You can create new JDF job definitions in a variety of ways using the JDF Job Definitions dialog box. Each resulting JDF file can be edited and used in a production environment. Commercial printers who routinely print certain types of jobs may find it useful to create several JDF files that match these job types, and use them as templates. Using a template saves time and avoids costly mistakes, but may not be appropriate for every job. Before you construct a new job definition from scratch, review existing job definitions for ones that achieve results similar to what you want.
