ABSTRACT:
The web is a substantially flat laminate in the form of a base sheet having a permanent upper surface of plastic material defining a base color, which may optionally be clear. A final graphics layer covers the base sheet and has an upper surface colored differently from the base color and a lower surface adhering to the upper surface of the base. The peel values of the upper and lower surfaces of the layer relative to each other and to the upper surface of the base are such that the cut graphic pattern in the layer remains secured to the base while the other portions of the layer may readily be peeled from the base without excessively adhering to and thereby removing the graphic pattern from the base. Preferably, two or three differently colored layers are laminated with the base, to permit the making of a sign having two or three different colors in addition to the colored (or clear) base. An important characteristic of the colored layers is the peel values between the upper and lower surfaces of the adjacent, laminated layers in the web, and among the upper and lower surfaces of all layers during weeding of the unwanted portions of the layers after the graphic pattern has been cut.
