Manufacture of a plastic card involves providing a sheet of lenticular lens material, coating a back side of the material with a vinyl resin base, printing the back side of the material with a composite lithographic image, coating the back side of the material with an adhesive to serve as the back of the plastic card, and laminating the sheets together. Manufacture of a plastic card involves: (a) providing a lenticular lens material having front and back sides, with an array of identical spherically curved surfaces embossed on the front side and flat on the back side; (b) coating the back side of the lens material with a vinyl resin base; (c) printing the back side of the lens material with a filmed image; (d) coating the back side of the lens material with an adhesive such that it can adhere to a sheet of plastic which serves as a back side of the plastic card; (e) providing a sheet of plastic having a front and a rear surface; (f) printing the rear surface of the plastic sheet; (g) providing a sheet of clear polyvinyl chloride (PVC) overlay film; (h) laminating magnetic material onto the sheet of overlay film; (i) assembling and collating the lens material, sheet of plastic and sheet of overlay material with laminated magnetic material such that the sheet of lens material is oriented on the top of the three sheets and the plastic sheet is oriented in the middle of the three sheets, and (j) laminating the three sheets with the magnetic material at approximately 290[deg]F and a pressure of 200 psi for approximately 25-30 minutes. An independent claim is also included for a plastic card prepared by the above method. |
