Hello, Indeed Acrobat 5.x is insufficient to handle softproofing and using profiles and Spotcolors the right way. You absolutely have to use Acrobat 6.x(+) to handle all these colorspaces and profiles the right way, and do a softproof and a correct overprinting view. All of that is important to examine a PDF regarding it's color and overprinting state. What I found about PDF/X-3 on http://www.pdf-x.com/pdfx_123_1.php is: it's a device independant container, which allows to handle all kinds of colorspaces if they are based on icc profiles. It's a superset of pdf/x-1a. Transparency must be flattened (that means isn't allowed) JBIG-2 compression and Encryption isn't allowed. All fonts and images must be embedded. The file must be identified as trapped or not trapped MediaBox and TrimBox or ArtBox must be defined; BleedBox is optional The output intent* must be specified either by stating a Characterized Printing Condition or identifying an ICC output profile * The output intent identifies the press condition the file is prepared for, such as type of press, and inks and paper that will be used.
