An object of the present disclosure is to implement, at a low cost, highly accurate color calibration in a printing apparatus that performs printing using fluorescent ink. One embodiment of the present invention is an image processing apparatus that includes: a processing unit configured to perform processing relating to color calibration in a printing apparatus that prints an image on a printing medium using fluorescent printing material; and an execution unit configured to perform calibration processing of the printing apparatus based on a measured value that is obtained by measuring a patch chart for obtaining information on an amount of application of the fluorescent printing material in the printing apparatus, wherein a patch included in the patch chart is printed with the fluorescent printing material and subtractive color mixture printing material and at least one dot of the subtractive color mixture printing material covers a dot of the fluorescent printing material.

Image processing apparatus, image processing method, and storage medium

An image processing apparatus obtains image data that is defined as a first color gamut, transforms the image data into image data that is defined as a second color gamut, using color transformation information, and when, as a result of transformation, a first pair of color values included in the image data is transformed into a second pair of color values that have a color difference that is not perceived as different colors, generates second color transformation information such that the first pair of color values is transformed into a third pair of color values that have a color difference that is perceived as different colors as a result of transformation using the second color transformation information. A saturation difference of the third pair of color values is larger than a saturation difference of the second pair of color values.

Image processing apparatus, image processing method, and medium

Dot data for a boundary zone between metallic ink and color ink is changed to increase a time difference between a scan for applying the metallic ink and a scan for applying the color ink. With this change, a fusion time of the metallic ink is ensured, and the occurrence of an image defect is suppressed.

A printing apparatus comprises a decision unit configured to decide a ratio of ink application amounts of the fluorescent ink and the other ink respectively in each of the plurality of scans. The decision unit decides the ratio of the ink application amount of the fluorescent ink in each of the plurality of scans so that the amount of the coloring material of the fluorescent ink in a surface of an ink layer of the printing medium is less than the amount of the coloring material of the fluorescent ink in an inside of the ink layer of the printing medium.

Printing apparatus and printing method

When an image is recorded using an ink of a basic color and an ink of a specific color, if an amount of ink applied to a recording medium exceeds an amount receivable by the recording medium, the ink overflows and image quality deteriorates. At this time, ink overflowing can be prevented by reducing an application amount of ink, but color balance may vary. By preferentially reducing an application amount of the ink of the specific color among inks of a plurality of colors that are to be applied to a recording medium, a change in the color balance is suppressed and the ink overflowing is prevented.

A control method for controlling an information processing apparatus configured to generate print data using a first program that is interpreted and executed when operating in the information processing apparatus and a second program that is compiled in advance and is usable from the first program, includes acquiring a first generation logic for generating print data, the first generation logic being modifiable and linked with a printer configured to execute printing; generating a second generation logic by modifying the first generation logic at least partially; generating print data to be printed by the printer using input image data and the second generation logic; and transmitting, to the printer, the print data generated in the generating the print data.
