagged: no Pages: 595 Encrypted: no Page size: 535.68 x 696.959 pts File size: 4034185 bytes Optimized: no PDF version: 1.4 I think version 1.4 is newer, but I don't know. What tool can I use to check for "PDF/X-1a:2001"? By the way, my producer (pdfeTeX-1.21a) is from teTeX-bin-3.0nb14 (pkgsrc package). Any suggestions on tweaking that to create correct PDF? Jeremy C.
