Abstract

The invention discloses a water-based ink for cork paper bobbin intaglio printing, which is characterized by comprising the components in parts by weight as follows: 23 to 50 parts of watercraft acrylic resin, 10 to 40 parts of pigment, 5 to 25 parts of curling preventing auxiliary, and 0.05 to 2 parts of defoamer, wherein the curling preventing auxiliary is polyatomic alcohol or ester. The water-based ink for cork paper bobbin intaglio printing has the advantages of feasible matching process, high inking performance, stability in storage, high on-machine printing effect, high printability, high post-printing adaptability and high cigarette performance, and can completely meet the requirements on design and printing, and is completely suitable for intaglio printing at a high speed, and has an extremely good effect.

Description

technical field [0001] The invention relates to a water-based colored ink for tipping paper gravure printing and a preparation method thereof. Background technique [0002] Tipping paper is an imported name. It was first produced by a Japanese company. It got its name because its appearance is similar to the outer skin of a plant called tipping paper. At present, most of them are still called tipping paper in China, and some are also called tipping paper. Base paper weight is generally 35g / m 2 Left and right, the main purpose is to cover the filter tip on the top of the cigarette, firstly to protect the filter tip, secondly to avoid direct contact between the human mouth and the filter tip, and thirdly to increase the appearance. The earlier tipping papers were basically in the same style, the color was mainly soft light yellow, and the pattern was mainly to make people intuitively feel the cross-section of the shredded tobacco in the cigarette. The current tipping paper is...
