How do I determine if my screen is underexposed?

Touch the inside of the screen during washout. If the stencil is slimy or you get color on your finger, it is a sure bet that the screen is underexposed. To eliminate this problem, use an exposure calculator to determine the proper exposure for your screens and avoid underexposure. You can also run exposure tests to determine the limitations of your equipment and supplies.
