Abstract

A method for coating a flat substrate by a coater 1 comprising an entry station 11 for receiving the flat substrate 10 to be coated, a control system 14 for controlling print job data, print job settings and coater settings, an application module 12 comprising a supporting roller 26 for supporting the flat substrate 10 and an application roller 27 for transferring a layer of coating from a surface of the application roller 27 towards the flat substrate 10, an end station 13 for storing the flat substrate 10 when coated, and a first sensor 29 for determining a radius of the application roller 27. The application module 12 is configured to transport the flat substrate 10 from the entry station 11 in-between the supporting roller 26 and the application roller 27 towards the end station 13, wherein the method comprises the steps of a) the control system 14 receiving print job data and print job settings, b) the control system 14 determining a suitable impression of the application roller 27 by means of received print job settings, c) the first sensor 29 determining a radius of the application roller 27, d) determining an axis location of the application roller 27 having a distance of the radius 28 of the application roller 27 plus a nominal thickness of the flat substrate 10 read from the print job data minus the determined suitable impression from the supporting roller surface, e) automatically moving the application roller 27 to the determined axis location 273, and f) starting the transport of the flat substrate 10 from the entry station 11 in-between the supporting roller 26 and the application roller 27 towards the end station 13.
