You can overprint device-dependent CMYK data as composite
output.Since all the colors used in the data are overprinted to a
single palette, you can check the result without performing color

If [CMYK Sim. Profile] is set as a value other than [None], the
setting for this item becomes invalid.
Specify whether to use the smoothing process to smooth the edges
of graphics (illustrations created in other applications) or text.
[Smooth 1] is better than [Smooth 2] for performing a smoothing
process that provides more smoothing.
You can select what to smooth by switching [Graphics] and [Text]:
[On]/[Off].
Select the method for converting color print data to grayscale for
printing.
When it is set to [sRGB], it calculates the grayscale value using
the sRGB standard color conversion method.
When it is set to [NTSC], it calculates the grayscale value using
the NTSC standard color conversion method.
When it is set to [Uniform RGB], it takes the average value of
the Red, Green and Blue color values as the grayscale value.
If [Color Mode] is set as [Auto (Color/Black)] and [Color], the
setting for this item becomes invalid.
