In many industries, color stands for quality. Particularly in the case of consumer goods that reach the end customer, the exact color shade influences the value and identity of the product and the brand. Therefore, it is crucial to hit the right color tone in the production process and to produce it homogeneously across numerous batches. Color not only leaves an impression of quality, but can also be used as an indirect variable to control the process. For example, color sensors are used to monitor adhesive beads, sort parts or determine active ingredients. In most cases, color sensors are the more cost-effective solution because they offer higher precision than conventional switching sensors.
