摘要： Apparatus and methods for transforming three dimensional object data are disclosed. In some examples, data representing a three dimensional object is received, the data comprising object property data indicative of at least one attribute of at least a portion of the three dimensional object. The object property data is transformed into a plurality of device independent object property data objects having a common data structure, each object property data object comprising a value indicative of each of a predetermined set of object properties.

摘要： Methods and apparatus for three-dimensional object representation are described. In an example, data representing a three-dimensional object is received, the data comprising an object property description associated with each of a plurality of locations within the object. Distinct object property descriptions are identified and a data object, which has a plurality of addresses, is populated with data indicative of the distinct object property descriptions, such that data indicative of each distinct object property description is represented at a different address. Data comprising a representation of the object is generated, the data comprising a data object address associated with each of a plurality of locations, wherein the data object address corresponds to the address of data indicative of the object property description for that location.

摘要： A method of color halftone processing is disclosed. A plurality of color mappings each provide a mapping from a color value in a color space to a set of Neugebauer Primary area coverage (NPac) values in an NPac space. An imaging metric is obtained for each NPac value in the set. An NPac value in the set is selected based on the imaging metric. The selected NPac value is used as an output NPac value in a combined color mapping for the color value.

摘要： Methods and apparatus of determining a halftone scheme are described. In an example, data representing a three-dimensional object is obtained, the data comprising object model data representing the geometry of the three-dimensional object and object property data representing at least one object property of at least a portion of the object. It is determined if a halftone scheme dependent object property is specified by the object property data and a halftone scheme is determined. Data representing a portion of the object having a halftone scheme dependent object property is associated with a determined halftone scheme.

摘要： The application refers to a method for generating three-dimensional object models for an additive manufacturing process in a layer-by-layer manner, e.g. 3D-printing, and to generating control data for use by the print apparatus. The object models are generated from a geometric description and from object generation data, which comprise the print apparatus and attributes such as a halftone scheme, a print apparatus setting, an object structure and a print material coverage representation. The method is implemented in the form of a computer software product and generates data specific for each identifies printing device.

摘要： The present disclosure relates particularly but not exclusive to a method for printing in a multipass print mode using a first printhead (PT1) and a second printhead (PT2), the method including printing in a first pass a first image in a first area of a print medium using a first set (ST21) of nozzles (N5-N24) from the first printhead (PT1), printing in a second pass a coating layer over the first image using a second set (ST22) of nozzles (P4-P22) from the second printhead (PT2), and printing in a third pass a second image over the coating layer using a third set (ST23) of nozzles (N1-20) from the first printhead (PT1).

摘要： A method for color mapping is disclosed. A color mapping is generated based on an imaging model and a color model for an imaging device. The imaging model allows a set of perturbations to be modelled. A set of metamers is determined for one or more colors. For each metamer, at least the imaging model is used to estimate a color output with at least one modelled perturbation. The color outputs are used to select a metamer from the set to be used for the color mapping.

摘要： A printing system and method to process image data is disclosed. The printing system includes an identification module and image pipeline module include a linear threshold array algorithm and a halftoning algorithm to process the image data. An image pipeline module applies a linear threshold array algorithm to line regions and a halftoning algorithm to the non-line regions.
