Abstract: Examples relate to providing synchronized look-up table loading. In some examples, a print job is processed using an initial look-up table in processor memory. In response to the processing of the print job reaching a buffer trigger row of a portion of the print job, look-up metadata is accessed to locate a next look-up table. At this stage, the next look-up table is dynamically loaded into the processor memory as the processor continues to process the print job, where the processing of the print job begins using the next look-up table after a target row of the portion of the print job is reached.

Abstract: A method of calibrating a printing device, wherein the method comprises: associating a weighted printing value to each of a plurality of pixels, wherein associating a weighted printing value to each pixel comprises: obtaining, from a first calibration table, a first calibration value; obtaining, from a second calibration table, a second calibration value; obtaining first and second weighting factors, wherein the first weighting factor is obtained from a weighting table, generating the weighted printing value as the sum of the first calibration value weighted with the first weighting factor and the second calibration value weighted with the second weighting factor.

Abstract: Certain examples relate to converting between color spaces. A digital representation of an input color is pre-processed to convert the digital representation into a multidimensional node representing a region in the input color space and a set of adjustment values. The multidimensional node is mapped to a digital representation of an output color. The digital representation of the output color is adjusted using the set of adjustment values.
