Pure Black Graphics
[On], [Off]*
This setting affects the printout for graphics printed in black (R=G=B=0%, C=M=Y=100%/Bk=N% or C=M=Y=0%/Bk=100%) (illustrations created in application software).
[On]
Black colors generated by applications are printed using only 100% black toner. This means that the color toner will not be misaligned since only one toner color (black) is used.
[Off]
Black graphics are printed using CMYK toners based on the settings in the selected Output Profile setting. For some jobs, it is preferable to turn this option [Off].
