Benzene ring network structure for intaglio printing

Abstract

The invention discloses a novel benzene ring network structure for intaglio printing, and aims at solving the problems of poor drying, plate blocking, ripples and the like occurring when an existing printing plate is used for net printing of water-based ink. Under the condition of not influencing the printing durability, the net hole area can be increased, the net hole depth can be reduced, the ink transfer rate can be increased, and the phenomenon of ripples can be reduced. According to the benzene ring network structure for intaglio printing, net holes are hexagonal, and in every six net walls between each net hole six adjacent net holes around, three connected net walls are thick edge net walls, two net walls connected with the three thick edge net walls are thin edge net walls, and thenet wall between the two thin edge net walls is a thick edge net walls. The width of the thick edge net walls is two times that of the thin edge net walls.

Description

technical field [0001] This patent relates to the field of printing technology, in particular to a benzene ring network structure of a gravure printing plate. Background technique [0002] Water-based ink is generally considered as a promising environmentally friendly ink by virtue of its many advantages such as no volatile organic solvents, non-flammability, good environmental protection, and low price. Drying performance is one of the most important indicators of water-based inks. However, due to the high surface tension and high boiling point of water, it is difficult for the ink to wet, so its drying speed is slower than that of solvent-based inks, which may easily cause sticking or water ripples on the back. [0003] Gravure dots are composed of mesh cells and mesh walls, which are different from other printing dots such as letterpress and lithography. Letterpress and lithography use the size of the dot area to express the level of the printed matter, while gravure pri...

Problems solved by technology

[0009] In view of the shortcomings of the above-mentioned prior art, the purpose of this patent is to design a special new type of gravure printing benzene ring network structure, aiming at solving the problem of poor drying, plate blocking, water loss and other problems in water-based ink using the existing printing plate screen printing. Ripple and other problems, it can increase the cell area, reduce the cell depth, improve the transfer rate of the ink, and reduce the water ripple phenomenon without affecting the printing force
