    Abstract: In an example, a virtual build volume comprising a representation of at least a part of an object to be generated in additive manufacturing is segmented into a plurality of nested segments comprising a core segment, an inner peripheral segment and an outer peripheral segment. Additive manufacturing control instructions may be generated for the nested segments. The control instructions for the core segment may provide a first region of the object corresponding to the core segment and having a first color. The control instructions for the outer peripheral segment may provide a second color for a second region of the object corresponding to the outer peripheral segment. The control instructions for the inner peripheral segment may provide a third color for a third region of the object corresponding to the inner peripheral segment, wherein a color of the third region is determined so as to at least partially visually mask the first region.

    Abstract: In an example, a method includes acquiring data representing an article to be printed. The data may include at least one element set associated with print addressable location(s) and comprising a first and second element. The elements each identify a print material or print material combination and is each associated with a probability that the print material or print material combination identified thereby is to be applied to the associated print addressable location. A halftone matrix may be acquired comprising threshold values of a first and second value range. The threshold values of the first and second value range are distributed according to a first and second distribution pattern respectively. The halftone matrix may be applied to the data to determine print instructions to distribute the print material or print material combination identified by the first and second element according to the first and second distribution patterns respectively.
