Abstract:
1. A method for matching a repair paint to texture properties and colour properties of a paint film on a substrate to be repaired, the method comprising: imaging a texture of the paint film with a digital imaging device; analyzing the imaged texture using image analysis software; calculating texture data; and formulating the repair paint on the basis of concentrations of paint modules, wherein each paint module is associated to specified texture data and colour data, and wherein a calculational texture and colour model using the texture data and colour data of the paint modules is used to calculate a repair paint with matching texture and colour properties, and wherein a colour and texture difference formula is used that combines a colour difference formula and a texture difference formula with a weighing factor, wherein an optimum value for the weighing factor is determined specifically for each separate colour formula.
