New Lithograph Of Alternative Teaching Materials

Lithography, by the German invention of Alois Senefelder. As imported technology, the lithographic development is slow and delay. Lithographic teaching really start in the last century the eighties in China, By the China Academy of Fine Art, China Central Academy of Fine Arts, Lu Xun Academy of Fine Arts, Tianjin Academy of Fine Arts, Hubei Academy of Fine Arts and so on, Establish lithographs professional and lithographs studio to sign.Solnhofen stone, The most ideal Lithographic printing plates. However, due to extensive mining, has led to depletion of this resource. Since the late Ming and early Qing Dynasty, Lithographic printing from entering China. Some people actively looking for alternative sources. Including the re-counties in Liaoning, Hubei, Wuhan, Jiangyou, Sichuan, Yunnan, Dali and other places are trying to alternative rock resource development and utilization. And has been used in teaching stone lithographs plates are:Wuhan, Hubei Songzi Stone, Sichuan Jiangyou stone. To some extent alleviated the lithography stone lacks the status quo. However, because of the color problems, and widely used. In particular, has been issued by the exploitation of the size of Hubei Songzi stone, because of its layout of quick-drying, dry conditions in the north, to the actual printing operation to increase a lot more difficult. Therefore, developing the performance of a Songerhuofen lithography lithography Lithographic stone material, it is very important.Songhua stone, also known as "Songhua Yu." As early as the finest in the Qing dynasty was the ink stone materials, and enjoy a high artistic and social assessment. Called "Yu Yan", "national treasures." Songhua stone lithography stone study is based on its similarity with the geological formation of Solnhofen stone reasons, geological formation environment, comparative analysis between the two chemical elements, physical properties, and through Lithographic printing experiments have confirmed that the Songhua stone printing basic performance. Its main ingredients are microcrystalline calcite component. Its thickness, density, water absorption are related to similar Solnhofen stone. Chemical composition of calcium carbonate and calcium oxide can be converted with water. Therefore, an alternative Solnhofen stone and Songhua stone in lithography with possible and operational.Songhua stone lithography on the basis of techniques to test:pencil, tusch, asphalt, oil, etc. In the end. Test Songhua stone around the foundation stone with Solnhofen performance were analyzed. As well as the formation of image analysis and comparison of effects. For the ink sensitivity, pains to depict the effects, stability, restore the comparative analysis of effects, colors, color gamut of the richness. Songhua stone found in tests of the grainy and the ink has a strong absorption edge, has great effect of the overall picture. Therefore, the picture is more suitable for rugged performance effects of creative works. Songhua stone itself most expressive techniques of direct painting techniques course ought to pitch. Its screen rendering of water and oil ring halo effect is very rich. Texture effect more attractive, great screen tension. Therefore, the Songhua stone lithography techniques and effectiveness of their multi-faceted attempt to be more subject to future research and enrichment. For the Songhua stone lithography printmaking, brings a wealth of creative possibilities.Stone lithography research Songhua confirmed:Songhua stone with a texture of pure, absorbent compression performance, and has a certain thickness. Therefore, lithography on Songhua stone for the development of arts and culture heritage and innovation, bringing possible. Addition Songhua stone lithography can scientific development, mining will drive the Songhua stone for scientific research, social values, economic value, and makes the Songhua stone of this cultural treasure of splendor.
