Puretch photopolymer high resolution etching resist for fine art photo etching and photo circuit boards, PCB. This DIY video will show you how to expose a plate with Puretch photopolymer without the need of a professional UV vacuum contact frame exposing unit. A clear mylar Space Bag® and 500 watt halogen spot light will be used instead. Exposure is for 5.5 minutes, 18" from bulb. Note: a professional UV exposing unit and vacuum frame is recommended for very fine halftone work as there is a slight loss of details in the highlights with the space bag. The space bag is ideal for coarser bitmaps, line work or circuit designs. Use all materials at your own risk. capefearpress.com ©2009
