A printer includes an ejection head and a controller. The ejection head includes a nozzle configured to eject sublimation ink to a transfer sheet. The controller is configured to acquire an inspection image indicating transfer unevenness. The transfer unevenness is generated when an image on the transfer sheet is transferred to a recording medium by heat press. The controller is configured to change an image to be formed on the transfer sheet based on the inspection image.

Provided are a control apparatus, an image processing method and a non-transitory recording medium. The control apparatus includes a raster-image processor and a hardware processor that judges whether each of multi-valued pixels forming a source image is colored in one of specific colors, controls the amount of color materials to be used in printing the source image together with a white base, by reducing pixel values of the multi-valued pixels forming the source image and the white base, and converts the multi-valued pixels into two-valued pixels corresponding to colors of the color materials of the source image and two-valued white pixels. The hardware processor uses a matrix of two-valued white pixels corresponding to each of the multi-valued pixels judged as being colored in one of the specific colors, to rearrange at least one of colored two-valued white pixels at colored or uncolored pixel positions in the matrix.

An image processing apparatus extracts provisional band data from image data. The apparatus calculates near white number for a target line. The near white number is number of pairs of first and second pixels. The first pixel is located on the target line, the second pixel is in positionally adjacent relation to the first pixel. At least one of the first pixel and the second pixel is a near white pixel. In a case where a prescribed border condition is met for the target line, the apparatus determines finalized band data so that a finalized band image includes at least part of the provisional band image, and has the target line as a borderline. In a case where a specific condition is met, the apparatus changes the target line to one of a plurality of candidate lines which is not selected as the target line.

A recording device includes a recording unit, a scanning unit, and a recording control unit. The recording unit includes first and second recording parts each having multiple discharge orifice rows that each have multiple discharge orifices arrayed in a predetermined direction. The first recording part and the second recording part are separated from each other in an intersecting direction that intersects the predetermined direction. The scanning unit performs recording scanning by moving the recording unit. The recording control unit performs recording of a region on the recording medium including one edge of the recording medium by the first recording part alone, recording of another region including the other edge of the recording medium by the second recording part alone, and recording of a region in between the two regions using both recording parts.

A printing apparatus includes a first nozzle which ejects first ink containing a black coloring material, a second nozzle which ejects second ink with a low content rate of the coloring material compared to the first ink, and a control unit which controls ejecting of the ink from the first and second nozzles, in which, in a case of printing a darkest point, the control unit causes the second ink to be ejected after causing the first ink to be ejected, and causes the second ink to be ejected from the second nozzle so that a use rate of the second ink becomes 1% or more and 15% or less, when causing the second ink to be ejected.

A three-dimensional image forming system according to an embodiment of the present invention is a system that expands the front side of a thermally expandable sheet formed by laminating a thermally expanding layer on a base material and forms irregularities in a desired area, the system includes a print data density adjusting unit that adjusts, in print data for printing, on the back side of the thermally expandable sheet, a grayscale image for expanding the thermally expandable sheet to a surface height according to a density, the density of an outline part obtained by setting a region from a boundary between adjacent two regions having different densities in the grayscale image to a predetermined distance as the outline part in at least either of the two regions having different densities such that steep steps are formed on the front side of the thermally expandable sheet at the boundary.

A printing apparatus has a plurality of nozzles capable of discharging dark ink and light ink that are of the same type color; the plurality of nozzles includes preceding nozzles that discharge the ink onto the printing medium before the ink discharge of the other nozzles, and succeeding nozzles that discharge the ink onto the printing medium after the ink discharge of the preceding nozzles, and if the amount of the dark ink discharged on the printing target region is larger than a predetermined amount, the printing apparatus discharges a smaller amount of the light ink than the amount of the discharged dark ink onto the printing target region from the plurality of nozzles so that the amount of the light ink discharged from the succeeding nozzles is larger than the amount of the light ink discharged from the preceding nozzles.

A printing apparatus including a discharge unit, a movement unit and an adjustment unit. The discharge unit discharges ink and penetration liquid onto one side of the recording medium. The penetration liquid promotes penetration of the ink into the other side of the recording medium. The movement unit moves the discharge unit and the recording medium relative to each other. The adjustment unit adjusts a discharge amount of the penetration liquid discharged from the discharge unit onto the recording medium based on at least a relative movement speed of the discharge unit to the recording medium.

A printing system includes a machine readable storage medium storing instructions and a processor to execute the instructions. The processor is to execute the instructions to receive a source image comprising a plurality of regions and analyze each region of the plurality of regions to determine an ink density of each region. The processor is to execute the instructions to further in response to the ink density for a region exceeding a threshold, deplete the ink density for the region; and in response to the ink density for a region not exceeding the threshold, maintain the ink density for the region. The processor is to execute the instructions to further combine the depleted regions and the maintained regions to generate an optimized image.

A printing apparatus has a plurality of nozzles capable of discharging dark ink and light ink that are of the same type color; the plurality of nozzles includes preceding nozzles that discharge the ink onto the printing medium before the ink discharge of the other nozzles, and succeeding nozzles that discharge the ink onto the printing medium after the ink discharge of the preceding nozzles, and if the amount of the dark ink discharged on the printing target region is larger than a predetermined amount, the printing apparatus discharges a smaller amount of the light ink than the amount of the discharged dark ink onto the printing target region from the plurality of nozzles so that the amount of the light ink discharged from the succeeding nozzles is larger than the amount of the light ink discharged from the preceding nozzles.
