The project focuses on the areas of oak wood furniture, parquet, coated sheets and project design. This target group is facing increasingly better informed customers increasingly stringent requirements around the aesthetics (color retention) with the technical requirements (functionality). This leads to a growing awareness among producers that they need to accumulate knowledge. This project's main goal is to acquire additional knowledge, manufacturers of measuring color. As a baseline we used the visual assessment of wood surfaces and the division into homogeneous color classes. In addition, measurements are also carried out with a spectrophotometer. The project is an online camera and developed an online handset that is able to classify wood surfaces in the same homogeneous groups as human observers. Then, also considers the impact of a completion system on the appearance of a wood surface, and the behavior of wood under the influence of light over time. Through artificial aging discoloration of wood surfaces will be evaluated over time, causing manufacturers better understand the discoloration behavior of their products (speed, intensity and stability of the discoloration). Specific factors of influence on the appeal of an oak surface (eg. The influence of the exposure, size of the "mirrors") are directed studied in case studies. The case studies show a broadening increased from the scope.
