Hello all - I know there are several of ya'll who make your own stencils. I have a couple (few?) questions. I'm using IMG stencil material and their developer. When the stencil material comes out of package it's a light blue/green and fairly transparent (I cut a small piece in dark room with low level yellow light only). After laying in direct room light for a few hours it turns a dark opaque blue. While working in dark room (low level yellow light only) I place stencil material on black rubber mat (bottom of mouse pad), lay transparent logo on top, lay glass on top of all to hold flat. Then expose to a 100 watt incandescent light bulb in reflector held 2 to 3" away from glass. I've exposed for several different time periods with differing results. After exposing to light, film covering is removed from both sides before placing in developer.
My questions,
1. Should exposure be long enough the logo image will be visible after exposure but before developing?
2. Should the stencil turn almost opaque dark blue after exposure? OR, turn dark only after developing?
Thanks for any suggestions and help,
Ken H>
