Abstract
Abstract A COLOUR PRINTING PROCESS WHICH ENABLES CONVENTINAL LITHOGRAPHIC AND LETTERPRESS INKS AND TECHNIQUES TO BE EMPLOYED FOR PRINTING ON CLASSES OF FLEXIBLE THERMOPLASTIC SHEET MATERIAL, TO WHICH SUCH INKS, BEING POLYMERISABLE, DO NOT NORMALLY ADHERE READILY, SO AS TO PROVIDE A DURABLE PRINT. THE PROBLEM OF OBTAINING AN ENDURING BOND BETWEEN SUCH INKS AND BASE SHEET, IS OVERCOME BY THE USE OF A SYNTHETIC LACQUER WHICH PERMEATES THE PRINTWORK AND SERVES BOTH AS A BONDING AGENT AND AS A PROTECTIVE COATING. THE RESULTING COLOUR PRINTS ARE MORE DELICATEA THAN THOSE PRODUCED BY THE SILK SCREEN PROCESS WHICH HAS HITHERTO NORMALLY BEEN USED FOR SUCH BASE MATERIALS.
