Description
The author is describing how to use a System 3 Removable Screen Block to block out a drawing surface so that subsequent drawings can be washed away with cold water. The screens can then be reclaimed and used again.
Once the drawing fluid is dry, the entire screen surface is then
blocked out with System 3 Removable Screen Block, applied by squeegee.
Again, once dry, the previously drawn image is washed out in cold water
to leave an open-mesh positive image ready for printing. The screens
can be reclaimed after printing by washing out the screen block with
hot water and soap. Screen Block should be kept upright and stored at
normal room temperature.
