    摘要: A simple and convenient apparatus and method for producing stamps using a photo polymer. A sandwich is constructed which includes a first ridged UV clear panel, a translucent sheet having a negative image, a first cover sheet, a pair of spacers framing the image, a quantity of liquid photo polymer filling the area over the image and between the spacers, a substrate film over the photo polymer filling, a second cover sheet, and a second ridged UV clear panel. The sandwich is held together by clamps and is placed over a raised UV window in a UV window box to selectively harden the photo polymer. Following initial hardening, excess photo polymer is washed away, the hardened photo polymer is immersed in an exposure mixture and placed over the UV window for final hardening. The raised UV window allows easy assembly of the sandwich and clearance for the clamps.
