First, the basic principles and basic knowledge of flexo printing.
The basic principle and flexographic printing as offset printing also belong to indirect printing. as the picture shows:
A: Rubber Roller B: Anilox Roller C: Plate Roller D: Pressure Roller E: Resin Plate F: Cell Net on Anilox Roller G: Ink H: Substrate
The ink is wiped by the rotation of the rubber roller, and the ink is stored in the F and held in the hole by its tension. When contacted with the E on the C roller, the ink is transferred to the resin plate with graphic (ie, protruding dots). The part is then rotated and pressed by the C roller and the D roller onto the substrate H to complete a single-color printing.
The core parts are B and E. In fact, B is the anilox roller: it is called the heart of a flexo printer. The depth and depth of the mesh (ink storage capacity) and shape directly affect the quality of printed products.
E is direct contact with the substrate, and its quality is certainly understandable. The photosensitive resin plate that is used now is invented by Miss Chen of the Chinese company DuPont; now the maximum resolution can reach 175 lines, and some more beautiful printing can be completed.
B flexo printing has received more and more attention from the world today due to its environmental friendliness. Regardless of whether they use water-based or alcohol-based inks, it is really environmentally friendly to the current printing inks such as offset printing. In recent years, flexo printing in the world has greatly exceeded the speed of other printing.
Flexo printing was first used in carton packaging. Today, carton packaging is still the largest user of the flexo printing market. It will not be known if it will change in the future. In addition: shopping bags, handbags printing; envelopes, letterheads, notebook page printing; paper cups, paper food bags; napkins; trademark printing and other aspects are used. Everyone often eats McDonald's, KFC and other cups, food paper products are flexo, and the country's McDonald's paper products are printed in Guangzhou's development zone.
China's flexographic equipment and water-based inks are still at a relatively low level. After joining the WTO, its market potential will be immeasurable, and Utah is playing an increasingly important role in China's global economic integration. Of course, the matching anilox roller must also be a great article to do.
Second, the development of anilox roller and its classification of ceramic anilox roller in the development of flexographic history flexo India first originated in the United States in 1938, the roller on the pattern is pressed into the up, production is very rough, mainly used in the carton On the outer packaging (also known as industrial packaging), the use of iron roller. However, during use, it was found that the wear of the roller was very large, which made it difficult to ensure the printing quality and the printing cost.
In 1939, the anilox roll was electroplated and its outer surface was plated with a harder metal such as chromium, but it was still difficult to meet the requirements.
In 1970 it was proposed to use hard ceramics to make anilox rollers. However, it is extremely difficult to grind the ceramic. Until 1984 by the maturity of the development of laser technology and the extensive application of various industries. Laser anilox rollers were formally adopted. In 1989, this technology was introduced by Taiwan's Yiming Company.
Laser engraved ceramic anilox roller An early anilox roller engraving format, using surface chrome plating, mechanical engraving, applied to slightly thick carton or plastic printing processing and coating. When the chrome-plated anilox roller is used at the beginning, the printing effect is not bad, but because the metal surface is relatively easy to wear, the service life of the anilox roller is very short. In addition to the limitations of the shape of the mechanically engraved mold, the number of lines cannot be increased, and it is even difficult to meet the needs of mid-range flexographic printing. It is believed that as the time passes, the ceramic roll will gradually be replaced.
