Material-saving cigarette trade mark printing method

Abstract

A cigarette brand printing method which saves the materials includes three working procedures o printing, stamping holography and die-cutting. The three working procedures are: (1) printing from rollto roll, namely slot-free printing is carried out; besides, a registration mark is printed on paper; (2) stamping holography is carried out on roll paper circle by circle; automatic hot stamping, a stamping holography device which is provided with a locating registration device, is carried out; (3) die-cutting is carried out circle by circle by a roll paper die-cutting machine which is provided with the registration device and an under-pressure convex-concave device. As mark lines are arranged along the length directions of each screen period, the invention is provided with multiple sets of registration correcting devices and the length of each screen period is only 0.5 to 1 m, the calibration on the devices is much easier. The cigarette brand printing method has the advantages of saving energy and pressing convex during die-cutting, thus effectively avoiding roll-to-roll gravure, namely the attenuation problem of the pressing convex effect during on-line pressing convex; stamping holography circuit by circle stops the phenomena of fogging and frothing during the original printing process.

Description

technical field [0001] The invention relates to a printing process method and equipment, namely a material-saving method for printing cigarette trademarks. Background technique [0002] At present, the printing and production processes of cigarette trademarks that require hot holograms, that is, small cigarette packs, mainly include: ① printing, there are sheet-fed printing and web printing and then cutting into sheets; Single-fed paper flattening and round pressing are two ways. Flat pressing is: the hot stamping plate and the bottom plate are flat, and the surfaces are in contact when they are pressed together; circular pressing is: the arc-shaped hot stamping plate is fixed on the cylindrical honeycomb plate On the top, the bottom plate is flat, and it is line and surface contact when it is pressed together. ③Die-cutting is a flat die-cutting of a single sheet of paper, a total of three processes. [0003] Regardless of the ironing method of flat pressing or round pressi...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the disadvantages of waste of raw materials in the printing process of high-end products, the present invention proposes a new printing method for cigarette trademarks, which implements roll-to-roll printing, round-press round hot holography, round-press round die-cutting, and eliminates imposition The plate seam in the hot stamping process, that is, the waste of the bite and trailing tip, at the same time, the positioning and registration function is added to the circular press holographic and die-cutting equipment, thereby reducing the loss of paper and aluminum, and improving the input-output rate of raw materials
