A special group of stop light materials is for printing roll-ups and for presentation pop-up walls.
They are made of PVC, polypropylen or polyester. Their common feature is grey or silver back side that prevents from shining through. Thanks to that when the graphics is positioned even against window or against a light - the light from back does not come through and does not make the graphic visibility worse. If the print is in addition protected by antireflex lamination you could not do more for the best graphic presentation.
Stop light materials are offered cca 300μm thick for pop-up walls and cca 150μm for roll-ups.
