Abstract
A method including acquiring a first deviation value of ink landing positions in each position in a first range from a first pattern printed over the first range of a recording sheet in a scanning direction at a first moving velocity of an inkjet head, acquiring variation information representing a variation in the scanning direction of the first deviation value, acquiring from the variation information a first representative value representing the first deviation value in the first range, acquiring a second deviation value from a second pattern printed over a second range included in the first range at a second moving velocity of the inkjet head, acquiring a second representative value representing a deviation value in the first range at the second moving velocity, based on the second deviation value and a difference between the first representative value and the first deviation value in the second range.
