Flexographic printing is the use of flexo, transfer printing ink by the anilox roll. Its printing principle is: Use strong liquidity-fluid ink, the ink from the ink fountain roller and the rubber anilox roll spread of the graphic part of the plate and allowed to dwell, then printing pressure exerted by the impression cylinder, the printing the ink is then transferred on to the substrate, and finally dried and complete the printing process. Flexo and other printing methods as required plates, ink, ink transfer device, substrates, printing equipment, but the flexographic printing has greater advantages and better technology, and in the anilox its own use , plates, ink and coating aspect, with a similar gravure anilox short inking, to precisely control the amount of transfer ink; printing through the use of non-film, thin plates, CTP laser engraving technology to improve outlets finesse, full of color gradation and reproduction; ink falls plates and substrates to achieve less ink film transfer density and good performance, namely low ink quantity, high color. In addition, it can also be combined printing Changping label printing, that is based flexo printing and finishing mixing other units, usually contain a combination of print flexo, screen printing, offset printing, letterpress, flat press and so on; printing, polishing, cutting, stamping, gluing bag completed in a production line. While these latest technologies flexo, but the resulting large-cho seen its development potential, the breadth and depth of development. Another major advantage of flexo printing range is wide, printable flexible plastic film, sprayed aluminum, self-adhesive labels and packaging paper, paper bags, card boxes. But in the flexographic process, equipment, ink, anilox, substrate material and printing plates and other factors must be properly used in combination in order to obtain high-quality printing products. Ink printing process is the material used to form the graphic information, which can be seen in the printing ink is about to play a decisive play, it will directly affect the printed image tone, color and sharpness. In print, we need to understand the composition of the ink and ink classification. Their wide range of physical properties vary, and some very thick, very sticky; while others are quite rare. Some vegetable oil as binders; some with a resin and a solvent or water as binders. These are based on the object that is printed substrates, printing method, print media type and drying methods to decide. Printing ink pigment as the main solid components label printing, it will play an important role, the relative density of printing inks, transparency, heat resistance, light resistance and resistance to chemical corrosion, etc., are concerned with the pigment. The role of pigment in the ink is obvious, its color determines the printing ink hue; its size determines the amount of ink concentration; its use to certain physical properties of the ink and consistency; its use under certain extent impact printing ink drying Huang Jiang label printing, oxidative polymerization drying ink based printing was particularly prominent. Furthermore, in all aspects of printing ink durability it is determined by the pigments. Since the printing ink varieties for different purposes, the pigment is also equipped with some differences, which requires printing should be based on product use, selection process characteristics compatible inks, such as high-speed multi-color printing press packaging products should be used in light, fast solid ink abrasion resistance to ensure print quality.
