The material carriers of printed matter, calligraphy and painting are mostly paper, and the color information is used to express the pattern text information. With the support of the National Science and Technology Support Program, Beijing Green Printing and Packaging Industry Technology Research Institute has carried out long-term basic research and applied research on printed materials, calligraphy and painting materials, and has achieved a series of innovative results.
According to reports, research on printing, calligraphy and painting materials has important application prospects. Taking the printing method of copying and imitation of calligraphy and painting as examples, there are mainly various techniques such as traditional woodblock watermarking, collotype, offset printing and micro-spraying. Since the end of the Qing Dynasty, a large number of calligraphy and painting works have been reproduced and imitated, especially high-quality imitations such as Colo edition, offset printing, and micro-spraying. The colorants of calligraphy and print reproductions such as Coro, offset, etc. belong to the oil-based ink system, which is generally prepared from oil-soluble substances and natural or artificial pigments. This is quite different from the water-based ink used in calligraphy and painting. Technology can identify these printed copies and imitations.
In addition, studying the materials for the production of prints, paintings and calligraphy works, on the one hand, you can learn about the material composition, production technology and other information. On the other hand, you can also get some information about the era of the prints, paintings and calligraphy, such as Prussian blue, Paris green, etc. The pigment can provide a basis for the dysplasia of printed matter, calligraphy and painting, so the analysis of printed or calligraphy and painting materials can also identify some imitations, replicas and restorations. For damaged prints or calligraphy and painting works, material analysis can also provide guidance for its protection and restoration.
At present, the laboratory of Beijing Green Printing and Packaging Industry Technology Research Institute is equipped with advanced equipment such as micro laser confocal Raman spectrometer, scanning electron microscope-energy spectrometer, three-dimensional ultra-depth video microscope, and advanced non-destructive analysis technology of materials at home and abroad. A large number of paper identification, ink / ink / print ink / oil identification, pen / sign pen / marker ink identification, etc.
