Abstract
An inkjet head ejection performance evaluation method includes: printing a test pattern for examining an ejection condition for each nozzle by an inkjet head and reading the test pattern by an image reading device; 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.
