System Guide | Hints and Tips |
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 will be more efficient than having the DocuSP perform the composition. When creating variable objects to be overlaid on fixed underlays or backgrounds, it is also important to ensure that the objects are properly cropped or bounded and at the lowest acceptable resolution. The DocuSP can compose 2 variable data objects of 2 inches by 2 inches and 300 dots/inch resolution about
Image Quality
Generally the image quality of a base printing system will be above average and the Image Quality (IQ) enhancements filters provided within DocuSP will be unnecessary. If you wish to improve output IQ, the DocuSP provides separate controls for enabling Anti Aliasing, Trapping, and Intelligent Black Overprint. Disabling all 3 of these IQ filters will improve performance. If you are printing only a small number of copies, the expected increase in RIP time will be visible as a significant fraction of the total job processing time. When printing documents with a large a number of copies, then the majority of the processing time will be devoted to the actual printing and the RIP performance decrease will be less visible (a smaller fraction of the total job time). You should examine the DocuSP printed output with the IQ enhancing filters enabled and disabled and decide whether the IQ improvement is worth the performance drop for this particular job scenario.
On DC 2045/2060/6060 there are certain scenarios where the printer will cycle down and do an Image Quality (IQ) adjustment. The % area coverage of the page (i.e. amount of image/text written on the page) also effects the number of IQ Adjustments that the printer will make. A standard letter size page (8.5x11 inches) is about 21.6x27.9 cm or about 603.5 square cm. If the text and images written to a page cover more than about 250 square cm (about 40% of the page), then the print engine will automatically generate IQ Adjustments. If you find that a particular document seems to take a long time to print because of IQ adjustments, improve performance by simplifying the page. For example, the text and images on the page might be downsized to cover less than 40% of the viewable area of the paper and the performance may improve because the printer does fewer IQ Adjustments.
