Third, a wide range of printable media. Flexo printing machines can print all kinds of paper, and can also print aluminum foil, plastic film, self-adhesive paper, self-adhesive film, glass paper, metal platinum and textiles. The type of printable media is more than gravure printing. In addition to the offset printing method, the rest of the media cannot be printed or printed badly.
Fourth, a wide range of product applications. Almost all paper and plastic packaging products can be printed by flexo printing. The printing effect on plastic film can be comparable to that of gravure printing. Due to the softness of the printing plate and the small printing pressure, it is especially suitable for corrugated paper and so on. In addition to packaging products, it is also possible to print books, newspapers, books, magazines, and other publications. At the drupa exhibition in 2000, we exhibited special flexographic printing presses for books and magazines.
Fifth, equipment comprehensive processing ability. Almost all narrow-width unit type flexographic printing presses can perform post-printing processing on the same device, such as reverse printing, coating, laminating, die cutting, cross cutting, slitting, punching, punching, fan folding, Automatic waste disposal, etc., can even add a number, bronzing or screen printing unit on the printing unit. Therefore, it is not unreasonable to call a flexographic printing press a print processing line.
6. Low production costs and high economic benefits. Compared with gravure printing, the platemaking cycle is short and the plate making cost is 30% lower; the ink consumption is 30% less than the gravure; the power consumption is 40%; the printing speed is fast and the unit type narrow web printing machine has a maximum printing speed of 150 per minute. In feet, the maximum printing speed of the satellite wide flexo press is up to 250 meters per minute; the reject rate is lower than the gravure and offset printing methods; it occupies less production space; and the integrated processing ability is strong, one forming, saving the labor of the subsequent procedures; The waste of turnover between processes is avoided; thus the overall production cost is low.
VII. Small investment in production. Because of the relatively simple structure of the flexographic printing press, the equipment investment is lower than that of offset presses or gravure presses of the same scale, generally saving 30% to 40%. In addition, in the case of narrow-width flexo presses, since it has almost all of its post-press processing functions, users have purchased flexographic printing presses, eliminating the need for additional post-press processing equipment such as die-cutting and polishing. This saves some of this investment. At the same time, it also saves space and labor for this part of the equipment. As a result, you can save a single investment in production.
Comparing flexo printing with gravure printing, all products that can be printed by gravure printing can be printed flexographically and can be at or near the quality level of gravure printing. However, flexible materials that can be printed with flexographic printing machines Can not be replaced by gravure; In addition, in terms of equipment investment and use costs, flexo printing is much lower than gravure printing. Undoubtedly, the use of flexo printing and packaging printing production is a wise choice for low investment and high output.
Although flexographic printing can achieve high precision, it suffers from the reason of embossing and anilox roller transfer, and its high-precision screen image quality still cannot be compared with offset printing. In the field of high-grade pictures and books and periodicals, offset printing is unquestionably superior to flexo printing, but in the field of packaging and printing, flexographic printing has the advantage of offset printing. First of all, ink consistency is the most basic requirement for packaging printing. Offset printing ink ink balance and ink emulsification problems, ink consistency has become a major challenge for offset printing, and this is the strengths of flexographic printing; Second, packaging design has A large number of color blocks, icons, offset printing in addition to ghosting issues, the ink layer is not thick enough, encountered a large area of ​​spot color has to be printed twice or even three times, but the flexographic printing ink layer thickness is far Exceeds offset printing. Furthermore, if there are few positive-opening packaging products, the use of offset or quadruple-platform offset presses will have more or less waste edges for each print, and flexographic printing will be used for cutting and cutting. The exact amount is reserved in millimeters, saving a lot of paper. In addition, the use of offset printing of packaging products, printing after the need for polishing, die-cutting and other post-press processing, the need for equipment and labor, and the use of printing, post-press processing integrated flexography machine, you can complete all at once In the process, the paper roll on one end of the machine and the product on the other end not only saves equipment investment, but also reduces the consumption caused by the turnover between processes and shortens the production cycle. Its efficiency is incomparable with offset printing. In addition, the flexographic printing plate's printing rate can usually reach 1 million to 3 million times, and the offset printing plate can only be printed with only a few tens of thousands of impressions after being processed. Therefore, although the flexographic printing plate making cost is higher, However, the printing plate is also resistant to printing. For long-lived jobs, the average plate making cost of a single product is also flat. Finally, except for paper, other printing media cannot be offset, even if the paper has a limited thickness range. In the flexo printing machine, plastic films and metal films can be printed, and the thickness of paper printing is also relatively large. (To be continued)
