Abstract: The present invention is directed to an information processing apparatus, the method comprising: detecting whether a sheet is set in a measurement device in accordance with a detection condition; in a case where a sheet is detected as being set, measuring a patch formed on the sheet, using the measurement device; and setting a first detection condition for detecting that a sheet is set in the measurement device and a second detection condition for detecting that a sheet is not set in the measurement device to mutually-different conditions.

Abstract: An information processing apparatus includes a color measurement unit configured to perform color measurement on a color chart on which a job identifier is printed by a printing apparatus, and a verification processing unit configured to perform color verification on an image printed by the printing apparatus corresponding to the job identifier, based on a color measurement value measured by the color measurement unit, and the job identifier.

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 information processing apparatus operable to perform colorimetry using a colorimeter that performs colorimetry of a colorimetric target based on reflected light obtained by irradiating illumination light onto the colorimetric target. The information processing apparatus loads a control program of a connected colorimeter before confirming a colorimeter to be used for colorimetry, executes the control program and receives an operation event of an operation performed on the connected colorimeter, and in response to the operation event, controls so as to confirm the colorimeter as a colorimeter to be used, or cause the colorimeter to wait until usage preparation, or confirm the colorimeter as a colorimeter to be used and request execution of calibration.

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: In a document represented by CMYK process colors, a color that a user wishes to remove is prevented from remaining without being removed by specified color removal, and even a color that the user does not wish to remove by rights is prevented from being removed.

Abstract: An image forming unit forms a toner image on an image carrier using toner. A transfer unit transfers the toner image to a sheet. A cleaner removes, from the image carrier, residual toner that was not transferred to the sheet by the transfer unit. In a detection mode for detecting a part of the image forming apparatus causing a streak, a controller may control the image forming unit to form a pattern on the image carrier, control the transfer unit so that the pattern passes through a transfer position without transferring the pattern to the sheet, control the cleaner to remove the pattern on the image carrier, and control the transfer unit to transfer a residual streak from the image carrier to the sheet. The residual streak occurs from the pattern image by causing an error of the cleaner.

Abstract: For a dither matrix used when converting multivalued data into image data for an output apparatus, thresholds are set such that a first dot and a second dot alternately become larger until both of the first dot and the second dot reach a first dot size, after both of the first dot and the second dot reach the first dot size, the first dot becomes larger until the first dot reaches a second dot size while the second dot does not become larger, and, thereafter, the second dot becomes larger until the second dot reaches the second dot size while the first dot does not become larger, and after both of the first dot and the second dot reach the second dot size, the first dot and the second dot alternately become larger.
