What is Manual Color Correction?
The color conversion tables applied to each object on the printed page when using the default Auto Color
Correction setting generate preferred color for the majority of documents. Occasionally a user may want
to apply a different color table mapping. This customization is accomplished using the Manual Color menu
and the Manual Color Correction setting.
Manual Color Correction applies the RGB and CMYK color conversion table mappings as defined in the
Manual Color menu. Users may select any of four different color conversion tables available for RGB
objects (sRGB Display, sRGB Vivid, Vivid, and Off) and any of four different color conversion tables
available for CMYK objects (US CMYK, Euro CMYK, Vivid CMYK, and Off).
Note: The Manual Color Correction setting is not useful if the software application does not
specify colors with RGB or CMYK combinations, or in certain situations where the
software application or the computer's operating system adjusts the colors specified in
the application through color management.
How can I match a particular color (such as a color in a corporate logo)?
Occasionally users have a need for the printed color of a particular object to closely match a specific color
of interest. A typical example of this is when a user is trying to match the color of a corporate logo. While
instances can occur in which the printer cannot exactly reproduce the desired color, users should be able
to identify adequate color matches for the majority of cases. The Color Samples menu items can provide
useful information in helping to solve this particular type of color matching problem.
The eight Color Samples options correspond to color conversion tables in the printer. Selecting any of the
Color Samples options will generate a multi-page printout consisting of hundreds of colored boxes. Either a
CMYK or RGB combination will be located on each box depending upon 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.
The user can scan 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. The software application's Help section should provide instructions for modifying an
object's color. Manual Color Correction may be necessary to utilize the selected color conversion table for
the particular object.
