Jielong High-level Hardcover Book Printing and Binding

The "National Treasure" in National Treasure--The Printing and Binding Features of Jie Long's Advanced Hardcover Album

In commemoration of the 50th anniversary of the establishment of the Shanghai Museum, Shanghai Dragon Sakura Color Printing Co., Ltd., a subsidiary of Jie Long Group, and Shanghai Jie Long Printing and Binding Factory (will be renamed to Jie Long Art Printing Co. National treasure special collection (hereinafter referred to as National treasure special collection).

The National Treasure Special Collection is a large eight-page book with a size of 420mm x 305mm, a total of 640 pages, plus an outer box of 11 centimeters thick and weighing 13.5 kilograms. The calligraphy and painting in this special collection is quaint and completely identical to the original display of the original work (only a few are scaled down).

This national treasure collection is the highest level in the quality of plate making, printing and binding. After extensive investigations at home and abroad, the Shanghai Museum has carefully selected seven printing companies to submit bids for the seven printing companies to make copies and proofs. As a result, Long Ying, a subsidiary company of Jie Long Group, came to the fore. The version produced by Sakura Sakura is very close to the original, and the accuracy of the outlets exceeds that of the Boston Museum (hereinafter referred to as “wave map recording”). The network accuracy of the "Porto Record" network outlet is 200 lines, and it is processed in midtones. Long Ying uses CTP technology (that is, frequency modulation screening), with an accuracy of 300 lines or more, almost the same as photos.

The effects of traditional pattern proofing and on-machine printing may cause chromatic aberration due to some uncontrollable factors. Jie Long uses CTP technology for digital printing, which can directly transfer the proofing printing data to the printing machine, ensuring that the proofing and printing effects are completely consistent, and ensuring that the printing at different times is completely consistent, even up to a few meters, across a large number of pages, before and after The effect of printing at different times is exactly the same. For example, Wu Zhen's “Fisher Fisher Chart” in the Yuan Dynasty was 7 meters long and consisted of more than a dozen pages. It was seamless and the color difference did not exceed 1%. Very gratifying is that special collections of printed matter not only imitate ancient paintings with a high reduction rate of almost 100%, but also improve the quality of the original works. Some old paintings are old due to age, the color is degraded, and seals have few imprints. Unrecognized, only by X-ray photography, spectral analysis, can be found in the original colors and prints, and then through the digital modern printing means to be reproduced. Those who saw the original works of the National Treasure Painting and calligraphy in the Shangbo Museum, if they compared her with the National Treasure Collection, would be surprised to find that some of the ancient paintings of the National Treasure Collection were even more vivid, clearer and brighter than the works in the exhibition. The Hong Kong printing expert Mr. Yang Xiaowei, who was involved in guiding the printing of the album, said that I have printed for 50 years and have not seen such a good thing. In the past, I adjusted my color difference by my eyes. Now digital printing has more control than my eyes. The old experience is much more reliable. I opened my eyes on Jie Long Company and learned a lot of new knowledge. As the director of the Liaoning Museum and a member of the Chinese Ancient Calligraphy and Painting Identification Panel, Yang Renyu, commented: “Elaborate printing can confuse truth.”

The National Treasure Collection gathers top technologies for printing in the contemporary world. In the former printing process, Japan, Hong Kong and Switzerland used CTP plate making technology, broadband transmission technology, digital printing in Germany and Japan, and UV polishing equipment. The paper used was Japanese gentleman's paper. . Such a large-scale calligraphy and painting feature is not only difficult to print, but also has a high binding requirement. To this end, Jie Long Printing and Binding Factory specializes in ordering the Asda sewing machine from Italy and airlifts it to Shanghai. In particular, the United Kingdom is required to dye the gutter into a color that is in harmony with the quaint album. The United States has the best spine lining for elastic performance and uses glue with the most suitable toughness and fluidity. After being bound into books, the destructive tests were conducted manually and the pictures were still kept exactly as they were, without any loose and falling phenomenon.

Jie Long successfully cloned the national treasures of ancient paintings and calligraphy, and created the Huang Huang system in the world's top hardcover albums. The market value of the national treasure special collection keeps rising. A total of 2,500 copies of this book were printed, 500 copies of the National Palace Museum and Liaoning Museum, and 1,500 copies of the Shanghai Museum. The price list of 6,000 yuan per book is now hard to find on the market.

The successful printing of this album marks a new level of printing and binding in Shanghai. She has become a "national treasure" proud of the Shanghai Museum. Directors Chen Yijun and Wang Qingfei relished the quality of the album when it was introduced to distinguished guests at home and abroad. Chen Liangyu, secretary of the Shanghai Municipal Party Committee, also presented the album as a precious gift to Premier Zhu Rongji and German Chancellor Schroeder, who was in Shanghai to cut the ribbon for the trial run of the Maglev train. The Finnish President Halonen regarded the book presented by the chairman of the World Dragon Group Federer as a treasure.
