Metal container packaging printing new technology

The metal packaging market is rich and colorful. On the one hand, it is a traditional packaging container. What is more important is the vitality brought about by its continuous improvement in product value and product manufacturing process. A better company has grown from producing food cans, candy cans, cookie jars, and industrial containers to manufacturing high-performance containers such as spray cans, beverage cans, cosmetics, and even leading the market for perfume packaging. Packaging containers. At the same time, elaborate and beautiful metal covers have created business opportunities in metal and non-metallic packaging and pose a threat to traditional packaging methods.

The current enthusiasm for the metal packaging market is the beauty, convenience, value, and performance of the products. The environmental issues of packaging materials are also becoming the focus of attention. This requires designers and manufacturers to use new technologies to meet market requirements.

First, the diversification of materials
Iron and aluminum as packaging materials, the advantages are well-known, but compared with new materials, such as plastics, composite materials, metal materials in the appearance of the formation of the inferior color, metal material strength, integrity, pressure resistance is not a problem, but the modern packaging The diversity of products is more attractive to designers and salespeople. The beverage market is fiercely competitive. But still the largest is metal packaging users. In the United Kingdom, about seven or eight billion cans were used last year. The role of the brand is very important here. People use various means to attract the attention of consumers. We can see many famous brands on the shelf of supermarkets. They use cans with concave-convex, beautiful appearance and beautifully printed cans as packaging. Such familiar brands as Stelle Artois, Carling, Catlsbeg and Heineken seize the opportunity to improve the packaging image through technological advancement. 

Globally, advanced forming technologies have created opportunities for diversifying the shapes of packages. The use of cans is not limited to beverage packaging and is used in the health drinks and cosmetics market. In this respect, appearance impressions and quality impressions are equally important, so there are art styles, decorative aerosol cans are starting to emerge, and multiple necking techniques are used to form the top and bottom of cans and cans of any shape.

Second, the progress of printing technology
The constant demand for appearance impression and brand differentiation encourages the use of new printing technologies and more color printing technologies. What attracts most attention is the use of the Hexachrome system, using six colors to meet the chromatographic needs, with sophisticated printing plate production process, so that the quality of metal printing is greatly improved, such as aerosol cans, paint cans, beverage cans use this new technology.

In the late 1990s, Pantone in the United States, VISU in the Netherlands, LTG in the United Kingdom in the beginning of the new century, B+K in Germany, Greo in Canada, Xpose in Switzerland, etc. have successively developed high fidelity with high definition, high image-level copying effect, and expanded color gamut range. Color printing technology, this technology is a highly realistic color printing replication technology with the original, called the fourth generation printing technology. The core of the fourth-generation printing technology is to use the latest results of computer information and image processing, and to use modern ink technology to achieve high-definition and wide-gamut high-fidelity printing iron. Generally, the use of the amplitude modulation network above 200 Lpi and the frequency modulation of 2540 dpi, and the printing of dots below 2×2 is called high definition printing. The area of ​​350 lines is one quarter of the area of ​​175 lines. Obviously, the finer lines can more clearly express the details in the image, so that the visual clarity is greatly improved.

In China, this high-end, excellent printing technology under the joint efforts of Beijing Jiayi Tianshi Electronic Technology Co., Ltd. and many technical experts, in 2002 developed a mature set of technical products, and passed China's printing and equipment equipment. Industrial Association, China Printing Technology Association, Press and Publication Administration of the printing product quality supervision and inspection center unanimously signed experts. This technology has solved the problems of the difference in the original characteristics of the recorded documents in the conventional printing and the two problems that the four-color color space is much smaller than the color space of the reflected light of the scene, and has been solved uniformly in the high-fidelity printing technology. Because high-fidelity printing color separation technology visually perceives color brightness by regulating the neutral grey component of the printing; expanding the printed color space and mapping the saturation of the perceived color, the printing image effect is closer to the observation effect of the actual scene, from this In effect, high-fidelity printing technology is a sign of a new era in the history of printing technology; this technology will certainly promote the development and application of exquisite printing, personalized color printing, and color security printing.

In May 2003, Hangzhou Zhongliang Meite Container Co., Ltd. contracted to apply the technology of this project. In July of the same year, it entered the stage of technological application. In August, the production application passed the acceptance of experts, and in December it passed the ministerial appraisal. The expert appraisal committee unanimously passed Hangzhou. The identification of "high-definition and hi-fi technology and products" of COFCO Meite Container Co., Ltd. The use of high-fidelity color printing technology and high-definition printing technology on the printed iron container products has greatly improved product quality and increased profit growth. The company estimates that due to the above technology used in the production of printed iron containers, it plans to create a profit of 16 million yuan in three years.

The high-definition, wide color gamut, high-fidelity iron printing technology and products are based on the traditional iron stamping process, making full use of the latest computer image processing technology, precise color measurement control technology, optimization of printing process parameters adjustment, ink analysis and processing techniques, etc. Traditional 175Lpi four-color printing iron, up to 350Lpi ultra-high-definition wide color gamut printing four-color, so that the printed image level more delicate, more abundant, brighter and brighter colors. It has taken an important step towards promoting the high-speed, process-oriented high-speed production of four-color, six-color, and multi-color one-time continuous printing iron by promoting the traditional printing of iron from China to modern digital printing. Its high-fidelity products are first popularized in the high-grade metal container market, fine engineering and related industries, especially beverages, milk powder cans, food miscellaneous cans, moon cakes, chocolates, candy, and paints, coatings, cosmetics, and craft gifts that require high decoration. Applicable to packaging such as boxes and metal caps.
