<p>A printing method is provided which comprises generating pressure pulses at different points on an ink film applied onto the surface of a continuous plane sheet. This is done by focusing a light beam from a quantum generator at said points from the opposite surface of the sheet. The pressure pulses are generated either by an opto-hydraulic effect on the edge of the surface of the sheet, which is made of transparent material and onto which the ink film is applied, or by conversion of the light radiation into acoustic radiation while the quantum generator light beam is absorbed by the material, which is transparent to the wavelength of said beam. The printing device comprises a light beam deflection system on the surface of the sheet to create pressure pulses on the ink film at points defined by a program.</p> |
