Abstract

A screen-printing panel comprising a locking strip sewn to screen-printing mesh is described. The mesh along an edge of the panel is folded around the locking strip and secured using a line of stitching. A gap between the end of the locking strip and the edge of the mesh contributes to corner softening. Another gap between the end of the stitching and the end of the locking strip also contributes to corner softening. Locking strips have various cross sections including rectangular, triangular, and complex curves. Two colors of thread may be used to aid in orienting the panel. An adhesive may be used to hold the mesh to the locking strip for convenience during handling and sewing.
