Matching Method
This setting allows you to specify a method of printing when the <RGB Source Profile> is applied. This machine includes a color
management system that provides the following color rendering styles.
Perceptual
Saturation
Colorimetric
If <None> is selected for the <RGB Source Profile> or <CMYK Simulation Profile>, and the machine receives a device
dependent color space definition that is color processed by the host computer, a Matching Method setting is not applied.
<Menu> <Printer Settings>
<Perceptual>
This setting produces the best results for photographic or bitmapped images.
<Saturation>
This setting is best suited for printing illustrations and diagrams used in business presentations.
<Colorimetric>
This setting provides a close match to the RGB color value of the machine's printing range.
RGB Pure Black Process
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.
Off
On
If you can see gradations or jagged lines in the printouts of black or gray data, select <Off> in RGB Pure Black Process
and select <Photo> 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 <None> is selected for <RGB Source Profile>
When <TR Normal> or <TR Photo> is selected for <Output Profile>
When [Use 100% GCR Profile] in the printer driver is selected
If <None> is selected for <RGB Source Profile>, the RGB Pure Black Process setting is not applied.
