ABSTRACT:
To form a cellular surface layer in which the depth or shape of the cells is controllable, the layer is composed of a material which has a temperature-dependent shape retention memory, which is embossed or engraved, without material removal, on a carrier, such as a printing machine cylinder. The temperature of the layer is controlled during application of the embossing and, for example upon drop of temperature, it changes shape to a previously given shape. The depth, size, or presence of cells on the layer can thereby be controlled by controlling the layer temperature, for example by external heaters (9, 26) or by temperature controlling the carrier by a temperature controlled fluid circuit (38).
