POWDERING
The film then passes through a chamber where powder adhesive is applied to the semi-cured ink. A pulse mechanism shakes off and collects any excess powder, which is then reused to ensure zero waste. The powder sticks only to the ink, not the film, which then proceeds through a heating process to cure the powder into the ink. Depending upon the amount of ink used, the heat applied can be anywhere between 85-120C. The heat transforms the powder into a liquid which binds to the ink in a very thin, transparent layer.
