Tape density film in register over detailed image film on bottom of screen.
Expose twice normal exposure time, see technical data sheets for your emulsion of choice.
Increase recommended exposure times if your lamp is less than 5kw. 3x recommended time for 1.5kw lamps. 4x recommended times for fluorescent tube exposure systems. You may need to increase or decrease time to get good test exposure. If entire image on squeegee side has uncured emulsion add more time. If you can't develop image decrease time.
Evaluation:
Select the panel with the best exposure. Squeegee side of best panel should have no slime or unexposed emulsion and has good tonal reproduction from 5% to 95%.
Use the number at the bottom of the best panel and multiply this number times the exposure time.
Example: Recommended time 150 seconds. Doubled for test exposure equals 300 seconds. If the best exposed panel has a multiplier of 0.6X times 300 seconds then the correct exposure for the mesh, coating method tested is 180 seconds. Always convert this time back to units to measure light units not time. This ensures your screen receives the right quantity of light, not time, since bulbs can get weaker after repeated exposures the units setting shoots screens with better consistent exposure.
