Abstract

The invention provides a carving gravure ink and a preparation method and a safety product thereof. The carving gravure ink comprises the following components by the weight percentage: 40-70% of a connecting material composition, 10-25% of a colorant, 5-20% of a composite filler, 5-15% of wax, 1-8% of a composite surfactant, 0.5-5% of an ink regulator, 0.5-3% of a drying agent, and 1-6% of a composite solvent. The invention also provides the preparation method and the safety product of the carving gravure ink. The carving gravure ink is obtained through selection and matching of the connecting material system, the colorant, the composite filler, the composite surfactant, the composite solvent and the related accessories; and the ink can effectively enhance the printing product color expressive force and increase the printing product appearance visual effects and aesthetic sense.

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...
