Abstract :
The half-tone printing process is outlined, and the means of achieving it electronically on plastic plates is described. The paper refers mainly to an equipment which effects the engraving by means of a hot cutting tool, using helical scanning, but brief mention is also made of a similar equipment using a cold tool, and an oscillating flat bed. Electronic devices for tone correction, reproduction of coloured copy, and enlargement and reduction are also described.
