Problems solved by technology

The printing speed of letterpress printing cannot be too fast, if it is too fast, the printed graphics and texts will not be clear, and due to the thick imprint of letterpress printing, it is easy to appear sticky dirt, spots, patterns, poor gloss of printed products, poor color stacking, etc. The problem
The graphic part of the letterpress is easy to be damaged by collision. Once the page is damaged, it must be re-engraved, and the cost is high.

Embodiment 1

[0020] An identification code gravure printing process, including the following steps:

[0021] A: For the plate making of the printing plate, select seamless steel pipe as the printing plate base material, and laser engrave the information of the identification code on the printing plate base material;

[0022] B: Printing of identification code information, using a monochrome gravure printing machine to print the identification code information on a plastic film made of PET, the ink uses carbon ink, and the film thickness is 5 microns to form Ink information layer; when printing, the ink needs to be rolled on the printing plate substrate first, then the ink will naturally fall into the information printed part of the recessed identification code, and then wipe the ink adhered to the surface (of course the information of the recessed identification code The printing ink will not be wiped off), then put on the plastic film made of PET and use greater pressure to emboss the informa...

Embodiment 2

[0024] A: For plate making of the printing plate, a copper tube is selected as the printing plate base material, and the information of the identification code is electrically engraved on the printing plate base material;

[0025] B: Printing of identification code information, using a multi-color gravure printing machine to print the identification code information on a plastic film made of BOPP, the ink uses carbon ink, and the film thickness is 20 microns, forming Ink information layer; when printing, the ink needs to be rolled on the printing plate substrate first, then the ink will naturally fall into the information printed part of the recessed identification code, and then wipe the ink adhered to the surface (of course the information of the recessed identification code The printing ink will not be wiped off), and then put on the plastic film made of BOPP and use greater pressure to emboss the information printing ink of the recessed identification code on the plastic film ...

Embodiment 3

[0027] A: For plate making of the printing plate, a copper tube is selected as the printing plate base material, and the information of the identification code is electrically engraved on the printing plate base material;

[0028] B: Printing of identification code information, using a monochrome gravure printing machine to print the identification code information on a plastic film made of PVC, the ink uses carbon ink, and the film thickness is 10 microns to form Ink information layer; when printing, the ink needs to be rolled on the printing plate substrate first, then the ink will naturally fall into the information printed part of the recessed identification code, and then wipe the ink adhered to the surface (of course the information of the recessed identification code The printing ink will not be wiped off), and then put on the plastic film made of PVC and use greater pressure to emboss the information printing ink of the recessed identification code on the plastic film made...

Abstract

The invention relates to the technical filed of identification code printing, in particular to a gravure printing technology for identification codes. The gravure printing technology comprises the following steps: A. a seamless steel pipe or copper pipe is selected as a printing substrate for plate making of printing, and information of the identification codes is engraved on the printing substrate by electric engraving or laser engraving; B. printing of the identification code information adopts a single color gravure printer or a multicolor gravure printer to print the identification code information on a film substrate to form an ink information layer. An identification code content printed adopting the gravure printing technology has the advantages of strong ink color, rich colors, clear picture and text, proper contrast and lifelike image, in addition, the printing efficiency is high, the printing speed can achieve 100 m / min, and the cost is low.

Description

Technical field: [0001] The invention relates to the technical field of identification code printing, in particular to an identification code gravure printing process. Background technique: [0002] At present, the printing of identification codes mainly uses letterpress printing technology. The principle of letterpress printing is: the ink supply device of the printing press first distributes the ink evenly, and then transfers the ink to the printing plate through the ink roller. It is much higher than the non-graphic part on the printing plate. Therefore, the ink on the ink roller can only be transferred to the graphic part of the printing plate, and the non-graphic part has no ink. The paper feeding mechanism of the printing press conveys the paper to the printing parts of the printing press. Under the joint action of the printing plate device and the imprinting device, the ink in the graphic part of the printing plate is transferred to the substrate to complete the printing o...
