In general, a control method of an embodiment is to control a setting screen which enables selection between a first mode for forming an image using a color material for non-removal and a second mode for forming an image using a color material for removal. When the first mode is set, the control method enables, on a setting screen, the setting of a punching post-processing for making a hole in an image receiving medium and a non-punching post-processing for making no hole in the image receiving medium, and when the second mode is set, on the setting screen, disables the setting of the punching post-processing, but enables the setting of the non-punching post-processing.

The present disclosure discloses a color gamut mapping method, an apparatus, and a storage medium in the technical field of displaying. The method includes: acquiring at least one color gamut type tag for at least one layer; determining at least one color gamut corresponding to the at least one layer, based on the at least one color gamut type tag; for each layer, mapping the layer to a corresponding color gamut by using a color gamut mapping method corresponding to the color gamut type; and superimposing the at least one layer that is mapped to the at least one corresponding color gamut so as to form and output an image to be displayed.

Methods and systems herein provide for color conversion of image data to another color space. Such color conversion includes converting image data to a color space by identifying color regions in the image data. One color conversion system herein includes a color region identifier operable to select color values in the image data, determine numerical centers of the selected color values, and generate color regions, or color value clusters, based on the selected color values and the numerical centers. The color conversion system also includes an optimization module operable to refine the numerical center of each color region, determine a boundary for each color region based on the refined center, and remove a portion of the color cluster centers to optimize a number of the color regions for color conversion processing.

There is provided a recording data generating apparatus that generates recording data used for reproducing a gloss of an image by recording inclined structures on a recording medium, the recording data generating apparatus including: a conversion unit that converts gloss data with a first resolution having an inclined structure as one pixel into inclined structure data representing a combination ratio of a predetermined number of kinds of inclined structures; a halftone processing unit that generates N-value quantization data representing one of the predetermined number of kinds of inclined structures by performing a halftone process of the inclined structure data of each pixel with the first resolution, N being equal to the predetermined number of kinds; and a recording data generating unit that generates recording data used for recording one of the predetermined number of kinds of inclined structures for each pixel with the first resolution based on the quantization data.

A color image processing device uses a dither pattern of blocks, each including a plurality of dots representing the gradations of each pixel of an image in a prescribed print region. The dots including one block are arranged in a growth sequence in the ascending order of gradation, and print data is written sequentially at the dots the number of which corresponds to the gradation associated with the block. An extracting unit extracts a data region holding the color components from the print data. A dither processing unit generates dither patterns for the color components extracted by the extracting unit. The dither processing unit detects whether one or more of the dots including each of the pixels forming the image are outside the data region, and moves any dot outside the data region to a certain dot including the same pixel and existing in the data region.

Method of setting up a color separation table for a specific print system, comprising finding first NP (Neugebauer Primary) area coverages of a specific print system that correspond to color values, adding second NP area coverages by converting halftone data from at least one pre-determined pair of halftone data and corresponding color value to NP area coverages, and generating a color separation table arranged as input for a halftone process that comprises color values linked to the corresponding first and second NP area coverages.

A raster image processor and a convolutional neural network or other artificial intelligence module operate in parallel. Image data for printing is passed to the raster image processor and the convolutional neural network. The raster image processor translates computer vector files and/or rasterizes bitmaps having higher or lower resolution than the output device to a raster image that includes a matrix of dots a printer can process. The raster image processor generates layers for process inks. The convolutional neural network generates a mask layer, based on the image, that is used by the raster image processor to generate an additional layer for spot colors, object colors, or specialty ink. The mask layer transmitted to the raster image processor generates a spot color layer. The layers generated by the raster image processor and the additional layer for the spot colors and/or specialty inks are combined into a print data file.
