Abstract: A computer driven device for making silk screens suitable for making signs, PC boards, mask, metal, textile graphics and the like is disclosed. The device uses a laser beam to burn holes in a thin sheet of plastic, preferably nylon. The laser beam is directed toward the surface of the nylon screen and the beam is moved incrementally under computer control to position the two before activation of the laser. The desired sign or pattern to be burned into the screen is constructed by means of a microprocessor or PC using a desk top type publishing program. The finished nylon "silk" screen can be used in the same manner as conventional silk screens.
