    Abstract: An image forming apparatus includes a detection unit to detect a toner attached to an image carrying surface at a detection position. The first control unit controls the image forming unit such that a first check image including a patch pattern and a line pattern is formed. The relationship determination unit determines a correlation between a width of the line pattern and a density of an image to be formed based on a density of the patch pattern and a width of the line pattern. The determination unit determines an allowable range based on the determined correlation. The second control unit controls the image forming unit such that a second check image including the line pattern is formed. The line width determination unit determines a width of the line pattern based on a detection status relating to the line pattern. The monitoring unit monitors a formation status of the image by comparing the determined width and the determined allowable range.

  • Patent number: 11554591
    Abstract: An object is to enable highly accurate density unevenness correction while suppressing a reduction in productivity of printing accompanying correction value calculation for density unevenness correction. In the image processing apparatus, density correction information that specifies an output tone value for implementing a target density for an input tone value for each nozzle and which does not include the influence by a non-ejectable nozzle that cannot eject ink normally is acquired. In a case where a non-ejectable nozzle is detected during printing processing, output tone values corresponding to the detected non-ejectable nozzle and peripheral nozzles thereof among output tone values specified in the density correction information are changed.

    Abstract: First quantization data for printing by the first nozzle group and second quantization data for printing by the second nozzle group are generated based on multi-valued data. By use of mask patterns, first print data and second print data are generated based on the first quantization data and the second quantization data. The first mask pattern for generating first print data and the second mask pattern for generating second print data are formed so as to include a pixel in which printing of a dot is allowed in both and a pixel in which printing of a dot is not allowed in both. The pixel value of each pixel indicated by the multi-valued data has a correlation with the sum of the number of dots indicated by the first print data and the number of dots indicated by the second print data in the area corresponding to each pixel.

  • Patent number: 11397878
    Abstract: Certain examples described herein relate to printer calibration. In some cases, adjustment data is received, indicating an adjustment to be applied to a given colorant. A Neugebauer Primary area coverage (NPac) vector defining an operating set of Neugebauer Primaries (NPs) is obtained. Configuration data is determined, dependent on the operating set of NPs. The configuration data maps colorant adjustments to relationships between NPs in the operating set, for both an increase and a decrease in the given colorant. In some cases, the configuration data and the adjustment parameters are used to identify first and second subsets of the operating set of NPs. The NPac vector is adjusted by decreasing an area coverage of an NP in the first subset and complementarily increasing an area coverage of an NP in the second subset.

    Abstract: An inkjet printer includes: a print execution unit that executes printing; and a controller that controls the print execution unit. The controller is configured to: determine whether a type of ink supplied by the ink supply unit is changed; determine whether to use a residual ink which is ink before change remaining in the ink flow path in response to be determined that the type of the ink is changed; control the print execution unit to execute new printing using the residual ink in response to be determined to use the residual ink for the printing; and execute a discarding process for discarding the residual ink before the new printing is performed in response to be determined to not use the residual ink for the printing.
