What is JDF?

Question: What is JDF?

Although not supported in all desktop publishing software, Adobe Creative Suite 2 and above and QuarkXPress 7 and above support this data interchange method. Some print shops implement JDF into their workflow using JDF-enabled equipment and software even though files from the client may not arrive with JDF job tickets initially.

Answer: JDF or Job Definition Format, is an XML-based file format for an electronic job ticket. A JDF file would contain all the job information that might normally be included on a written form sent in with a print job or communicated by email, phone, or other means.

The JDF job ticket travels with a file from creation through preflight, prepress, and production insuring that the proper handling takes place at each stage and helps eliminate errors and miscommunication. JDF information embedded in a file might include instructions as to document creator, client contact data, included fonts and images and additional files, paper size, color profiles, types of proofs requested, imposition, RIP settings,paper stock, and folding instructions as well as who to notifiy upon job completion and where to send the completed print job.

A JDF file can be generated and added to at various stages of production when using JDF-enabled products. Information relevant to the handling of the file can be added to the JDF job ticket at any stage such as documenting alterations and adding job completion date/time after printing and finishing.
