Drawing technique on ancient fresco holographic copying substrate material

Abstract

The invention provides a drawing technique on an ancient fresco holographic copying substrate material. The drawing technique comprises the steps that according to a syntax and a picture in image information of an ancient fresco to be copied, double drawing of a contour line is carried out on a graph in the picture on the ancient fresco holographic copying substrate material, then color filling is carried out on an internal area of the double-drawing line, and drawing of a solid color area in the ancient mural image to be copied is completed; engraving and copying are carried out, specifically, according to the imprinting trace condition in the image information of the ancient mural to be copied, shallow engraving is carried out in the drawn solid color area, the shallow engraving area is filled with a diluted Chenban soil aqueous solution to complete copying of the imprinting trace; and printing and copying are carried out, specifically, according to the surface print condition in the image information of the ancient mural to be copied, the surface print contour in the drawn solid color area is drawn by using a blended glue solution or a blended glue solution composition, the surface print contour is filled and brushed with alum water, then the color area is covered by using a light mineral pigment, then dotting is carried out, and copying of the surface print is completed.

Description

technical field [0001] The invention relates to a drawing technique performed on a base material for holographic copying of ancient murals, and belongs to the technical field of copying ancient murals. Background technique [0002] The drawing techniques and trace expression techniques in the existing ancient mural reproduction expression techniques are various in form and widely used, and most of the expression techniques are performed on specific base materials, such as paper materials or clay materials. Although the holographic copying of ancient murals can be realized on the specific base material by these expressive techniques, there are still many disadvantages, such as: the paper material cannot be scratched, and the tolerance is not enough , after multiple glue colors are superimposed, damage will occur; for mud skin materials, it is not easy to control the thickness of the marks in the scratch performance. The lines of scratches are uneven, especially for scratches...

[0002] The drawing techniques and trace expression techniques in the existing ancient mural reproduction expression techniques are various in form and widely used, and most of the expression techniques are performed on specific base materials, such as paper materials or clay materials. Although the holographic copying of ancient murals can be realized on the specific base material by these expressive techniques, there are still many disadvantages, such as: the paper material cannot be scratched, and the tolerance is not enough , after multiple glue colors are superimposed, damage will occur; for mud skin materials, it is not easy to control the thickness of the marks in the scratch performance. The lines of the marks are uneven, especially for the scratches after water spraying or the water treatment after the scratches are made, usually there will be problems of lifting and partial block falling off

[0003] For the base material of holographic copying of ancient murals, due to the particularity of material and composition, some traditional expression techniques are not suitable for holographic copying of ancient murals on the base material
