Abstract

A method for matching a vehicle coating comprising a basecoat and a clearcoat comprising: providing a database including a plurality of records for different basecoats, each comprising for a combination of one basecoat with a reference clearcoat having a reference gloss value i) a set of reflectance spectra for a plurality of aspecular angles, and ii) data representative of a paint formulation corresponding to the basecoat; measuring a gloss value and a set of reflectance spectra of the vehicle coating to obtain a measured gloss value and a measured set of reflectance spectra; correcting the measured set of reflectance spectra to obtain a corrected set of reflectance spectra by using gloss correction parameters based on the measured gloss value and the reference gloss value; selecting a candidate basecoat closest matching the corrected reflectance spectra; and obtaining from the database a paint formulation corresponding to the selected candidate basecoat.
