  • Method and device for regulating the water-ink equilibrium on an offset plate of an offset machine
    Patent number: 5249036
    Abstract: A method is provided for controlling a water-ink equilibrium on a moving offset plate 2 in an offset copying machine wherein the offset plate is fixed to a rotating cylinder 1. The method includes the step of illuminating a predetermined area 35 of the moving offset plate 2, the density of which is known, with a coherent light source 30 under normal incidence. A portion of the light reflected around an axis perpendicular to the plane of the illuminated area 35 is collected in the focal plane of a convergent optical system 32. The intensity of the collected light is measured at at least one location in the focal plane of the convergent optical system.
