Overview of high simulation technology of digital printing

I. high imitation products of digital printing caused a sensation in Beijing

in July 2005, Beijing was in the heat of summer. People went to Beijing dongzhimenwai happiness Art Center to enjoy the Forbidden City simulation art exhibition jointly organized by Beijing shengcaihong plate making and Printing Co., Ltd. (hereinafter referred to as shengcaihong) and Beijing yidingxuan culture company, and felt the coolness brought by classical culture in the hot summer

with advanced digital printing technology, shengcaihong realizes the perfect reproduction of the treasures of classical culture, and copies many famous paintings one by one according to the original in terms of size, texture, ink and color, making people feel like enjoying the satisfaction and pleasure of authentic works. Mr. Xu Bangda, a leading figure in the field of cultural relics identification, praised these works as "well printed and almost unreal"

then in August, at the first "keyin Cup" digital printing works Grand Prix, the series of "calligraphy and painting imitations collected in the Forbidden City" copied by shengcaihong was awarded the grand prize. Judges' comments: this series of works is an organic combination of new materials (coated rice paper and silk) and new processes (digital inkjet technology HCC color management) in the reproduction of ancient calligraphy and painting, which has raised the simulation reproduction to a new level. It not only achieves "similarity in shape", that is, the dry and wet ink rhyme is displayed appropriately, the color configuration corresponds to the color matching of traditional Chinese painting, the texture of rice paper and silk is like an authentic work, but also achieves "similarity in words", which maintains the charm of the original work and reflects the connotation of the work

at the third Asian printing Grand Prix, which was announced in Bangkok, Thailand, in November, St. rainbow's reproduction of "highly simulated lotus mandarin duck picture of calligraphy and painting collected in the Forbidden City" and "oil painting simulation of Jin Shangyi oil painting" jointly won the gold medal for printing quality of inkjet digital printing. Judges' comments: the level of digital printing simulation art is amazing

the above series of activities have caused a sensation among artists, collectors, art lovers, publishing and printing circles and media in Beijing. Mr. Yang Xin, the retired former vice president of the Palace Museum and a famous cultural relics appraiser, believes that the first-class national cultural relics replicas supervised by the Palace Museum are of great value in terms of both the significance of art appreciation and the preservation and appreciation of collection, because of their superb simulation technology and limited sales. As soon as the high-quality imitation of national calligraphy and painting in the Forbidden City comes out, it will attract the attention of collectors and enthusiasts and become a hot collection

as an old printing worker who has been engaged in printing and reproduction for 58 years, seeing these works of art with advanced digital printing technology to achieve high simulation reproduction, I am very happy and excited. These works of art have realized the ideals pursued by generations of printers, so that people can enjoy the painting treasures hidden in the deep Pavilion for hundreds of years. Seeing authentic works of art is not only a great enjoyment to appreciate works of art, but also an opportunity to analyze fine print

second, a variety of simulation technologies play a different role

in order to better simulate and reproduce China's calligraphy and painting treasures, several generations of printing reproduction workers have made arduous efforts, constantly exploring, researching and practicing, using different printing processes and different printing materials for simulation reproduction, and there are new developments and improvements in each historical stage, approaching the original effect step by step. In fact, modern digital high simulation replication technology is also the inheritance and development of China's traditional simulation replication technology. For example:

1 Recently, the "Keluo plate" photosensitive plate, which reflects the level of printing technology more than 80 years ago, was first discovered in Jinan, which was a relatively advanced technology at that time. It is a photosensitive plate based on glass and coated with a layer of photosensitive glue dissolved by dichromate and gelatin. After close contact with photographic negatives and exposure (printing), it is made into a plate for printing. It is mostly used for printing precious pictures, paintings, inscriptions and so on

the characteristic of collotype printing is that it can be lifelike and vivid, retain the charm of traditional Chinese painting, and can be printed in a certain amount. However, its plate making technology is very demanding, mainly relying on manual sketching. Without superb plate making skills, it is difficult to copy with high quality

2, the woodblock watermark of Beijing rongbaozhai is a unique set of traditional printing technology in China. It is a kind of gripping of the original sketch sample, which is a very important link and plate division in the test process. Several chromatic plates are carved on the hardwood and overprinted with rice paper and water-soluble pigments one by one. It can reproduce the original realistically and is still loved by people today. However, due to manual operation, long production cycle, high cost and difficult process technology, it can only be used as a few boutique printing

3. With the progress of technology, the advantage of using offset technology to simulate reproduction is that it can be printed in batches. Therefore, since the 1950s, Chinese printing workers have continuously studied and practiced, making the replication of national treasure calligraphy and painting to a high degree of simulation. For example:

① in 1959, Beijing Xinhua printing factory printed a large-scale high-end album "China" when celebrating the tenth anniversary of the founding of the people's Republic of China. As an innovative technology presented by the factory, it used photographic color separation and offset printing technology to print on Rice paper, and printed a picture of "Xiangfei" with 8-color technology. It was successful, and was praised by the editor in chief liaochengzhi

② 1201 factory and China printing company have specially organized scientific and technological personnel to carry out research and production. The rice paper simulation traditional Chinese painting using electronic color separation and offset printing technology has printed many paintings collected in the Forbidden City and the calligraphy and painting art of modern famous painters, raising the simulation degree to a new level

