Pre-sensitized w/ uv fluorescent bulbs - 3 minutes.Pre-sensitized w/ 500watt halogen light - 8 minutes.*Not sure where to start? Try plugging in these numbers for step 1 and go from there: If you were burning in 18 second increments, the correct exposure time would be 126 seconds (18x7=126). For example, if row 4 came out the best, 11-4=7, meaning row 4 got exposed a total of 7 times during the test. Lastly, take the number of the best row and subtract from 11.Wash out the screen, allow to dry, and determine which row came out best.Continue moving the paper down and exposing until you have reached the bottom.Expose the screen for the amount of time you came up with in Step 3 again.Move the thick, opaque paper down to where it is covering all but the first 2 rows.Expose the screen for the amount of time you came up with in Step 3.Tape the calculator to screen, and cover all but the first row with thick, opaque paper.Take your new time calculated in Step 2, and divide by 10.

Take that amount of time, and multiply by 1.5 (Ex.*Guess how long it will take for your screen to burn (Ex.We understand this math can seem a bit intimidating at first, but just take your time and trust the formulas.
