Abstract

The invention discloses a holographic positioning accurate printing method. The method comprises the steps that a hot stamping film with graphic and text information is manufactured; coating of imaging coating is carried out to form the hot stamping film with an imaging layer; an optical positioning mark is set, and in combination with computerized automatic typesetting, holographic patterns are printed on a printed material in a hot stamping manner through cold stamping printing; and the hot stamping film is separated from the printed material, coating of a UV coating is carried out, and gravure printing is carried out after curing. According to the holographic positioning accurate printing method, the method of setting the optical positioning mark on the hot stamping film and achieving positioning in combination with computerized automatic typesetting is adopted, so that the precision and the accuracy of a holographic positioning hot stamping technology are effectively improved. According to the holographic positioning accurate printing method, a laser rainbow hologram is applied to manufacturing the hot stamping film, meanwhile, the innovative imaging coating is combined, so that the imaging layer of the hot stamping film has high definition and stability, and it is guaranteed that the optical positioning mark can keep the position stability for a long time. The printed material is coated with the UV coating, and scratch resistance of the surface of printed matter can be effectively improved after curing.

Description

technical field [0001] The invention relates to the technical field of packaging printing, in particular, to a holographic positioning precise printing method. Background technique [0002] Laser holographic anti-counterfeiting technology uses holographic technology, that is, according to the principle of laser interference, laser holograms are made by using the method of spatial frequency coding. The so-called holographic technology is an advanced photographic technology that records all the information in the reflected light waves of the object being photographed. "Holography" refers to all information about the light waves emitted by an object, including both amplitude or intensity and phase. The expressive ability of hologram text is incomparable to that of ordinary text. It can not only reproduce the main image of the original object, but also show different side shapes of the original object as the direction of the observation line changes. In recent years, due to th...
