Abstract

Described herein is a device for monitoring and drying and/or curing process of a coating composition applied at least partially onto at least one surface of a substrate, the device including a movable skid that includes at least one substrate holding unit, at least one lamp, at least one pattern holder including a pattern, and at least one camera, where the substrate holding unit, lamp and pattern holder are positioned on the skid relative to each other such that the light of the lamp can illuminate the pattern of the pattern holder, and the illumination can be projected onto the surface of the substrate, which is held by the substrate holding unit, and where the camera is positioned on the skid relative to the substrate holding unit holding the substrate, such that the camera is capable of recording images of the light reflected off the surface of the substrate.
