Gradual change type 3D optical texture film manufacturing method

The invention discloses a gradual change type 3D optical texture film manufacturing method. The method comprises the steps that a 3D optical texture pattern is manufactured; a colorful gradual changetexture file is manufactured; a die pressing technology is adopted for die pressing of the 3D optical texture pattern on a transparent base material, and accordingly an optical texture film is formed;the colorful gradual change texture file is adopted for plate making and printing plate output; and an output printing plate is subjected to gradual changing printing on the surface of the optical texture film, and accordingly the 3D optical texture film with the colorful gradual changing colors is obtained. The manufactured optical texture film with the 3D effect has the advantages of being resistant to abrasion and scratching, good in attaching force, high in layering sense and obvious in third dimension effect; meanwhile, the obvious nonlinear stripes, the 3D water drop effect, the 3D water wave effect, the 3D lens
