A sheet of elastomeric material (12) that serves as a shock absorber and cushion for use between a flexographic printing plate (30) and a printing cylinder (14) during printing for compensating for variations in thickness, height and centricity of the printing cylinder (14) and flexographic printing plate (30) to prevent distortions in the image being printed that includes providing an elastomeric sheet having a longitudinal direction in the direction of circumferential travel of the cylinder circumference that includes a plurality or array of protrusions (20) formed of the elastomeric material (12) of predetermined cross-sectional shape and area and the material having a durometer to cushion the flexographic plate (30) in such a way to provide the necessary compensation to ensure a high quality printed image at high speed. The cross-sectional shapes and the array of the longitudinal protrusions (20) provide for material displacement zones that allows the elastomeric material (12) to be compressed and return relatively instantaneously to its original height or near original height in sharing high quality printing compensating for tolerance errors between the drum size and the flexographic plate thicknesses.
