4) Expose again for the same amount of time from Line #1
5) Slide the cardstock up, one row at a time, so that it now COVERS Rows 1 & 2, expose again for same time.
6) Slide Cardstock up, Covering, 1,2 &3, and expose again, repeat until Row 10 is exposed.
7) Washout image area with water and Select the row with the clearest detail across all sections.
8) Multiply the Row Number with Best Detail by the time from LINE #1 and that is Your Ideal Exposure time. (ie Row 6 was Best, Time Line #1 x 6= Exposure time.)
We recommend that you, do this for your different mesh counts, so that you have an exposure table with different times for varying white and yellow mesh counts.
