Abstract: The method may comprise depositing print agent of a particular color onto a printable substrate to form a patch of print agent. It may comprise directing radiation from a plurality of radiation sources onto the patch of print agent and onto the printable substrate. Also, may comprise detecting, using a sensor, radiation from the plurality of radiation sources which has been reflected from the printable substrate and radiation from the plurality of radiation sources which has been reflected from the patch of print agent. Further, may comprise measuring, for each of the plurality of radiation sources, an intensity of the radiation reflected from the printable substrate and an intensity of the radiation reflected from the patch of print agent. Also, may comprise selecting, based on the measured intensities, a radiation source of the sources to be associated with the print agent of the particular color.

Abstract: The disclosure relates to a rendering apparatus, method and non-transitory machine-readable storage medium for determining a speed of a carriage during rendering of an image. A plurality of swaths of rendering fluid are deposited on a print target using a set of printheads moving across the print target. A temperature of a curing module is measured at a respective time of depositing each respective swath. An arrival time for each deposited swath to respectively arrive at the curing module is predicted. The speed of the carriage during depositing the plurality of swaths is determined based on the measured temperature of the curing module and predicted arrival time for each respective swath.
