IMPORTANT note on printing the artwork :  Open the pdf file with Acrobat Reader. Use a laser printer to print the artwork on tracing paper *  in true size (i.e., : do not enlarge or shrink the artwork). The printed artwork can be used for direct exposure with UV sensitized pcb such as the Kinsten PP-1530.     
(* tracing paper is the type of translucent paper used by architect for drawing plans. It's much cheaper than OHP transparency)
