a processor configured to

obtain a geometric feature amount of a droplet of a material on a substrate, related to a spread of the droplet of the material on the substrate, based on an image of a first plurality of droplets of the material captured by an image capturing unit while the material and a template are in contact with each other to form the material in a forming condition,

obtain correspondence relationship data between forming conditions when the material and the template are in contact with each other to form the material and geometric feature amounts related to the spread of the droplet of the material on the substrate,
