Filed: 1980-04-22
Abstract: A stencil washing apparatus includes a high-pressure system capable of supplying liquid to a surface of the stencil 3 at a pressure of at least 50 kg/cm<2>. Conveniently the high pressure system includes a pair of spray devices (12b,13b) movable horizontally relative to the screen and providing at least one and preferably several pairs of nozzles (12b',13b') capable of supplying liquid to the front and rear surfaces of the screen. The nozzles of each pair lie generally in the same horizontal plane but offset laterally (longitudinally to the screen) with respect to one another so that as the spray devices are moved horizontally relative to the screen, the screen is carried to bend under the liquid pressure. In a method of washing ink from the stencil, washing liquid is supplied to the surface of the screen at a pressure of at least 50 kg/cm<2>. Preferably, an ink dissolving agent is first sprinkled onto the screen at low pressure e.g. by sprays 12a, 13a, and, after allowing a sufficient period of time for the ink to be dissolved, the high pressure washing liquid is supplied to remove the dissolving agent and ink dissolved therein. <IMAGE>
