A new method for the determination of the surface impression on glossy surfaces
Pages: 43 - 49
The overall impression of a surface is an important criterion for a consumer and his decision to buy a glossy surface. Therefore, the development of a new method, which measures the overall impression of a glossy surface, was the main goal at the Kompetenzzentrum Holz GmbH. This new method, which is described here, includes the measurement of the reflexion of a light beam on a glossy surface and transformation of the reflexion into graphical information. Due to the deformation of the original light beam on the samples surface, the new parameter, the so called surface impression, can be calculated. With this new method it is possible to evaluate the surface impression in total, which also includes its structure. The high correlation with the carpenter view (R² = 0,95) demonstrates the agreement of this new objective method with the currently used subjective individual impression.
