Dunhuang fresco color card and making method thereof

Abstract

The invention discloses a Dunhuang fresco color card and a making method thereof.The Dunhuang fresco color card comprises a carrier and a mineral pigment color block, the carrier is composed of a seal surface layer, a netted frame layer, a base plate layer and a seal bottom layer from top to bottom, the mineral pigment color block comprises a substrate and a mineral pigment coating which is applied to the substrate, an industrial paperboard obtained after a film covered layer is removed is adopted as the substrate to simulate a Dunhuang fresco base layer, the color block is coated and made through a basic Dunhuang fresco creation method, Dunhuang fresco color card category identification is printed in the middle of the lower end of a seal surface of the carrier, and corresponding position color block information and use precautions of the color card are printed right in the middle of the seal bottom of the carrier from top to bottom.The Dunhuang fresco color card is applied to Dunhuang fresco copying, virtual restoration and digitalized protection work serves as the colorimetric reference when Dunhuang fresco is copied and virtually restored, guides color correction in the Dunhuang fresco digitized process and can be adapted to diversified requirements of Dunhuang fresco protection.

Description

technical field [0001] The invention belongs to the technical field of historical and cultural heritage protection, and in particular relates to a Dunhuang mural color card and a manufacturing method thereof. Background technique [0002] Color cards are commonly used in printing and dyeing, photography, textile and decoration industries, but it is still blank in the field of historical and cultural heritage protection, especially in the field of protection of ancient murals made of rich mineral pigments. The method of making color cards assists the high-fidelity copying, virtual restoration or digital collection of ancient murals. [0003] As far as ancient murals are concerned, the content of their exquisite paintings is rich in colors and bright and bright, mainly because ancient murals are made of mineral pigments. The physical and chemical properties of mineral pigments are very stable except for lead pigments. After thousands of years, they are still It can maintain h...

Problems solved by technology

However, in the actual process of carrying out these protection work, there are the following problems: (1) The on-site copying of Dunhuang murals mainly relies on the experience of the copying workers, and each copying worker has different personal styles, which cannot guarantee the accuracy of the copying work. Consistency and faithfulness to the reproduction of the original "appearance" of murals; (2) The digital collection process of Dunhuang murals is affected by the collection equipment, the lighting source at the time of collection, and the position of the equipment and light source. The digital image draft of Dunhuang murals collected is false color, Untrue, different devices collect different color information of the same mural in different lighting environments; (3) Copy workers usually copy the mural image manuscripts collected in advance, combined with the actual color of the mural, and there are also color information. At the same time, the virtual restoration work based on the digital image draft of Dunhuang murals also has the problem of inaccurate colors

[0005] Analyzing the deficiencies of the above protection methods, the fundamental flaw lies in the lack of objective and true Dunhuang mural pigment colors as a reference, and cultural relic protection experts and scholars have not yet proposed the method of making Dunhuang mural color cards from real mineral pigments to control the protection of Dunhuang murals Accuracy and fidelity of mural colors in process
