First, the development trend of flexographic printing at home and abroad flexographic printing previously known as aniline printing, due to toxic and harmful aniline ink, gradually eliminated. It is replaced by a water-based ink that is non-toxic, non-toxic, and environmentally friendly. In the past decade or so, due to the rapid development of the packaging and printing industry and the wide application of photosensitive resins, it was later called flexible printing.
In the past ten years, the flexographic printing in the United States and Western Europe has developed rapidly, and the proportion of offset printing and gravure printing among the people has gradually declined in several printing methods, while the proportion of flexographic printing has gradually increased. This change is particularly noticeable in packaging printing. China's flexo printing technology started late and developed slowly, which has restricted the development of China's packaging and printing industry. Therefore, the State Economic and Trade Commission has also formulated a series of corresponding preferential policies in printing to encourage the introduction, research and development of flexographic printing presses.
In recent years, China's domestic printing industry has had new understanding and requirements for flexographic processes and technologies. With the many domestic flexible printing development strategy seminars, exhibitions, technical exchanges and communications organizations to go abroad for inspection activities, etc. A comprehensive understanding and understanding of the application of the latest technology in flexo printing, as well as the high quality color printing products witnessed in domestic flexographic printing plants, it is believed that the quality of flexo printing products can be comparable to that of concave offset printing. Can fully meet the needs of high-end color packaging printing products.
Second, the advanced nature and reliability of flexographic printing technology In the United States and Western Europe, where the printing industry is developed, flexographic printing not only has great growth, but also has a broad space for development. After all, it represents the trend and mainstream of the printing industry today. This is due to the technical performance and characteristics of the flexographic printing itself. It is summarized as follows:
1. The equipment has good performance, simple structure, low cost, and low equipment investment.
2, a wide range of applications. Not only for packaging and printing, but also for newspapers, books and magazines. According to foreign materials, about 50% of printed matter in commercial prints can be printed on flexographic printing presses. The effect of printing on PVC film can be comparable with that of gravure printing. At the same time, due to its small flexible pressure, it is especially suitable for the printing of substrates, such as corrugated paper, which cannot withstand high pressure.
3, use a wide range of materials. Such as thin paper, thick paper, cardboard, plastic film, aluminum foil, sticker paper, metal foil and so on.
4, high economic efficiency. Flexographic plate printing costs only 10%-20% of gravure printing, consumes one third less ink than gravure printing, saves electricity by 40%, and rejects paper is only 1%-2%. The average scrap rate is higher than that of offset printing and Gravure printing is low, which reduces production costs. The entire industry in flexo printing says that the economic benefits are high.
5, The plate making cycle is short, the loading time is less, the printing speed is faster, and the entire production cycle is short. The unit type flexo press can print at a speed of up to 150 m/min. The speed of a satellite flexo press can reach up to 300 m/min. (Gravure is only about 90-130 meters per minute), especially after printing. , Bronzing, indentation, screen printing, marking, die-cutting and other post-press processing equipment connected to form a continuous post-press. Therefore, the production cycle is much shorter than other print processes. Therefore, flexo printing is more suitable for single-species and high-volume packaging and printing products.
6. The use of water-based inks that do not pollute the environment, in addition to being suitable for non-toxic, non-polluting green packaging, is also conducive to environmental protection.
Due to the superiority of flexographic printing, it has developed rapidly in recent years in developed countries in Europe and America. According to the latest information provided by the United States, there are currently more than 7,000 flexographic printing lines in the United States. One third of the printing industry is completed by flexo printing.
Third, the company introduced the introduction of the flexographic printing press content:
In order to speed up the adjustment of the company's product structure, the rapid realization of the integration of "anti-counterfeiting and color printing" is promoted. In June 2002, the company introduced an internationally advanced, domestic first-class Canadian Yajia hair green environmental protection flexo printing one.
Its performance and configuration are as follows:
1. Model: Canadian Agafa CLX 20.5 "(maximum print width of 520mm).
2, color group: 9 colors plus 1 set of UV rotary screen printing unit.
3, printing range: 70 grams - 400 grams of paper
4, printing speed: 150 meters / minute
5, This machine has a double-sided dust removal system, corona device, coating system.
6, ultrasonic automatic correction device.
7, tension automatic control system.
8, cardboard and roll paper reverse frame printing system.
9, in addition to static electricity system.
10, 6 sets of UV configuration, park pressure die cutting and indentation system.
11, sheet and roll paper receiving system.
12, UV ink and water-based ink system are also equipped.
13, hot air drying and infrared, ultraviolet three drying devices.
14, automatic paper cutting alarm system.
15. Quickly change the anilox roller and impression cylinder system.
In addition, in order to meet the printing requirements of the flexographic printing presses, the printing process also purchased Taiwan's automatic park flattening computer bronzing, die-cutting machine, automatic flat-pressure die-cutting machine, high-speed automatic four-fold paste box machine each one station.
The company's products are located in: various small packaging boxes and "security and packaging integration" products. Such as medicine boxes, cosmetics boxes, cigarette cases, food boxes, etc.
