    Abstract: A method of obtaining a calibration factor for color calibration of a printing system. The method includes printing, using the printing system, a plurality of Neugebauer primaries (NPs) each defined by a respective Neugebauer primary area coverage (NPac) vector. For each of the NPs, an area coverage change of the NP is determined from a measurement of a visual property for the NP and a measurement of the visual property for a corresponding reference NP corresponding to the respective NPac vector. The calibration N factor for the printing system is obtained based on the area coverage change for respective NPs of the plurality of NPs.

  • Patent number: 10836177
    Abstract: In a control device, a controller sets an order condition using a plurality of sets of timing information and a plurality of index values stored in a memory. The plurality of index values is acquired from a recording device under a condition where a first cartridge is mounted in the recording device. The order condition requires that one of a latest index value and a current timing have reached corresponding one of a reference index value and a reference timing, and is set so that a second cartridge is delivered to a predetermined destination at a first timing at which the first cartridge is expected to be out of a printing agent while a tank of the recording device is expected to still accommodate the printing agent. The controller transmits an order command instructing to order the second cartridge to a relevant device after the order condition is satisfied.
