A colorimetric method is executed by a server that communicates with an information processing apparatus coupled to a printing apparatus and to a colorimetric device. The method includes: creating work information that includes print commanding information related to a command to print a chart image based on chart information and also includes colorimetry commanding information related to a command to perform colorimetry for the chart image; storing the work information; transmitting the print commanding information to the information processing apparatus; causing the information processing apparatus to command, according to the print commanding information, the printing apparatus to print the chart image; transmitting the colorimetry commanding information to the information processing apparatus; and acquiring colorimetry result information created as a result of the colorimetry performed for the chart image by the colorimetric device.

An image processing apparatus includes a control unit configured to control execution of monochromatic calibration and multi-color calibration, and a registration unit configured to register paper types of paper to be used at time of execution of the monochromatic calibration, a monochromatic target value set for each of the paper types used for the monochromatic calibration, paper types of paper to be used at time of execution of multi-color calibration, and a multi-color target value set for each of the paper types used for the multi-color calibration. The image processing apparatus executes the multi-color calibration, after executing the monochromatic calibration, via the control unit by using paper of a paper type selected from common paper types out of the registered paper types and the monochromatic target value and the multi-color target value set for the selected paper type.

An image forming apparatus includes a plurality of light emitting elements, a detector, a controller, and an image forming unit. The light emitting elements are arranged in at least one row. The detector is configured to detect a number of light emitting elements that emit light according to image data. The controller is configured to control a driving voltage for driving the light emitting elements based on the number of light emitting elements detected. The image forming unit is configured to form an image based on light emission of the light emitting elements according to the image data.

An image forming device includes an image forming unit, a fuser, a memory, and a control circuit. The image forming unit forms an image on a recording medium with a decolorable toner based on image data. The decolorable toner decolorizes at a first temperature and does not decolorize at a second temperature that is lower than the first temperature. The fuser has a plurality of regions extending in a direction orthogonal to a direction of conveyance of the recording medium. The fuser generates heat in each of the plurality of regions to fuse the image onto the recording medium. The memory stores a correspondence between the plurality of regions and positions of a plurality of areas positioned along a main scanning direction in the image data. The control circuit changes the correspondence based on a degree of color development or decolorization of the image.

There are provided an information processing apparatus, a control method, and a storage medium, which are capable of suppressing the occurrence of an unintended print result. To this end, multiple spot colors that can be designated are displayed on a spot color setting screen. User selects the color to be used as the spot color while visually checking the multiple spot colors that the user can designate.

In a case where image data for which brief spot color matching has been performed is stored by a BOX function, it is not possible to output the image data in correct color on a condition that the image data is transmitted to another device as it is. In a case where image data is stored by the BOX function, in a printer driver that generates PDL data therefor, a color matching method of type accompanied by the brief spot color matching is not allowed to be set.

A color management system for a printing system includes a color management service that controls quality control operations, such as calibration and quality checks, over a plurality of printing devices. The color management service generates a target print job having a quality control target made of color patches. The color management service also encodes metadata within the target print job using a control strip. The control strip encodes the metadata using different color patches and color intensities. The control strip is scanned at the printing device to decode the metadata and enable a user interface to complete the quality control operation.

A printing system is disclosed. The printing system includes at least one physical memory device to store calibration logic and one or more processors coupled with the at least one physical memory device to execute the calibration logic to perform uniformity compensation of a plurality of secondary colors printed by pel forming elements, each of the pel forming elements associated with one of a plurality of primary colors, including generating a uniformity compensated first primary color transfer function for each of the pel forming elements associated with a first primary color and a uniformity compensated second color transfer function for each of the pel forming elements associated with a second primary color, generating an updated uniformity compensated first primary color transfer function for each of the pel forming elements associated with the first primary color and a uniformity compensated third primary color transfer function for each of the pel forming elements associated with a third primary color and generating an updated uniformity compensated second primary color transfer function for each of the pel forming elements associated with the second primary color and an updated uniformity compensated third primary color transfer function for each of the pel forming elements associated with a third primary color.
