Fluorescent coating

The coating is usually applied with a coating-machine by means of an air-blade. This thin layer of coating is distributed over the support thus covering and ‘closing’ the surface of the paper.  The main advantage of the coating is that it makes the surface of the paper smooth and perfectly suitable for printing. This feature becomes a security element when the composition of the coating is made up of raw materials that are invisible to the naked eye but only by means of UV or IR rays.
