21 STEP SENSITIVITY GUIDE
This all purpose precision exposure guide can be used on all stencil types to determine and standardize proper exposure accurately and quickly.
Place the Saati 21-step guide on the screen. Optimize your exposure so that when washing out the image, you are left with 7 solid steps. If you see only 5 steps, you can run the risk of pinholes or premature breakdown, and you should double the exposure time. If you see 9 steps, you will have lost finer detail in the image, and you should halve the exposure time.
