摘要： A test pattern formation method includes preparing a first pattern including a plurality of dot rows that are separated, and a second pattern including a plurality of regions having a width greater than a width of the plurality of dot rows and provided spaced apart by a plurality of gaps greater than or equal to the width of the plurality of dot rows. At least a portion of the first pattern and at least a portion of the second pattern are in positions overlapping each other. Given a largest overlap between one of the plurality of dot rows and one of the plurality of gaps as a reference, the other dot rows of the plurality of dot rows and the plurality of regions having a wide width overlap and are deviated from each other incrementally by a respective distance corresponding to a landing deviation amount.
