Abstract (en)
[origin: WO9426534A1] A process is disclosed for producing print rolls made of a metallic core cylinder and a plasma-sprayed copper or copper alloy coating which may be easily shaped by mechanical means into an only slightly rough, homogeneous closed surface into which high quality engravings may be incorporated. The process is characterised in that finely ground copper or a copper alloy powder with particles having a mean diameter of 12 mu m or less is applied by plasma spraying on the surface of the roll by means of a low power plasma torch, without oxidized intermediate layers.
