Porta John Decals and Signs from Anchor Graphics are made with aggressive adhesive that adheres to both smooth and coarse surfaces such as on portable restrooms and garbage totes. They are durable and weather-resistant. They are either taken to the company’s silk screen department or a large UV printer, where an artist moves a blade across the decal, followed by a reversal of the stroke to bond the ink to the vinyl. They can be printed in one color or full color. The durable, adhesive vinyl is taken to a die-cutting kluge press where the image and/or logo is carefully carved. Several dimensions and colors are available. 972-422-4300; www.anchorgraphics.com.
