To the first half of the twentieth century, after being adopted to print non-absorbent transparent cellophane packaging material, its application rapidly expanding flexo plate making, involving a variety of synthetic resins and polyethylene film, flexo printing method as packaging materials in Europe countries laid the foundation. Japan from the early twentieth century was the introduction of the technology used to print corrugated, paper, etc., the US and Europe is different, at first has not been applied to the field of flexible packaging material and liquid carton flexo, there are two reasons, one of the flexographic printing not satisfied with the quality, the second is already introducing gravure and offset printing technology to meet the demand. Recently, with the flexographic printing technology has caught up with the environment flexo gravure and offset printing material, so expansion has accelerated. State of the art nearly six years, advances in flexographic printing technology, indeed enviable. It's the reason why is that the appreciation of all aspects of the printing press ①, ② anilox, ③ plates, ④ plate, ⑤ inks have the innovation, (2). Anilox roll past on anilox core is chemical etching means, or is administered after the mechanical engraving surface hard chrome plating is made, its number of lines at most 400-500lpi, thus printing lines can only be limited 100-120lpi. Due to limited printing differentiate force, with not very stable in terms of quality and other factors, in Japan, it has not been promoted in flexible packaging, carton printing field. Later, after the development of the anilox ceramic core spray using a laser engraving, the maximum number of lines reached 1200lpi. Any degree of its ink-shaped hole also expanded. So the number of printed lines of energy reached 300lpi. Currently, the Japanese number of lines in the packaging gravure printing is 1200lpi, life rolls also leap improvements made for flexible packaging printing so totally not a problem.
