High fidelity printing: the driving force to promote high-end packaging

high fidelity printing technology can only be used or may be more used in the field of packaging and printing, which has been circulating for a long time. It is understandable if a printing master or a business person holds this view. However, experts and professors in the printing industry still understand this today, which may really need to be taken seriously. This article can make readers fully realize the real difference between high definition and high fidelity in definition and Application

packaging printing materials pay more attention to the performance of color, because attracting people's attention is one of the important functions of packaging. However, the color of a considerable part of the packaging is the color of field, flat, gradient printing. For logo colors beyond the four-color printing gamut, designers choose to use light colors to attract attention, or bright personalized colors. At present, the best process choice is still to use spot color printing. Although high fidelity printing can reach the level of spot color in color effect, there is no way to keep the same consistency between printing color and spot color printing under the condition of normal fluctuation of printing process. Similarly, although the visual effect of the light tone combination of high fidelity printing is basically similar to that of light tone spot color printing, it cannot be spread on the surface of the substrate like spot color, and the gloss of the print is visibly different

metal packaging is full of true colors due to high fidelity

the metal packaging market is rich and colorful. On the one hand, it is the traditional packaging container, and more importantly, it is the vitality brought by its continuous progress in product value and product manufacturing technology. A better enterprise has developed from mainly 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 market trend packaging containers for perfume packaging. At the same time, exquisite and beautiful metal covers have created business opportunities in metal and non-metal packaging, and pose a threat to traditional packaging methods

what drives the vitality of the current metal packaging market is the beauty, convenience, value and performance of products. The environmental protection of packaging materials has increasingly become the focus of attention, which requires designers and manufacturers to meet market requirements with new technologies

diversification of materials

iron and aluminum as packaging materials have well-known advantages, but compared with new materials, such as plastics and composites, metal materials are inferior in appearance, and the strength, integrity and pressure resistance of metal materials are not a problem, but the diversity of modern packaging materials attracts the attention of designers and salesmen. The competition in the beverage market is fierce. But still the largest is the metal packaging users. For Britain, about seven or eight billion cans were used last year. The role of brand is very important here. People have used various means to attract the attention of consumers. We can see many well-known brands on the shelves of supermarkets, which are packed in cans with concave convex feeling, beautiful appearance and exquisite printing

globally, advanced forming technology has created opportunities for the diversification of packaging shapes. The use of shaped cans is not limited to beverage packaging, but also used in the health drinks and beauty products markets. In this regard, the appearance impression and quality time are mostly 15 (4) 5 days. The quantity impression is equally important. Therefore, there are artistic modeling, decorative aerosol cans begin to appear, and multi-channel necking technology is used to form the top and bottom of cans and arbitrary shape of cans

the progress of printing technology

the continuous demand for appearance impression and brand difference encourages the use of new printing technology and more color printing technology. The most noteworthy is the use of hexachrome system, which uses six colors to meet the needs of chromatography, combined with the precise printing plate making process, so that the quality of metal printing can be greatly improved, such as aerosol cans, paint cans, beverage cans are using this new technology

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. The core of the fourth generation printing technology is the use of the latest achievements of computer information and image processing, and the appropriate use of modern ink technology to achieve high-definition and wide color gamut high fidelity printing iron. 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

in China, with the joint efforts of Beijing jiayitianshi Electronic Technology Co., Ltd. and many technical experts, this high-end and excellent printing technology developed a mature set of technical products in 2002, which was unanimously signed by experts from China printing and equipment industry association, China Printing Technology Association and the printing product quality supervision and Testing Center of the General Administration of publishing. This technology makes the two problems that the characteristics of the recording manuscript in the traditional printing are different and the four-color color space is much smaller than the color space of the reflected light of the scene unified in the high fidelity printing technology. Because the color separation technology of high fidelity printing perceives the color brightness visually and regulates the neutral gray component of printing; By expanding the color space of printing and mapping the perceived color saturation, the effect of printing image is closer to the observation effect of the actual scene. From this effect, high fidelity printing technology is the symbol of a new era in the history of printing technology development; This technology will surely promote the development and application of exquisite printing, personalized color printing and color anti-counterfeiting printing

