US 8,711,429 B2 · Systems and methods for printing images outside a normal color gamut in image forming devices

Abstract

A user of an image forming device selects from among a plurality of pre-stored color rendition dictionaries (CRDs) in order that a set of system process parameter setpoints associated with that CRD may be referenced to bias and/or skew an available color gamut in the direction of a particular nominally out-of-gamut color which the user wishes to produce in a color image output by the image forming device. A capability is included in a color image forming device store and/or update multiple sets of special process parameter setpoints defining a plurality of CRDs each of which may be identified and associated with a specific color in order that requests to print out-of-gamut colors may be satisfied routinely as exceptions to a nominal gamut based on a nominal set of stored setpoints when a CRD is selected and the setpoints associated with that CRD are input for reference by the color image forming device on a temporary basis.

Claims21

Dependent claims

A method for producing an output color image in an image forming device, comprising:

obtaining an input color image;
at least one of, adding color rendition dictionaries to, deleting color rendition dictionaries from, or modifying color rendition dictionaries in, a plurality of color rendition dictionaries stored in the image forming device based on input from a user;
selecting a color rendition dictionary from among the plurality of color rendition dictionaries;
setting setpoint values for a plurality of process parameters in the image forming device based on the selected color rendition dictionary;
and
producing an output color image using the image forming device in which the setpoint values have been set,
wherein the plurality of stored color rendition dictionaries includes at least one color rendition dictionary which is usable to produce a non-standard gamut color in the produced output color image.
