Abstract: A system for presenting a soft-proof of a three-dimensional (3D) printed part may include a processor, and a memory device communicatively coupled to the processor. The system may also include a communication link to support communication with a 3D printing device, and computer usable program code to, when executed by the processor, retrieve data from the 3D printing device defining at least one capability of the 3D printing device that affects an appearance of a part when printed. The system may also include an application programming interface (API) to provide data defining generation of a soft-proof of the part based on the at least one capability of the 3D printing device, the soft-proof of the part depicting characteristics of the part as the part appears as printed.

Abstract: In some examples, with respect to three-dimensional printer color management, three-dimensional printer native space coordinates of a three-dimensional printer may be mapped to three-dimensional printer printing agent space coordinates of the three-dimensional printer. The three-dimensional printer printing agent space coordinates may be mapped to color space coordinates. The color space coordinates may be mapped to two-dimensional printer printing agent space coordinates of a two-dimensional printer. The two-dimensional printer printing agent space coordinates may be mapped to two-dimensional printer native space coordinates of the two-dimensional printer. A color management protocol of the two-dimensional printer may be utilized, based on the mapping of the three-dimensional printer native space coordinates to the two-dimensional printer native space coordinates, for the three-dimensional printer to print a three-dimensional object.

Abstract: Color values are measured for a set of color targets printed by a reference printing device on a medium of a reference media type. A different printing device prints a subset of the set of color targets on another medium of this reference media type. The color values of the subset of color targets printed by the different printing device are measured, and the different device calibrated based on the measured color values for both the set that the reference printing device printed and the subset that the different device printed. The different printing device can then also be calibrated for a different media type, based on a transformation of the set of color targets printed by the reference printing device on a medium of the different media type relative to the set of color targets printed by the reference device on the medium of the reference media type.

Abstract: An example system for thermal energy determination can include a first controller comprising a processor and a non-transitory machine-readable medium (MRM) communicatively coupled to the processor. The non-transitory MRM can include instructions executable by the processor to cause the processor to receive relative humidity information of an environment of a thermal printing device, determine a colormap to a print media of the thermal printing device based on the relative humidity, and determine a particular thermal energy to apply to the print media based on the determined colormap.
