A kind of printing process of described two-dimensional code anti-counterfeiting label, this method comprises the following steps：
1. the pearly-lustre microballon of different colours is prepared, the particle diameter of pearly-lustre microballon is 0.1-3 millimeters,
2. step 1. obtained pearly-lustre microballon is added in using resin as the ink of main component, obtains being used to print after mixing
The ink special of brush two-dimensional code anti-counterfeiting label, the usage amount of pearly-lustre microballon is the 5-80% of weight resin, and pearly-lustre microballon selects three kinds
Above color,
3. pattern in 2 D code is printed using above-mentioned ink special on the product or label paper for need to print Quick Response Code, makes two dimension
No more than 1 pearly-lustre microballon of printing in each cell of code, the pearly-lustre microballon of more than three kinds colors is randomly formed specific two
Tie up code pattern.
Preferably, described printing uses silk-screen printing, the size of pearly-lustre microballon close to silk-screen printing net hole size,
Each net hole is set to stamp a pearly-lustre microballon.
The present invention is made up of 2 parts：1）The synthesis of special three-dimensional pearlescent pigment, and 2）The production and printing of ink and
Record.
The present invention produces not reproducible high uniqueness 2 using method for printing and the spherical color pigment of special 3-dimensional and ties up colored mess code,
The mess code can be tested as antifalsification label by having the mobile phone of camera function and corresponding software and internet to be used for linking up with businessman
