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 then starts printing at the beginning of the next day and while it is printing, the Xerox FreeFlow Print Server 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 RIPing, the Print Server can RIP still another job to get even further ahead. In this way, the print engine itself is never 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 Xerox FreeFlow Print Server process built in color space transformations to accelerate RIP performance. If you do any of the following, the color space transformation probably takes more time and the RIP is slower:

•Define own media

•Include input or output ICC color profiles in the PDL file

•Change any of the system color settings (that is, 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 Xerox FreeFlow Print Server are 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 run very efficiently. If the same job is constructed with the underlay constructed from several distinct objects which the Xerox FreeFlow Print Server is asked to compose on the fly, then the job is not able to take advantage of the Print Server variable data performance enhancement. In that case, the job may RIP significantly slower than the more efficiently constructed job.

For cases where the background/underlay of the variable data job is composed of 2 or 3 relatively static objects, it is suggested to have the application create each static combination of objects as a different underlay. This is more efficient than having the Xerox FreeFlow Print Server perform the composition. When creating
