In accordance with an embodiment, an image processing apparatus comprises a scanner; a designation section configured to designate a color presented in an original document as the object to be removed; extraction section configured to extract color information of the color to be removed based on image data which is obtained by reading, using the scanner, a color information extraction sheet on which an image is formed with a material of the color to be removed; and a conversion section configured to form, based on the designation of the designation section and the color information extracted by the extraction section, an image by removing the image data in the color designated to be removed from the image data of the original document.

A combination of a latent-image pattern which forms a latent-image part and a background pattern that forms a background-image part is determined so that the latent-image part and background-image part have equal print densities. The determined latent-image pattern and background pattern, color information used to determine a color of the copy-forgery-inhibited pattern image, input image information as an image to be processed, copy-forgery-inhibited pattern basic information used to designate the latent-image part and background-image part, and camouflage region designation image information used to designate a camouflage region are input. A copy-forgery-inhibited pattern image is generated on the basis of the input information.

An image processing method is provided. The image processing method includes: converting a color reproduction target of an input image according to a color gamut of a target display device; generating a file of the input image of which the color reproduction target is converted; and storing the file of the input image.

A color patch generation apparatus includes a printing unit that prints color patches for first color space acquisition in a certain region of a plurality of sheets of paper by a certain number of patches and in a certain patch size, and prints color patches for second color space acquisition in a region different from the certain region of at least one of the plurality of sheets of paper by a certain number of patches and in a patch size smaller than the certain patch size.

Method, system, and graphical user interface for enabling optimal colorant job programming. A graphical user interface displays a plurality of gamut mode selectable features. One or more of the gamut mode selectable features can be selected for image processing of an image. A graphical image can be displayed within the next of the user interface based on image processing of the image, and in response to selection of a gamut mode selectable feature. The resulting displayed graphical image with the user interface can demonstrate to a user the benefit of utilizing additional colorant on the image particular pixels in the graphical image, which can benefit from the additional colorant.

In one embodiment, an image forming apparatus forms an image on a recording medium using a plurality of decolorable coloring materials having different decoloring conditions. Further, the image forming apparatus forms a mark relating to authority information indicating authority capable of decoloring one of the plurality of decolorable coloring materials for each of the decolorable coloring materials on the recording medium. Further, in another embodiment, a decoloring apparatus grasps the authority information, and decolors the image of the decolorable coloring material, in accordance with the grasped authority information.

A color processing device includes a color data acquisition section and a first-relationship generation section. The color data acquisition section acquires color data of a first image output by a first image forming device on a basis of image data. The first-relationship generation section generates a first relationship that is a relationship between the image data and the acquired color data, the first relationship being generated by applying the image data and the acquired color data to at least one first relationship candidate prepared in advance in a color gamut wider than a color gamut of the color data and by performing matching on the image data and the acquired color data with the first relationship candidate.

A printing system is disclosed. The printing system includes a halftone calibration module to receive one or more un-calibrated halftones, transform un-calibrated threshold values in the one or more un-calibrated halftones via an inverse transfer function to generate calibrated halftone threshold values and generate one or more calibrated halftones based on the calibrated halftone threshold values.

Systems and methods for providing remote approval of an image for printing are provided. One system includes a processing circuit in communication with an image capturing device that is configured to capture an image of a printed product. The processing circuit is configured to process the captured image into a processed image accurate to within a tolerance in a color space to indicate the visual appearance of one or more colors. The color space is a standardized color space, such as sRGB or CIELAB. The processing circuit is further configured to transmit the processed image to a display located remote from the image capturing device and to receive an input signal from a remote input device to allow a user to approve or reject the displayed processed image for printing on a print device.

An image forming apparatus 1 includes: a conveyance unit 40 that conveys a medium; a reading unit 50 that reads an image formed on the medium conveyed by the conveyance unit; a storage unit that stores data for specifying a color indicated by a reading result obtained from the reading unit 50; and a correction unit that corrects the data to match a color of the image and the color indicated by the reading result. The conveyance unit 40 conveys a color sample medium. Sa as a medium containing an image of a color region of a predetermined color, the reading unit 50 reads the image of the color region, and the correction unit corrects the data associated with the predetermined color in accordance with a reading result of the image of the color region obtained from the reading unit 50.
