NOTE: Only one decomposer runs for each context,
regardless of the number of queues that exist. If you set up
five protected queues, all five queues funnel jobs to one
protected decomposer. The same occurs with unprotected
queues. A command sent to one unprotected queue is
directed to the unprotected decomposer. Because all
unprotected queues feed into the same unprotected
decomposer, the command persists across all unprotected
queues and affects all jobs sent to those unprotected
queues.
8. Select a Variable Data option:
• Enable Caching
• Disable Caching
More Information...
Disabling the VIPP cache may be necessary when the user
consistently has difficulty balancing OutQ size. OutQ size is
defined as the amount of disk space set aside for the job after
RIP and prior to printing; the amount of disk space available
for OutQ varies based on platform.
The System Administrator will have the capability to define
disk space for caching that comprises 0% to 30% of the OutQ.
The GUI provides a disk space indicator.
It is important to consider appropriate cache sizes, because
the OutQ space is used for long jobs as well as for the new
variable cache. Therefore, removal of too much disk for cache
will also reduce your OutQ size and potentially force long job
chunking mode (in which long jobs are spooled to print in
chunks); this negatively impacts performance. Thus, there is a
potential trade-off between the competing disk uses.
Management and removal of cached resources may be
required for an account who would like runs with large,
persistent VIPP caches, or whose jobs routinely saturate the
OutQ.
9. Select an After Job Completion option:
• Delete Cached Objects:
• Retain Cached Objects
• PDL Specified
10. Under OPI (Open PrePress Interface) Substitution, select
[Substitute Images] to enable the substitution of images.

unavailable.
Select an Open PrePress Interface Substitution option. Select
[Do Not PreScan], [PreScan], or [PreScan & Gather]. The
options are described below:
