  • Patent number: 11161357
    Abstract: An information processing apparatus includes an acquisition unit, a decision unit, a determination unit, and a change unit. The acquisition unit acquires a measurement result regarding a printing medium characteristic value. The decision unit decides a candidate for a printing medium type based on the acquired measurement result, and a reference characteristic value of each of printing media types set in advance to identify a type of the measured printing medium. Information associated with the printing medium type to be printed is input. The determination unit determines whether to change the reference characteristic value of the printing medium type associated with the input information based on the measurement result and the printing medium type associated with the input information. Wherein, when the determination unit determines to change the reference characteristic value, the change unit changes the reference characteristic value of the printing medium type based on the measurement result.

  • Patent number: 11141999
    Abstract: While moving an ejecting unit, first patterns and second patterns are formed in a first direction on a medium. Third patterns corresponding to the first patterns are formed while changing a shifted amount by which the third patterns is shifted from the first patterns by a first shift amount in the second direction. Fourth patterns corresponding to the second patterns are formed while changing a shifted amount by which the fourth patterns is shifted from the second patterns by a first shift amount in the second direction. In a rough adjustment pattern, image density of a pair of patterns, which are formed of the first pattern and the corresponding third pattern, changes in the first direction in a first cycle. In a fine adjustment pattern, image density of a pair of patterns, which are formed of the second pattern and the corresponding fourth pattern, changes in a second cycle.

  • Patent number: 11124005
    Abstract: With a conventional method of estimating an application amount of a clear recording material from a color of a patch, it is difficult to realize high accuracy, similar colors are sometimes exhibited in measurement results even if there is a significant difference in the application amount of a clear ink. In contrast, with a disclosed configuration of estimating an application amount of a clear recording material from a reflection intensity of a patch, measurement results that exhibit a one-dimensional increase of a relationship between the application amount of the clear recording material and the reflection intensity are acquired, so that the accuracy of application amount estimation increases.
