Capillary film is adhered to screens still wet from the degreasing rinse. (This rinse virtually eliminates dirt and dust that so often cause pinholes with direct emulsions, which must be coated on dry mesh). The film is attracted up into the structure of the wet mesh by capillary action. With a single squeegee stroke skim off excess water which will speed drying. After drying, the dust-protecting polyester backing is removed and the screen is ready for exposure and washout.
