① network changes and maintenance of the ink roller proofs, it will harden proofer with ink roller deteriorate. Hardening of the ink roller means roll with a long time, the surface will become light and hard until a layer of "crystal layer." When the roller surface crystallization severe, its performance will be affected ink transfer, ink proofing process will be difficult to maintain balance. Especially magenta ink, as water absorption decreased, the phenomenon will cause the network appear hollow. Such proofs internet point area will be smaller than the dot area on the film, the color will be lighter. That desaturation. In some instances, the bridgehead clothes tag tag printing, when the same color of the network has changed, it will cause a shift in color tone proofs of the desired effect, multi-color overprint color change will be greater. Thus the bridge tag printing custom, how important it is for the maintenance of the ink roller. In addition to have a fixed daily weekly cleaning procedures, but also specific maintenance measures. That is two weeks to take down roller proofer "rest" about the bridge tag printing, put the spare ink roller. So as to make the ink roller to maintain a good working condition, thereby obtaining a satisfactory quality dot reproduction. ② maintenance blanket blanket is transferred to the network from the plate to the media on paper. Its performance has a direct impact to the transmission network quality. Blanket with a long time that I will have chemical residues on the surface attached to the elastic blanket becomes small. It would be transferred to the network edge sharp enough on paper. Thus, after working for some time we should give it blanket down "rest" look, so as not to make fatigue. A printed version of the production classification 1) Category: The printed version of the production process of different printing processes bridgehead tag printing company, printing plates can be divided into: engraving and etching edition. Engraving is the use of electric carving machine, the V-shaped groove depth different angles with different needles, after blow on the copper roll forming, and then plated with copper roll surface wear layer of chromium, after polishing Shanghai Electric, on It can be used on gravure presses. In the printing process, relying on the V-shaped groove on top of the ink transferred to the paper. Corrosion version is the use of imaging technology, the image produced on the surface of a copper roll, then using etching method, the roll surface form a U-shaped groove CTP, and then plated branded and polished surface. 2) Compare: intaglio and corrosion performance version of the initial difference is not big, but big differences between the two of life. Engraving the surface of the V-groove, after the wear, the groove depth shallow, V-shaped with the bottom of the groove width is narrowed print inspection, the area of ??the dot becomes small, decreasing the amount of ink grooves, printing color quickly faded , resulting print edition scrapped. Engraving depth in the carving process if control is not good, too deep in the printing process is likely to cause ghosting and tail; shallow when the status quo and trends, the life of the printing plate has been significantly affected. Etching plate surface is formed U-shaped groove, with shallow depth of printing plate wear, recess, but did not change the network area, and reduce the amount of ink is relatively slow evaluation, for printing color is no big change, so its service life is longer. Bridgehead tag printing factory _ beyond printing (certified) _ tag printing bridge by the Dongguan Chang Ping beyond packaging products factory provided. Dongguan Chang-ping beyond packaging products plant (www.dgcyp.com) Dongguan, Guangdong, printing paper leaders, over the years, the company implement the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. In all walks of life beyond the printing leadership with the staff warmly welcomed the inquiry negotiations to create a better future beyond printing.