③ since the 1950s, shanghai art printing factory has been studying and practicing the limited printing of rice paper imitation traditional Chinese paintings with offset printing technology, and has successively printed more than 100 kinds of paintings collected in Shanghai Museum and the representative works of modern famous painters, which has won international gold awards for many times. They printed on rice paper with 3001pi lines that exceeded visual recognition, maintaining the charm of the original. In the south, there was a eulogy that "if you print Chinese paintings well, you should go to the art factory"

. In the 1980s, Shenzhen Tianming art printing company carried out in-depth research and produced a series of products of "rice paper and traditional Chinese painting simulation printing", which have been improved both in terms of process technology and simulation degree. Moreover, they applied for patents with new ideas and new methods of printing on rice paper, and made contributions to the commercial operation

⑤ at the same time, it has to be mentioned that Shenzhen Huaxin plate making printing company, which uses rice paper to simulate traditional Chinese paintings to make excellent achievements ⑤ APM calculation formula brush company, has copied many famous paintings with high simulation degree, which has been highly praised by painters and printing circles. They make full use of a variety of shades of black and gray to express the charm of traditional Chinese painting, and make full use of the three primary colors and the method of configuring spot color plates to expand the color space range, so that it corresponds to the special colors of traditional Chinese painting, reaching a new height of the simulation and replication of offset printing technology on rice paper

⑥ in the field of imitation art reproduction abroad, Japanese erxuan society is the most famous. The offset printing technology developed by the agency in cooperation with the National Palace Museum in Taipei has achieved a high level of imitation reproduction of ancient paintings and enjoys a high reputation. Its features: first, a special camera is used to shoot high-precision, high-quality and large-size color reversal films on site; Second, special paper and silk cloth are used; Third, the use of computer plate making, the use of color spot color plate for color matching overprint; Fourth, 3001pi high-speed printing is adopted to achieve the consistency with the continuous tone feeling of ink painting; Fifth, 1:1 original size reproduction, through mounting, is inseparable from the original

to sum up, printing workers at home and abroad have made unremitting efforts for the reproduction of highly simulated works of art, but due to the limitations of process technology, its technology is difficult, the process is complex, the production cycle is long, the cost is high, and there are still some imperfections that need to be further developed and studied

third, the high simulation technology of digital printing takes the lead

modern high technology has raised the simulation and reproduction level of national treasure calligraphy and painting collected in the Palace Museum to an unprecedented level, so that the perfect reproduction of cultural treasures can be achieved in a simple and fast way. Through high imitation, more treasures of the Forbidden City will go out of the "boudoir" to meet the people, further reflecting his cultural value. At the same time, more people can recognize the top art at a temperature very close to the melting point of ordinary aliphatic polyamide, learn more about Chinese traditional culture, and improve the level of art appreciation and their own cultural taste

shengcaihong creatively applies modern advanced digital ink-jet high simulation to copy national treasure calligraphy and painting, which has made an important contribution and provided us with many new enlightenment and fresh experience to promote and apply this new technology. There are five characteristics:

1. Using advanced input equipment

input is the first level of replication. You must obtain all the required information from the original when scanning. For this reason, St. rainbow company adopts the large format physical scanner of German cruse company to scan with the original, and its maximum size is 1 8mx LM, with a maximum accuracy of 451dpi. This is a key technology of high simulation reproduction, which can accurately scan the color level information of the original, and provide a high-definition scanned image file for art reproduction, thus reducing the loss of color level information caused by remaking the secondary original and scanning with the secondary original

2. Taking advantage of digital inkjet technology

Epson Pro 9800 digital inkjet machine is selected. One is to take advantage of its frequency modulation. Its 1440dpi frequency modulation can't be seen under a 10x magnifying glass, and the continuity of the tone is very similar to the effect of Luo printing. Second, using the "century rainbow K 3" 8-color pigment ink, its color gamut is wide, the color space is larger than that of ancient paintings, and the color stability is good, which can reach 70 to 80 years without fading. At the same time, it has three colors of black (black, light black, light black) Matching with the ink color of traditional Chinese painting, especially the thick black, the density can reach 2 30. It can fully show the concentration of burnt black printed on rice paper, and light black is conducive to the reproduction of light gray

3. One of the biggest difficulties in developing polymer coating materials

using digital ink-jet printing technology for high simulation replication is how to print on painted rice paper, silk and canvas. There are two kinds of rice paper for painting: raw and cooked. Raw rice paper is easy to seep ink, which is suitable for heavy pens; It's easy to be meticulous. Neither of them is suitable for inkjet printing. If the coating is not specially treated, there will be ink diffusion, dot diffusion, poor definition, and the density will not go up, especially the black ink density is low, and the color saturation is low, so printing cannot be carried out. Only through the special treatment of the coating and mastering the printability of rice paper and silk, can we control the wet and thick ink of traditional Chinese painting represented by ink-jet printing. Therefore, we must first break through the bottleneck of materials. General manager Zhou Xiangli, the scientific research leader of shengcaihong company, led the scientific researchers to consult a large number of materials and look for suitable materials and manufacturers all over the country and overseas. After more than a year of repeatedly testing and modifying the coating formula day and night, a major breakthrough was finally made. A polymer polymer coating that meets the inkjet printing suitability was developed, and advanced nanotechnology was used to make the coating achieve the best graininess, ensuring higher printing density contrast, wider color gamut, and more saturated color. There are three key technologies for coating materials:

(1) the thickness of coating particles The so-called nanotechnology is
