Abstract (en)

[origin: WO2008024295A2] The invention relates to a method for color matching a reference color formulation to a defined color shade standard. The method comprises the steps 1. Measuring the reflectance spectrum R<SUB>ST</SUB> of a color shade standard, 2. Mixing a paint according to a recipe for the color shade standard and applying the paint to a substrate, 3. Measuring the reflectance spectrum R<SUB>PT</SUB> of the applied paint, 4. Recalculating the theoretical reflectance spectrum R<SUB>RPT</SUB> for the recipe of the applied paint, 5. Calculating the difference spectrum ?R between the measured reflectance spectrum R<SUB>PT</SUB> of the applied paint and the recalculated reflectance spectrum R<SUB>RPT</SUB>, 6. Adjusting the reflectance spectrum R<SUB>ST</SUB> of the color shade standard with the difference spectrum ?R, 7. Calculating a recipe on basis of the modified reflectance spectrum R<SUB>STM</SUB>, 8. Mixing a aint accordin to the reci e and a l in the aint to a substrate.
