Abstract
A printing master 12 is described which includes a printing element and a base 33, characterized in that base 33 is provided with one or more strain gauges 31 and electric connections for measuring electric resistance. In a preferred embodiment, the printing element is a plate having a printing surface 35, of which the back side 37 is laminated to base 33. The printing master 12 may have an optional adhesive layer 36 and/or protective layer 32. The registration of the printing master can be adjusted conveniently and accurately by measuring the resistance of the strain gauges.