in May 2003, Hangzhou COFCO Meite container Co., Ltd. signed a contract to apply the technology of the project, and began to enter the technical application stage in July of the same year. The production and application passed the expert acceptance in August, and passed the ministerial appraisal in December. The expert appraisal committee unanimously passed the appraisal of "high definition and high fidelity technology and products" of Hangzhou COFCO Meite container Co., Ltd. The use of high fidelity color printing technology and high-definition printing technology in iron printing container products has greatly improved product quality and increased profit growth. According to the calculation of the company, due to the adoption of the above technology in the production of iron printing containers, the company plans to create a profit of 16million yuan in three years

based on the traditional iron printing process, this high-definition, wide color gamut, high fidelity iron printing technology and products make full use of the latest computer image processing technology, color accurate measurement and control technology, printing process parameter optimization and adjustment technology, ink analysis and processing technology and other means to break through the traditional 175lpi four-color iron printing, to reach 350lpi ultra four-color high-definition wide color gamut iron printing, so that the printed image level is more delicate and richer, The colors are more bright and bright. It has taken an important step to promote the technological high-speed production of China's traditional printing friction small iron to modern digital printing iron and finally realize the four-color, six color and multi-color one-time continuous printing iron, 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

application scope of high fidelity printing technology

even if more spot colors are selected, the ideal effect cannot be directly printed. It is color images. The points used in image printing cannot be completed by drawing method. The only way is to use a color separation system. Here, high fidelity color separation technology can fully show irreplaceable advantages

stamp printing adopts new primary color ink, adjusts and controls the gradient curve, and depends on the experience of the master. The reproduction of famous paintings and printmaking also need to add new primary color inks. Even if collotype printing, negative copy and revision must be used to prepare the printing plate for the new printing base color. Color separation based on experience may take a long time, and it is difficult to ensure the printing quality. The high fidelity color separation system is completed with the help of computer technology according to the principle and technology of colorimetry. It is equivalent to integrating the successful experience of many masters, so that the color separation process can be completed automatically and quickly, and can maintain the consistency of countless repetitions, reaching the highest level of printing quality at present. Horizontal tensile testing machine can not do things

printing copy image, for a long time, the gradient characteristics of brightness have been ignored. As a true record of natural scenery, images, including the artistic creation effect of photographers, as well as images created by computers, the spatial sense of visual perception and the change of color, to a large extent, depend on the role of color brightness. Photographers know that the grasp of light is the first element of photographic works. Chromatic significance of color brightness is the measurement of light

high fidelity color separation technology, in fact, follows the principle of colorimetry, and regulates color saturation and color brightness respectively in a uniform color space. To increase the base color ink, expand the printing color gamut, and adjust the color saturation of the printing color according to the interval of visual perception color saturation. According to the gradient linearity of visual perception brightness, adjust and control the amount of neutral gray in printing, so as to ensure the spatial sense and color relationship of printed images, which are closer to the real scenery of nature

most people see high fidelity printing, and there are many bright colors that are not available in conventional four-color printing, so they are deeply impressed by the expansion of printing color gamut. They often ignore the linear change of color brightness. They didn't realize the fundamental reason why the printing effect is more vivid and the sense of space is stronger. Because the amount of neutral gray is reasonably controlled, more color ink components can be used below the middle note than four-color printing. The darker part of the image can display more colors, so the image is more vivid and realistic. These colors are within the range of conventional four-color printing gamut. The change of printing effect is not due to the expansion of printing gamut, but the result of linear regulation of color brightness

almost all images, even if they do not need to expand the printing color gamut, must be printed and copied according to the effect of human visual perception brightness. Unless they don't know how to achieve this effect. The currently developed high fidelity color separation system includes a model using conventional four-color ink for color separation. The printing color gamut is the same as before, and the color brightness gradient linearity is consistent with the human visual perception effect

introduction at this point, readers can clearly understand the scope of application of high fidelity printing. It can not only be used for packaging and printing, but also for all printing enterprises mainly engaged in image printing. Of course, the premise of application is still that it needs the effect of high fidelity printing, whether it is a larger printing color gamut or a color brightness gradient curve consistent with the visual perception effect

will the charge for high fidelity printing products rise several times? Such sensational speculation out of thin air will undoubtedly scare many wait-and-see users. Anyone with a little common sense knows that the cost of printing media generally accounts for about two-thirds of the fees for printing more than tens of thousands of copies, except for the process fees for decoration. High fidelity printing actually increases several primary color materials, machine time
