Claim:
A printing method for forming a plurality of correction patterns on a medium, comprising the steps of: preparing said medium onto which said correction patterns are to be formed; and forming a plurality of correction patterns on said medium, each correction pattern having each of a pre-carry pattern and a post-carry pattern that has been formed adjacent to said pre-carry pattern in a carrying direction, said pre-carry pattern being formed on said medium by ejecting ink from a plurality of nozzles, said post-carry pattern being formed on said medium by ejecting ink from a plurality of nozzles in a downstream side in said carrying direction than said nozzles that have formed said pre-carry pattern, after said medium that has been formed with said pre-carry pattern has been carried in said carrying direction, wherein (A) said plurality of correction patterns are formed on said medium lined up in a direction that intersects the carrying direction by said plurality of said pre-carry patterns in said plurality of said correction patterns being formed by ink being ejected while said plurality of nozzles are moved once in said moving direction, and said plurality of post-carry patterns in said plurality of said correction patterns being formed by alternately repeating a plurality of times ejecting ink while said plurality of nozzles are moving in said moving direction and carrying said medium by said carrying unit, and (B) said plurality of correction patterns, in which a spacing between said pre-carry pattern and said post-carry pattern changes in a stepwise manner in increments of a spacing shorter than a carry amount, are formed, by said medium being carried in said carrying direction with said carry amount shorter than a nozzle pitch of said plurality of nozzles and by said nozzles that are used to form said post-carry pattern being changed.
