Embodiment Construction

[0017] In order to prevent the engraving gravure printing ink from drying out and ink aging during the printing process, the present invention adds an ink stabilizing agent composed of slow drying agent and non-volatile oil according to a certain proportion on the basis of common engraving gravure printing ink components, wherein The retarding agent is selected from butanone oxime or butyraldehyde oxime. Most of the binder systems used in the existing engraving gravure printing inks are phenolic resins and alkyd resins, and methyl ethyl ketone oxime or butyraldehyde oxime are particularly suitable for the application of binders in which phenolic resins are dispersed in tung oil. The non-volatile oil is selected from soybean oil. Soybean oil is a semi-dry vegetable oil with light color and is not easy to turn yellow. It is often used to produce alkyd resin. Adding it to engraving gravure printing ink has little effect on ink color, but also has a great influence on dryness Smal...

Abstract

The invention relates to printing ink for an engraving plate, which is capable of prolonging the ageing speed, belongs to the technical field of printing and is used for solving the problems of easy dry plate, ageing and so on of the ink. The compositions of the ink comprise binder, a surfactant, synthetic wax, filler, pigment, a solvent and a drying agent. After the ink compositions are subjected to modification, an ink stabilizing auxiliary agent is added into the ink compositions, and the addition of the ink stabilizing auxiliary agent is between 0.5 and 3 percent of the total weight of the ink compositions; and the ink stabilizing auxiliary agent comprises the following substances in percentage by weight: 10 to 50 percent of drying-inhibiting agent and 50 to 90 percent of nonvolatile oil. The printing ink for the engraving plate has good printing suitability and stability; the ageing speed of the ink is reduced; no dry-plate phenomenon of the ink is generated during the printing process; the drying time required by the technology can be met after printing, and the printing technological cycle is not influenced; no organic solvent is required to be sprayed during the printing process; and the printing ink for the engraving plate has the characteristic of environmental protection, and printed matters have no problems of reverse smearing, smearing and so on.

Description

technical field [0001] The invention relates to a printing material, especially an ink used for engraving gravure printing, and belongs to the technical field of printing. Background technique [0002] Engraving gravure printing technology is widely used in the printing of printed matter such as bank currency, securities, various certificates, tobacco packaging, pharmaceutical packaging, trademarks or packaging decoration. The existing engraving gravure printing inks will have different degrees of aging and dry plate phenomenon during the high-speed printing process, and the aging phenomenon of engraving gravure printing inks characterized by low ink consumption is particularly obvious, resulting in ink piles and light flowers on printed products, affecting Print quality. In order to solve the above problems, at present, the organic solvent is directly sprayed on the ink fountain roller during printing. Although this method can solve the ink aging problem to a certain exten...
