Flexographic printing machine: Flexographic printing machine and offset printing machine are better

In recent years, flexographic printing has made great progress in China with its unique advantages in the field of packaging printing. Flexographic printing has been accepted by more and more people in the packaging printing industry in China.

Flexographic printing, known as aniline printing, originated in the United States in the early 1920s. Because of the toxicity of aniline dye ink, it has not been developed. Since the mid-1970s, due to the progress of the material industry, especially the advent of polymer resin plates and metal ceramic anilox rolls, the development of flexographic printing has made a qualitative leap and become a printing method with rapid growth worldwide. Especially in the United States, it has been fully developed. Both the manufacturing technology of printing presses and the application technology of flexographic printing represent the high level of flexographic printing. Most of the commodity packages seen in the domestic market of the United States are almost flexographic printing products. According to statistics, at present in the United States, the market share of flexographic printing in the field of flexible packaging printing accounts for 70%; 85% in label printing; 98% in the field of corrugated box printing; 25% in carton printing. In Europe, flexographic printing also accounted for 60%, 35%, 85% and 3% of the market share in the above packaging fields. In the United States, even 20% of newspapers are printed in flexo. This is enough to prove the vitality of flexographic printing,

Flexographic printing has its own advantages - fast, green and environment-friendly, as well as relatively fast matching processes. In Europe and America, flexographic printing has occupied the majority of the whole printing field. It is understood that some customers in Europe, the United States and Japan require that China's exported products use environment-friendly printing methods. In the United States, flexographic printing has been widely used in various printing fields, especially in the field of packaging printing, where flexographic printing accounts for a large proportion. Satellite flexographic printing will be the mainstream in the future printing field.

The difference between flexographic printing and other printing methods lies in its unique characteristics. First, the use of soft polymer resin plates, compared with gravure printing, not only reduces the cost of plate making, but also shortens the period of plate making. Due to the improvement of plate manufacturing level and plate making technology, the screen wire plate can now reach the line/inch level, which is enough to meet the needs of general packaging printing; The second is to use the anilox roll, which is both the ink transfer roll and the ink metering roll, to achieve the same short ink path as the gravure printing, and can accurately supply ink according to the process requirements. At present, the metal ceramic anilox roll with laser engraving can reach the line/inch level, in order to accurately control the ink color and ink

Thickness provides a favorable means; The third is zero pressure printing, which not only reduces the vibration and wear of machinery and the wear of plates, but also expands the range of printing media, especially for the printing of flexible materials; Fourth, the narrow width flexographic printing machine also expands the functions of the printing machine. In addition to printing, it can complete a large number of post press processes, making the flexographic printing machine a production line integrating printing and post press processing.
