Method for printing common Chinese art paper by offset press

Abstract

The invention provides a method for printing common Chinese art paper by an offset press, and belongs to the technical field of Chinese art paper printing. The method comprises the following steps that (1) paper preparation, (2) printing on the offset press and (3) processing after printing. According to the (1) paper preparation, a, the Chinese art paper is unfolded and flattened, and a rough product is cut; b, offset paper is cut to be of the size matched with the size of the Chinese art paper; c, the offset paper is cushioned under the Chinese art paper; d, the cushioned offset paper and the Chinese art paper are matched to be cut to be of the printing size; e, two adhesives are brushed on the same sides of the offset paper and the Chinese art paper after cutting is completed, and bonding is conducted; f, the bonded Chinese art paper and the offset paper are subjected to paging. According to the (3) processing after printing, one side of the offset paper and one side of the Chinese art paper are cut off after the adhesives are brushed. When the method is used for printing the common Chinese art paper, paper feeding is convenient, the breathability of the Chinese art paper in the printing process is good, the Chinese art paper is naturally disengaged after printing, the production cost is low, the production efficiency is high, the method is suitable for mass production, the printing process is high in controllability, overprinting is light and accurate, the color reducibility is high, and the reproduction accuracy is high.

Description

technical field [0001] The invention relates to the technical field of rice paper printing, in particular to a method for printing common rice paper by an offset press. Background technique [0002] At present, in the technical field of rice paper printing, old-fashioned two-color printing machines are generally used for printing or professional high-gram weight rice paper that can be printed is used. The old-fashioned two-color printing machine is printed by manually feeding and removing paper. However, this method has low production efficiency, inaccurate overprinting, and high labor intensity. It is printed on professional high-gram heavy rice paper that can be printed. Although the problems of overprinting accuracy and labor intensity have been solved, the printing effect is not satisfactory, and it is difficult to reflect the realism of calligraphy and painting works. In the modern offset printing process, the printing range is 50-400g. Ordinary rice paper itself is li...

AI Technical Summary

Problems solved by technology

The old-fashioned two-color printing machine is printed by manually feeding and removing paper. However, this method has low production efficiency, inaccurate overprinting, and high labor intensity.

Printed on professional high-gram heavy rice paper, although the problems of overprinting accuracy and labor intensity have been solved, but the printing effect is not satisfactory, and it is difficult to reflect the realism of calligraphy and painting works

In the modern offset printing process, the printing range is 50-400g. Ordinary rice paper itself is light and thin, and it is less than the minimum range of 50g, so it cannot be directly printed on the machine.

Patent 201410030765.X discloses a method of printing rice paper using an offset printing machine. Although water-soluble glue is evenly applied between rice paper and cardboard, after flattening and printing, post-processing is performed to cut off useless printing bleeding Spray the surface of the rice paper with 50-99% alcohol water to make the surface of the rice paper wet and overcast. It is inconvenient to remove the rice paper after treatment, and it will seriously affect the high degree of color reproduction and high reproduction accuracy of the printed pattern on the rice paper. , destroying the beauty of rice paper printing patterns
