1. An imprinting method comprising:
supplying an imprint material onto a substrate;
bringing a patterned portion of a mold into contact with the imprint material, which has been supplied onto the substrate in the supplying of the imprint material, to form a pattern on the imprint material in a predetermined pattern region on the substrate; and
increasing a viscosity of the imprint material at a predetermined position, which includes a position of a predetermined mark provided on the substrate, other than the predetermined pattern region to be higher than a viscosity of the imprint material in the predetermined pattern region after the supplying of the imprint material and before the bringing of the patterned portion into contact with the imprint material,
wherein the increasing of the viscosity is performed in a state in which the mold and the substrate do not face each other, and
wherein the increasing of the viscosity is performed before installation of the substrate in an imprint apparatus to perform the bringing of the patterned portion into contact with the imprint material.
