Abstract: A method of forming on a flexible backing strip a decorative thermal-transfer film containing graphics defined by images and/or texts and by a progressive identification code (bar code, alphanumeric code, etc.) assigned to each graphic; the method providing for applying on the backing strip a first polymer film, on which the graphics are screen printed, and the respective progressive identification codes are thermographically printed; and a second polymer film is then applied on the first film, so that the graphics and associated identification codes are interposed and packed between the two polymer films to form the decorative film. The polymer films are made of polymer materials compatible with both the screen printing and thermographic printing inks and/or pigments used.

Abstract: The invention relates to a method for making a relief strip, comprising the steps of etching the strip, causing the etched strip to pass through a coloring line, a silicone solution metering unit, to meter a silicone solution on the strip etched portion, introducing the strip into a mold having a plurality of mold cavities of different cross-sections and spacings, therefrom a vacuum metered ink amount is ejected and caused to enter the recess of the material, and causing the strip to further pass through an infrared oven, and finally brushing the strip.
