You don't have to sensitize it and it is much more sensitive to UV-A energy, so your exposure time is shorter. Stencils are good for about 4 weeks after you coat them when they are stored in a cool dry place away from heat and UV-A light.Ĭonsider a faster SBQ emulsion. If you underexposed, there aren't lots of links to break, and you have to use brute force to punch the stencil from the mesh, instead of the smooth breakdown of the stencil like turning a key in a door lock.
