S I G N & D I G I T A L G R A P H I C S • November 2018 • 57 is already being reduced slightly before you started application," says Place. "So if some variation would cause gloss band- ing, it is not going to be quite as pro- nounced with the luster." 3M has two versions of its 480mC film, one for solvent-based print appli- cations and one for latex. Both work with UV printing. To apply rough surface wraps, a shop will need a heat gun capable of achieving 1,000 degrees Fahrenheit. "That may not be the actual tempera- ture at the film surface during applica- tion, but the gun itself needs to reach 1,000 degrees Fahrenheit as the recom- mended temperature for the application," he says. 3 M also offers a textured surface applicator tool that attaches to the heat gun. It is two handed which makes it more comfortable to use for the installer. "It is a more ergonomic solution to applying rough application films," Place says. 3 Ms 480 film is "very dimensionally stable," he adds. That means it has a ten- dency to retain its shape without elonga- tion in a broader range of temperatures. 3M technical specialists train installers to lock down the graphic on three sides to prevent any vertical shrinkage and by locking down one vertical side, it can minimize or eliminate horizontal shrink- age that might occur as well, he says. 3 M also has a retroreflective grade wrap film called Scotchlite 780mC-10R that was developed to handle contours and flat applications. Initially it was used for highway or roadway signage, includ- ing lane separators. "Lately, there's been an increase in the amount of reflective films used on vehicles for safety. Many surfaces, the irregular surfaces customers are trying to apply these non-conforming reflective films to, are exceeding the capabilities of the film which creates defects and blem- ishes from repositioning and handling it," Place says. The 780m C can be installed over contours and it was developed for easier repositioning and removal. "We want to take the vehicle safety aspect of reflective to a whole other level by allowing a vehicle to be wrapped entirely in reflective materials. Up until the 780m C, it was virtually impossible," he says. So even though the 780mC wasn't developed specifically for rough wall applications, it is performing well in those applications so "what this does is it creates an opportunity for potential rough wall applications with the added benefit of higher visibility." One application for this technology would be parking garages where the own- ers are trying to get people moving in the right direction to exit the building or return a rental car. Lighting in many garages is poor. Having 780m C reflec- tive material gives the building's signage higher visibility.
