Four-color Flexographic Printing Machine

Four-color flexographic printing machine is a common printing machine, can be used for all kinds of packaging materials printing, widely used in food packaging, pharmaceutical packaging, paper printing and other fields.This article will provide a detailed introduction to the working principle, characteristics, and application field of the printing machine produced by Huawei Machinery, hoping that readers will have a comprehensive understanding of the equipment.

The four-color flexographic printing machine adopts flexographic printing technology, and its core principle is to use the relief ink slot to contact the printing material, so that the graphic part on the letterpress transfers the ink to the surface of the printing material. This principle is consistent with the basic printing logic of letterpress printing machine and flexographic printing machine, and is also connected to the printing logic of specific products such as non-woven bag printing machine and joss paper printing machine. At the same time, it integrates the advantages of multi-color overlay printing technology of four-color printing machine.Compared with other printing methods, it has the following notable characteristics.

Firstly, it has high speed and efficiency. Because the relief printing machine adopts the continuous ink supply method, the printing speed is faster, and the high-speed printing speed of tens of meters or even hundreds of meters per minute can be achieved, which greatly improves the printing efficiency. This advantage is highly compatible with the demand for mass-produced non-woven bag printing machine and joss paper printing machine, and is not inferior to the efficient printing performance of four-color printing machine, while inheriting the high-speed operation characteristics of the printing machine.

Secondly, the machine printing quality is higher. The ink groove of the letterpress is in contact with the printed material, so that the printing ink is evenly transmitted to the surface of the material, and the printing pictures are clear and bright. At the same time, the letterpress press can also print according to the set pressure and speed, and can meet different printing requirements through simple adjustment, and the print quality is strong.

Thirdly, flexible relief printing machine has wide applicability. A wide variety of materials can be printed by letterpress presses, including paper, plastic film, flexible packaging materials, etc. Different types of the machine can also be configured with different printing frames to adapt to different thicknesses and widths of materials to meet various printing needs. In the field of food packaging and pharmaceutical packaging,the printing machines are widely used.

Compared with traditional printing methods, flexographic printing machines have some obvious advantages. First, the letterpress press has a layer of pressure gasket between the ink tank and the surface of the printing object, so that the ink amount of the ink tank is adjusted more accurately than the traditional printing method. Secondly, the automatic cleaning system of the relief printing press is more perfect, which can timely clean the ink tank and the ink scraper, reduce the downtime of the printing press and improve production efficiency.

Fourthly, the application field of flexible relief printing machine is very wide. In the field of food packaging, it can be used for printing all kinds of packaging bags, wrapping paper, packaging boxes, etc. In the field of pharmaceutical packaging, the machines are mainly used for the printing of pharmaceutical packaging boxes, drug instructions, etc. In the field of paper printing, it can be used for printing paper packaging boxes, paper bags, etc. In addition, the printing machines can also be used in electronic product packaging, daily necessities packaging, beverage packaging and many other fields.

The non-woven bag printing machine focuses on the pattern and text printing of non-woven bags, while the joss paper printing machine specifically serves the printing needs of joss paper. The four-color printing machine has its own place in the field of multi-color fine printing, and the letterpress printing machine and flexographic printing machine are the basic types of printing equipment. They work together with the four-color flexographic printing machine to meet the printing needs of different scenarios.
