Abstract
The invention discloses a hot-pressing printing method. The hot-pressing printing method includes the following steps that an embossed embossing nickel plate is manufactured; ink is printed; gloss oil is printed; holographic patterns are printed in a hot-pressing mode. A piece of printed matter with the holographic patterns is obtained through the method and comprises a paper layer, an ink layer and a gloss oil layer, wherein the gloss oil layer is provided with the holographic patterns. The laser holographic patterns are directly positioned and printed on the gloss oil layer on the surface of the printed matter in a hot-pressing mode through a flat pressing printer, the transfer technology is not adopted, and thus raw materials such as PET films and glue are saved, and the environment is protected; the used gloss oil is used originally for the printed matter, and thus extra cost is not added. Meanwhile, the technical problem that positioning is not accurate in the prior art is solved through an original positioning system of the printer, and the expression effect of the holographic patterns is substantially improved.

Further, the temperature of hot pressing is 60-80 ℃.Hot pressing temperature is unsuitable too high, is preferably 60-80 ℃, because excess Temperature can destroy ink layer.
Further, the pressure of hot pressing is 5kg/cm
2.
Obtain a kind of printed matter with hologram pattern by above-mentioned hot pressing printing process, comprise paper layer, ink layer and gloss oil layer, on gloss oil layer with hologram pattern.
Further, hologram pattern direct heat is pressed and is printed on gloss oil layer.
Further, hologram pattern is relief type hologram pattern.
Further, gloss oil layer thickness is 8-10 μ m.By controlling coating speed, gloss oil layer is controlled to 8-10 μ m, can effectively improves the diffraction efficiency of hologram pattern, i.e. brightness.
Further, the thickness proportion of paper layer, ink layer, gloss oil layer is 20-30:2:1.
Further, the thickness proportion of paper layer, ink layer, gloss oil layer is 25:2:1.
Further, the gloss oil of formation gloss oil layer is water soluble acrylic acid general character resin.
Further, gloss oil is water soluble acrylic acid general character solution.
Again further, gloss oil is selected from 8300 types of Shanghai Wei Gela printing apparatus Co., Ltd, the G-155 type of sincere high-tech adhesive Co., Ltd of Shandong China or the DS201 type of Wuhan Di Sai high-tech research Development Co., Ltd.
Selected platen machine, holographic electroforming platemaking equipment, the flexible printing press of the present invention is the art common equipment, and this is not particularly limited.
Beneficial effect:
The method of printed matter hot pressing hologram pattern of the present invention is, by platen machine, direct laser holographic pattern positioning heat is pressed in to printed matter surface gloss oil layer.For printed matter laser hologram technique for applying of the prior art, direct heat compression technology of the present invention, does not adopt shifting process; saved PET film, the raw material such as glue, have protected environment; the gloss oil that uses for printed matter originally uses, do not increase extra cost.Utilize the original navigation system of printing machine simultaneously, solved prior art and located inaccurate technical problem, the embodiment effect of its hologram pattern significantly improves.
