Decorative member manufacturing apparatus and method for manufacturing decorative member

A method for manufacturing a decorative member having a decorative layer provided on a surface of a base material, the method comprising:

• a jetting step of jetting, by a jetting part, a fluid toward the surface of the base material, the fluid being cured by receiving light, wherein the jetting part comprises inkjet heads;
• and
• an irradiation step of irradiating, by a light emitting device, the fluid which has landed on respective portions with light, to form a cured convex portion constituting the decorative layer on the respective portions on the surface of the base material,
• wherein, in the jetting step, the jetting part is controlled by a controller based on control data for forming the cured convex portion having a set thickness in the respective portions, and
• correction processing is performed by a host computer on the control data, the correction processing being a process of reducing a thickness corresponding to a spatial frequency equal to or smaller than a set value, in a correspondence relationship between the thickness and spatial frequency of the cured convex portion which is formed in a case where the controller controls the jetting part based on the control data,
• wherein the correction processing is a process of weighting a thickness of the cured convex portion according to a spatial frequency corresponding thereto, and
• in the correction processing, a weight of less than 1 is given to the thickness of the cured convex portion corresponding to the spatial frequency equal to or smaller than the set value, and a weight equal to 1 is given to a thickness of the cured convex portion corresponding to a spatial frequency larger than the set value.
