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.
Prints on color transparencies appear dark when projected
Note: This problem occurs when projecting transparencies with reflective overhead projectors. To obtain the
highest projected color quality, transmissive overhead projectors are recommended.
Action
Step 1
From the printer control panel, make sure the paper type setting
is set to Transparency.
Is the paper type setting correct?
Step 2
Reduce the toner darkness, and then resend the print job.
Does the print on the color transparency look lighter?
Color conversion tables
•
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.
