A method of duplicating texture and pattern of a natural material using a low temperature embossing process is provided. More particularly, in the method of duplicating texture and pattern of a natural material using a low temperature embossing process, a polymer resin having low glass transition temperature is coated on a surface of the natural material and then low temperature embossing process is performed thereon at a specific temperature and a specific pressure to duplicate a distinct texture and a fine pattern of the natural material as they are, thereby improving luxurious and aesthetic properties and achieving a large area and mass production, such that it may be applied to interior and exterior materials of a car, a case of a cellular phone and a laptop, home appliances, or the like.

There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface with a monolayer of particles, ii) treating the substrate surface to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate, the donor surface returns to the coating station where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.

A method for manufacturing structured press elements comprises at least the following steps: the step of providing an element of metal; the step of providing a mask on a surface of the element for shielding portions of the surface; the step of treating non-shielded portions of the surface of the element; the step of removing the mask; wherein the method comprises at least a step in which the surface of the element is subjected to an ultrasonic treatment and/or that the step of providing the mask comprises at least a treatment with infrared radiation and/or that the step of chemically treating is performed with the surface directed downward.

A stamping device includes a stamping data generator configured to create stamping data to form a stamp image on a surface of a processing target, a positioning data generator configured to create positioning data to position the processing target, and a controller configured or programmed to control an operation of the processing tool. The controller includes a first controller configured or programmed to control the processing tool such that stamping is performed, based on the positioning data at a first stamping energy, on the processing target including a protective sheet attached thereto in a predetermined area including a stamping area where the stamp image is to be formed, and a second controller configured or programmed to control the processing tool such that stamping is performed, based on the stamping data at a second stamping energy equal to or different from the first stamping energy, on the processing tool in a state of having the protective sheet peeled off therefrom.
