The stencil should wash off completely if the lights are safe. Then remove one coin per hour and after eight hours wash out the screen. Top Tip: An easy way to check to see if your safe lights really are safe, is to place eight coins in a line on a dry coated screen left out on a work top. The working environment in the stencil making area should be yellow safelight and air conditioned to 18вЂ“22вЊ and 50вЂ“55% relative humidity.

If the dryer can be loaded from the stencil making room and unloaded from outside this will minimise movement in and out of the room. Processed screens should be positioned in a vertical screen dryer ready for re-touching prior to printing.

Screens simply wonвЂ™t dry enough in a hot, humid box! Do not leave dried screens in the dryer for longer than necessary remove to a sealed storage cabinet when dry.Дrying and retouching.
