Preferentially painted textured slats for vertical and horizontal blinds
摘要:
Extruded material for forming blind slats has at least one textured surface with raised areas and adjacent lower areas. After extrusion and texturing processes, the slat material is passed through a spray painting process applying a substantially thicker coating of paint to the raised areas than to the adjacent lower areas.
