Abstract

By varying the voltage for forming an arc, metal paper 1, whose maximum roughness peaks 2 have a spacing of - 1/10th of the electrode 3 diameter, permits generating dots extending from the region of the eroded roughness peak (minimum dots 4) to the electrode region (relatively large dots). During minimum dot generation, the dots are positioned in the center rather than on the periphery of the electrode region, as is the case with smooth metal papers, thus leading to a higher resolution of the recorded images.
