Production and files
JDF
JDF, Job Definition Format, is a CIP4 format for describing print products, production processes and related job information.
What it means in packaging
A job ticket communicates structured production metadata to compatible workflow systems. It is separate from the artwork and structural files it may reference. A valid ticket alone does not establish that a particular press or MIS will execute it.
A practical example
A printer bundle can pair print files with a ticket that identifies job quantities and production resources.
What to check
Agree the receiving system’s supported version, fields and resource references, then test the handoff.
