Droplet deposition position error measurement method, droplet deposition position error adjustment method, droplet ejection control method, and image forming apparatus |
摘要 |
The droplet deposition position error measurement method, comprises the steps of: ejecting liquid droplets from a liquid ejection head including a plurality of liquid droplet ejection ports in such a manner that the liquid droplets are deposited on a recording medium; determining an amount of a droplet deposition position error with respect to an ideal droplet deposition position on a recording surface of the recording medium, according to a droplet deposition result obtained from the liquid droplets on the recording medium; separating a first error component caused by an error in a relative position between the liquid ejection head and the recording medium, and a second error component caused by an error in an ejection direction of each of the liquid droplet ejection ports, from the determined amount of the droplet deposition position error; and obtaining error information relating to at least one of the first and second error components.
