Manual Color menu

Object type	Color conversion tables
RGB Image	• Vivid—Produces brighter, more saturated colors and may be applied
RGB Text	to all incoming color formats.
RGB Graphics	• sRGB Display—Produces an output that approximates the colors
	displayed on a computer monitor. Black toner usage is optimized for
	printing photographs.
	• Display—TrueBlack—Produces an output that approximates the
	colors displayed on a computer monitor. Uses only black toner to create
	all levels of neutral gray.
	• sRGB Vivid—Provides an increased color saturation for the sRGB
	Display color correction. Black usage is optimized for printing business
	graphics.
	• Off—No color correction is implemented.
CMYK Image	• US CMYK—Applies color correction to approximate the SWOP
CMYK Text	(Specifications for Web Offset Publishing) color output.
CMYK Graphics	• Euro CMYK—Applies color correction to approximated EuroScale color
	output.
	• Vivid CMYK—Increases the color saturation of the US CMYK color

How can I match a particular color (such as a corporate logo)?

From the printer Quality menu, nine types of Color Samples sets are available. 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, a user can identify the box whose color is the closest to the desired color. 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 software program Help topics. 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 (Auto, Off, or Manual), the type of object being printed (text, graphics, or images), and how the color of the object is specified in the software program (RGB or CMYK combinations). When the printer Color Correction setting 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.
