Imprint apparatus and article manufacturing method

An imprint apparatus that brings an imprint material on a substrate including a first mark into contact with a mold including a second mark and cures the imprint material, thereby forming a cured product of the imprint material on the substrate, comprising:

• a plurality of detectors configured to detect a relative position between the first mark and the second mark;
• and
• a controller configured to:
• obtain a plurality of pieces of relative position information corresponding to the plurality of detectors by detecting the relative position between the first mark and the second mark a plurality of times using the plurality of detectors in a state in which the imprint material is cured and a positional relationship between the substrate and the mold is maintained;
• and
• calibrate, based on the plurality of pieces of relative position information, the plurality of detectors by using a piece of relative position information of a first detector of the plurality of detectors as a reference and correcting other pieces of relative position information of other detectors of the plurality of detectors by adding offset values to the other pieces of relative position information to match the reference.
