Analysis on the application prospect of flexographic printing in folding carton (Part 2)

in fact, there are many successful examples of flexographic online printing of folding carton. For example, in Meitong, Australia, France and the UK, they use the online system to make beverage packaging, bath products packaging, chocolate packaging and cigarette boxes. The printing materials of these online systems are also very extensive, such as cardboard, paper, plastic and aluminum foil. Since drupa200 passed various ways 0, China has also introduced many sets of online systems and achieved great success. However, we are surprised that such a large packaging market is not suitable for our country. Moreover, these online systems have not been really popularized and applied in China, so all printers need to redouble their efforts

according to statistics, in drupa 2000, about 150 high-grade multi-color flexographic presses were put into use in the United States, and about 30-50 such flexographic presses were put into use in Britain, France, Denmark and other European countries. Most of these flexographic machines use on-line system, and most of them use UV ink. People can't help asking: where is the profit margin of flexographic machine online system? The prints with a large number of prints are printed by the on-line system of flexographic press, which has obvious advantages. Otherwise, the advantages of flexographic machine on-line system are difficult to show. Some people have made statistics: for prints with a printing capacity of less than 50000, offset printing will have a lot of profit space, while for flexographic online system with huge equipment, the profit will be very little or even no profit; The printing pieces with a printing number of 50000 ~ 1000 meters are still a small business for the flexographic machine on-line system, but the profit is still considerable; Flexographic printing machine online system will be an ideal choice for prints with a printing number of more than 100000 meters

in terms of the current packaging and printing market, the prices of packaging products are getting lower and lower, and the profit margin of packaging and printing is getting smaller and smaller. This is an opportunity for flexographic printing to use the pressure measuring film to convert the oil pressure into the change of strain gauge resistance. Because flexographic printing is especially suitable for occasions where the requirements of printing accuracy are not very high and the price requirements are relatively low. Here we should remind all packaging enterprises using flexographic printing that all prepress processes must be carefully checked before printing, and all production factors must match each other, such as flexographic printing plate, sleeve, roller, flexographic ink and printing materials used. Only in this way can we ensure the printing quality and effectively prevent the emergence of waste products

vitality brought by new technology

for the traditional offset printing folding carton printing process, the development of new technology is a useful supplement rather than a challenge. The use of flexographic machine on-line production line to print and produce folding cartons has brought unlimited business opportunities and markets to carton manufacturers. These new technologies include the direct plate making technology (CTP Technology), the application of a new generation of roller technology and sleeve technology, the use of new flexographic ink system and independent transmission technology, etc

direct plate making technology is a very important front-end technology for narrow width rotary flexographic press used in folding carton production. It can ensure that the plate making technology develops in a simpler and faster direction, shorten the whole plate making operation time, make the step range and fine level replication effect more competitive, and greatly improve the point quality of the printing plate. Due to the direct plate making technology, the printing plate quality is greatly improved. Because flexographic printing ink is generally fluid, the use of flexographic printing process will produce a thick and solid ink layer and polishing layer on the surface of the print

the printing format of narrow width rotary flexographic printing press is generally between 150-600mm. This flexographic plate machine can be assembled in the form of a single unit and mixed with other printing machines as needed. It can also be mixed and assembled with other post press processing devices, such as glazing, window pasting, film coating, bronzing and coding devices. In this way, people can combine the flexographic press with other equipment in the form of modules to form an online production line according to needs, so as to reduce the transportation and storage of semi-finished products between printing and post press processing, so as to reduce the production cost

the printing format of the medium web rotary flexographic press is generally between 600 ~ 800mm. This kind of printing machine is generally unit type, up to 10 units, and is equipped with a large drying device. Of course, the drying device can also be a UV drying device. The printing machine can realize double-sided printing, and can also be combined with other post press processing equipment to form an online production line

the printing format of the wide rotary flexographic press is generally between 800-l700mm. The printing press adopts satellite structure, which is very flexible. People can also improve it as needed to form an online system. The most ideal combination is to combine the wide rotary flexographic press with the circular rotary die-cutting machine to form an on-line system. The system is highly automated and mechanized, and the production capacity is amazing. The printing speed can reach 450m/min. However, the adoption of the online system needs enough long version, otherwise it will be difficult to give full play to its advantages
