    (54) Transfer molding on skin


    (57) The invention foresees on the skin a water repellent tanning which excludes the possibility of sorption inks on both sides of the skin coat. Then it is attuated the transfer phase of the inks, which form the drawing, from the sublimatic paper on the printing part acting with pressure and hot by means of transfer devices or other. The sublimatic inks initially penetrate into the tanned support, thus determines a new type of integrated printing which allows the drawing to during in the time and allows the inks penetration. This enables to avoid the degrading of the image even in case of abrasions.


    Description


    [0001] The invention refers to a transfer molding on skin of inks, forming the drawing on sublimatic paper, to carry out by means of a particular preliminary - tanning treatment of the skin cover. At present it is not allowed to reach satisfactory results in the transfer molding of the skin, since this porous material absorbs the sublimatic inks, thus leading to the progressive fading of the printing image.

    [0002] The invention allows the solution of the problem by adopting a preliminary treatment, before the printing phase, of the skin coat which enables to obviate this inconvenience. Substan­tially the methodology according the invention foresees on the skin a water repellent tanning which excludes the possibili­ty of sorption inks on both sides of the skin coat. Then it is attuated the transfer phase of the inks, which form the image, from the sublimatic paper on the part to be printed, acting with pressure and hot by means of transfer devices or other. The sublimatic inks initially penetrate into the tanned support, thus determins a new type of integrated printing which allows the image to during in the time and allows the inks penetration into shim. This enables to avoid the degrading of the image even in case of abrasions.

    [0003] The methodology can be integrated in different ways with other known ones or with other means and known systems in connection with the use finalities and requirements.


    Claims

    1) Transfer molding on skin, characterized by the fact that that a water repellent tanning proceeding is foreseen on skin which excludes the possibility of sorption of transfer inks on both sides of the skin coat. The inks forming the drawing are then transferred form the sublimatic paper on the part to print acting with pressure and hot by means of transfer machines or other. The sublimatic inks at first penetrate the wall of the tanned support thus determining a new type of printing which allows the drawing to persist and the inks penetration in the shim. This enables to avoid the degrading of the drawing even in case of abrasion.
