Abstract

The invention relates to the technical field of ink and in particular relates to black ink capable of preventing oxidizing discoloration after gilding as well as a preparation method and application method thereof. The black ink capable of preventing oxidizing discoloration after gilding is prepared by uniformly mixing yellow ink, red ink, blue ink and reflex blue. When the black ink capable of preventing oxidizing discoloration after gilding is applied to printing, the concentration requirement and the blackness effect requirement can be met by carrying out overlapped printing several times. The black ink capable of preventing oxidizing discoloration after gilding is prepared by mixing the yellow ink, the red ink, the blue ink and reflex blue, and thus, meets the requirement that carbon black is not contained, has the effect of furthest solving the problem in the prior art that oxidizing discoloration is caused by contact between the black ink containing carbon black and gilding materials, and has the advantage of good gilding effects.

Description

technical field

[0001] The invention relates to the technical field of inks, in particular to a black ink for preventing oxidation and discoloration of bronzing, a preparation method and an application method thereof. Background technique

[0002] In order to improve the texture of the printed matter, various surface treatments or bronzing processes are generally performed on the surface of the printed matter. Under normal circumstances, yellow, red, and blue inks can be directly stamped after printing. However, if there is black in the printed graphic color, there will often be a problem of oxidative discoloration after stamping. If you encounter direct hot stamping on black monochrome dots or solid graphic parts, the problem of oxidative discoloration will be more serious. Because offset printing black inks generally use carbon black as the coloring material, but due to the structure or composition of carbon black and bronzing materials are prone to oxidation, so bronzing...
