Inventor: NUSSEL BARBARA
IPC: B41N3/00
Filed: 1992-06-22
Abstract: To remove hydrophobic particles from the surface of a hydrophilic printing plate, particularly when the printing plate is used in off set printing, an ionized reactive gas is conducted to the surface of the printing plate, and applied thereto, to cause the hydrophobic particles to form volatile reaction products, which are then removed by suction. The gas can be generated either in a burner, preferably supplied with an oxygen/hydrogen mixture, emitted from nozzles spaced between 10 to 50 mm from the printing plate, in which the printing plate and nozzle are relatively moved at a rate of about 20 mm/sec; or, alternatively, the ionized gas is generated in form of a plasma by a plasma generator, for example a magnetron, operating at 2.45 GHz, which plasma is conducted to the surface of the printing plate in a reaction chamber which is physically sealed with respect to the printing plate, so that the reaction with the hydrophobic particles can there occur. The reaction chamber is coupled to a high-vacuum pump, to maintain a vacuum in the order of about 0.5 mbar above the printing plate and within the reaction chamber.

IPC: B44B3/00
Filed: 1992-06-24
Abstract: ABSTRACT OF THE DISCLOSURE     An engraving method is switched from line engraving to dot engraving (or vice versa) at a boundary line at every horizontal scanning by generating and controlling switching signals by means of an engraving discrimination plate.  An engraving is performed while a sweeping operation is being performed in a direction (X direction) substantially parallel to a long side of a portion of a card requiring engraving.          Since the number of horizontal sweepings are reduced considerably in comparison with the conventional method, the time required for engraving can be shortened.  Since the number of vibrations of the engraving table, which are the biggest obstacle for achieving light weight, is reduced in accordance with the reduction in the number of the above-described horizontal sweepings, the engraving table can be produced more light in weight.  As a result, a higher speed of the movement of the engraving table can be achieved, thus making it possible to further shorten the time required for engraving.
