Claim Text:
1. A flake prediction device for predicting amount of coarse flakes in a target coating composition, comprising: a test substrate mounted on a driver that is mounted on a support frame; a vessel positioned adjacent to said test substrate such that a S0 coating composition when poured in said vessel can be dispensed as a L0 layer of substantially uniform thickness on a surface of said test substrate through an opening provided on said vessel, the S0 coating composition comprising F0 parts by weight of said coarse flakes based on 100 parts by weight of said S0 coating composition; an optical measurement mechanism for projecting on said L0 layer a beam of light of a preset intensity at a preset angle of incidence from a light source; an optical measurement instrument to measure B0 flop of said beam reflected from said L0 layer at a preset angle of reflectance; a computer configured to:
