Abstract
The present invention provides a process for regenerating used screen printing frames contaminated with residues from the screen printing process comprising heating the used frame at a sufficient temperature and for sufficient time to thermally degrade the residues. The process is used particularly for removing mesh, adhesive, printing ink and/or residual paint from the frame.
