Course: Graphic Imaging Technology II (11154-II) > Section: Working with the Portable Document Format (PDF)

Distinction should emphasize the following:

- PDF/X-1a and PDF/X-3 are two types of PDF/X, which is a subset of the PDF international standard.
- PDF/X-1a is a type of PDF that restricts the content not directly serving the quality of print production output. In PDF/X-1, fonts must be embedded, and all images must be CMYK or spot colors.
- PDF/X-3 is a type of PDF similar to PDF/X-1a with relation to color management and ICC profiles embedded in the PDF.

Process/Skill Questions:

- When would it be important to save a file as a PDF/X-1a rather than a PDF?
- When would it be important to save a file as a PDF/X-3 rather than a PDF?
