(2) writing a special anti-counterfeiting code segmentation program, fusing a special anti-counterfeiting code picture and printed image-text contents by using VB or NET language to ensure that the appearance of the anti-counterfeiting label is not influenced by the special anti-counterfeiting code;
(3) sending the debugged template to a printing machine by using pre-printing emission software to wait for printing;
(4) selecting coated paper as a base material, and coating a layer of PE on the reverse side of the coated paper to form a PE layer;
(5) coating a coating liquid on the PE surface by using a coating machine and drying to obtain an isolation layer;
(6) printing on the coating surface by using a printer to form a first printing layer, wherein the printed anti-counterfeiting information consists of printing pictures and texts and special anti-counterfeiting codes converted into a picture form;
(7) printing water-based white ink on the first printing layer by using a gravure press to obtain a white ink layer;
(8) printing the front surface of the coated paper by using a printing machine to form a second printing layer, wherein the printed anti-counterfeiting information consists of prompt characters and anti-counterfeiting characteristics;
(9) coating the silicon oil surface of the silicon oil paper by using a spreading machine in a blade coating mode, volatilizing a solvent in the adhesive completely, and compounding the solvent and the white ink layer of the semi-finished product together;
(10) and cutting the paper into single paper surface uncovering type special code anti-counterfeiting labels by using an automatic die cutting machine.
6. The method for preparing a paper-surface-uncovered special code anti-counterfeit label according to claim 5, wherein the method is characterized in thatIn the following steps: the specification of the coated paper is 60g/m2-120 g/m2(ii) a The thickness of the PE layer is 15-20 μm; the thickness of the isolation layer is 8-10 μm.
7. The method for preparing the paper surface uncovering special code anti-counterfeit label according to claim 5, which is characterized in that: the step (5) of coating the coating liquid on the PE surface by using a coater and drying specifically comprises the following steps: coating an environment-friendly coating liquid U5000, drying by using an infrared drying mode, coating an environment-friendly coating liquid 1581 on the coating liquid, and drying by using an ultraviolet drying mode, wherein the vehicle speed is 50-70 m/min.
8. The method for preparing a paper surface uncovering special code anti-counterfeit label according to claim 7, which is characterized in that: the environmental-friendly coating liquid U5000 was prepared by mixing the following components in percentage by weight: u5000 ═ 3:1, and then coating, wherein the mesh number of the plate roller is 400-600 meshes during coating; the mesh number of the roller is 90-120 mesh when the environment-friendly coating liquid 1581 is coated.
9. The method for preparing the paper surface uncovering special code anti-counterfeit label according to claim 5, which is characterized in that: the drying tunnel of the glue spreader in the step (9) is 5 groups, the temperature of each group is 65-75 ℃, 80-90 ℃, 95-105 ℃, 110-120 ℃, 80-90 ℃ and the speed of the glue spreader is 40-50 m/min.
10. The method for preparing the paper surface uncovering special code anti-counterfeit label according to claim 5, which is characterized in that: the glue coating amount on the silicon-coated surface of the silicone oil paper in the step (9) is 10-25g/m2(ii) a The adhesive used in gluing is one of hot melt pressure sensitive adhesive, solvent adhesive or water adhesive.
