Patent ID: 8581142

Claim:
A method for transferring images to a wooden support by means of an apparatus provided with at least one source of a laser beam, means for focusing and moving the laser beam relative to the wooden support, as well as at least one adjustment unit for the emission of said laser beam, the method comprising the steps of: a. at least one of acquiring and creating an image to be transferred; b. converting information of the image into instructions for adjusting emission, movement and focusing of the laser beam relative to said wooden support; c. operating said moving and focusing means and said at least one adjustment unit according to said instructions to reproduce said image on said wooden support; d. said at least one adjustment unit adjusting the emission of said laser beam by directly varying at least one of (1) pumping of active material and (2) varying operation of a modulator placed within a resonant cavity of said at least one source of a laser beam; e. locally subjecting said wooden support to irradiation by means of said laser beam, with an energy per surface unit ranging from 0 j/cm2 to 43.7 j/cm2, in order to blacken the surface portion of said wooden support being subjected to said local irradiation; f. said instructions for adjusting the emission, movement, and focusing of the laser beam relative to said wooden support comprising penetrating said laser beam within said wooden support by a thickness ranging from 0.1 and 1 mm; and g. obtaining a reduced evaporation of water molecules contained in surface layers of said wooden support.
