USPTO Abstract

A method for deriving a calculation equation for accurately calculating an irregularity of a coating film by using data on the surface of the object coating film and a color value of the coating film and a method for digitizing a coating film irregularity by using the coating film irregularity calculation equation derived from the deriving method. The coating film irregularity calculation equation is derived by fabricating a coated sheet for deriving the calculation equation and evaluating the coating (S10), calculating a value in substitution for the degree of sparkle (S11), measuring a color value (S12), and deriving the calculation equation (S13). The calculation (S11) of the value in substitution for the degree of sparkle includes image capture (S11a1) and image processing (S11a2). The measurement (S12) of the color value includes colorimetry (S121) and calculation (S122) of color values.
