Abstract:
A method for printing which comprises placing a carrier before a printing plate, applying a layer of ink onto the surface of the plate and selectively transferring the ink from predetermined points on the surface of the plate to the carrier, characterized in that the surface of the plate is continuous and smooth, the layer of ink is applied onto the surface facing the carrier, and from the side of the opposite surface a light beam from a laser is focused on the predetermined points of the layer of ink which are to be transferred onto the carrier so as to generate pressure pulses in the ink causing the ejection of a drop of the ink therefrom,wherein the printing plate is an electrically nonconductive material which is transparent for the wavelength radiated by the laser, andwherein a plurality of insulated areas of a material which is not transparent for the wavelength radiated by the laser are on the surface of the plate facing the carrier.
