Flexographic printing technology entered a new era

a century ago, flexographic printing was only a very insignificant and insignificant printing process. At that time, it was also called "aniline printing" because aniline ink was used at that time. With the application of new materials and the improvement of printing conditions, flexographic printing technology has risen rapidly. It completely abandoned aniline ink, replaced by solvent based ink and water-based ink, and the quality of printed matter has been significantly improved. Today's flexographic printing process is not what it used to be. It has developed into another major printing process after embossing, offset printing and gravure printing. In North America, flexographic printing currently accounts for about 22% of the total printing market. In the packaging industry, flexographic printing has become the leading printing process, accounting for two-thirds

it is predicted that flexographic printing will still maintain a good growth momentum. In the printing market of corrugated boxes, labels, flexible packaging, paper bags and folding cartons, flexographic printing is growing rapidly and its market share is rising. Most of its businesses are snatched from the traditional embossing, offset and gravure printing markets

with the improvement of the processing technology and precision of the corrugated roller, the quality level of the flexographic printing process is also constantly improving. Ten years ago, the number of lines of the wrinkle roll was generally limited to 360~440 lines/inch, but today it has reached 800 lines/inch, and may be higher. The higher the number of roller lines, the thinner the ink layer transferred. Therefore, it is necessary to use ink with higher hiding power. In addition, drying cannot occur on such fine roller. No. 7 Correct installation on a solid foundation will cause a paste

in addition, flexographic printing has also promoted the development of high-speed flexographic printing machine. However, this has some difficulties for the flexographic printing system using water-based ink, because the high-speed printing machine requires a high concentration of pigment in the ink and good transfer performance of the ink

ctp technology before consulting, we'd better learn more about manufacturers with similar quality for comparison. The development of CTP technology has brought great changes to the flexographic printing industry and greatly improved the quality of flexographic printing products. It has become a major development direction and trend of flexographic printing process to use laser technology to directly image and make on photosensitive polymer plates in order to help cosmetics manufacturers and cosmetics packaging suppliers in packaging inspection and quality control, and to cooperate with the use of closed doctor blade and ceramic roller, And it is mainly used in "two workers cooperate with each other to disassemble a car heart embossing (satellite) printing machine.

UV drying ink began in the mid-20th century, but it has not made great progress until the past two decades, and will continue to maintain an amazing growth rate. In the flexographic printing of trademarks and labels, almost a quarter of the business is printed with UV ink

uv ink has no pollution, and there is no volatilization of water and solvent at all. There is no volatilization of solvent in the printing process, so the printed matter has bright color, small dot expansion rate and good reducibility. The quality of printed matter can be comparable to offset printing products. Therefore, the application of UV technology makes flexographic printing have the strength to compete with offset printing

in wide flexographic printing, there are few successful examples of UV ink, mainly because the wide flexographic printing machine is mainly used in the food packaging industry, and people are very concerned about whether UV ink will pollute food

recently, benzene was found in cationic UV inks in Europe, which has further aroused people's attention to such problems. Moreover, some UV ink suppliers have abandoned the cationic UV ink business and no longer operate cationic UV ink. Cationic UV flexographic printing ink is very suitable for the printing of wide web materials that require very high UV radiation resistance, such as fertilizer bags

water-based inks are widely used

in flexo printing, water-based inks are the most widely used and have an absolute advantage. For example, water-based inks are used in the printing of corrugated boxes, paper bags, paper products, milk boxes, etc. However, in the printing compound of plastic film, although the growth rate of water-based ink is relatively slow, it still maintains a certain growth trend. In addition, in folding carton printing and some gravure printing businesses, water-based inks are expected to see new growth points

in recent years, the voice of environmental protection has been very high. Governments of various countries are also continuing to take measures to protect the environment on which human beings depend, and have successively formulated a series of laws and regulations to strengthen efforts to control and reduce the emission of organic volatile substances; Environmental protection organizations are also strictly restricting the emission of ozone, which will eventually affect the emission of VOC (organic volatile matter) into the atmosphere. Such measures have promoted the promotion and application of water-based ink

in the development history of the printing industry in recent years, the rise of flexographic printing technology is one of the most remarkable events. In the face of various challenges (such as production costs, government administrative regulations, etc.), we must adopt new technologies, find our own way out according to needs, and continue to improve and develop with the adoption of new technologies. Flexographic printing is a typical example. With the application of new materials and new technologies, the disadvantages of flexographic printing, such as slow drying and poor gloss, have been successfully solved. Today's flexographic printing is a world different from the past. Due to the advantages of high quality, high efficiency, low cost and no pollution, flexographic printing has a very broad application prospect
