About JDF files
A Job Definition Format (JDF) file created in Acrobat describes the creative intent of a
product, or print job. These specifications can be used in a production environment to
produce the final printed piece. JDF files include such data as media and ink requirements,
production quantities, customer information, and product descriptions. The JDF file also
includes references to files that contain pages and describes how those pages should be
ordered to make the product. In addition, the JDF file may include certain information
necessary for the creation of Adobe PDF files appropriate for the production process,
including PDF conversion settings and preflight profiles.
A JDF file can evolve over time as more information is gathered about the job, or it can be
completed as the job is submitted for print production. The format is flexible enough to
start as a high-level definition describing only a rough outline of a product, and be
modified with more concrete details about the product. Or, it can be completely created in
one session.
The JDF file and associated PDF files travel together as part of the JDF workflow, from
JDF device to JDF device. When the JDF file is submitted to production, the information
it contains is used to define the processes for print production.
