Principal Applicant Address Taiwan Inventor Huang Ruipeng Application (patent) No. 200410049700.6 Application Date 2004.06.24 Certification Date Approval Notice No. 1712219 Auditing Notice Day 2005.12.28 Instruction CD No. D0552 Main Classification No. B41F15/00 Classification No. B41F15/00; B41M1/30 Subdivision Original Application No. Priority Abstract The color pattern screen printing method of the shell subjected to in-mold marking hot pressing, roll forming and injection molding mainly adopts the first, second and special color inks of the four-color sleeves in the screen printing method to add hardening. After the printing process of the agent and adhesive agent, the first, second and third screen printing procedures outside the graphic are performed. In addition to the general colors that can be printed, metal (silver) and pearl colors can be printed on the surface of the film material. After hot-pressing and roll-pressing molding, the film material is molded and injected together with the plastic to complete the surface color, metallic color and pearl color of the shell. Sovereignty item 1. A color pattern screen printing method capable of withstanding the IML hot pressing, rolling and forming and injection molding of shells, mainly using screen printing method, in addition to printing the general color, in particular, the metal color The pearl color is printed on the film material as a shell. This method includes: a) first screen printing first color printing, using a screen printing machine to print the first color ink on the film material, adding a hardener and a bonding agent; After the printing and curing of the ink plus curing agent and the adhesive agent are completed, the first drying process is performed; b) After the completion of a), the second step of screen printing is performed in the second color printing, using a screen printing machine, After the second color ink plus hardening agent and bonding agent are printed on the surface of the first color ink plus curing agent and the bonding agent, a second drying process is performed; c) After the completion of b), the third step is performed The last color of the screen printing is special color printing, and the special color ink plus curing agent and bonding agent are printed on the surface of the second color ink plus curing agent and the bonding agent by using a screen printer, and then the third drying process is performed; d) After the completion of c) In the fourth screen printing, the first screen printing outside the text, the ink plus hardener and bonding agent are printed on the surface of the special color hardening agent and the bonding agent, and then the fourth drying process is performed; e) d) After completion, perform the second screen printing of the fifth step outside the picture, print the ink with hardener and paste on the surface of the first screen printing outside the picture, and then perform the fifth drying process. f) After completion of e) Completion of the third screen printing outside the picture of the sixth step, printing the adhesive on the surface of the second screen printing outside the picture, and then performing the sixth drying process After the above steps (a, b, c, d, e, and f) are completed, hot pressing, roll forming, and injection molding are performed, and the finished product is finished.
