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

Occasionally, you may have a need for the printed color of a particular object to closely match a specific color. For

example, you may need to match the color of a corporate logo. While instances can occur in which the printer

cannot exactly reproduce the desired color, you should be able to identify adequate color matches for the majority

of cases.
The Color Samples menu item can provide useful information in helping solve this particular type of color-matching

problem. The nine Color Samples values correspond to color conversion tables in the printer. Selecting any of the

Color Samples values 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.
You can examine the color samples pages and 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

application. For instructions, see the software application Help. Manual Color Correction may be necessary to utilize

the selected color conversion table for the particular object.
Selecting which Color Samples pages 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 application (RGB or CMYK combinations). When the

printer Color Correction setting is set to Off, the color is based on the print job information; no color conversion is

implemented.

Note: The Color Samples pages are not useful if the software application does not specify colors with RGB or CMYK

combinations. Additionally, certain situations exist where the software application or the computer operating

system adjusts the RGB or CMYK combinations specified in the application through color management. The

resulting printed color may not be an exact match of the Color Samples pages.

The following table can help identify which Color Sample pages to use for color matching.
