Description

technical field

[0001] The application belongs to the technical field of digital inkjet, and in particular relates to a UV inkjet ink and a preparation method thereof. Background technique

[0002] In recent years, the digital inkjet industry has developed rapidly. UV inkjet is a digital inkjet technology that uses ultraviolet light to cure. It has the advantages of simple operation, wide range of applicable media, no need for post-processing, energy saving and environmental protection. UV inkjet is developed on the basis of UV-curable printing inks. The working principle is the same as that of UV-curable printing inks, and the composition of the ink affects the properties of the cured film.

[0003] Corrugated paper is a commonly used packaging material. It has the advantages of low cost, light weight, easy processing, high strength, excellent printing adaptability, and convenient storage and transportation. Most of the corrugated paper can be recycled, which is relatively ...
