Offset printing on curved surfaces
Abstract
Abstract A PRINT IS MADE OF AN OBJECT HAVING A SURFACE WITH A CONSIDERABLE CONTOUR VARIATION BY FIRST PRINTING THE IMAGE ON AN INTERMEDIATE CARRIER SURFACE WHICH IS CAPABLE OF BEING DEFORMED IN SUCH A MANNER THAT IT WILL ENVELOP THE REQUIRED AREA OF THE SURFACE UPON WHICH PRINTING IS TO BE DONE WITHOUT WRINKLING AND WITHOUT ALLOWING RELATIVE MOVEMENT OR SLIDING BETWEEN THE OBJECT SURFACE AND TRANSFER SURFACE AS THEY ARE BROGHT INTO CONFORMING CONTACT AND THEN SEPARATED. THE IMAGE MAY BE TRANSFERRED FROM THE INTERMEDIATE CARRIER SURFACE EITHER BY THE APPLICATION OF AN ELECTRIC FIELD WHILE THE INTERMEDIATE CARRIER AND THE OBJECT ARE IN CONTACT, OR BY APPLYING A THIN LAYER OF A SUITABLE LIQUID TO THE OBJECT SURFACE PRIOR TO APPLYING THE INTERMEDIATE CARRIER THERETO.
