What is manual color correction?
When manual color correction is enabled, the printer employs user-selected color conversion tables to process
objects.Manualcolorcorrectionsettingsarespecifictothetypeofobjectbeingprinted(text,graphics,orimages).

To apply a different color conversion table manually, see “Modifying the colors in printed output” on page 188.
IfthesoftwareprogramdoesnotspecifycolorswithRGBorCMYKcombinations,thenmanualcolorcorrectionisnot
useful. It is also not effective if the software program or the computer operating system controls the adjustment of
colors. In most situations, setting the Color Correction to Auto generates preferred colors for the documents.
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 sets are also available from
theColorSamplespageoftheEmbeddedWebServer.Selectinganysamplesetgeneratesmultiple-pageprints
consistingofhundredsofcoloredboxes.EachboxcontainsaCMYKorRGBcombination,dependingonthetable
selected.TheobservedcolorofeachboxisobtainedbypassingtheCMYKorRGBcombinationlabeledonthebox
through the selected color conversion table.
ByexaminingColorSamplessets,youcanidentifytheboxwithcolorclosesttothecolorbeingmatched.
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
use the selected color conversion table for the particular object.
Selecting which Color Samples set to use for a particular color-matching problem depends on:
-
TheColorCorrectionsettingbeingused(Auto,Off,orManual)
-
Thetypeofobjectbeingprinted(text,graphics,orimages)
