First, the purpose of the construction of the archive simulation work
The simulation of paper archives has deep social, artistic and market value. Everything in the world has a "lifetime", and the archives are no exception. In ancient China, there was a saying that "there are eight hundred guarantees and the paper is a thousand years old." That is to say, even if it is carefully kept, the calligraphy and painting can only be preserved for 800 years, and the paper calligraphy can only be collected for a thousand years. With the advancement of science and technology, although the "life" of archives is prolonged, it will still die, and the best way to continue the life of archives is to copy.
Archives at all levels are trying to use the collections to hold short-term exhibitions of various themes and forms, or to establish long-term archives and exhibitions, so that precious files can be more fully utilized. However, in practice, in order to ensure the security of the original file, the use of "simulation pieces" to replace the original display has become a common first choice. This not only shows the content of the file, but also shows the carrier and decoration of the original file, or an excellent measure to protect the original file. Therefore, the simulation copying technology is used to simulate and copy the file, which protects the original file and provides convenient use. It also fully demonstrates that the simulation copy is not only beneficial to the protection and utilization of the file, but also the extension and extension of the file opening and use. .
Second, the file simulation replication technology
The simulation copy of the file is mainly composed of four technologies: scanning technology, computer image processing technology, color management technology, color management technology called digital process, and output technology, namely inkjet digital printing.
At present, the input devices used in file simulation copying in China are mainly: high-precision simulation scanners of OS12000 series and OS14000 series, because the scanner is very suitable for single-page files, bound books, unremovable ancient books, etc. The data is simulated and copied; and the precision is high and the speed is fast. The A0 format can reach 16.8 seconds/page; the color collection level is very delicate, and the level of subtle color difference can be obtained, so there are many domestic applications.
Zeutschel's latest generation of book scanners with projected, non-glare cold light source technology for all books, archives, maps and drawings that need to be scanned. The low-brightness light source provides extreme protection for valuable books and archives, and the high-precision true color scanning lens perfectly reproduces the real details of the original. The user-friendly design of the number of games provides users with a safe, reliable and ergonomic operating environment.
