[0059] The ink preparation and printing were the same as those in Example 2. The printing speed is 3000 sheets / hour (about 70M / min). Printed on silver cardboard, the ink is slightly sticky after printing, and can produce patterns such as hemp sand and refraction, but except for the coral effect, the other patterns are not as good as Example 2. As in 200g / M 2 The light green bottom layer is first printed on the white cardboard, and then the coral pattern is printed with the gravure method with this ink. It is very elegant and can be used for packaging such as tea. It starts to harden after being kept at 80°C for 1 day. According t...

Abstract

The present invention relates to a decorative printing ink for gravure printing, its composition is formed from (wt%) 10-50% of oligomer, 10-40% of active diluent, 3-8% of photoinitiator, 0-46% of forming agent whose fineness is less than 10 micrometer, 0.01-1% of retarder and 0-5% of adjuvant. Said UV gravure printing decorative ink possesses reduced oxyinhibition and its solidifying speed is greatly raised, for example, UV light source is 80W / CMX3, at 150M / min. it can be well solidified, and can make cross-hatch with different effects, can print various patterns of imitation metal etching (corning), dioptric, buckle, ice flower and coral form, and its storage stability is good. Said ivnented product is a colorless one, the pigment or colour ink can be added, and the colour pattern can be printed.

Description

technical field [0001] The invention relates to an ink, in particular to an ink used for gravure printing, which can produce various decorative patterns such as imitation metal etching (hemp sand), refraction, wrinkles, ice flowers, corals, etc., as well as strong three-dimensional effects. Patterned UV-cured gravure decorative ink. Background technique [0002] At present, decorative printing such as imitation metal etching adopts screen printing method. I have made a detailed description in the article "UV Screen Printing Decorative Ink" in "Screen Printing" 2000, 6, P26-28. They have been widely used in the packaging of tobacco, wine, cosmetics, health care products, etc. There are many kinds of UV screen printing decorative inks with single performance, some are troublesome to use, and the production capacity is low. For example, the imitation metal etching ink can only be used to print patterns with a sand surface effect, and the ink has many varieties of coarse, medi...
