Image Quality (IQ)
Generally the image quality of a base printing system is 
above average and the Image Quality (IQ) enhancements 
filters provided within DocuSP is unnecessary. If you wish to 
improve output IQ, the DocuSP provides separate controls 
for enabling Anti Aliasing, Trapping, and Intelligent Black 
Overprint. 
Disabling all three of these IQ filters improves performance. If 
you are printing only a small number of copies, the expected 
increase in RIP time is 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 is devoted to the 
actual printing and the RIP performance decrease is 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.
On DC 2045/2060/6060/5252 and 8000 there are certain 
scenarios in which the printer will cycle down and do an 
Image Quality (IQ) adjustment. The percent area coverage of 
the page (that is, amount of image/text written on the page) 
also effects the number of IQ adjustments that the printer 
makes. 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  automatically generates 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.
The DC 2045/2060/6060 print engine also performs IQ 
adjustments if a difficult job is being processed and RIP falls 
behind the print output. If this occurs, the print engine will 
cycle down for a few seconds while the RIP catches up and 
then it performs an IQ adjustment which takes anywhere from 
5-95 seconds. During the IQ adjustment, the printer does not 
print anything. However, the RIP continues and be slightly 
ahead. As soon as the printer finishes the IQ adjustment it 
prints all of the RIPped pages and catch up with the printer.
