Abstract

The invention discloses a water-based color ink for tipping paper gravure printing, which is characterized in that it contains the following components in parts by weight: 23-50 parts by weight of water-based acrylic resin; 10-40 parts of pigment; 5-25 parts of anti-curling auxiliary agent; defoaming Agent 0.05~2; Wherein, described anti-curling auxiliary agent is polyhydric alcohol or ether. The water-based color ink for tipping paper gravure printing of the present invention has a feasible proportion and process, good ink-forming performance, and stable storage; the printing effect on the machine, printing suitability, post-press suitability, and cigarette performance are good, and it fully meets the design and printing requirements. Requirements, fully suitable for high-speed gravure printing, with extremely good results.

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...
