A world without color and shine, wouldn’t this be boring? Decorative coatings can be encountered every day and everywhere: on furniture, building facades, bridges and refrigerators. Even “White Goods” are no longer necessarily white, but exhibit fascinating color looks – from very elegant stainless steel to metallic effects on to colorful, glossy or textured surfaces.
Coatings are fascinating. Not much thicker than a human hair, they combine a variety of functions. Besides the requirement to look perfect under different lighting conditions, they are also expected to retain their good look over a long time and even when being exposed to harsh environments. A multitude of color shades are available to offer the right nuance for every taste. The challenge is to find a precise measurement procedure to replace individual perception and personal experience with objective numbers.
Consistent color and appearance are crucial before as well as after sale. The visual impression during the first ten seconds will establish our perceptual quality opinion and be the driving factor in our purchasing decision. Uniformity, which is also called harmony for products consisting of several components, is also important. This is of particular importance when parts are manufactured in different production sites or are made by different suppliers.
Visual color perception is influenced by our individual color preferences, which are dependent on personal factors (mood, age, gender etc.), environment (lighting, surrounding etc.) as well as our deficiency to communicate color and color differences. A color looks different in the department store (cool white fluorescent lighting) than at home (warm, incandescent lighting). Effect colors will even change their appearance depending on the type of daylight conditions being sunny or cloudy. In order to guarantee consistent color and appearance under all possible situations, it is essential to define numerical parameters with customer relevant tolerances, which can be controlled in daily production and communicated among the entire supply chain of raw material and final product suppliers. A high quality production process should only be based on figures and facts and not emotions.
