Printing silver or gold on the material with metallic ink spot color; Hot stamping or hot stamping is to use high temperature to hot stamp anodized on the material. Printing silver or gold is matte; Hot silver or bronzing is the effect of strong light. Simply put, spot color is a kind of color specially used for printing, and gold and silver with spot color are often used in usual design. When designing, fill the place where spot color printing is needed into a color, and when making up, take out the spot color separately and send it to the film, and it can be printed with spot color ink. Fake gold and fake silver are similar to gold and silver in order to save costs. The gold one is C20Y60M20 and the silver one is K30. In printing, printing gold and silver belongs to the printing process, and bronzing silver belongs to the post-processing process. The color of printed gold and silver is far less bright than that of gilding and silver plating. In the effect of bronzing and silver plating, the place to be bronzed is raised separately, and the bronzing plate is specially bronzed, which has nothing to do with printing. Hot stamping With the rapid development of hot stamping foil and packaging industry, anodized hot stamping is more and more widely used. Such as: book cover bronzing, gift box bronzing, tobacco and alcohol, clothing trademarks and packaging boxes bronzing, greeting cards, invitations, pens bronzing, etc. , with a variety of colors and patterns, special edition can be customized according to specific requirements. The base materials of hot stamping are ordinary paper, printing paper with gold and silver ink, plastics (PE, PP, PVC, ABS and other engineering plastics, etc. ), leather, wood and other special materials. Galvanized aluminum hot stamping foil mainly uses heat and pressure to transfer patterns or characters to the surface of hot stamping materials. In order to complete this process, a bronzing machine and a bronzing template (such as zinc plate, copper plate, silicone plate, etc.) are needed. ) engraved with special words or patterns need to be heated to the required temperature, transfer the required pressure and maintain the corresponding elbow space. It should be noted that when hot stamping different materials, it is necessary to choose the appropriate model of anodized and the appropriate temperature, pressure and hot stamping time to achieve the ideal hot stamping effect. Main features, specific uses and precautions of anodized aluminum: Hot stamping features: clear pattern, beautiful appearance, bright color, wear resistance and weather resistance. In the printed cigarette labels, bronzing technology accounts for more than 85%. In graphic design, bronzing can make the finishing point and highlight the design theme, especially for trademarks and registered names. Product application: 1. Ordinary gold and laser gold bronzing. It can be used for hot stamping on most products, including gold cards, silver cards, laser cards and glass cards, which are widely used. 2. Positioning holographic bronzing. Holographic laser positioning anodized aluminum is a special technical application in design. With corresponding anti-counterfeiting patterns, the anti-counterfeiting ability and quality of products can be greatly improved. This kind of anodic alumina is generally produced in China. Compared with imported goods, the price is cheaper, but the bronzing performance is slightly worse. The location of anodized by holographic laser is closely related to the control of hot stamping temperature, hot stamping pressure, vehicle speed and even hot stamping model. 3. Special application of anodic alumina in the process. Printing after ironing is a new idea for cigarette label design and printing industry. The application of this process requires highly anodized aluminum. In addition to the requirements of accurate bronzing position, smooth and bright surface, even pressure, no foaming and no paste, special attention should be paid to the obvious indentation on the edge of bronzing pattern, and the bronzing anodized should have good adhesion on the hot stamping surface, and there should be no obvious scratches and scratches. As we all know, the bronzing process is actually a process in which paper is heated and pressed. For white cards and glass cards, special attention should be paid to the protection of semi-finished products, and various unfavorable factors of paper deformation should be reduced as much as possible in the production process, which is of great help to the smooth progress of stamping process and the improvement of product qualification rate. In the application of bronzing process, we will encounter the problem of how to improve work efficiency in production, especially the process improvement of mass products is very necessary. The surface of UV varnish is directly bronzed, which has high requirements for UV varnish and bronzing anodized aluminum. Pay attention to control the oil quantity when glazing, so as to ensure that the varnish coating of the whole batch of products is relatively stable, and the oil layer should be thin and flat. For anodized aluminum used for bronzing, it requires high temperature resistance, good adhesion and good adaptability to varnish bronzing (the resin type used in varnish matches the hot melt adhesive used in anodized aluminum bronzing). Among all products, this process has a small scope of application. In addition, the bronzing of anodized aluminum on gold, silver ink and matte oil also has high requirements for bronzing surface and bronzing anodized aluminum. If the ink particles on the bronzing surface are large or the surface is rough, it will directly affect the normal bronzing. Precautions 1. It is necessary to select the appropriate hot stamping foil according to the different types of objects to be ironed. When hot stamping, we must master the coordination of temperature, pressure and hot stamping speed, which is different according to the different hot stamping materials and hot stamping areas. 2. When cutting, we should master the speed and direction of turning tool. 3. The electrochemical aluminum foil for hot stamping should be made of paper, ink (especially black ink), kerosene, compound glue and other materials, and the hot stamping parts must be kept dry to avoid oxidation or damage to the bronzing layer. 4. The general packaging is: 64CM? One roll 120M, one box for each roll 10; Can be customized with width of 64CM and length of 120M or 360m or other special specifications. 5. When stored, it should be placed upright, pressure-proof, moisture-proof, heat-proof and sun-proof, and placed in a cool and ventilated place.
