Problems solved by technology

Since the base paper for cigarette tipping paper is thin, has large pores, and absorbs quickly, if the existing water-based ink gravure printing technology is used, the printed cigarette tipping paper is prone to paper shrinkage and deformation, poor storage stability, and printed surface. White spots, insufficient hiding power, flocculation of pigment particles and other problems, resulting in waste of cigarette tipping paper
It is extremely difficult to formulate various performance indicators suitable for water-based inks printed with a plate cylinder groove depth of 38-42um

Embodiment 1

[0012] The first embodiment includes the production of printing plate cylinder, water-based ink preparation, printing coating, pre-drying, and oven drying.

[0013] First, the production of the printing plate cylinder. Make plate cylinders with a groove depth of 43-60um according to the requirements of cigarette tipping paper;

[0014] Second, water-based ink modulation. Due to the deeper groove depth of the printing plate cylinder, there are certain requirements for the technical parameters of the solid content and PH value of the water-based ink. At the same time, for the convenience of ink preparation, the water-based ink uses water-based acrylic resin ink with a solid content of 36%-55%. Then the pH value of the water-based ink is modulated with a pH value regulator, and the pH value is modulated between 9-10. The interaction of various technical parameters is described as follows:

[0015] a. The solid content of water-based ink is increased: due to the increase of the...

Embodiment 2

[0025] The second embodiment includes the production of printing plate cylinder, water-based ink preparation, printing coating, pre-drying, and oven drying.

[0026] First, the production of the printing plate cylinder. Make plate cylinders with a groove depth of 15um-37um according to the requirements of cigarette tipping paper;

[0027] Second, water-based ink modulation. Due to the shallow groove depth of the printing plate cylinder, the amount of ink in the printing plate cylinder is reduced. The viscosity of the water-based ink and the technical parameters of the pigment dispersion fineness must be considered when preparing the water-based ink. At the same time, for the convenience of ink preparation, the pigment dispersion fineness of the water-based ink is ≤ 15um water-based acrylic resin ink, and then use a thickener to adjust the viscosity of the water-based ink. Under the conditions of 4# Zahn cup and a temperature of 25°C, the viscosity of the water-based ink is ad...

Abstract

The present invention relates to printing technology, and is especially making process of cigarette paper printed with water-thinned ink. The present invention features the printing plate cylinder with slots of 43-60 micron or 15-37 micron depth, the water-thinned ink with solid content of 36-55 wt%, pH 9-10, pigment granularity not greater than 15 micron and viscosity of 18-50 s, and paper for cigarette treated through brush printing, pre-stoving and stoving. Compared with available technology, the present invention has the advantages of high production safety, clear printed pattern, convenient ink compounding, etc.

Description

technical field [0001] The invention relates to printing technology, in particular to a method for preparing cigarette tipping paper belonging to water-based ink printing. Background technique [0002] Cigarette tipping paper is a special paper (commonly known as tipping paper) that connects cigarettes and filters. When a smoker smokes, the cigarette tipping paper will directly contact the lips. Mandatory sanitary indicators and standards for paper loading to regulate the tobacco industry. As people's calls for smoking and health continue to rise, consumers have higher and higher requirements for the hygiene index safety of cigarette tipping paper. At present, all tobacco companies at home and abroad use tipping paper for cigarettes. They are all printed with organic solvent-based ink. After printing, a small amount of solvent remains in the tipping paper for cigarettes, which makes the content of arsenic and lead heavy metals on the high side, which is not good for the hea...
