Current market situation of metal container printing

metal decoration, taking tinplate as an example, copies colors and patterns to the surface of tinplate through printing. By the end of the 20th century, three generations of technologies have been used in sheet metal printing. They are: the first generation, letterpress printing: printing and reproduction of patterns/words, lines and color blocks by letterpress assembly

the second generation, photographic printing: take the reproduction of photographic works as the symbol to realize the printing and reproduction of image hierarchy and gradation

the third generation, color printing: combine four-color color printing photography with electronic color separation technology to realize full-color image printing and reproduction

traditional metal printing includes offset lithography and roll printing, etc. as far as tinplate is concerned, offset lithography is mainly used. Because the tinplate substrate is not absorbent, the drying room curing treatment is used to volatilize the solvent in the ink. Due to the limitations of iron printing equipment and process environment, as well as the influence of substrate, ink and other factors, tinplate printing products have been suffering from low color saturation, small color gamut range, poor pattern reduction, easy point deformation, and more difficult to control accuracy and color difference than other printing products for a long time. In order to truly reproduce the original image style, a high-definition, wide color gamut High Fidelity metal printing technology came into being

at the end of the 1990s, Pantone in the United States, visu in the Netherlands, LTG in the United Kingdom, b+k in Germany, greo in Canada, xpose in Switzerland and others have successively developed high-definition, high-level image reproduction effects and high fidelity color printing technology to expand the range of color gamut. This technology is a highly realistic color printing reproduction technology with the original, which is called the fourth generation printing technology. Adhering to the principles of resource integration, independent innovation and environmental protection, the core of the fourth generation printing technology is to use the latest achievements of computer information and image processing, and appropriately use modern ink technology to achieve high-definition and wide color gamut high fidelity iron printing. Generally, when the AM is above 200lpi and the FM is 2540dpi, 2 × 2 the printing of the following points is called high definition printing. The area of 350 line points is one quarter of that of 175 line points. Obviously, finer points can better express the details in the image, thus greatly improving the visual clarity

generally, image reproduction with super 4 colors (5-7 colors) is called wide gamut printing. Due to the wide color gamut, it is closer to spot color than four colors in terms of color purity, saturation, brightness, etc. The combination of high-definition printing and wide color gamut printing produces a high fidelity printing effect, which shows the following advantages:

1) bright colors, bright colors and good lightness

2) clear, soft and strong texture

3) rich levels of dark tones, especially for the parts that are difficult to reproduce conventional four colors such as fluorescent color

4) in multi variety block printing, spot color is required for the reproduction of large-area bright tone background color. The new technology can not only better solve the visual thick printing, but also take into account the color concentration of other levels, which is conducive to reducing the use of spot color

5) it has obvious printing anti-counterfeiting function, and produces excellent anti-counterfeiting effect through color first-line anti-counterfeiting, dot second-line anti-counterfeiting and comprehensive anti-counterfeiting. The color first-line anti-counterfeiting is to formulate and adjust a super gamut area as the anti-counterfeiting area according to the needs. The instructions for the use of Jinan assay drop tester realize the customer specific anti-counterfeiting purpose of anti duplication and anti scanning. Point second-line anti-counterfeiting is to express the same color through the change of the size, number and shape of points, so that the authenticity can be easily identified with the help of magnifying glass and other tools. Comprehensive anti-counterfeiting is the organic combination of color anti-counterfeiting and dot anti-counterfeiting to achieve personalization, differentiation, eye-catching and improve the effect of attention

6) greatly improves the accuracy and timeliness of prepress processing, and is suitable for prepress processing of remote customers and foreign orders

COFCO Meite and Beijing jiayitianshi Electronics Co., Ltd. with the help of the laboratory engine, inject the high-definition and wide color gamut technology and products jointly developed by the reinforced fiber plastic company, assuming that the motor runs and the piston rod does not move, high fidelity iron printing technology and products are based on the traditional iron printing process, making full use of the latest computer image processing technology, color accurate measurement and control technology, printing process parameter optimization and adjustment technology By means of ink analysis and processing technology, we have broken through the traditional 175lpi four-color printing iron to reach 350lpi ultra four-color high-definition wide color gamut printing iron, making the printed image level more delicate, richer, and more bright colors. It has taken an important step to promote China's traditional iron printing to modern digital iron printing and finally realize the technological high-speed production of four-color, six color and multi-color one-time continuous iron printing, and narrow the gap with foreign countries. Its high fidelity products are first popularized and applied in the high-end metal container market, boutique engineering and related industries, especially in the packaging of beverage cans, milk powder cans, miscellaneous food cans, moon cakes, chocolate, candy and paints, coatings, cosmetics, craft gift boxes and metal bottle caps with high decorative requirements

this technology has passed the ministerial appraisal in December 2003, and the expert appraisal committee unanimously passed the appraisal of "high definition and high fidelity technology and products" of Hangzhou COFCO Meite container Co., Ltd. It is believed that the new generation of metal printing technology suitable for China's national conditions enables the majority of end customers to enjoy the beauty of high fidelity. It is expected that this method of leading the new trend of printing technology will soon be promoted in the field of metal packaging, providing technical support for China's metal packaging to enter the world
