LSL 83SM 4" x 5.5" steel backed polymer plates
Steel backed photopolymer plates are 0.83 mm thick and have a luster finish after processing. They share all the good qualities of the LSL material and differ primarily in the finish and thickness of the plate. The durometer value for this plate is 80 Shore D.
These smaller plates are from a remainder cut from larger sheets. We have separated them into two batches: one batch has the protective covering intact and is suitable for making intaglio plates, and a second batch that have random bubbles in the protective covering and will work for making relief plates only.
