How can I match a particular color (such as a corporate logo)?
Nine types of Color Samples sets are available from the Quality menu on the printer control panel. These are also
available from the Color Samples page of the Embedded Web Server. Selecting any sample set generates a
multiple‑page printout consisting of hundreds of colored boxes. Either a CMYK or RGB combination is located on
each box, depending on the table selected. The observed color of each box is obtained by passing the CMYK or RGB
combination labeled on the box through the selected color conversion table.
By examining Color Samples sets, you can identify the box whose color is the closest to the color you want. The color
combination labeled on the box can then be used for modifying the color of the object in a software program. For
more information, see the help information of your operating system.
Note: Manual color correction may be necessary to utilize the selected color conversion table for the particular
object.
Selecting which Color Samples set to use for a particular color‑matching problem depends on the Color Correction
setting being used , the type of object being printed, and how the color of the object is specified in the software
program. When Color Correction is set to Off, the color is based on the print job information, and no color conversion
is implemented.
Note: The Color Samples pages are not useful if the software program does not specify colors with RGB or CMYK
combinations. Additionally, certain situations exist in which the software program or the computer operating
system adjusts the RGB or CMYK combinations specified in the program through color management. The resulting
printed color may not be an exact match of the Color Samples pages.
What are detailed color samples and how do I access them?
Detailed color samples sets are available only through the Embedded Web Server of a network printer. A detailed
Color Samples set contains a range of shades that are similar to a user‑defined RGB or CMYK value. The likeness of
the colors in the set is dependent on the value entered in the RGB or CMYK Increment box.
Color conversion tables
• Vivid—Produces brighter, more saturated colors and may be applied
to all incoming color formats.
• sRGB Display—Produces an output that approximates the colors
displayed on a computer monitor.
Note: Black toner usage is optimized for printing photographs.
•
Display‑True Black—Produces an output that approximates the
colors displayed on a computer monitor. This uses only black toner
to create all levels of neutral gray.
• sRGB Vivid—Provides an increased color saturation for the sRGB
Display color correction.
Note: Black toner usage is optimized for printing business graphics.
•
Off—No color correction is implemented.
• US CMYK—Applies color correction to approximate the SWOP
(Specifications for Web Offset Publishing) color output.
• Euro CMYK—Applies color correction to approximate Euroscale
color output.
• Vivid CMYK—Increases the color saturation of the US CMYK color
correction setting.
• Off—No color correction is implemented.
