The invention provides a local diffusion-sawtooth anti-fake print. The print is provided with a diffusion area, an indiffusion area, a diffusion coating or an indiffusion coating. A fixed image-text ink layer edge rapidly diffuses so as to form an obvious random sawtooth under an effect of a diffusion area surface tension. A height of the sawtooth is greater than a height of a sawtooth on a two-dimensional code ink layer edge. A sawtooth density is greater than a sawtooth density of the two-dimensional code ink layer edge. The print is easy to carry out quality control, a defective index can be reduced, and a lot of a lot of printing wastes and economic losses can be avoided.
