• Process Black Graphics 
When this setting is selected, the black graphics of 
your documents are created by combining cyan, 
magenta and yellow toner to create a process black 
color. This feature may reduce gloss differences in 
some documents that have gray regions next to color 
regions. Black text is not affected. 
Graphics
Resolution
The resolution setting affects the amount of detail that is 
reproduced on graphic images. Graphics resolution is 
measured in dots per inch (dpi). Therefore, a 600 dpi 
setting renders images using 600 dots (pixels) per every 
inch of the image.
The image quality of printed documents typically 
increases with higher resolution (dpi) and bits per pixel 
settings, but it often results in slower print speed and 
increased toner consumption.

• Use Printer's Settings

halftone screen settings that are available on your 
DocuPrint NC60. See the section “Document Halftone”

 for available selections.
