2.11 GRAPHICS

A. Xtreme Graphic Logo The Xtreme Graphic Logo is comprised of decorative artwork and/or text that has been permanently bonded to the front vertical surface of the bleacher seat modules. The artwork is tiled, a process whereby a single large graphic is segmented and applied in separate parts to individual seat modules, which, when viewed together as a whole become a unified piece of artwork, similar to a mosaic.

The graphics are printed as full color CMYK pigmented resin and adhesive layer onto a 100UM polyester clear glossy release film (transfer sheet). The application process uses a combination of heat and pressure to activate the adhesive and permanently bond the resin to the HDPE seat module. Once applied, the graphic cannot be removed from the seat module without damaging or destroying the seat module surface.

Customer must provide vector-based digital artwork, and approved layout indicating tiled application to individual seat modules to be provided with bid.

B. Factory or Dealer designed logo that incorporates school letters or graphical representation of school logo across the front of the bleachers.
