Correction value determining method, correction value determining apparatus, and storage medium having program stored thereon
A correction value determining method of the present invention includes: causing a head to record a first pattern for confirming a transport amount of a medium, while transporting the medium in a transport direction relative to the head in accordance with a target transport amount, obtaining a first correction value that is associated with a relative position of the head and the medium based on the first pattern, the first correction value being a correction value for correcting the target transport amount during transport of the medium, causing the head to record a second pattern for confirming the transport amount of the medium, by transporting the medium while correcting the target transport amount using the first correction value associated with the relative position, obtaining a second correction value that is associated with the relative position of the head and the medium based on the second pattern, the second correction value being a correction value for correcting the target transport amount during transport of the medium, and determining a correction value of the target transport amount by making a use of the first correction value and the second correction value associated with the relative position when the medium reaches a roller provided on the downstream side of the head in the transport direction different from a use of the first correction value and the second correction value associated with the relative position at times other than when the medium reaches the roller.
