Examples relate to providing synchronized look-up table loading. In some examples, a print job is processed using an initial look-up table in processor memory. In response to the processing of the print job reaching a buffer trigger row of a portion of the print job, look-up metadata is accessed to locate a next look-up table. At this stage, the next look-up table is dynamically loaded into the processor memory as the processor continues to process the print job, where the processing of the print job begins using the next look-up table after a target row of the portion of the print job is reached.

An image forming apparatus includes an image forming unit configured to form an image on a sheet, a conveyance unit configured to convey the sheet from the image forming unit to a reading position, a sensor configured to output a signal synchronized with a conveyance speed of the conveyance unit, a reading unit configured to read the sheet while the sheet conveyed by the conveyance unit passes through the reading position, and an adjustment unit configured to adjust, based on a reading result of the sheet read by the reading unit and the signal output by the sensor, misregistration between an image to be formed on a first surface of the sheet by the image forming unit and an image to be formed on a second surface of the sheet by the image forming unit.

A printing apparatus has a plurality of nozzles including preceding nozzles that discharge ink onto a printing medium before ink discharge of the other nozzles, and succeeding nozzles that discharge ink onto the printing medium after the ink discharge of the preceding nozzles, and if the amount of black ink discharged on the printing target region is larger than a predetermined amount, the printing apparatus discharges a smaller amount of chromatic ink than the amount of the discharged black ink onto the printing target region from the plurality of nozzles so that the amount of the chromatic ink discharged from the succeeding nozzles is larger than the amount of the chromatic ink discharged from the preceding nozzles.

An image capturing unit includes a sensor unit that image-captures a predetermined area including a subject; and a reference chart unit that is arranged in the predetermined area and captured with the subject by the sensor unit.

An ink amount upper limit setting apparatus includes a target color designating section that accepts the designation of at least one target color for which an ink amount upper limit is to be set. A patch controller causes an output device to form patches in accordance with output values. A colorimetric value acquiring section acquires colorimetric values of the formed patches. A color reproduction determination output section outputs color reproduction determination information that indicates whether the target color is contained in a color reproduction region for each of ink amount upper limit candidates, on the basis of a coordinate value of the target color and the colorimetric values.

Provided is an image recording apparatus, including: a recording unit recording an image on a recording sheet; a conveying unit conveying a plurality of recording sheets in an overlapping state to the recording unit; and a setting unit setting an overlapping amount so that the image is prevented from being printed on a region of a predetermined range which includes a boundary between an overlapping portion, in which a subsequent sheet and a preceding sheet overlap each other, and a non-overlapping portion, in which the subsequent sheet and the preceding sheet do not overlap each other.

An inkjet printer for printing labels includes: a first interface configured to receive, from a host computer, print data for images to be printed on the labels; a second interface configured to receive, from a sequencer, a first signal indicating a timing to execute a printing operation that includes printing the images, and a second signal indicating a timing to execute a predetermined operation that cannot be executed in parallel with printing the images; and a controller configured to: render the print data received via the first interface, and execute the printing operation based on the rendered print data at a timing based on the first signal received via the second interface, and execute the predetermined operation at a timing based on the second signal received via the second interface.

A printing device prints a patch chart including a plurality of first patches having a predetermined color and one or more second patches having a user specified color. A measuring member measures a color of a patch. The patch chart includes a plurality of patch columns having two or more patches among the plurality of patches arranged linearly. In a case that a patch column of the plurality of patch columns includes a second patch of the plurality of second patches, a controller performs a calibration process to calibrate the measuring member by controlling the measuring member to measure a color of a reference; and after the calibration process is completed, a color measurement process for a patch included in the patch column including the second patch, the color measurement process for the patch being to control the measuring member to measure a color of the patch.

A printing apparatus includes: a main controlling circuit; a sub-controlling circuit group including sub-controlling circuits connected in series; and heads. The print data includes data of a plurality of pixels. The main controlling circuit is configured to execute: generation of, based on the print data, data of first to n-th pixel groups regarding the first to n-th pixel groups each including pixels which are not adjacent (n2), and transmission of the data of the first to n-th pixel groups to the sub-controlling circuit group. Each of the plurality of sub-controlling circuits is configured to execute: obtainment of data of pixels which are associated with each of the plurality of sub-controlling circuits, from the data of the first to n-th pixel groups, and driving of one of the plurality of heads corresponding thereto, based on the data of the pixels.
