Specify how black or gray areas in images are printed.
Auto
Line art and texts are printed using black ink only. Images are printed using black ink only if they contain only white (RGB values are all 255), black (RGB values are all 0), or gray (RGB values are all the same value). Images are printed in four colors (CMY+K) if they contain any other colors.
CMY + K
Black and gray areas in the drawing are printed in four colors (CMY+K).
CMY
Black and gray areas in the drawing are printed in three colors (CMY).
Black
Black and gray areas in the drawing are printed using black ink only. Unwanted hue and luster are suppressed compared to the case where black is printed using CMY+K, and the purity of the black can be increased.
Default: Auto
Specifying Grey Reproduction is effective when "Colour" is selected in "81. Colour Mode".
This setting may not have any effect in some cases, depending on the application you use to print data. For instance, black or gray elements may be printed in four colors (CMY+K), even if you select "Black" to print them using black ink only.
When "CMY + K" is selected, areas where more than one element overlaps may not be printed correctly, depending on the application you use to print data. If this is the case, select "CMY".
The printed images may appear tinted when "CMY" is selected. Also, the areas of solid fill and line art composed of three colors (CMY) are printed using black ink, and fine moiré patterns may appear in such areas.
