Several methods to distinguish the true and false dollars;
1. Handfeel identification: Gravure printing is engraved on the front and back of the genuine element. Touching the four-corner denomination figures by hand has obvious concave-convex feeling, while the fake element generally does not need to be touched by hand. Observing with a magnifying glass, you can see gravure miniature characters.
2. Needle-picking identification: the blank of the real dollar face contains tiny red and blue fiber filaments, which can be picked out with the needle tip. Some counterfeit money has no red and blue fibers, some only print fiber filaments that cannot be separated from paper, and some paper has red and blue fibers. Although they can also be picked out with a needle, the pseudofilaments are made of different materials and have no fluorescence reaction when examined under purple light.
3. Wipe identification: The green emblem and numbers on the right side of the genuine yuan ticket will leave obvious green marks on the paper after being wiped hard on the white paper. Although there are traces after rubbing on fake dollars, they are not obvious.
4. Texture identification: Zhenyuan is a special paper for printing banknotes, made of cotton and linen fibers. The texture is tough and straight, and it can make a snapping sound with a flick of the hand, while the fake dollar has no sound.
5. Color identification: The figures, images, characters and lace on the front of the real element are printed with black gravure ink containing magnetic substances, which is bright and eye-catching, while the fake element is printed with inferior ink, which is very different from the real element.
6. Portrait recognition: Real dollar portraits have bright eyes, while fake dollar portraits have dim eyes and blurred lines.
