Art and Stationery Supplies Design Gradient Ramp Tape by Bruce Tao Gradient Ramp is an adhesive tape designed to make the cut end easier to find. Standard transparent tape is very thin, so the edge is often hard to locate after use. Gradient Ramp carries a gradient of color along its length. When the tape is cut, the layers create a visible color difference at the cut line. The user looks for the area of strongest contrast and lifts the tape from that point. The tape is made of a PVC film without plasticizer, which offers good low temperature resistance, strong initial tack and easy cutting.
