Abstract

The invention provides an engraving gravure printing ink and its preparation method and security products. The engraving gravure printing ink comprises the following components in weight percent: 40-70% of a binder composition, 10-25% of a colorant, and 5% of a composite filler -20%, wax 5-15%, composite surfactant 1-8%, ink modifier 0.5-5%, desiccant 0.5-3%, composite solvent 1-6%, the invention also provides the engraving Process for the preparation of gravure inks and security articles. The ink is a kind of engraving gravure ink through the selection and matching of the binder system, colorant, composite filler, composite surfactant, composite solvent and related auxiliary materials. This ink can effectively enhance the color expressiveness of printed products and improve printing The visual effect and aesthetic sense of the appearance of the product.

Description

technical field [0001] The invention relates to an engraving gravure printing ink, a preparation method and a security product, belonging to the technical field of printing. Background technique [0002] Engraving gravure printing technology is used for the printing of high-end products due to its unique pattern structure and outstanding gravure touch, especially for the printing of security products with anti-counterfeiting functions such as banknotes and special tickets. In recent years, in order to improve the unique public anti-counterfeiting technology of security products, while ensuring the feel of engraved gravure ink prints, the color saturation of engraved gravure ink prints has also attracted more and more attention. The existing engraving gravure ink, due to the selection of the used binder, the color value of the auxiliary agent, the poor transparency of the filler or the poor color saturation of the colorant, will affect the color and color saturation of the in...
