AbstractA method and kit for transferring creative free-hand artwork or patterns onto a T-shirt or similar fabric is described. The transferable pattern is created from a manifold of a heat transfer sheet and a reverse or lift-type copy sheet having a pressure transferable coating of heat transferable material thereon. By generating the pattern or artwork on the obverse face of the transfer sheet with the pressure of a drafting implement a heat transferable mirror image pattern is created on the rear surface of the transfer sheet by pressure transfer from the copy sheet, which can then be applied to a T-shirt or other article by heat transfer. To provide interesting background colors and patterns on the T-shirt on which the free-hand artwork is superimposed the rear surface of the transfer sheet may be coated with a negative image of the background pattern formed from heat transferable inks. The transfer sheet may be transparent so the negative background image on the rear of the transfer sheet is visible as a positive image through the obverse surface.In the alternative the background image, or at least an outline thereof, may be printed on the obverse surface of the transfer sheet as a guide or framework in which the free-hand artwork is performed. The free-hand artwork and background pattern are then transferable together from the rear surface of the transfer sheet to the T-shirt or similar fabric. | InventorApplicationNo. 06/087767 filed on 10/24/1979US Classes:156/234, Of portion only of lamina from carrier101/470, Utilizing radiant energy or heat156/235, Plural transferring operations and/or with additional laminating156/240, Transfer of printing or design427/148, Heat sensitive428/914TRANSFER OR DECALCOMANIAField of Search156/234, Of portion only of lamina from carrier156/236, Solvent other than water to release lamina156/240, Transfer of printing or design156/299, All laminae planar and face to face156/230, Direct contact transfer of adhered lamina from carrier to base156/246On temporary planar support (e.g., film casting)ExaminersPrimary: Weston, CalebAssistant: Falasco, Louis Attorney, Agent or FirmUS Patent References3095649, 3578525, 4075049, Method of preparing retroreflective sheetingIssued on: 02/21/1978 Inventor: Wood4089722, Method of affixing heat transferrable indicia to a fabric surface Issued on: 05/16/1978 Inventor: Holoubek4145244Portable transfer toy Issued on: 03/20/1979 Inventor: Covey International ClassesB44C 1/17 (20060101)D06Q 1/12 (20060101) D06Q 1/00 (20060101) |
