Method for producing non-laminating anti-curling label capable of being labeled automatically

Abstract

The invention relates to a method for producing a non-laminating anti-curling label capable of being labeled automatically, and belongs to the technical field of printing. According to presswork, a printing machine is online for glazing in a surface finishing process to replace an original laminating process, printing is achieved through material preparation, CTP platemaking, plate discharging and multi-machine combination, especially an all-in-one machine composed of a six-color or seven-color printing machine online glazing unit printing machine and a collection drying unit is adopted for achieving one-shot paper feeding to complete production, meanwhile, the amount of sprayed powder is reduced, transparency of the presswork is improve and drying time is shortened. Various physical indexes of the presswork reach or exceed usability of an original laminated label and environment friendliness and low consumption are achieved.

Description

[0001] This application is a divisional application with an application date of June 26, 2012, an application number of 201210214298.7, and an invention title of "A Production Method for Lamination-Free, Anti-Curl Automatic Labeling Labels". technical field [0002] The invention relates to a production method of a film-free anti-curl automatic labeling label, which belongs to the technical field of printing and dyeing. Background technique [0003] The wide application of labels and the continuous development of label varieties have naturally promoted the development of label printing technology. How to improve production efficiency, improve product quality and reduce environmental pollution has become the development direction of label printing technology. [0004] In order to protect the label from moisture, water, dirt, wear, folding, and chemical corrosion, the commonly used label printing technology in the prior art is to use an off-line lamination process. There are ...

AI Technical Summary

Problems solved by technology

[0007] Disadvantages of a large amount of powder coating process: ①Reduce the brightness and scratch resistance of printed matter

②When laminating, if the printed matter is sprayed with too much powder, it cannot be completely dissolved by the glue, and a large area of ​​snowflake failure may occur

③Contaminate the surface of the machine and the blanket, causing environmental impact on the production workshop

[0008] 2. The use of off-line laminating machine lamination technology increases the production process, resulting in the extension of the production cycle, and at the same time increases the uncontrollable quality risk

[0009] In the traditional process, each process is carried out separately, and materials need to be transferred in the middle, which increases the input of manpower and material resources, and prolongs the production cycle. Deformation, contamination, abrasion and other problems

[0010] 3. The use of lamination is not environmentally friendly, and it is easy to cause the label to curl in reverse

[0011] The label coating material is generally a refractory polymer film, which has high recycling costs and is not an environmentally friendly choice

[0012] At the same time, in the label structure, due to the difference in technical indicators such as the surface tension and moisture absorption of the two materials of paper and film, the label curls and warps

In addition, the coated paper is too thin, water content, loose paper, poor flatness, high pressure, high temperature, long time during lamination, low ambient temperature and high humidity will cause curling and deformation of the laminated label

Such problems have long affected the production efficiency of high-speed filling and labeling
