Image data generation method, structure formation method, and structure formation apparatus

Abstract

A computer (10) generates image data of a density image to be printed on a print medium (M) including an expansion layer (M1) that expands by heating. First density image data for printing on one surface (FS) of the print medium (M) to expand the expansion layer (M1) is prepared first. The first density image data is then converted so that the density of a part of a target region having the same density included in a first density image (P1) represented by the first density image data is higher than the density of the other part of the target region, to generate third density image data.

Description

[0001] This application claims priority based on Japanese Patent Application No. 2016-000752 filed on January 5, 2016 and Japanese Patent Application No. 2016-232577 filed on November 30, 2016, the entire contents of which are incorporated into this application by reference middle. technical field [0002] The present invention relates to an image data generating method, a structure forming method, and a structure forming device. Background technique [0003] As one of the structure forming techniques, there is known a technique in which a desired pattern is printed on a medium to be printed including an expansion layer that expands due to heating with black ink or toner, and then, the pattern is printed on the medium to be printed. Apply light evenly. In this technology, the area printed with black ink or toner has a higher light absorption rate than the unprinted area, and the light absorbed by the black ink or toner is converted into heat. In the case where the area is ...

AI Technical Summary

Problems solved by technology

However, since the cross-sectional shape of the structure formed by the above-mentioned structure formation technology is relatively not sharp, there is a problem that it is difficult to perceive it through the sense of touch.
