Abstract:
Apparatus for engraving a gravure printing cylinder includes a setup circuit enabling direct dimensional control of the cavities engraved by a stylus. Controls are provided for setting a black cell width, a black channel width and a highlight cell width. These parameters are fed to the setup circuit which translates them into multiplication factors for an AC signal and a video signal. The multiplied signals are combined with an offset signal to produce a driving signal for the stylus.
