RGB Pure Black Process (PS Only)

Return to Overview


Off, On*


An asterisk (*) indicates the default setting in this section.

This setting enables you to specify how black and gray data with the equivalent ratio of R to G to B should be processed when device dependent RGB data is converted into device dependent CMYK data using the <RGB Source Profile> of the machine.

If <On> is selected, black and gray data with the equivalent ratio of R to G to B is printed using the black (K) toner only, regardless of the selected <Output Profile> setting.

If <Off> is selected, black and gray data with the equivalent ratio of R to G to B is printed using CMYK toners based on the selected <Output Profile> setting.


Remark
  • To use the PS printer driver with the machine, the optional PS Printer Kit is required.
  • If you can see gradations or jagged lines in the printouts of black or gray data, select <Off> for <RGB Pure Black Process> and select <Normal> for <Output Profile>.
  • In combination with certain settings, black and gray data with the equivalent ratio of R to G to B may be printed using the black (K) toner only, even if <Off> is selected. The following are examples.
  • When <On> is selected for <Pure Black Text>
  • When <TR Normal> or <TR Photo> is selected for <Output Profile>
  • When [Use 100% GCR Profile] in the printer driver is selected
