Abstract: An information processing apparatus comprises acquiring information related to a chart to be printed, the chart including a plurality of patches arranged adjacent to each other; causing a display unit to display a plurality of patch displays according to a plurality of expected colors of the plurality of patches being acquired, and a procedure of sequentially measuring, by a colorimetric apparatus, the plurality of patches formed on the chart; sequentially acquiring measured values measured by the colorimetric apparatus; and sequentially displaying objects indicating measured colors, based on the measured value for each patch being acquired in a manner superimposed on a part of the patch display according to a corresponding expected color such that a display portions of the expected colors are connected between at least one pair of adjacent patch displays even after the objects are displayed.

Abstract: An object is to match the texture of a printed material, in addition to the tint, between different printing devices. In order to implement this object, a printed material output by a destination device is scanned and whether a certain area in image data obtained by the scan is an area printed in K color on the printed material or an area printed in CMY color mixture is determined. Then, based on the determination results, a printing parameter is determined.

Abstract: An image forming apparatus analyzes image data received by a receiving unit, determines whether or not there is a toner applied region in which an amount of toner to be transferred to a sheet is larger than the first threshold and smaller than the second threshold, sets the fixing temperature of a fixing unit to the first temperature when it is determined that there is not the toner applied region, and sets the fixing temperature of the fixing unit to the second temperature higher than the first temperature when it is determined that there is the toner applied region and an ambient state sensed by an environment sensor indicates a high-humidity environment.

Abstract: To make it possible for a user to easily grasp, at the time of selection of a measuring device and a chart, which are necessary for color verification of a printer, whether or not it is possible to use them. Based on a chart configuration information indicating the configuration of a chart on which a color patch is arranged and specification information indicating specifications of a measuring device that is used for colorimetry of the color patch, determination processing to check whether it is possible to perform colorimetry is performed. Then, results of the determination processing are output to be presented to a user.

Abstract: It is made possible to perform appropriate color matching between devices irrespective of whether a printed material is print-output in color or monochrome from a destination device. The color characteristic of the destination device is obtained by printing a chart in which a predetermined density pattern is formed in the destination device and reading the color of the chart. Next, whether the chart output from the destination device is color or monochrome is determined. Then, color conversion parameters for reproducing the color characteristic of the destination device in an adjustment device are determined by printing the color chart in a case where the printed material is determined that formed in color or printing the monochrome chart in a case where the printed material is determined that formed in monochrome in the adjustment device.

Abstract: An image processing apparatus for processing image data to be used for image formation, comprises: a black background area determination unit configured to determine a black background area formed from a plurality of black lines using the number of consecutive black lines and the number of consecutive lines adjacent to the black lines and other than the black lines out of the image data; and a thinning processing unit configured to perform thinning processing for the black background area by switching a thinning pattern to convert a value of a pixel based on the number of lines included in the black background area determined by the black background area determination unit.

Abstract: An image forming apparatus analyzes image data and detects a first area and a second area in the image data. The first area is an area in which a toner application amount per unit area is greater than a first threshold value and less than a second threshold value, and the second area is an area in which a toner application amount per unit area is greater than a third threshold value that is greater than the second threshold value. The image forming apparatus sets a target fixing temperature for fixing toner to a sheet based on the analyzing of the image data such that the target fixing temperature is set to be higher in a case in which one of the first area and the second area is detected than in a case in which none of the first area and the second area is detected.

Abstract: Provided is an image processing apparatus including an image processing unit that generates a binary image in which the width of a black line has been changed, the binary image constituted by black and white pixels. The image processing apparatus includes a first replacement unit that replaces a white pixel in a first binary image by a black pixel and replaces a black pixel in the first binary image by a white pixel, to generate a second binary image, and a second replacement unit that replaces, in the second binary image in which the width of a black line has been thickened by the image processing unit, a white pixel by a black pixel and replaces a black pixel by a white pixel.
