Common Controller
Job submission order
Job submission order can impact performance. It is suggested
that a job with many pages to be RIPped and a large number of
copies should be submitted at the end of the day if possible. With
the printer paused, the job can then RIP over night. The job will
then start printing the beginning of the next day and while it is
printing, the DocuSP can process a complex/difficult job that
takes a long time to RIP. As long as the previous job is still
printing when the next job finishes RIPping, the DocuSP can RIP
still another job to get even further ahead. In this way, the print
engine itself will never be idle waiting for a hard job to finish RIP.
Job RIP Hints
If using the default media/color settings that are pre-loaded on
the controller, the DocuSP can use built in color space
transformations to accelerate RIP performance. If you do any of
the following, the color space transformation will probably take
more time and the RIP will be slower:
•
Define own media
•
Include input or output ICC color profiles in the PDL file
•
Change any of the system color settings (i.e. saturation,
lightness, color adjustments for C,M,Y or K, emulation mode,
etc.)
NOTE:
In general, RGB and LAB color space transformations
are slower than CMYK transformations. If the input images of a
job can be created in CMYK color space then the DocuSP will be
able to process the job more efficiently.
Variable data
Variable data job construction is also an important driver of RIP
performance. Jobs that are constructed with a single underlay or
background plane and a small number of variable text or image
overlays will run very efficiently. If the same job is constructed
with the underlay constructed from several distinct objects which
the DocuSP is asked to compose on the fly, then the job will not
be able to take advantage of the DocuSP variable data
performance enhancement. In that case, the job may RIP
significantly shower than the more efficiently constructed job.
