The Segue Sunrise Portable Display Kitis an indoor aluminum extrusion frame system. Dye Sublimation Graphics for the Segue Sunrise use the Silicone Edged Graphic system (SEG) of sewing silicone strips (welting) around the perimeter of the Dye Sub graphic. The graphic edge inserts into the groove on the perimeter of the frame to create a taught, flat display with a neatly finished corner. What is SEG? SEG stands for Silicone Edged Graphics. With SEG, fabric graphics are finished with a silicone welting sewn to the back perimeter edge of the fabric. Unlike round beaded finishing options SEG is a flat silicone welting. This edge is then inserted into a groove on the perimeter of the frame to create a taut, flat display.
