Removing template sediments from screen printing template support - involves directing liq. jet at impingement pressure, sufficient for mechanical removal, onto template support

摘要

The sediment removing liq. jet (49) is directed onto the template support (23) at an impingement pressure sufficient for the mechanical sediment removal. The sediment is removed by a relative movement between the liq. jet and the template support. Pref. the template support is fixed, and the liq. jet is moved w.r.t. it. If a rotary screen printing forme is used, the template support is rotated, while the liq. jet is linearly moved parallel the template support longitudinal axis. USE/ADVANTAGE - Cleaning of rotary printing formes, using water soluble photofilms, without use of dangerous solvents.
