Nowadays, gravure printing is still widely used in banknotes all over the world. Gravure printing is a traditional way of printing banknotes. The inked part of this printing plate is concave. The ink in the concave pattern is directly transferred to the paper under strong pressure, and the ink shows a three-dimensional state on the paper. , So there is a feeling of unevenness when touched by hand.
The group on the paper currency is mainly made by hand-carving, and the exquisite figure of the figure is not only a high-end artwork itself, but also has the function of anti-counterfeiting. Each engraver has different styles and characteristics, which cannot be copied. At present, there are many advanced copying techniques and counterfeiting techniques in the world, and it is still impossible to copy exactly the same banknotes out of hand-carved works. Therefore, hand-carving and gravure printing are still a kind of anti-counterfeiting means used internationally.
One of the most critical aspects of printing banknotes by hand engravers is very difficult. No mistakes are allowed. The tools for hand carving are not knives or pens. The steel plate is slightly softer than ordinary steel plates. When the carver works, he must hold the magnifying glass in one hand and hold the pen in the other, and scribble the lines one by one on the steel plate. There are even a few mistakes that will give up his previous achievements. Someone counted the number of points and lines on a banknote, and a carver carved a million knives on a banknote.
The Daqing Silver Dollar Exchange Voucher printed by the Printing Bureau of the Daqingdu Branch in 1910 was the first set of engraved intaglio banknotes issued in China. The engraved part was completed by American engraver Haiqu. The saying "no coins can be made without concavities" is widely circulated in the world.
