Development trend of new technology for packaging and printing metal containers
The metal packaging market is rich and colorful, on the one hand, it is a traditional packaging container, and more importantly, its vitality brought about by the continuous improvement of product value and product manufacturing process. A better company has grown from producing food cans, candy cans, biscuit cans and industrial containers to manufacturing high-performance containers such as spray cans, beverage cans, cosmetics and even leading the market for perfume packaging. Packaging container. At the same time, the exquisite and beautiful metal cover has created business opportunities in metal and non-metallic packaging and poses a threat to traditional packaging methods.
Promoting the current metal packaging market is the product's aesthetics, convenience, value and performance. The environmental protection of packaging materials has become a focus of attention, which requires designers and manufacturers to use new technologies to meet market requirements.
First, the variety 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 shape of the shape is inferior, the strength, integrity, pressure resistance of metal materials is not a problem, but modern packaging Material diversity is more attractive to designers and salespeople. The beverage market is highly competitive. But still the biggest is the metal packaging user. For the UK, 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. On the shelves of the supermarket, we can see many well-known brands, which are packaged with cans with concave and convex, beautiful appearance and beautifully printed. Stelle
Artois, Carling, Catlsbeg and Heineken, familiar brands, seize the opportunity to improve the packaging image through technological advancement. ?
Worldwide, advanced forming technology creates opportunities for the variety of packaging shapes, and the use of forming cans is not limited to beverage packaging and is used in the health drinks and beauty markets. In this respect, the appearance impression and the quality impression are equally important, so there is an artistic shape, a decorative aerosol can begins to appear, and multiple necking techniques are used to form the top and bottom of the can and the can body of any shape.
Second, the progress of printing technology
The constant demand for appearance and brand differentiation encourages the use of new printing technologies and more color printing technologies. The most striking thing is the use of the Hexachrome system, which uses six colors to meet the needs of the chromatogram, and with the precision of the printing process, the quality of metal printing is greatly improved, such as aerosol cans, paint cans and beverage cans. technology.
In the late 1990s, Pantone in the United States, VISU in the Netherlands, LTG in the UK at the beginning of the new century, B+K in Germany, Greo in Canada, and Xpose in Switzerland developed high-definition, high-image-level reproduction and high-fidelity in the extended gamut range. Color printing technology, this technology is a highly realistic color printing reproduction technology with the original, called the fourth generation printing technology. At the heart of the fourth generation of printing technology is the use of the latest in computer information and image processing, the appropriate use of modern ink technology to achieve high-definition and wide color gamut high-fidelity printing iron. Printing using an amplitude modulation network of 200 Lpi or more and a frequency modulation of 2540 dpi and a dot size of 2 × 2 or less is generally referred to as high definition printing. The 350-line dot area is one-fourth of the 175-line dot area. Obviously, the finer dots can more clearly express the details in the image, which greatly improves the visual clarity.
In China, this high-end and excellent printing technology, with the joint efforts of Beijing Jiayi Electronic Technology Co., Ltd. and many technical experts, developed a mature complete set of technical products in 2002 and passed the Chinese printing and equipment. The unanimous signing of experts from the Industrial Association, China Printing Technology Association and the Press and Publications Quality Supervision and Inspection Center of the General Administration of Press and Publication. This technology solves the two problems of the difference in the characteristics of the recorded originals in the conventional printing and the fact that the four-color color space is much smaller than the color space of the reflected light of the scene in the high-fidelity printing technology. Because the high-fidelity printing color separation technology visually senses the color brightness, by regulating the printing neutral gray component; to enlarge the printing color space and map the perceived color saturation, so that the printed image effect is closer to the actual scene observation effect, from this In effect, high-fidelity printing technology is a symbol of a new era in the history of printing technology development; this technology will certainly promote the development and application of fine printing, personalized color printing, and color security printing.
In May 2003, Hangzhou COFCO Meite Container Co., Ltd. signed the application of the project technology. In July of the same year, it began to enter the technical application stage. In August, the production application passed the expert acceptance. In December, it passed the ministerial appraisal. The expert appraisal committee unanimously passed the Hangzhou appraisal committee. Identification of “High Definition High Fidelity Technology and Products†by COFCO Meite Container Co., Ltd. The use of high-fidelity color printing technology and high-definition printing technology on printed iron container products has greatly improved product quality and increased profit growth. According to the company's calculation, due to the adoption of the above technology in the production of printed iron containers, it is planned to create a profit of 16 million yuan in three years.
The high-definition, wide color gamut, high-fidelity printing iron technology and products are based on the traditional printing iron technology, making full use of the latest computer image processing technology, color precision measurement and control technology, printing process parameter optimization and adjustment technology, ink analysis and processing technology, etc. The traditional 175Lpi four-color printing iron reaches 350Lpi ultra-four-color high-definition wide color gamut printing iron, which makes the printed image layer more delicate and richer, and the color is more vivid and bright. It is an important step to promote the high-speed production of traditional Chinese printing iron to the modern digital printing iron and finally realize the four-color, six-color, multi-color one-time continuous printing iron, and narrow the gap with foreign countries. Its high-fidelity products are first promoted in the high-end metal container market, fine engineering and related industries, especially beverage cans, milk powder cans, food miscellaneous cans, moon cakes, chocolate, candy and decorative paints, coatings, cosmetics, craft gifts. It is used in packaging such as boxes and metal caps.
