1. Observe the front trademark printing: the trademark paper of genuine cigarettes is printed by offset printing, the font of "Golden Leaf" is embossed and bronzed, the font strokes are full, clear and thicker, the fake cigarettes are printed by high-definition scanning imitation, the font strokes are thinner and the edges are rough, and the words "Golden Leaf" of real cigarettes feel concave and convex due to the printing process.
2. Check the printing of the label paper on the back: the vein of the middle leaf of the real cigarette is clear and stereoscopic, and the leaf color is dark; The veins in the middle leaves of fake cigarettes are blurred and have no three-dimensional effect, and the leaves are lighter in color.
