Embodiment 1

[0048] Mix and fully wet 72.04 parts of cooked tung oil, 5.50 parts of pigment, 7.62 parts of silicon dioxide and 9.90 parts of wax, grind to a certain fineness through a three-roll ink mill, and then mix 4.95 parts of desiccant into it to obtain a gravure Ink products.

[0049] The basic parameters of the product are as follows: Viscosity: 4.5Pa.s / 40°C; ink fluidity: 21mm / 25°C; ink average acid value: less than 1mgKOH / g; drying time: 4 minutes / 80°C oven.

[0050] Printing conditions: ink printing viscosity: 1.5Pa.s / 40°C; pattern depth: 80-100 microns; printing speed: 6500 sheets / hour; printing pressure: 30 silk; gap between rollers after pressing: 2.1mm; paper: 90 grams of offset paper; drying temperature (paper surface temperature): 70-75 ° C.

[0051] Printing effect: The imprint (ink) of the obtained printed matter is protruding from the surface of the paper, and it has obvious unevenness when touched by hand; the ink color of the printed matter is distinct and has a stro...

Embodiment 2

[0053] 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 The concave-convex effect of the paper is obvious, and it has obvious unevenness when touched by hand; the ink color of the printed product is distinct and has a strong three-dimensional effect; the ink film is about 120 microns higher than the surface of the paper.

Embodiment 3

[0055] 16.05 parts of WY-1381 oil (the product of Beijing Wanlong Anti-counterfeiting Technology Co., Ltd.), 4.82 parts of WY-1380 oil (the product of Beijing Wanlong Anti-counterfeiting Technology Co., Ltd.), 6.42 parts of pigment, and 20.87 parts of #6 varnish , 8.51 parts of silicon dioxide, 7.22 parts of wax, mixed and fully wetted, ground to a certain fineness by a three-roller ink machine, and then 12.84 parts of liquid desiccant, composite desiccant (Beijing Wanyang Anti-counterfeiting Technology Co., Ltd. product) 16.05 parts and 7.22 parts of waxy tack remover are mixed thereinto to obtain a gravure ink product.

[0056] The basic parameters of the product are as follows: Viscosity: 20Pa.s / 40℃, ink printing viscosity: 2.15Pa.s / 40℃; ink fluidity: 25mm / 25℃; ink average acid value: less than 3.5mgKOH / g; Drying time: 7 minutes / 80°C oven.

[0057] Printing conditions: refer to Example 1. Printing effect: close to Example 1.

Abstract

This invention relates to a photograghic intaglio printing ink which equals to carving intaglio printing ink. It can be used in photographic intaglio printer, and its outstanding feature is that the price of the printer is cheap, lithographic cost is low, and the post-treatment step of sewage during printing process is unneeded, so the sewage from carving intaglio printing ink printing process iseradicated completely and with no environmental pollution, and the printing ink is no waste and its non-offset performance is very good. It dries quickly, so it shortens the production cycle and savesthe production buildings and land. The color of ink of its printing is of distinct hierachical structure and strong stereoscopic feeling. Its printing effect is the same as that of carving intaglio printings. The physicochemical fastness of its printing is superior to that of carving intaglio printings. Its printing cost is low.

Description

technical field [0001] The invention relates to the field of printing inks, in particular gravure inks. The invention also relates to the use of said 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. This technology is widely used in printing bank currency, securities, various certificates, tobacco packaging, pharmaceutical packaging, trademarks of famous and high-quality products, etc. Although this technology is a general technology, the present invention is recognized as a first-line anti-counterfeiting technology and...
