KIWO EXPOCHECK EXPOSURE CALCULATOR
The KIWO ExpoCheck exposure test film uses 9 neutral density filters + 1 clear area. These areas vary in density (or degree of darkness). When exposed to a screen, each filter/density area produces 10 varying degrees of exposure on the screen. These side-by-side exposures can be judged to help determine the exposure time needed to achieve the stencil’s highest potential resistance.
