A method and associated apparatus for use in an automated sign generator to produce enhanced special effect graphics and single layer multi-color signs on a vinyl sheet material uses a paint pen carried by the tool head of the generator which in coordinated movement with the vinyl sheet traces the shape of the sign. In one embodiment, the sheet material is cut along a line falling within the painted stripe defining the graphic. The cut graphic having the desired visual special effect is removed from the sheet material along the cut line. The apparatus further includes a guide wheel assembly located between a material deflector and a feed roller for riding along the marginal portions of the sheet material causing it to move along a broken plane path to prevent buckling as it moves relative to the tool head and to prevent smudging of the painted graphic. A cam clip assembly is located behind the feed roller and intermediate the feed roller and a cam shaft and rides along the marginal portions of the sheet material to cause the material to move along a broken plane path to prevent its buckling and avoid smearing of a painted graphic on the surface. A paint pen which is interchangeable with a cutting tool is carried by the tool head and includes a number of interchangeable paint nibs.
