Auto screen-printing comprises printing a layer of transparent hardening agent on a roll of polyethylene terephthalate (PET) material, printing four different color mixtures of ink and hardening agent onto the dried transparent hardening agent, printing a layer of backing ink on the color mixtures of ink and hardening and setting the printed roll of PET material in an injection-molding machine. Auto screen-printing comprises: (1) printing a layer of transparent hardening agent onto a roll of PET material by an auto screen printing press and then drying the printing; (2) printing four different color mixtures of ink and hardening agent one after another on the dried transparent hardening agent by an auto screen printing press and drying the four color mixtures respectively after each color printing; (3) printing a layer of backing ink on the color mixtures of ink and hardening by an auto screen printing press and then drying the layer of backing ink; and (4) setting the printed roll of PET material thus obtained in an injection-molding machine for injection-molding with a plastic material into the desired finish product. |
