1. The printing process of the small box trademark paper is different: the genuine trademark paper uses coated paper and gravure printing. The three "ㄑ" in the strokes of the "经" font are basically the same size. The strokes of the 1956” font are uniform in thickness, strong in three-dimensionality and relatively thick.

The fake cigarettes are printed with high-definition scans and imitations. The sizes of the three "ㄑ" "ㄑㄑㄑ" in the "经" font strokes are inconsistent, the last "ㄑ" is particularly small, and the thickness of the "1956" font strokes is inconsistent. It is uniform, has no three-dimensional effect and is relatively thin. There are obvious differences between the trademark paper printing process and the characteristics of the genuine product.

2. The small box seal printing is different from the lining paper: the genuine cigarette seal is gravure printed, with thick vertical lines, obvious small dots next to the two tobacco leaves, more regular arrangement, and larger size. Uniform, the dots on the lined paper are neatly arranged and the gaps are relatively large, making it look sparse.

The vertical lines on the counterfeit cigarette seals are thin, and some of the small dots next to the two tobacco leaves are arranged irregularly and unevenly in size. The dots on the lining paper are arranged tightly in an obvious grid shape; small Box seal printing and lining paper differ significantly from authentic features.

3. The length of the cigarettes is different: the length of the filter tip of the real cigarette is 24mm; the shorter length of the filter tip of the fake cigarette is about 18mm, which is obviously different from the genuine cigarette.

4. Different shredded tobacco: the shredded tobacco of real tobacco has a moderate and uniform width and length, an orange color, good gloss and oiliness, soft and loose, the shredded tobacco contains less fines, and the structure of the shredded tobacco is shredded leaves, Tobacco leaves are reconstituted by expanding cut stems and paper making.

The process of making fake cigarettes is rough, generally using untreated low-quality shredded tobacco. The color is dull and dark brown. The shredded tobacco contains a lot of fine particles. The structure of the shredded tobacco is generally leaf shreds and has not been processed. Expanded cut stems and non-paper-making method of reconstructed tobacco leaves have obvious differences in the structure of the cut tobacco and the characteristics of the genuine product.
