  • Publication number: 20210056367
    Abstract: Certain examples described herein relate to mapping between an input color space and an output color space. In some cases, data representing a set of candidate output color values in the output color space is obtained for a transition region between two input color values in the input color space. A sub-region of the transition region is defined, the sub-region being associated with a target colorimetry and a target value of a metric. An output color value is selected from the set of candidate output color values. The output value has an associated value of the metric and an associated colorimetry. The selecting is based on the associated colorimetry and the target colorimetry, and the value of the metric and the target value of the metric. In some cases, mapping data is generated by assigning the selected output color value to the sub-region.

  • Publication number: 20210055896
    Abstract: An apparatus comprises a counter to determine a number of impressions already printed by a component in a printing device; and a controller, coupled to the counter, to use the number of impressions already printed and information relating to lifespan performance of the component in a printing device, to determine an estimated number of remaining impressions for the component, and to communicate the estimated number of remaining impressions to a user. The information relating to lifespan performance provides an indication of an estimated number of remaining impressions, for the number of impressions already printed, derived from statistical lifespan data selected in dependence on a lifespan threshold corresponding to the number of impressions already printed.
