In the Prinect Pressroom Manager/Prinect Integration Manager, the job can be generated using the JDF/JMF file (from MIS) or the PPF/CIP3 file (from the prepress system), depending on which of the two files is processed first and how the Prinect workflow was configured. It is vital, however, that the job is always generated by the MIS using the JDF/JMF file and the PPF/CIP3 file is then assigned to the corresponding job. A job generated via the PPF/CIP3 file cannot be assigned to a JDF/JMF file. It must thus always be ensured that the JDF/JMF file is processed before the PPF/CIP3 file in the Prinect Pressroom Manager/Prinect Integration Manager.
The procedure in the JDF-PPF workflow is as follows:
•The Management Information System (for example: Prinect Prinance) delivers a JDF/JMF file.
•A new job is created from the JDF/JMF file in the Prinect Pressroom Manager/Prinect Integration Manager.
•The prepress system delivers one or more PPF/CIP3 files.
•Based on the job number, the PPF/CIP3 files of the prepress system are automatically assigned to the job that has already been created (from the JDF file/JMF message).
In practice, however, it can occur that the prepress system supplies PPF/CIP3 files and the job (JDF file/JMF message) is generated only later by the Management Information System, for example, or the prepress system delivers PPF/CIP3 files in which the job number does not correspond with the job number in the JDF/JMF file from the Management Information System.
Furthermore, the system behavior always depends on the job number and the sheet designation, which are both integrated in the JDF/JMF file and in the PPF/CIP3 file. Automatic execution (automatically merging JDF/JMF file and the PPF/CIP3 file) can only work if the job number in the JDF/JMF file and the job number in the PPF/CIP3 file are identical. If this is not the case, manual intervention is necessary. You will find a detailed description of how to intervene manually in the section Working in the "Job Combiner".
So that you can understand the effects better, we have listed some practical cases in the section System behavior.
