ABSTRACT:
The present invention realizes a specular gloss simulation device which can accurately simulate specular glossiness of an image even if the image has a low density and low glossiness by measuring, in a given geometry, luminance of a sample having a base material and a colorant material layer formed on the base material and then simulating a specular reflection light amount in an other geometry from the measured luminance. A specular gloss simulation device is provided with a lower layer reflection light component calculating section for calculating a lower layer reflection light component, an internal reflection light component creating section for creating an internal reflection light component, a surface reflection light component creating section for creating a surface reflection light component, and a specular reflection light amount calculating section for obtaining a specular reflection light amount of the sample by adding up the components thus created by each section.
