Claim of US Patent No. 10,992,822

1. An apparatus for adjusting control parameters of a printing substance for a printing system in before a color calibration process, the apparatus comprising: at least one sensor in a tank for the printing substance, the tank connected to supply the printing substance for printing by the printing system;a transceiver to receive a measurement of a value of at least one control parameter from the least one sensor; and
a processor to:
compare the measured value with a predetermined threshold range of values of the at least one control parameter, wherein the predetermined threshold range is associated with an allowable deviance from an operational set point of the printing substance;
adjust the value of the at least one control parameter towards the set point value within the predetermined threshold range if the measured value is outside the predetermined threshold range; and
thereafter calibrate the color of the printing substance.
