ABSTRACT:
Electronic apparatus for imprinting screen-process printing stencils, comprising: an electronic device for the color acquisition of the image of a color design so as to obtain information in a digital format which can be stored on a magnetic support; a computer for the management of the data stored on the magnetic support, suitable for allowing to manage the data, i.e. to select the fundamental colors, change them or superimpose them, with simultaneous on-screen display or printout on paper or the like; a computer which is controlled by the management computer and has the functions of controlling the data output by the management computer and of preparing the image for being imprinted; at least one microprocessor-based device with driving and synchronizing functions, which is suitable for translating the data output by the control computer into electric signals which are synchronized with a mirror scanning system for orientating the beam of the LASER onto the support to be imprinted and for modulating the intensity of the beam according to the position assumed thereby on the plane of the support to be imprinted; and a scanning system composed of at least one mirror which can be orientated by means of a galvanometer controlled by the control computer.
