Yes, there is. When curing PERMASET Puff Paste, ensure that the prints have been air dried or heated @ 60°C (140°F) until dry. Once the Puff print has been dried, cure for 4-5 minutes @ 145°C (295°F) for optimum print performance. As a caveat, if you overcure Puff prints, the little air-bubbles explode and collapse, leaving a very unattractive thick plasticky film.
