Embodiment 1

[0066] 70.54 parts of water-soluble maleic anhydride modified tung oil (product of Beijing Wanyao Wujitian Safety Ink Co., Ltd.), 7.52 parts of silicon dioxide, and 9.00 parts of wax were mixed and fully wetted, and ground to A certain fineness, then 8.95 parts of liquid film-forming aids and 3.99 parts of ethylene glycol monobutyl ether are mixed into it to obtain water-based gravure ink and / or water-soluble screen printing ink equivalent to the ink.

[0067] The basic parameters of the product are as follows: Viscosity: 2.5Pa.s / 40℃; average acid value of the ink is less than 3.5mgKOH / g; drying time: 3 minutes / 80℃ oven.

[0068] Printing conditions: ink printing viscosity: 1.5Pa.s / 40°C; pattern depth: 30-70 microns; printing speed: 6500 sheets / hour; paper: 90g offset paper; drying temperature (paper surface temperature): 70°C .

[0069] Printing effect: the imprint (ink) of the obtained printed matter has obvious unevenness when touched by hand; the ink color of the printed ...

Embodiment 2

[0071] On the basis of Example 1, add expansion agent 120D of 4% of the total amount of ink, adjust the drying temperature (paper surface temperature) to 120-125°C, and keep other printing conditions unchanged, the imprint (ink) of the printed matter obtained , Touching it by hand has obvious uneven feeling, and the ink film thickness can reach 80 microns.

Embodiment 3

[0073] 35.05 parts of WY-3100 water-soluble acrylic resin (product of Beijing Wanyao Wujitian Safety Ink Co., Ltd.), 13.91 parts of WY-3100A water-soluble acrylic resin (product of Beijing Wanyao Wujitian Safety Ink Co., Ltd.), polyethylene glycol 20012.84 parts of alcohol, 8.42 parts of pigment yellow, 8.51 parts of silicon dioxide, 16.27 parts of WY-616, mixed and fully wetted, and ground to a certain fineness through a three-roll ink padding machine. According to the viscosity of the ink, use 5.00 parts of Ethylene glycol monobutyl ether adjusts viscosity to obtain water-based gravure ink and / or water-soluble screen printing ink equivalent to this ink.

[0074] The basic parameters of this product are as follows: the viscosity is controlled at 1.0-4.5Pa.s / 40°C, the printing viscosity of the ink should be less than 1Pa.s / 40°C, and the printing viscosity should be ethanol and / or water and / or ethylene glycol monobutyl ether Adjustment; the average acid value of the ink is less...

Abstract

The invention is equivalent to water soluble intaglio ink of plate engraving ink and / or equivalent to water-soluble screen printing ink of the ink, suitable for a gravure printing machine. The ink has the advantages of nontoxicity, tastelessness, nonflammable property, water solubility, non-environmental pollution and rapid drying; the printing effect of the obtained presswork is the same as or equivalent to the printing effect of the plate engraving presswork; the materialized firmness of the presswork is superior to the materialized firmness of the plate engraving presswork; the ink is low in printing cost and suitable for printing secure and confidential documents with deep printing lines, such as bank notes, securities, stamps, food packing, etc.

Description

technical field [0001] The invention relates to the field of printing inks, in particular to water-based gravure inks. The present invention also relates to the application of the water-based gravure ink. Background technique [0002] Gravure inks are divided into engraving gravure inks and photographic gravure inks. [0003] Engraving gravure ink is specially designed for engraving gravure printing machine. The imprint (ink) of the printed matter obtained by engraving gravure printing technology is protruding from the surface of the paper, and it has obvious unevenness when touched by hand; the ink color of the printed matter The layers are distinct and the three-dimensional sense is strong. Engraving gravure ink is widely used in printing bank currency, securities, various certificates, tobacco packaging, pharmaceutical packaging, trademarks of famous and high-quality products, etc. Prior to the present invention, gravure printing technology was recognized as a security...
