Abstract: A method is described in which data representing a three-dimensional object to be printed is obtained. The data comprises object property data indicative of properties of the three-dimensional object. Layers within the three-dimensional object to be printed are identified. The obtained data is processed by comparing object property data associated with an identified layer to object property data associated with a reference layer selected from the identified layers. Where a difference in object property data associated with an identified layer and object property data associated with a reference layer is determined, the determined difference is stored.

Abstract: Certain methods of generating a color mapping are described. In one method, an output of a color halftone processing pipeline is processed so as to determine a set of Neugebauer Primary area coverage (NPac) values that are representative of the output of the color halftone processing pipeline. These NPac values are then used, together with knowledge of an original input image, to generating the color mapping.

Abstract: Methods for configuring and calibrating a printing system are described. Configuring a printing system involves obtaining data for determining a reference print element in the printing system. The reference print element is then used to determine calibration data for a given print element. The calibration data is applied for the given print element to generate a print output.

Abstract: Described herein are systems and methods for processing an image such as a halftone image. For example, in some embodiments, pixels of an image are checked to see if when printed would be represented by a given output. Pixels of the image that match defined values are replaced with pixels that are represented by a different set of outputs. This latter set of outputs may be selected to optimize one or more imaging attributes.

Abstract: Systems and methods for replacing cells of an image based on some pre-determined metric are described herein. For example, systems and methods described herein may improve the functioning of a standard imaging system. For example, the systems and methods described herein may be used to post-process existing images in an imaging system based on one or more pre-determined metrics and improve the halftone images according to those pre-determined metrics.

Abstract: 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.

Abstract: Certain examples described herein relate to structure forming for the production of a three-dimensional object. In these examples, different structure forming components or functions are applied to volumes of a three-dimensional object. These structure forming components or functions are arranged to differentially generate a halftone output. The halftone output is generated by processing a material volume coverage representation for the three-dimensional object. The halftone output is used to provide control data for instructing production of a three-dimensional object.

Abstract: Certain examples described herein provide a representation of a three-dimensional object for production of said object. These examples use a material volume coverage representation that is generated from received object data, such as a vector object representation. The material volume coverage representation includes material volume coverage vectors for at least volumes forming part of a raster representation of the three-dimensional object. The raster representation is generated from the vector representation. Each material volume coverage vector represents a probabilistic distribution of materials available to the apparatus for production of the three-dimensional object and combinations of said materials.

Abstract: A method of embedding data in a printed output having at least two-dimensions is described in which content data for the printed output and data to be embedded in the printed output are obtained. An input property value for a content element from the content data is determined. This is used to determine an output value for a probabilistic distribution of a set of output material compositions for a spatial element of the printed output, corresponding to the content element, based on the data to be embedded and the input property value.
