摘要： The disclosure relates to a method for color correcting a digital printer over a printing width of the digital printer, having the steps of: a) providing a specified digital image, said digital image having at least one color channel pattern, wherein each color channel pattern is assigned to a print color channel of the digital printer; b) determining at least one test color of the specified digital image; c) generating a digital test pattern, said digital test pattern being provided with at least one single-colored test strip which is designed to be printed over the printing width of the digital printer, d) printing the digital test pattern using the digital printer; e) detecting the color values of the printed test pattern on the basis of the position thereof in the direction of the printing width using an optical color measuring device; f) generating correction data for the digital printer using the detected color values; and g) using the correction data on the digital printer and/or the specified digital image. The method is suitable in particular for color correcting substantially single-colored prints and for reducing the formation of stripes in the printing direction.

摘要： A redundantly printed security-enhanced document, printing method, and system for better ensuring that the meaning of the information imparted by variable indicia printed by redundant printing indicia on a document protected by a removable Scratch-Off Coating (SOC). By printing the variable indicia with multiple colors, redundancy and integrity of the intended indicia is achieved relative to the perception of human eye photoreceptor cones. The redundantly printed document, methods, and systems enhance the overall appearance of the redundantly printed document, and reduce possible consequences resulting from misprinted variable indicia.

摘要： An information processing apparatus includes a processor configured to, in a case where a first color material, a second color material, a third color material, and a fourth color material in which a difference between the first color material and the fourth color material in a color space is less than a threshold value, are capable of being used, output combinations of values of color materials reproducing a first color, which is used for expanding a color gamut of a secondary color of the first color material and the second color material, and a second color, which is used for expanding a color gamut of a secondary color of the first color material and the third color material.

摘要： 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.

摘要： 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.

摘要： An optical writing device, and a method of controlling the optical writing device. The optical writing device and the method includes controlling speed of operation of a light deflector based on image magnifying-power information in a sub-scanning direction parallel to a direction in which a surface of a photoconductor moves, and controlling a prescribed write clock frequency such that a number of clock pulses of write light will become a target number of pulses over a period where the write light scans an area within a prescribed distance in a main scanning direction, the target number of pulses being maintained even when the speed of operation of the light deflector is changed in the controlling the speed of operation of the light deflector. The write clock frequency controller maintains the target number of pulses even when the speed of operation of the light deflector is changed by the light-deflector controller.
