There is provided a printing apparatus including an obtaining unit configured to obtain print data in which in imposition image data in which one or more images are imposed in a print region, a code for identifying each image in the imposition image data is embedded; a determination unit configured to determine an ink color to be used to print the code by excluding an ink color satisfying a predetermined condition from candidates for the ink color to be used to print the code; and a print control unit configured to print the code based on the print data obtained by the obtaining unit using a plurality of nozzle arrays for the ink color determined by the determination unit.

An apparatus comprises a unit configured to generate gradation data corresponding to an achromatic color generated by combining two or more colors among a plurality of colors, for an excess amount of a total gradation value exceeding a predetermined value, the total gradation value being a sum of gradation values of the plurality of colors used for recording a pixel of interest, and generate gradation data corresponding to the plurality of colors, based on the generated gradation data corresponding to the achromatic color; and a unit configured to quantize the generated gradation data, and generate data to control recording of dots corresponding to the pixel of interest. The predetermined value is a gradation value indicating whether or not to record the dots in an overlapping manner, in case that the dots corresponding to the total gradation value are recorded.

In an example, a method includes determining, by processing circuitry, an element set to be associated with a print addressable location for printing an article in a one-pass print mode. The element set may comprise a plurality of elements, wherein each element identifies a print material or print material combination and is associated with a probability that the print material or print material combination identified by that element is to be applied to the associated print addressable location. Determining the element set for printing in a one-pass print mode may comprise favouring elements identifying individual print materials over elements identifying print material combinations.

A system for performing color validation by comparing a color measurement result of a chart and a color reference, the system including a first information processing apparatus, wherein the first information processing apparatus includes a colorimetric setting for performing color validation by comparing a color measurement result of a chart and a color reference, a transmission unit configured to transmit screen information of a screen for receiving a chart printing instruction, a receiving unit configured to receive the colorimetric setting and the chart printing instruction, and a generation unit configured to generate print data of a chart based on the colorimetric setting and the chart printing instruction.

In an image processing apparatus, a processor sets a target printing method for printing a target image to one of a bidirectional printing method and a unidirectional printing method. In a case where the bidirectional printing method is set as the target printing method: the processor executes both a first generation process and a second generation process. The first generation process generates first partial print data by converting a set of partial image data using a first color conversion profile. The second generation process generates second partial print data by converting another set of partial image data using a second color conversion profile. In a case where the unidirectional printing method is set as the target printing method, the processor executes a third generation process generating third partial print data by converting a set of partial image data using a third color conversion profile.

A non-transitory computer-readable medium stores computer-readable instructions. The instructions instruct a computer to perform processes including an acquisition step, a determination step, and a display step. The acquisition step includes acquiring a specified color. The determination step includes determining whether a device-independent color based on the specified color is present within a first color gamut based on first print settings of a printer. The display step includes displaying, when it is determined that the device-independent color is not present within the first color gamut, second print settings of the printer. The second print settings are different from the first print settings and cause a distance between the device-independent color and a second color gamut that is based on the second print settings to be smaller than a distance between the device-independent color and the first color gamut.

An optical scanning unit includes a rotatable multi-faceted mirror having a plurality of faces reflecting light flux emitted from a light source to scan a scanning area in a main scanning direction. A width of the light flux striking the rotatable multi-faceted mirror is smaller than a length of a face of the rotatable multi-faceted mirror. The entire of light flux striking the rotatable multi-faceted mirror is reflected at a first face when the light flux reflected by the rotatable multi-faceted mirror is directed to the center portion of the scanning area. A part of the light flux striking the rotatable multi-faceted mirror is reflected at the first face while the remaining of the light flux is reflected at a second face when the light flux reflected by the rotatable multi-faceted mirror is directed to a least one of the two end portions of the scanning area.
