767,007. Control fabrics. HEICHLINGER, H. Aug. 13, 1953 [Aug. 19, 1952; Dec. 24, 1952], No. 22348/53. Class 140. [Also in Groups XVI and XX] A flexible transparent material c for receiving impressions of printing formes for the purpose of producing copying patterns, particularly for offset and intaglio printing, has a coating of indiarubber or similar elastic material d and a further coating, e.g. of chalk, magnesia, talcum, titarated glass powder, or barium sulphate, to facilitate the acceptance of printing inks. When a type head a bearing ink b descends, the rubber material prevents spreading of the ink. The ink receptive coating can be entirely or partly removed, or made transparent after the printing operation. |
