Printing method for labeling label at low-lying part of deeply recessed container

Abstract

The invention relates to a printing method for labeling labels at low-lying parts of deeply recessed containers. The printing method is characterized in that in order to prevent a two-dimensional codeon a packaging container from being read through stealing before a consumer purchases a product, improve code identification sensitivity and prevent the product in the container from being contaminated by printing ink, the printing method for labeling the labels at the low-lying parts of the deeply recessed containers is implemented by the steps of: printing an optically readable computer graph code on the back surface of a transparent thin film in a spraying mode, and arranging a non-setting adhesive layer larger than the code layer on the code layer; directly connecting the periphery of thenon-setting adhesive with the transparent thin film in a sealed manner, and at least adhering one protective layer on the non-setting adhesive; and finally performing die cutting to form a labeling label. The printing method can realize high-speed mass tagging at bottle caps or low-lying parts of deeply recessed containers which are generally impossible to be tagged, and can prevent the food andbeverage from being contaminated by the printing ink.

Description

【Technical field】 [0001] The invention belongs to the field of image processing and relates to a printing method for marking labels on low-lying parts of concave deep containers. 【Background technique】 [0002] With the concrete application of the concept of the Internet of Things, people finally see clearly that it is a de-conceptual practicability with less investment and quick results between popular mobile phone reading, connecting products to the Internet to realize product promotion, public anti-counterfeiting identification of products, and big data analysis of products. technology. [0003] Therefore, no matter what the product is, it has become a trend to realize public mobile phone identification through variable information coding. However, how to code products with high efficiency and low cost has become a subject of attention. [0004] For this reason, there have been many publications on patents related to this aspect in the past year. In China, the German cod...

Problems solved by technology

[0017] The first purpose of the present invention is to solve the problems of low coding efficiency of lasers, large restrictions on coding materials, and low coding quality that is not easy to identify, especially for bottle caps that have been produced, especially for brand companies. A product that cannot be changed, providing a method to solve all the problems caused by the current laser coding through the direct coding process without changing the existing bottle cap material and structure

[0019] The third purpose of the present invention is: to provide a method of spraying protective film to solve the problem that jet printing ink cannot contact beverage or food
