What causes vinyl to bubble when applied to polycarbonate? How do I prevent this from happening?

Polycarbonate outgases for a period of time after manufacuring, which can cause bubbles in your vinyl. To prevent this, remove the protecting film as soon as possible and allow the polycarbonate to outgas naturally for at least 24 hours before applying the vinyl (longer if possible). Where practical polycarbonate should be baked 4-24 hours at 250° in an air-circulating oven before applying pressure sensitive vinyls. In some applications, flaming can be used. In all cases, however, see your manufacturer’s recommendations and guidelines.
