       In the post press processing of printed matter, the surface finishing effect of printed matter is loved by people. The surface finishing processing of printed matter mainly includes polishing or film coating to improve the gloss of printed matter; Die cutting and indentation, concave convex embossing or crystal three-dimensional drop plastic processing to improve the three-dimensional sense of printing; New And Diversified Bronzing Technology To Improve Printing Quality

       Refraction, bronzing and so on to enhance the flicker of printed matter. The combination of bronzing and embossing not only has the characteristics of gloss, three-dimensional feeling and flicker, but also has high anti-counterfeiting performance.New And Diversified Bronzing Technology To Improve Printing Quality

      Bronzing is to use the template installed on the hot stamping machine with the help of a certain pressure and temperature. The process of pressing the printed matter and the hot stamping foil in a short time, and transferring the metal foil or pigment foil to the surface of the hot stamping printed matter according to the picture and text of the hot stamping template.New And Diversified Bronzing Technology To Improve Printing Quality

       Bronzing process is widely used in high-grade and exquisite packaging and decoration, trademarks, book covers and other printed materials, as well as household appliances, building decoration, craft cultural products and so on.New And Diversified Bronzing Technology To Improve Printing Quality

       It is also widely used in high-end packaging such as greeting cards, invitations, banknotes, cigarette labels, drugs and cosmetics.New And Diversified Bronzing Technology To Improve Printing Quality

      Hot foil not only has a good decorative effect, but also has a strong anti-counterfeiting function. It can prevent counterfeiting by copiers and scanners. It has become an important material for governments all over the world in the anti-counterfeiting of large banknotes, ID cards and passports. New And Diversified Bronzing Technology To Improve Printing Quality

     The color of the bronzing foil can be changed in a variety of ways when watching. Among the 10 Dutch guilders, the color of the bronzing foil used changes from silver white to blue, and then to black; Europe adopts holographic gold foil for anti-counterfeiting.New And Diversified Bronzing Technology To Improve Printing Quality

Various bronzing techniques

       In terms of bronzing processing technology, it can be divided into two forms: first ironing and then printing and then ironing. Most bronzing is first ironing and then printing. For example, ordinary gold, laser gold hot stamping and holographic hot stamping are widely used in hot stamping on gold cards, silver cards, laser cards and glass cards, and have been widely used in western countries.New And Diversified Bronzing Technology To Improve Printing Quality

      Holographic positioning bronzing adopts corresponding anti-counterfeiting patterns, with special process, safety and anti-counterfeiting function, which has been recognized all over the world. The holographic positioning probe is used to accurately control the anodized aluminum with high bronzing quality.

       As the manufacture of holographic electrochemical aluminum is difficult in China, there are few manufacturers: the process is complex, so it is difficult to copy and the cost is high.New And Diversified Bronzing Technology To Improve Printing Quality

        It is usually favored in the anti-counterfeiting of high-end cigarette boxes, large cheques, retail gift certificates, ID cards and coins. New And Diversified Bronzing Technology To Improve Printing Quality

      For example, it is used on the front page of passports, and the anti-counterfeiting is carried out through the complex pattern with official confirmation on it as the identification mark.New And Diversified Bronzing Technology To Improve Printing Quality

       Most bronzing is direct bronzing on printed matter, as well as bronzing on the surface of UV varnish and on self-adhesive film materials. The process of bronzing on the surface of UV varnish has very high requirements for UV varnish and anodized aluminum for bronzing. During bronzing, it is necessary to ensure that they adhere closely and have good bronzing suitability. New And Diversified Bronzing Technology To Improve Printing Quality

      Bronzing on the self-adhesive film material is divided into direct bronzing on the film and bronzing on the surface of the ink layer. This process should prevent the ink layer or gold foil from falling off and false bronzing. New And Diversified Bronzing Technology To Improve Printing Quality

       Therefore, the film surface should be pretreated to ensure the bronzing quality.New And Diversified Bronzing Technology To Improve Printing Quality

       Ironing before printing is a new idea in the printing industry and cigarette label design. Hot stamping before printing is to hot stamp silver foil on white cardboard first, and then print pictures and texts on the surface of hot stamping silver foil.New And Diversified Bronzing Technology To Improve Printing Quality

       It is a large-area hot stamping technology. This processing method usually adopts circular flattening or circular embossing and bronzing machine.New And Diversified Bronzing Technology To Improve Printing Quality

       During hot stamping, the pressure is in line contact mode. During large-area hot stamping, unlike flat flattening and hot stamping, bubbles will appear. The hot stamping surface is very flat, and full plate hot stamping will not increase the load of the machine.New And Diversified Bronzing Technology To Improve Printing Quality

New bronzing Technology

1. Three dimensional bronzing Technology

       Three dimensional bronzing is a process that uses corrosion or engraving technology to make bronzing and concave convex graphics and texts into a female mold and male mold matched up and down, so as to realize the one-time completion of bronzing and pressing concave convex.New And Diversified Bronzing Technology To Improve Printing Quality

       This process completes the concave convex pressing of the hot gold mouth at the same time, reducing the waste products produced by the processing process and overprint. The production efficiency and product quality are improved.

        Three dimensional bronzing often uses bronzing embossing materials with high resolution. When viewing pictures and texts from different angles, they can show different colors, realizing the ideal function of anti duplication and anti-counterfeiting.New And Diversified Bronzing Technology To Improve Printing Quality

       The fine levels of pictures and texts are covered to avoid tampering and forgery of tickets and documents. Pearl pigment can also be used in transparent foil materials, which will show different colors when viewed from different angles.New And Diversified Bronzing Technology To Improve Printing Quality

        Three dimensional bronzing can adopt flat, round and round bronzing die-cutting machines. Bronzing uses etched copper plate or engraved brass plate. New And Diversified Bronzing Technology To Improve Printing Quality

      Corrosion red copper plate is used for plane bronzing, with short service life, generally 100000 times; New And Diversified Bronzing Technology To Improve Printing Quality

      The service life of engraved brass plate can reach 1 million times, which is suitable for long plate live and good bronzing quality. The concave convex bottom mold is prefabricated with gypsum or glass fiber materials,New And Diversified Bronzing Technology To Improve Printing Quality
