Abstract: A color correction device includes: a color conversion unit configured to convert an input value in an input color space into an output value in an output color space; a selection unit configured to receive a selection, as a target color component, of one or more color components among a plurality of color components used in a printing device; and a correction unit configured to execute a first correction process of correcting, when the input value is a first type input value representing a color not including the target color component, a first type output value corresponding to the first type input value in a manner of reducing the target color component. The first correction process includes non-target-color component correction of reducing a color difference between before and after correction by correcting an output value component corresponding to a non-target-color component that is a color component other than the target color component among the plurality of color components.

Abstract: An image forming apparatus includes a print device, a first backend communication portion, a second backend communication portion, and an inquiry management portion. The inquiry management portion transmits, when determining that transmission of a permission response is possible, the permission response to a digital frontend via the first backend communication portion. The second backend communication portion receives print data from the digital frontend. The print device executes print processing that is based on the print data when the print data is received from the digital frontend by the second backend communication portion.

Abstract: A print image is acquired as first image data represented in a first color space used for forming an image on a first print medium. Second image data is acquired by performing, on the first image data, conversion into representation in a profile connection space using a first conversion table and white point conversion using the information on appearance in a redetermined observation environment, of a base color section where an image is not formed on the first print medium. The second image data is converted by using a second conversion table into converted image data represented in a second color space used for forming an image on a second print medium and an image corresponding to the print image is formed on the second print medium by using the converted image data.

Abstract: 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.

Abstract: There are provided a chart manufacturing apparatus, a chart manufacturing method, a program, and an image forming system that do not need to switch backgrounds in a case of measuring a chart using two types of backgrounds having colors different from each other. The chart manufacturing apparatus that forms, on a transparent substrate, a chart (102) measured by applying a first background color and a second background color, forms a first measurement background image (130) on a transparent substrate (100) using a coloring material corresponding to a first background color, forms a first patch group (122) including one or more first patches (126) using a coloring material of a first color at a position corresponding to the first measurement background image, and forms a second patch group (120) including one or more second patches (124) at a position where the first measurement background image is not formed.

Abstract: A textile printing system for digital printing of colored images onto typically colored fabrics, digitally using print nozzles or other digital means, the nozzles printing print pixels onto the fabrics. The system comprises a print file defining pixel colors for the individual printing pixels; and a deletion unit which deletes print pixels from the print file wherever a respective pixel color is within a threshold distance of the fabric color. The textile printer then prints the print pixels onto the fabric to form a colored image without printing any of the deleted pixels.

Abstract: An object is to perform both quality maintenance of a printed material and suppression of a reduction in productivity of a printing apparatus by performing density correction processing at appropriate timing that takes into consideration the state of the printing apparatus. The above-described object is implemented by accumulating inspection results of printed sheets that are output from the printing apparatus and causing the printing apparatus to perform density correction processing in a case where a color defect in which a destination color is not reproduced occurs successively a predetermined number of times or more at positions at which the color defect does not overlap another defect.
