Dyed polyester fabrics may be printed with a plastisol printing composition substantially without dissolving the dye in the polyester fabric by initially applying a blocking composition to the fabric to form a printing receptor barrier, after curing of the blocking composition, imprinting the plastisol in a desired image or pattern onto the barrier and finally curing the print. The barrier substantially separates the fabric and the plastisol from one another to prevent chemical interaction between the printing composition and the dye in the polyester fabric, thereby to prevent undesired discoloration of the printing composition.
