Tagging method of online variable information

Abstract

The invention relates to a tagging method of gravure online variable information. The tagging method is characterized in that a nozzle is additionally arranged on any traditional printing machine including a gravure printing machine, an offset press, a letterpress printing machine and a rotary flexo press, so that an online variable information printing system is formed. A marking image or a packaging image is still printed in any mode including the gravure printing machine, the offset press, the letterpress printing machine and the rotary flexo press, and the variable information of an explicit two-dimensional code or an invisible two-dimensional code is realized in a code spraying mode. The marking image or the packaging image and the variable information of the explicit two-dimensional code or the invisible two-dimensional code are performed on line on the same printing line. When the transformed printing machine is used for printing variable information markers or packages, the marking image or the packaging image is printed, and additionally, the variable information of the explicit two-dimensional code or the invisible two-dimensional code can be loaded; and the tagging method has the characteristics of low introduction cost, high printing efficiency and high printing precision of the marking image or the packaging image and is suitable for wide popularization, and one tag with one code can be realized.

Description

[0001] 【Technical field】 [0002] The invention belongs to an online variable information coding method in the field of image processing. [0003] 【Background technique】 [0004] In recent years, due to the popularization of variable information printing, variable information printing can be realized in mass production packaging, which improves product sales and improves customer service quality. In beverage water products, in order to promote the products, a product POP label is hung on the bottleneck of the beverage water product to inform customers of the promotional activities. At the same time, the link address of the homepage on the Internet is recorded, and consumers can get it by connecting the address on the mobile device. Detailed event information. Here, through the variable information printing technology, the lottery code is printed on the POP label of the product, and consumers who purchase the product can participate in the lottery and get luxurious gifts, which...
