It appears that the world of self publishing is in cahoots with Adobe. Most of the print-on-demand services I've looked at require files to be created in Adobe Acrobat. Lightning Source is specific, requiring files to be PDF/X-1a:2001 or PDF/X-3:2002 compliant. (Adobe Acrobat Pro versions 6 or 7 and above respectively).
Of course there is no Adobe Acrobat for Linux. In my research I found PDF Studio, which comes in a Linux version, but the information isn't detailed in regards to this. I'm not going to spend money if it can't meet my needs, but it's a heck of a lot cheaper than Adobe Professional.
Has anyone navigated the self publishing path in Linux (preferable Ubuntu)? I do have a Windows partition, but really don't like going there. Any suggestions?
