Abstract: In one example in accordance with the present disclosure a three-dimensional illumination chart is described. The chart includes a substrate divided into a number of portions. Each portion includes a raised relief pattern disposed thereon having a relief angle relative to a reference line. Each relief angle of the raised relief patterns of the number of portions is different from other relief angles of other raised relief patterns of other of the number of portions.

Abstract: In one example, a method comprises receiving data representing a first property of a three-dimensional object generated by a print apparatus, the data having been determined by measurement of the object. A difference between the data representing a first property and predetermined data may be determined, and, based on the difference, an estimate of a second property of the object may be determined.

Abstract: A system including a memory to store instructions and initial color representations and a processor to execute the instructions in the memory to reference a database having a set of lexical color classifiers, transform each of at least a pair of initial color representations to color values associated with the set of lexical color classifiers, and generate a relative similarity measure related to the at least a pair of initial color representations based on the color values associated with the set of lexical color classifiers.
