A color printing device can include a print engine, a circuit, and a processor. The print engine prints onto physical media using different color colorants. The circuit has data-processing color channels corresponding to the different color colorants. The processor receives monochromatic print jobs and transmits the received monochromatic print jobs to unused color channels of the color channels for processing in parallel. The processor can transmit the processed monochromatic print jobs to the print engine for printing.

A white balance adjustment device includes a statistics acquisition portion and a correction portion. The statistics acquisition portion includes an area setting portion including a luminance area setting portion configured to set a plurality of luminance ranges, and an average value calculation portion configured to calculate an average value of color difference values of the image signal in each of the plurality of luminance ranges set by the luminance area setting portion. The correction portion includes a correction function determination portion configured to determine a correction function of the color difference values of the image signal based on the average value of the color difference values calculated by the average value calculation portion, and a color difference correction portion configured to correct the color difference values of the image signal based on the correction function determined by the correction function determination portion.

An image processing device is communicable with a printer and includes a controller. The printer is configured to repeatedly and alternately execute a partial print and a sub scan to form an image. The image is made up of a plurality of partial images arranged in a sub scanning direction. The partial print forms a target partial image while performing a main scan. The controller is configured to perform: setting; generating; and outputting. The setting sets a printing direction for the partial print to one of first and second directions. The generating generates partial print data for the partial print by executing a color conversion process on target partial image data using a color conversion profile. The color conversion profile is selected from first and second profiles respectively corresponding to the first and second directions. The outputting outputs the partial print data and direction information specifying the printing direction.

In an image processing device, a controller is configured to perform: selecting; generating; and outputting. The selecting selects a target partial image one by one from a plurality of partial images. The target partial image is represented by target partial image data. The generating generates partial print data for a partial print by executing an image process on the target partial image data. The partial print forms the target partial image while moving a print head in a printing direction. The partial print forms the target partial image while moving a print head in a printing direction. The image process includes a color conversion process. The color conversion process is executed on the target partial image data using one of a first profile and a second profile selected in accordance with the printing direction set for the partial print. The outputting outputs the partial print data to the printer.

An image processing apparatus includes a receiver and a correcting unit. The receiver receives a first read value and a second read value. The first read value indicates a result of reading a first color by a reader from a recording medium in which the first color is applied to a first area in which in-plane density unevenness is confirmable within the recording medium. The second read value indicates a result of reading a second color by the reader. The second color is different from the first color and is applied to a second area that is substantially the same as the first area in a superimposed manner. The correcting unit corrects in-plane density unevenness of the second color applied to the first color in the superimposed manner based on the first read value received by the receiver and the second read value received by the receiver.

A color conversion system includes a first colorimetric input machine having a first color gamut and performing colorimetry of an object to output a first colorimetric value; an input portion to which the first colorimetric value is input; a converting portion converting the first colorimetric value to a second colorimetric value; and an output portion outputting the second colorimetric value. The converting portion stores a first colorimetric value table having color information about each measurement light source used when performing colorimetry by the first colorimetric input machine, and a second colorimetric value table having color information about each measurement light source used when performing colorimetry by a second colorimetric device having a second color gamut, and converts the first colorimetric value to the second colorimetric value by causing colorimetric values of the first colorimetric value table to correspond to colorimetric values of the second colorimetric value table.

A print system with a ratio-based adaptive switching technique includes a printing unit to print an image on a recording medium in a color mode or a monochrome mode. A number (cM) of monochrome pages printed in the color mode and a total number (pN) of printed pages are monitored. A ratio cM/pN that is indicative of excess cartridge wear of the print system is determined. Print-job performance and cartridge wear of the print system are optimized based on the determined ratio using a first and second threshold.

Provided are an image processing apparatus, an image processing method, a program, and an image recording apparatus capable of suppressing occurrence of banding and color unevenness without productivity decrease. Different types of nozzle jetting rates are reflected in image data of each of a first color and a second color that are two different plural colors to perform conversion of a gradation value of each pixel, and halftone processing is performed with respect to the converted image data. A first nozzle jetting rate to be reflected in a gradation value of the first color is set so that a nozzle jetting rate of an end part nozzle at each of both end parts of a nozzle row is suppressed to be smaller than a nozzle jetting rate of a central nozzle. A second nozzle jetting rate to be reflected in a gradation value of the second color has a smaller difference between the nozzle jetting rate of the end part nozzle and the nozzle jetting rate of the central nozzle compared with the first nozzle jetting rate.

A networked product imaging system includes devices that provide the production of imaged goods. Sellers are easily integrated into the network with minimal or no inventory requirements. Customer requirements are provided to a central computing device (CCD) that has two-way communication with a plurality of geographically separated product image forming devices. The central computing device determines specifications for forming the image on the blank product in accordance with the customer's order. The central computing device selects a product image forming device from the plurality of geographically separated product forming devices for fulfilling the order, based upon factors that include the specification of the product image forming device available, the product image forming inventory and the blank product inventory available at the geographic location of the product image forming device. The selected product image forming device forms the image on the blank product at the remote location.
