An information processing apparatus, for use with an image forming apparatus including one or more mounting portions to which containers filled with color materials of different types respectively are mountable, includes a receiving unit that receives designation of pieces of color material information respectively indicating plural color materials selected by a user from the color materials with which the containers are to be filled respectively; an acquisition unit that acquires first image data indicating a first image; and a display unit that displays a second image using the color material information and the first image data.

A system and method for image testing is configured to apply at least one display property to a test image to generate a display modified test image and applying the at least one display property to a reference image to generate a display modified reference image. The system also applies a human eye model to the display modified test image to generate an eye modified test image and applies the human eye model to the display modified reference image to generate an eye modified reference image. The system may compare the eye modified test image with the eye modified reference image to determine human perceivable differences between the test image and the reference image.

An image editing apparatus includes a processor. Further, the image editing apparatus includes a memory having a set of instructions that when executed by the processor causes the image editing apparatus to generate a source image representation of a source image in a first color space. In addition, the image editing apparatus is caused to generate one or more source characteristic measurements based upon the source image representation. The image editing apparatus is also caused to generate a destination image representation of a destination image in a second color space. The destination image has a distinct structure from the source image. Further, the image editing apparatus is caused to transform one or more destination characteristic measurements of the destination image representation based upon the one or more destination characteristic measurements of the source image representation.

An information processing apparatus includes a display and a controller. The display displays an image. The controller controls the display to display a color setting section that sets information regarding a selected color selected from among multiple predetermined colors, and an effect presenting section that presents visual effect information representing a visual effect of the selected color.

There is provided a PC that performs print control on a printing apparatus which stores a plurality of pieces of color conversion information for color-converting first color information included in print data into second color information different from the first color information, the PC including a PC control unit that generates the print data including first designation information for designating in the print data a conversion target of the color conversion and second designation information for designating color conversion information used for the color conversion among the plurality of pieces of color conversion information stored in the printing apparatus, and transmits the generated print data to the printing apparatus.

A PC includes a first set information DB that stores a plurality of pieces of first set information including color conversion information for color-converting first color information into second color information different from the first color information and a print setting corresponding to the color conversion information in association with each other, and a PC control unit that obtains a designation print setting which is a print setting designated for print data, causes a PC display unit to display a color conversion list including one or more options of the color conversion information associated with the print setting corresponding to the obtained designation print setting based on the plurality of pieces of first set information stored in the first set information DB, and controls color conversion to be performed on the print data based on color conversion information selected from the color conversion list.

Techniques for interactively determining/visualizing the color content of a source image and how the corresponding image data is mapped to device colors are described herein. For example, the color content of a digital image can be converted between different color spaces to identify gamut limitations of an output device (e.g., a printing assembly), discover color(s) that cannot be accurately reproduced, etc. Color space conversions enable the transformation of the color content of the digital image from device-specific colorants to a device-independent representation (and vice versa). In some embodiments, these transformations are facilitated using lookup tables that are implemented in graphical processing unit-resident memory.

A method for inkjet printing machine color control includes color transformation of print data from first color space to process color space in a first stage using a computer transforming print data from the first to an intermediate color space while keeping special colors, and a second stage transforming corrected print data including special colors from intermediate to process color space. The computer uses print data corrected after the first stage as second stage starting values. Print data transformed into the process color space are printed. First color space corresponds to CMYK, flexographic printing or RGB color space with special colors, intermediate color space corresponds to CMYK color space with special colors, process color space corresponds to CMYK color space with additional process colors. The computer corrects CMY, not K print data or special not transformed colors, when correcting print data in the intermediate color space after the first stage.

The present invention relates to a printing system for producing a digital printed image, in particular on a textile, having a data server which is designed to receive image data of a print order, at least one printing apparatus with at least one digital print head, in particular an inkjet print head, which is designed to receive and print at least one print file for a print order, a first raster image processor module which is provided on the data server and designed to make available the received image data of the print order as a converted file format that can be read and processed in the form of a printed image by the printing apparatus, wherein the image data in the converted file format can be transmitted to the printer. The at least one printing apparatus is designed with a second raster image processor module, by means of which the image data in the converted file format can be adapted in a printer-specific manner prior to the printing of a corresponding printed image. The present invention further relates to a method for producing a digital printed image, in particular on a textile, in which image data for a print order are sent to a data server, by means of a first raster image processor module the sent image data are converted into a data format which can be read and processed in the form of a printed image by at least one printing device having at least one digital print head, in particular an inkjet print head, and in which the image data in the converted file format are transmitted to the printing apparatus. The converted image data transmitted to the printing apparatus are adapted in a printer-specific manner on the printing apparatus by means of a second raster image processor module prior to the printing of a corresponding printed image.

A method of printing a three-dimensional (3D) color object, layer-by-layer, comprises: obtaining a 3D CAD specification defining a 3D geometry and a surface color distribution for the color object to be printed, defining regions on a surface of the color object; defining colors for each region based on the CAD specification; determining, using the 3D geometry of the specification, conditions applying at respective regions that are liable to cause color variation, such that using the colors as defined at the respective regions may give rise to a coloration error; selecting color corrections defined for respective determined conditions; correcting the defined colors; and printing the 3D color object with the color corrections.
