摘要： A test pattern is formed by selecting at least three parts from among parts for measuring an impact displacement due to print head displacement between first and second print heads, an impact displacement due to chip displacement between first and second chips, an impact displacement due to round-trip displacement between a forward pass and a reverse pass of main scanning, an impact displacement due to column displacement between first and second nozzle columns, an impact displacement due to position displacement of the first print head around a main scanning direction, and position displacement of the first print head, and an impact displacement due to position displacement of the first print head around a direction orthogonal to the main scanning direction and a direction intersecting with the main scanning direction. The test pattern has a length in a sub scanning direction less than that of the head. The at least three parts are arranged in the sub scanning direction.

摘要： Provided are an information processing device, an image printing apparatus and an information processing method with which it is possible to detect print head misregistration easily and with high precision. On the basis of imaging data for a test image comprising multiple first lines and multiple second lines respectively printed by first and second printing means, the information processing device specifies the relative positional relationship between first and second coordinate axes from the corresponding relationship between: first line printing coordinates on the first coordinate axis for which a first unit coordinate interval has been prescribed and second line printing coordinates, for which a second unit coordinate interval has been prescribed and which relate to the second coordinate axis for which a reference position, when the first printing means and the second printing means are disposed in a specified positional relationship, assumes a prescribed relative reference position relationship to a reference position of the first coordinate axis; and the first and second line printing positions in the imaging data. On the basis of said relative positional relationship and the prescribed relative reference position relationship, the information processing device calculates a value corresponding to the magnitude of misregistration of the second printing means from the specified positional relationship with respect to the first printing means.

摘要： An inkjet head ejection performance evaluation method includes: printing a test pattern for examining an ejection condition for each nozzle by an inkjet head (100) and reading the test pattern by an image reading device (58); measuring a first depositing position for each nozzle from a read image to calculate an angle deviation amount of the inkjet head based on the first depositing position and pattern information; calculating at least one of a second depositing position and second deposit displacement amount in which an influence due to angle deviation caused is eliminated; calculating a moving amount caused by rotation of the angle deviation amount from a reference position of the nozzle at a reference attaching angle up to a current nozzle position; and calculating, by using these calculation results, at least one of a distance between the adjacent pixels and a third deposit displacement amount including the influence.

摘要： A printer includes a page wide array of printing elements extending in a first orientation and co-located with a media path extending in a second orientation generally perpendicular to the first orientation. The printer is selectively operable according to a calibration involving current calibration values for a first subset of the page wide array of printing elements and a substitute calibration value for at least one non-first subset printing element of the page wide array immediately adjacent to at least one of the first subset printing elements.
