Detailed Description
In order to better understand the purpose, structure and function of the present invention, the present invention relates to a micro-nano optical intaglio printing press and a printing method thereof, which are described in further detail below with reference to the accompanying drawings.
Each group of the prior intaglio press comprises a printing plate roller and an embossing roller, the printing plate roller is engraved with patterns to be printed, the image-text part of the printing plate is concave, and the blank part and the excircle of the printing plate cylinder are on the same plane. The impression roller is disposed vertically above the plate roller. When the intaglio printing press prints, the whole plate surface of the plate roller is inked, the ink in the blank part of the plate surface is scraped by a doctor blade, the ink in the image-text part is left, then paper is passed between the plate roller and an embossing roller, the embossing roller is used for embossing on the back surface of paper, the ink in the concave part is directly transferred to the paper surface, and finally the printed matter is piled or rewound by a paper collecting part. The number of colors printed at one time according to the unit operation is divided into single color, four colors, five colors, six colors and the like.
The improvement of the invention is that after each unit is used for printing each color of plane pattern, the printing of optical pattern is carried out, as shown in figure 1, one group of intaglio printing press is set as a feeding group 1, a first plate roller 11 of the feeding group 1 is a smooth surface roller, namely, the roller surface is smooth and has no concave-convex lines, and is used for polishing oil, a first embossing roller 12 is vertically arranged above the first plate roller 1, a feeding pool 13 is arranged below the first plate roller 11, a part of the roller of the first plate roller 11 is immersed in the feeding pool 13, and the polishing oil is coated on the whole paper after passing through the first plate roller 11 and the embossing roller 12.
The group after the feeding group 1 is set as an optical printing group 2, a second printing plate roller 21 on the optical printing group 2 is made of transparent materials such as organic glass, resin and the like, the surface of the second printing plate roller 21 is coated with a micro-nano optical plate, the sleeve position of the micro-nano optical plate is circumferentially and longitudinally adjusted by using an adjusting mechanism of a gravure printing machine until the sleeve position has zero deviation, and the thickness of the micro-nano optical plate is 100-200u. The micro-nano optical plate is plated with a metal layer by vacuum magnetic sputtering, and the metal layer can be chromium, nickel and other metals.
