摘要： An image processing device in which a display section is caused to display a preview image for printing. The image processing device includes a processing section configured to generate the preview image obtained by converting raster image data of each of ink colors of color inks or special color inks into an RGB bitmap format, and a display controller configured to cause the display section to display the generated preview.

摘要： A method is disclosed. According to some examples, the method comprises determining, by processing circuitry, a first element set to be associated with a print addressable location, the first element set comprising a first plurality of elements, wherein each element of the first plurality of elements identifies a print colorant or print colorant combination and is associated with a probability that the print colorant or print colorant combination identified by that element is to be applied to the associated print addressable location. The method may comprise determining, by processing circuitry, a second element set to be associated with the print addressable location, the second element set comprising a second plurality of elements, wherein each element of the second plurality of elements identifies a print agent or print agent combination and is associated with a probability that the print agent or print agent combination identified by that element is to be applied to the associated print addressable location. The method may comprise determining, by processing circuitry, a combined element set based on the first element set and the second element set. An apparatus and a machine-readable medium are also disclosed.

摘要： Examples of a method and a system measure colorimetric data of a set of color samples deposited on a reference substrate and on at least one further substrate having distinct colors from one another. Based on the measured colorimetric data, estimate functions are applied for mapping between the colorimetric data of the color samples deposited on differently colored substrates.

摘要： A processor identifies a specific part composed of a plurality of significant pixels in a mixed-color test image. Furthermore, the processor identifies a color vector. The color vector represents a vector in a color space from one of a color of the specific part in the mixed-color test image and a color of a reference area including a periphery of the specific part to the other. Furthermore, the processor determines which of a plurality of image creating portions of an image forming device corresponding to a plurality of developing colors, is a cause of an image defect, based on the color vector identified from the mixed-color test image.

摘要： There are disclosed techniques for error diffusion for printing.
For example, there is disclosed a device comprising a pixel selector, to select a pixel from an image to be printed, wherein the pixel is associated to a group of device state probabilities, wherein each device state probability describes a probability of choosing a particular device state, wherein each device state describes the quantity of each colorant to be used in correspondence of the pixel.
The device may comprise a device state determiner, to choose the device state for the selected pixel on the basis of the device state probabilities associated to the selected pixel. The device may comprise a feedback chain, to diffuse device state probability errors to pixels to be subsequently selected. The feedback chain may include a selected pixel error determiner, to determine device state probability errors for each device state probability of the selected pixel. The feedback chain may include a neighbouring pixel selector, to choose neighbouring pixels among the pixels to be subsequently selected. The feedback chain may include a neighbouring pixel error modifier, to modify, for each neighbouring pixel, the determined device state probability errors according to criteria conditioned by metrics and/or classification data associated to the selected pixel and/or a group of previously selected pixels and the relative position between the neighbouring pixel and the selected pixel. The feedback chain may include an error diffuser, to diffuse the modified device state probability errors to the neighbouring pixels.-

摘要： A recording system for recording a recording image based on image data by repeating a pass operation in which a nozzle column discharges ink while reciprocating relatively to a recording medium in a main scanning direction to form dots on the recording medium, and a conveying operation of relatively moving the nozzle column and the recording medium in a sub-scanning direction crossing the main scanning direction, the recording system including an assigning section for obtaining a plurality of halftone data which is generated with respect to the same area of the image data based on the image data, and which corresponds to the ink of a predetermined color, and then assigning each of the halftone data obtained to the pass operations in the same direction in reciprocation in the main scanning direction in a predetermined recording area.

摘要： Certain examples described herein relate to a color processing apparatus and a method of generating configuration data for a color rendering device. The color rendering device operates based on color state instructions indicating output color states for portions of a rendered output. Render data may be generated by applying a halftone matrix and color data may indicate probability values for the output color states for input image areas corresponding to the portions of the rendered output. In described examples, configuration data defines an order of output color states for application of the halftone matrix. In the order, the output color states are grouped within the data based on color properties of a rendered output and an order within the clusters is based on colorant composition.

摘要： Certain examples described herein relate to generating a Neugebauer Primary area coverage (NPac) vector. In certain cases, an operating state of a printing system is determined. A first NPac vector is obtained, having an initial set of Neugebauer Primaries (NPs). The initial set of NPs comprise a NP that is not implementable with the operating state. A target set of NPs is determined on the basis of the operating state, the target set of NPs being implementable with the operating state. A second NPac vector is generated, the second NPac vector having the target set of NPs.

摘要： Methods and apparatus relating to substructures for three-dimensional objects are described. In an example, a processing apparatus includes: an interface to receive data representing a three-dimensional model object, the data including object model data and object property data; a mapping module to map received data to a print material coverage representation; a halftone module to provide halftone threshold data; and a substructure module to define a substructure for a three-dimensional object to be generated, the substructure specifying in at least a region thereof a consistent lattice structure and a variable material distribution. The apparatus is to apply a substructure and a halftoning to the print material coverage representation to generate control data for the production of a three-dimensional object having the substructure.

摘要： A plurality of halftone processing units are provided for processing each of a plurality of pieces of image data corresponding to a plurality of divided images to generate dot data representing presence or absence of dot formation. At least two halftone processing units simultaneously perform at least a part of halftone processing for at least two pieces of image data. In the halftone processing, complex error diffusion method processing of matching at least a part of dot data obtained by performing halftone processing using an error diffusion method for an error diffused gradation value of each pixel of a divided image with a determination result of a dither method, is performed.
