Method for Baking Coated Printing Plates

The invention relates to a method for burning in a coating of an aluminium or an aluminium alloy printing plate support, in the case of which the printing plate is heated to a burning in temperature, maintained at this temperature for a predefined duration and subsequently cooled. Deformations can b...

Beschreibung
Zusammenfassung:	The invention relates to a method for burning in a coating of an aluminium or an aluminium alloy printing plate support, in the case of which the printing plate is heated to a burning in temperature, maintained at this temperature for a predefined duration and subsequently cooled. Deformations can be minimised even further after the burning in process if at least in a temperature range between 150° C. and the burning in temperature, preferably 100° C. and the burning in temperature, the temperature differences of the metal temperature of the printing plate measured along a line in the longitudinal direction of the printing plate during the heating and cooling are maximum 40° C. over a length of 40 cm and the temperature differences of the metal temperature of the printing plate measured along a line perpendicular to the longitudinal direction are less than 10° C. during the heating and cooling.
