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: Certain examples described herein relate to generating a Neugebauer Primary area coverage (NPac) vector. In certain cases, an operating state of a printing system is determined. A first NPac vector is obtained, having an initial set of Neugebauer Primaries (NPs). The initial set of NPs comprise a NP that is not implementable with the operating state. A target set of NPs is determined on the basis of the operating state, the target set of NPs being implementable with the operating state. A second NPac vector is generated, the second NPac vector having the target set of NPs.

Abstract: The present disclosure relates to a process for printing comprising the steps of selecting eight or fewer process colors from a known process ink color set, providing a color channel for the selected process colors from the known process ink color set, providing two or more spot color channels, wherein one or more of spot colors correspond to a non-selected process color of the process ink color set, applying a first ink limit and a first linearization to the one or more spot color channels to produce a color set including the non-selected process color of the known process ink color set, applying a second ink limit and a second linearization to the one or more spot color channels to produce a color set including the spot color, and optionally printing an image.

Abstract: The invention describes a graphic adaptation method for ceramic supports (PC_i), specifically tiles, adapted to receive a print, comprising the steps of (f0) loading an original image file (F_PRINT); (f1) printing a plurality of images on sample ceramic supports (PCS_j) starting from the original image file (F_PRINT); (f2) acquiring a sample image (IM_PCS_j) of the plurality of images printed on the sample ceramic supports (PCS_j); (f3) selecting sample points (P2) representative of the sample image (IM_PCS_j), and selecting original points (P1) present in the original image file (F_PRINT); (f4.1) matching in terms of points (M1) between the sample points (P2) representative of the sample image (IM_PCS_j), and original points (P1) present in the original image file (F_PRINT); (f5) modifying the original image file (F_PRINT) starting from the match in terms of points (M1), determining an adapted image file (F_ADAPT), thus adapting the graphics of the original image file (F_PRINT) to the graphics of the sample image (IM_PCS_j). The invention further describes a graphic adaptation system (100) for the implementation of the method described.

Abstract: 【課題】メタリック系やパール系の塗装であっても、光輝材や下地材の色の評価を分離して行うことができ、高い信頼性で塗装色を評価することができる塗装色評価装置および塗装色評価方法を提供する。 【解決手段】光源１１が、塗装面１に対して所定の角度でコリメート光を照射可能に設けられている。画像取得手段１２が、塗装面１上のコリメート光の照射位置に対し、３以上の複数の反射角度からのコリメート光の反射光による画像をそれぞれ取得可能に設けられている。色評価手段１３が、画像取得手段１２で取得された各画像について、所定の輝度よりも輝度が小さい低輝度領域と、輝度が大きい高輝度領域とに分けた後、低輝度領域の輝度の平均値と高輝度領域の輝度の平均値とを求め、求められた全ての画像の各平均値に基づいて、塗装面１の塗装色を評価するよう構成されている。

Abstract: The present application includes devices and methods for using corrective data for a reconstructed table. In some examples, a computing device can generate a key from a reconstructed table, determine corrective data for the reconstructed table based on the generated key, and implement the corrective data to the reconstructed table to generate an updated table.

Abstract: Certain examples described herein relate to smoothing a lookup table for an imaging system. The lookup table comprises entries to map elements in a first color space to corresponding elements in a second color space. In certain cases, the entries of the lookup table are classified into a plurality of classes, each of the plurality of classes being based on a color space characteristic in the first color space or the second color space. Each of the plurality of classes of entries is sequentially smoothed.

Abstract: A method is described. The method comprises determining a lightness coordinate value corresponding to a first color value along a black-white axis in an input device color space. A set of color values corresponding to the lightness coordinate value, in the input device color space is determined. A subset of the set, based on the respective angular positions of the color values in the set and an angular position of the first color value is determined. The method comprises deriving a set of print color space values of a target printing system comprising print color space values corresponding to the subset and a color value corresponding to the position of the lightness coordinate value, based on a predetermined association between input device color space values and print color space values. The method comprises determining a given print color space value corresponding to the first color value based on the derived set of print color space values.

Abstract: The present invention relates to a method of generating "expanded color chart" representing various ink combination, for profiling a multi-color printing device or printer, using "reduced set of color chart", printed using the printer, where a. The expanded color chart is computed by applying "Error Correction" function to the expanded color chart predicted using a theoretical model of color prediction for a given ink combinations in the expanded chart. b. Error Correction function is computed/modelled as function of the variance/difference observed between the color values predicted by the theoretical model and the actual values measured for the ink combinations in the printed "reduced set of color chart".
