激光雕刻网纹辊在柔印中的作用(国外英文资料) The role of laser engraving anilox roll in flexo printing.Txt The role of laser engraving anilox roll in flexo printing Murata 12-17 laser roller (Shanghai) Co., Ltd. The emergence of ceramic anilox roll, flexo printing quality, stability has made great progress. The accuracy of gravure printing is about 16 times that of letterpress printing, and the dot density is 80 ~ 1800L/in. In general, flexible printing in the number of lines generally less than 150L/in, more than 175 L/in, not only to increase the difficulty of flexo printing plate, but also to shorten the service life of the printing plate. The screen line number from the number of printing, and printing quality of top line gravure and offset printing flexographic printing are high, but if we consider the flexographic printing of no pollution, saving resources and high printing efficiency and low operating cost advantages, in ceramic roller manufacturers position, through the improvement of printing machine, plate making technology ink, and operation technology, flexo printing is a great space for development of. Print line number is the improvement of high quality printing performance, chrome plated roller before the carving line number and net hole depth, the volume is fixed, with the print screen line number increase, carving lines should also be increased accordingly. As a result, the volume of the mesh holes is reduced and the ink carrying capacity is reduced, which can not meet the requirements of the printing concentration, and can only be used in the low grade printing field. The ceramic laser engraving roller not only has excellent wear resistance of the ceramic roller, but also uses the continuous improvement of laser processing technology, can be prepared with ideal ink volume of high wire number roller. This is because the roller inking size get by changing the anilox line number; on the other hand, for the same line number of roller, can also change the net hole depth or
