Counterfeit coins have their own unique characteristics due to different means of imitation. Now they are described according to their different imitation methods:
(1) Hand-painted fake banknotes
This is copied and imitated according to the real currency. The quality is generally poor, but in the past it was a common counterfeit currency. It is characterized by the use of ordinary offset paper or writing paper, the color is the general paint or advertising color, it seems that the thickness of the pen is uneven, and the color and pattern are quite different from the real currency. Such counterfeit banknotes are easier to identify, but the elderly and children are more easily deceived.
(2) Counterfeit banknotes
This is a counterfeit note that was hand-engraved on a stenciled mimeograph. The manufacturing method is generally to engrave the wax plate of the pattern on the wax paper according to the real currency, and then print it on the paper with black and white ink, and then color the pattern. Others use color inks to print on wax plates. Its characteristics are due to the light and heavy techniques used in engraving the wax plate, which makes the wax plate leak ink slightly different. As a result, the color is different in shades, very uncoordinated, and oil immersion is prone to occur where there is too much ink leak. Because wax paper is relatively soft, it is easy to deform the pattern during printing. Therefore, such counterfeit banknotes are easier to identify.
(3) Counterfeit lithograph
This is a counterfeit note printed with a lithograph and a lithograph. Its production method is generally to engrave the plate by hand or by machine, and then print it on the small machine. Although the quality of this type of counterfeit banknotes is better than the two types of counterfeit banknotes mentioned above, the printing effect is still relatively poor. Because the lithography is hard, ink overflow or oil immersion is easy to occur. Moreover, due to the uneven surface of the printing plate, the printed patterns are different in depth, and the picture is not coordinated. Due to the inaccurate engraving of printing plates, it is also impossible to register colors very accurately, thus causing problems such as overlap, misalignment, and white leaks, and it is easier to identify them.
(4) Hand-engraved letterpress fake banknotes
This is a fake banknote printed on a wooden plate. The manufacturing method of this kind of counterfeit banknote is to use wooden board as the base material, and adopt the manual engraving method to make a relief printing plate, which is printed on a small machine. It is also characterized by poor quality. Due to the natural wood texture of the wooden board, the ink consumption is different between the texture and the non-texture, so the printed patterns are often dark and light, the color is not accurate, there are overlapping, misalignment, etc., and it is easier to identify.
(5) Extension printing fake banknotes
This is a counterfeit note printed with genuine currency. Its manufacturing method is based on real currency, using some kind of chemical to make the pattern ink on the real currency get rid of a part of it and print it on another paper to form a fake banknote. This kind of counterfeit banknote is also called Tuoyin currency. Its patterns and patterns are exactly the same as real currency. It is impeccable, but because it only gets a part of the ink on the real currency, the ink color is lighter, and the picture form is thin and beautiful. A feeling of brittle film. The real coin also suffered some damage after being printed, and some of the colors became lighter or the patterns were blurred, which is also called the coin being printed. Although the coin to be printed is formed from real coins, it must have counterfeit coins behind it, so it is more noteworthy.
