1. A printed layer formation processing device adapted to perform a part of a process for forming a printed layer on at least a part of the print medium by a first colorant of a predetermined color in a molded object formation process including a step of deforming the print medium to obtain a molded object after the printed layer has been formed, the printed layer formation processing device comprising: a formation amount correspondence relationship storage part configured to store a formation amount correspondence relationship, which is a correspondence relationship between a degree of deformation of the print medium and a formation amount of the first colorant to be formed on the print medium, which are correlated so that a thickness of the printed layer is substantially the same in respective regions of the molded object; a deformation degree acquisition part configured to acquire the degree of deformation in the respective regions of the print medium; and a formation amount determining part configured to determine the formation amount of the first colorant in the respective regions of the print medium based on the degree of deformation acquired by the deformation degree acquisition part and the formation amount correspondence relationship.
