Abstract

The invention provides UV offset printing and flexible printing combined UV light color ink, and a preparation method and application thereof. The UV light color ink comprises the following componentsin percentage by mass: 15 to 25 percent of polyester acrylate oligomer, 10 to 20 percent of acrylic ester oligomer, 20 to 40 percent of monomers, 2 to 3 percent of a dispersing agent, 3 to 5 percentof a photoinitiator, 5 to 10 percent of an organic pigment and 0 to 20 percent of a titanium dioxide powder. Solvent-free UV resin is adopted, the organic pigment and the titanium dioxide powder are added, an organic solvent does not exist in the whole process, VOCs are close to zero emission, the environment can be protected effectively, and the performance requirement and the integrated effect after printing are met by blending different UV resin.

Description

technical field [0001] The invention relates to ink technology, in particular to UV offset printing combined flexo printing UV light-colored ink and its preparation method and application, belonging to the technical field of printing applications. Background technique [0002] Cigarette pack printing ink has experienced the following development process: screen printing, solvent gravure printing, UV offset printing. [0003] Among them, the speed of screen printing is too slow, the efficiency is low, and the production capacity cannot keep up; the efficiency of gravure printing is high, but due to the strict control of VOCs emissions in today's environmental protection, solvent gravure printing will shrink in the future; UV offset printing is efficient and environmentally friendly, which is the main printing method. However, due to the fluctuation of the water-oil balance in the UV offset printing process, there will be obvious color difference in large-area solid printing. ...
