Why can't I just export a PDFX file directly from my layout program?

PDFX files exported directly from a layout program such as InDesign or Quark can have unexpected results. While the PDFX format is designed to greatly reduce the chance of unexpected errors when outputting a file, issues can arise. Instead by first creating a PostScript (PS) file, you are further reducing the chance of something going wrong. When you produce a PS file, you are printing the file to disk which locks down the print process.

Is a PS file the same as an EPS file?

No. An EPS (encapsulated PostScript) file contains only data which describes the document and graphic elements within it. A PS (PostScript) file contains the same data but also includes information describing how it should be printed.

I need to replace a file that was already submitted because I made a minor text correction. Do I have to create a new proof?

Yes. Any time a change is made to a digital file it is in a sense a new file. To ensure the new file prints exactly the way you'd expect it to we'll need a new proof.

Can I send Communication Arts my native file with fonts and have you create the PDF/X?

No.

What are the most common reasons a file is rejected?

The most common file problems are:
• Trim and Bleed marks not incorporated in the layout itself
• Trim and bleed size not correct
• Unintended Spot Colors
• Truetype fonts / Missing fonts
