Tinplate high-fidelity color printing process
The high-definition high-fidelity color printing complete set of technical process research project was hosted by Beijing Jiaji Tianshi Electronic Technology Co., Ltd., and was approved by the Science and Technology Small and Medium-sized Enterprise Technology Innovation Fund Management Center of the Ministry of Science and Technology in November 2000. Project code: 00C26211100683 , Ministry of Science and Technology, Ministry of Finance approval number: National Branch issued the word (2000) 473. The project was awarded an innovative fund of RMB 800,000 yuan.
I. Product R&D and Application In October 2002, the technical appraisal of the project's research results was held in Beijing. The appraisal meeting was presided over by the China Printing and Equipment Equipment Industry Association. Vice President Yang Jinghua and Deputy Director Wang Demao of China Printing Technology Association, National Print and Information Quality Supervision and Inspection Center, Beijing Institute of Graphic Communication and Beijing Institute of Technology Senior Vice Presidents Gao Yongqing, Tan Junyi, Guan Zhixiang, Director Li Jiaxiang, Professor Chen Shiwen, Liu Haoxue, and Professor Jiang Yuejuan attended the event. The experts agreed that “the project has many innovations in the same research in the country and the research results have reached the international advanced level. It is suitable for the printing industry, especially high-end albums for packaging and commercial printing companies and companies engaged in anti-counterfeit printing. Quality color print companies have a high application value. Experts have passed the project technical appraisal.â€
In May 2003, Hangzhou Zhongliang Meite Container Co., Ltd. signed and applied the technical achievements of the project. In July of the same year, the application of technology was started. In August, the application of production was approved by experts. The acceptance expert group was headed by Li Jiaxiang, senior engineer of the General Secretary of the National Printing Standardization Technical Committee; Liu Haoxue, Research Associate, School of Printing and Packaging Engineering, Beijing Institute of Graphic Arts; Vice Chairman; and experts from Zhejiang, Hangzhou, and Factory Technical Committees. Together. Acceptance experts spoke highly of the work report and dozens of prototypes produced.
In December 2003, new products produced by users using this technology passed the expert appraisal organized by China Packaging Corporation. The appraisal opinion is as follows: The application of this technology to the printed iron industry is a technological innovation that enables the company to be in a leading position in the domestic industry. Under the existing production conditions of the company, the application of this technology can significantly improve the product quality, expand the scope of application of the product, increase the added value of the product, and have good economic and promotional value. Through trials and trial production, this study can be applied to scale production and can guarantee the stability of product quality. The technology uses 5-7 colors 200-350lpi printing proofs and customer products, compared with conventional four-color 175lpi printing proofs and products, the image sharpness is obviously improved, the fine level is improved, and the visual roughness caused by the rose spots after overprinting is significantly weakened. The printing color gamut has been significantly increased, the range of tone adjustments has increased, the printing colors have become brighter and more saturated, and the levels have become more abundant, with a stronger sense of three-dimensionality. High-definition and high-fidelity technologies and products can reduce the use of spot color ink under certain conditions, and have a good anti-counterfeiting effect in the printed iron industry. The expert appraisal committee unanimously passed the appraisal of “High-Definition and Hi-Fi Technology and Products†of Hangzhou Zhongliang Meite Container Co., Ltd.
In April 2004, entrusted by the Innovation Funding Center of the Ministry of Science and Technology, the Beijing Science and Technology Commission organized experts to carry out acceptance of the project.
Second, product technical points
The high-definition, high-fidelity and color printing complete set of technological processes is the technological achievement that has been simultaneously researched and led by the international community. Its innovative research and application of color reproduction theory and control technology can greatly improve the quality of color prints. It has provided new technical support for the design and production of medium and high-grade printed matter, created a color anti-counterfeiting printing technology process, and has no special requirements for existing related equipment. Products are delivered to customers in the form of computer software systems and applied to the prepress color separation process. The technical service provided at the same time with the product can guide the process operations of proofing and printing, and complete the production of high-definition and high-fidelity color printing products.
Third, product technology value
With the development of economy and culture, society has always put forward higher requirements for the quality of printed matter. In the market demand, the printing industry's equipment, materials and process technology are also continuously improving. Printing companies should open up and expand their markets, guide and develop customers, and must have innovative perspectives and strategies. One step ahead of the application of new technologies, improve product quality, and increase profit growth points are conducive to accelerating progress on the road of sound and sustainable development.
In recent years, high fidelity color printing technology has become one of the main research contents in the international printing field. The high-fidelity color printing technology completely breaks the limitations of the four-color printing color gamut and creates a brand-new expression of color expression. It is starting to become the mainstream process technology and quality standard for high-end color prints. High-fidelity color printing technology can greatly expand the printing color gamut, make the prints more colorful and natural, and closer to the natural world visible color and three-dimensional, able to show the color that conventional printing technology can not reproduce. Due to the exclusive features of the optional ink and color separation model and neutral gray balance model design, the high-fidelity color anti-counterfeiting complete set technology has become a high-efficiency, low-cost anti-counterfeit means, and has great commercial value.
