Detailed Description
The two-dimensional code printing method of the transparent plastic film disclosed by the invention is as shown in figures 1-3, and comprises the following steps if a table printing mode is adopted:
A. the method comprises the steps that a two-dimensional code area 1 is arranged on a transparent plastic film, the two-dimensional code area 1 is usually designed to be a square area slightly larger than a two-dimensional code 2, a white ink layer 4 is printed in the two-dimensional code area 1 corresponding to the outer surface of the transparent plastic film 3, the white ink layer 4 covers the whole square area, through experimental verification, the opacity of the white ink layer 4 is larger than or equal to 45%, and under the most severe condition (namely only one layer of white ink protection is arranged above the two-dimensional code 2, namely, under the condition of the worst covering power, an interference pattern is printed above the white ink at the position corresponding to the two-dimensional code 2), the promotion information cannot be identified by scanning the promotion two-dimensional code 2 on the front side, but the promotion information can be accurately identified by scanning the promotion two-dimensional code 2 on the back side of a package;
B. printing a color ink layer 5 on the white ink layer 4, wherein the color ink layer 5 is formed by interference patterns which are arranged discontinuously, the color of the color ink layer 5 adopts the dark color in the existing color designed on the transparent plastic film 3, such as black, blue and the like, so that not only can the addition of new printing colors be avoided to save the cost, but also the interference effect on the scanning of the two-dimensional code 2 on the back surface is facilitated, the interference patterns can adopt patterns which mainly adopt small-area discontinuous type and accord with brand image and beauty, such as continuous repeated brand LOGO and the like, and generally do not exceed the area range of the white ink layer 4, and the scanning of the two-dimensional code 2 can be interfered (as shown in figure 1) by the superposition of the interference patterns and the two-dimensional code 2, so that the field or flat screen covering of common color ink is avoided;
C. and spraying the two-dimensional code 2 in the two-dimensional code area 1 corresponding to the inner surface of the transparent plastic film 3.
