Hints and Tips9-6 System GuideJob RIP hintsIf using the default media/color settings that are pre-loadedon the controller, the DocuSP process built in color spacetransformations to accelerate RIP performance. If you do anyof the following, the color space transformation probablytakes 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 spacetransformations are slower than CMYK transformations. If theinput images of a job can be created in CMYK color space,then the DocuSP are able to process the job more efficiently.Variable dataVariable data job construction is also an important driver ofRIP performance. Jobs that are constructed with a singleunderlay or background plane and a small number of variabletext or image overlays run very efficiently. If the same job isconstructed with the underlay constructed from severaldistinct objects which the DocuSP is asked to compose onthe fly, then the job is not able to take advantage of theDocuSP variable data performance enhancement. In thatcase, the job may RIP significantly slower than the moreefficiently constructed job.For cases where the background/underlay of the variabledata job is composed of 2 or 3 relatively static objects, it issuggested to have the application create each staticcombination of objects as a different underlay. This is moreefficient than having the DocuSP perform the composition.When creating variable objects to be overlaid on fixedunderlays or backgrounds, it is also important to ensure thatthe objects are properly cropped or bounded and at thelowest acceptable resolution. The DocuSP can compose 2variable data objects of 2 inches by 2 inches and 300 dots/inch resolution about 10-20 times faster than it could if thesame objects were 600 dpi and 8.5x11 inches.
