The imitation metal etching printing process is a new type of printing process detection system and instrument developed on the traditional printing technology. The imitation metal etching printing process is to print a layer of uneven half on the smooth surface of the substrate such as gold and silver cardboard The transparent ink is then cured by a special ultraviolet light (UV) light source to produce an artistic effect similar to the etching or frosting of the metal surface.
The reason why the imitation metal etching printing process can produce special visual effects is to achieve a strong contrast between the mirror surface of the printed object under the illumination of the light source and the diffuse reflection displayed by the transparent or semi-transparent etched rough surface. The imitation metal etching printing process can be printed by using imitation metal etching inks such as UV wrinkles, UV ice flowers, UV crystals, UV refraction, etc., so that the printed surface has rich printing levels, beautiful patterns, fast drying of the printed surface, and strong wear resistance of the ink film Features. At the same time, the use of this printing process can also make the surface of the printed products soft, solemn, elegant, luxurious, three-dimensional, and present a printing art effect that is difficult to achieve with ordinary printing processes. The imitation metal etching printing process can be applied to high-end packaging products, such as tobacco and alcohol packaging, cosmetics, pharmaceuticals, health care products and other packaging boxes, Adobe can also be used for various commodity labels and various book covers, etc., to improve The artistic effect of the product itself and the packaging and decoration.
Today is an era of ever-changing scientific and technological levels. New materials, new processes and new technologies are constantly emerging, and new products are continuously created through interdisciplinary and cross-disciplinary science. Card products are another type of new products developed in the traditional printing industry.
Personalized printing
Introduce the matters needing attention in the application and production of imitation metal etching printing process on card products.
Card products are plastic cards that can store and record information. The production materials can be divided into polyvinyl chloride (PVC) and polyester (PET). The surface of the card is printed with inkjet printing of information such as patterns and related text descriptions. At the same time, a magnetic stripe can be attached to the surface of the card, and IC chips can also be embedded inside the card. Card printing methods include offset printing, screen printing or digital printing. The printing inks used in card products usually include metal inks such as gold and silver, or printing inks such as pearlescent materials. However, since the gold and silver printing inks are made of metal materials, their oxidation resistance is poor. For a long time, the gold and silver colors are easily oxidized and discolored, and the original metallic luster is lost. In order to avoid the above-mentioned disadvantages of plate-making and improve the metal gloss of the card surface, plastic materials (PVC or PET, etc.) with metal coating made by vacuum coating have been used. The plastic film base is provided with a vacuum coating layer, so that the surface of the plastic film base is coated with a layer of metal coating, and its metallic feeling is very strong and realistic, which makes the card surface shiny and colorful. The biggest characteristic of this material is that it is not easy to be oxidized and discolored, so that the printed surface of the card is bright and vivid. The structure / organization is rich, the layer is rich, and the three-dimensional sense is strong. Printing on the surface of the plastic material coated with vacuum coating must be printed with UV light curing printing ink. At the same time, in order to achieve the artistic effect of metal imitation etching printing, metal imitation etching ink must also be used for printing.
Metal-like etching inks are generally colored etching inks made by mixing various materials such as photosensitive resin into light-colored transparent or translucent pastes or adding colorants. For the production process of cards, first of all, we should start from the imitation metal etched layout design and plate making of the card surface. The imitation metal etched layout design must be cleverly conceived, designed and printed from the direction of the imitation metal etching refractive pattern, the angle and density of reflected light and refracted light Packaging city, at the same time, we must also fully consider the impact of the card surface after the high temperature and high pressure lamination on the card surface refraction or reflection pattern, and make full use of art design and metal imitation etching printing technology to make the card surface appear metal etching and bronzing Crafting effect.
UV printing
Plate-making operation control:
At present, metal imitation etching printing processes are all made by screen printing process. The mesh screen and the thickness of the photosensitive film are closely related to the fineness of metal imitation etching ink, because the metal imitation etching ink has a certain thickness, If you choose a manuscript with a too high mesh number, the ink will not pass easily due to the small mesh, which will cause uneven ink on the printed surface of the card, which affects the effect of metal-like etching on the card surface. Too much ink penetration makes the image on the card surface unclear. CTP in China will also affect the printing effect on the card surface.
Production process of imitation metal etching card products:
Art design of imitation metal etching pattern, plate making (offset printing plate, screen printing), printing (offset printing, screen printing), drying (UV curing, infrared drying), synthesis (film, magnetic stripe or embedded IC chip), stamping Cut), coding, hot stamping (or hot holographic logo), finished product inspection, packaging, storage.
Control over printing operations:
The imitation metal etching ink should be fully stirred before the card products are printed before it can be used to prevent the uneven distribution of the ink surface on the card due to the uneven distribution of the internal material of the ink or the phenomenon of poor ink removal during printing. At the same time, the characteristics of the silk screen imitation metal etching ink should be fully considered, and the printing pressure, scraping angle, screen height, etc. should be adjusted accordingly. In order to effectively control the leveling speed of the imitation metal etching ink on the card surface after printing, the viscosity of the ink should be carefully controlled when etching the ink ingredients, and the ink should be adjusted accordingly at any time during the printing process according to the actual situation. Printing to promote the formation of metal-like etching rough surface. In addition, in the printing process, the running speed of the light curing machine and the power and temperature of the ultraviolet lamp must be well controlled to avoid deformation of the printed card surface due to overheating during the process of passing through the light curing machine. Standards and certifications
It should also be noted that the biggest feature of card product processing is the use of multiple plastic film bases under high temperature and a certain intensity of pressure to laminate them into a whole card, and then die-cutting is finally made. Become a finished card. Therefore, the lamination temperature and pressure of the card should be properly controlled and adjusted during the production of the card. Otherwise, the artistic effect of the imitation metal etching printing process on the card surface will be directly affected by improper processing.
Card products processed by the imitation metal etching printing process have a strong contrast on the gold surface of the card surface, and the metal luster is very realistic. The printed image on the card surface has bright colors, full ink layer, bright layers, obvious metal etching effect, and has a strong Three-dimensional sense and visual impact. It can make the printed surface of the card appear high-end and luxurious, and truly reflect the unique artistic effect of the imitation metal etching card. By combining the imitation metal etching printing process with modern card manufacturing technology, a new exotic flower has been developed for the card manufacturing field .
