摘要： A profile adjustment method includes: accepting first input profile as a first component, accepting at least one of a second input profile and a spot color as a second component combined with the output profile, accepting a first target of adjustment values when color conversion is executed according to the first component and the output profile, accepting a second target of adjustment values when color conversion is executed according to the second component and the output profile, and adjusting the output profile based on the first and second targets. A first output profile may be accepted as the first component combined with the input profile and a second output profile may be accepted as the second component combined with the input profile.

摘要： In an example, a method includes receiving print data indicative of an image to be printed on a substrate. The print data may indicate an image portion in which an image is present and a void portion in which the image is absent. An amount of background print agent to be applied to a region of the substrate corresponding to the locations of the image portion and the void portion on the substrate when the image is printed may be determined. In examples, the amount of background print agent determined to be applied to a region of the substrate corresponding to the location of the void portion on the substrate when the image is printed is greater than the amount of a background print agent to be applied to the region of the substrate corresponding to the location of the image portion on the substrate when the image is printed.

摘要： An example system in accordance with an aspect of the present disclosure includes a halftone engine and a gray value engine. The halftone engine is to apply halftoning to an image recursively across a plurality of levels of image scales and spatial resolutions, to generate a pattern that is at least quasi-periodic across the plurality of levels. The gray value engine is to substitute gray values recursively for at least a portion of the halftoning.

摘要： There is a provided a liquid droplet discharging control device which causes a liquid droplet discharging apparatus including a head, in which a plurality of nozzles are arranged in a predetermined direction, to perform printing and which is capable of executing a nearby compensation process in which, on the basis of a dot position on which a predetermined nozzle for black ink forms a dot, a nearby nozzle that forms a dot in the vicinity of the dot forms a dot and executing a composite compensation process. The liquid droplet discharging control device includes a parameter acquiring unit that acquires parameters corresponding to the degree of liquid spreading toward a periphery after adhesion of a liquid droplet to a medium, and a compensation switching unit that switches between execution of the nearby compensation process and execution of the composite compensation process on the basis of the parameters.

摘要： In an image processing apparatus, an area separating unit classifies a property of a pixel in an image into any of plural properties that include at least a character property and an image property, a black generation and UCR processing unit performs a black generation process and a UCR process for the image, and a process amount specifying unit specifies a black generation amount and a UCR amount used in the black generation process and the UCR process to the black generation and UCR processing unit. Further, the process amount specifying unit sets the black generation amount and the UCR amount on the basis of a smallest color component value of a pixel with the image property using a conversion characteristic that varies in accordance with a lightness value, a chroma saturation value and a hue value of the pixel with the image property.

摘要： Provided is a color conversion table creation method for creating a color conversion table for an image forming apparatus which forms an image by performing, on an input color value with total use amount of color material exceeding set amount, a process for reducing the total use amount of color material, the table presenting correspondence between the input color value input to the image forming apparatus and an output color value in a device-independent color space. The method includes: acquiring an input color value of a patch image for creating the table; when the total use amount of color material defined by the acquired input color value is around the set amount, adjusting the input color value to have a smaller difference between the total use amount and the set amount; and creating the color conversion table using the patch image with the adjusted input color value.

摘要： The present invention provides an inkjet printing apparatus and an inkjet printing method for printing a high-definition image while improving glossiness of the image surface without causing complication and enlargement of the apparatus. A plurality of inks are ejected from first and second printing heads so that a weighted average of a printing rate for each scan regarding an ink having the highest lightness becomes the largest among the plurality of inks and so that a maximum value regarding the printing rate of the ink having the highest lightness becomes larger than those of other inks.
