In a process for providing a coating of different textures on a substrate comprising applying an ultraviolet light curable coating; increasing its viscosity and initiating texturing by exposure to ultraviolet light; maintaining in a dark space to complete texturing; and curing, the improvement comprising providing dark and light colored backgrounds, the former being absorbent to infrared red light and the latter being reflective to infrared red light, and, after increasing the viscosity, using infrared red light to decrease the viscosity over the dark background to a greater extent than the viscosity over the light background.
