Guide for Reliable Gloss Data

Uniform and consistent gloss are an essential quality criterion for a variety of products. Therefore, gloss needs to be objectively measured. Only what can be objectively measured, can be controlled and can be optimized which is of importance in product development as well as in production control. Especially in case of multi-component products a uniform gloss is an expression of "high quality". Variations in gloss look like something is wrong and the end-user will perceive it as a defect. Therefore, gloss limits and tolerances are defined based on application and customer expectations.
