Either ink technology will work with window perf from Continental Graphix (
www.cgxusa.com). Most window perf has 1–2-year outdoor weatherability and either ink technology will work for this length of time outdoors without lamination (Continental's PanoRama One), which I wouldn't necessarily recommend anyway. Installing laminated window perf is a rough job because it needs to be wet applied, which traps water behind the graphic. The water tends to never really evaporate, causing future problems for that particular graphic. If you need the graphic to last longer than 1-2 years there are available options that will last 3 - 5-years, at which point you'll need to consider a laminate because the inks won't last that long unlaminated...just be aware that all the water needs to be removed from behind the graphic upon installation for long term success and acceptable appearance.
