Problems solved by technology

[0005] Now there are many good anti-counterfeiting technologies, all of which involve variable printing, and the packaging of public goods such as tobacco and wine can only be printed by offset printing machines such as Heidelberg due to the huge printing volume.
Moreover, when a new printing task needs to be completed, such traditional offset printing machines often need to make a new offset plate and use it to replace the offset plate in use to perform the printing task; obviously, this will affect the printing work efficiency and prolong the idle time of the printing unit
This limits the application of some anti-counterfeiting technologies combined with variable printing in this field

Embodiment Construction

[0048] In the following detailed description of the preferred embodiment, reference is made to the accompanying drawings which form a part hereof. The accompanying drawings show, by way of example, specific embodiments in which the invention can be practiced. The illustrated embodiments are not intended to be exhaustive of all embodiments in accordance with the invention. It is to be understood that other embodiments may be utilized and structural or logical changes may be made without departing from the scope of the present invention. Accordingly, the following detailed description is not limiting, and the scope of the invention is defined by the appended claims.

[0049] Those skilled in the art can understand that offset printing uses the principle that oil and water are immiscible, and uses materials with different molecular structures to make the graphic and blank parts of the printing plate, so that the graphic and text parts are ink-friendly and water-resistant, and th...

Abstract

The invention discloses a printing method, comprising the following steps: A. providing a network offset printing plate, the network offset printing plate contains a number of dot structures; B. printing a characteristic image on the network offset printing plate, the characteristic image Formed by part or all of the network dot structure; C. Transferring the characteristic image to the substrate through the mesh offset printing plate; repeating the steps A to C to realize variable printing of the substrate. The invention can realize the variable printing of the characteristic image, which is very beneficial to the anti-counterfeiting of the substrate and reduces the printing cost.

Description

[0001] This application claims the national priority of the Chinese patent application with application number (CN201410048272.9). The entire content of the Chinese patent application CN201410048272.9 is incorporated herein by reference. technical field [0002] The invention relates to the field of printing technology, in particular to a printing method and a printing device capable of realizing variable characteristic images based on traditional offset printing. Background technique [0003] Traditional offset printing is currently the most economical batch printing method. Since this printing requires plate making, one plate corresponds to one graphic, it can only realize batch printing of fixed graphics. To achieve variable printing, such as variable text, graphics, etc., is currently achieved through digital printing or inkjet printing. [0004] Generally speaking, for a printing of a certain format, the cost of traditional offset printing is basically the same as that...
