In 2016 Duffin received a RSA Gillies Bequest Award to finance an artist’s residency at the Jerusalem Print Workshop. His 2020 exhibition Peace Starts with a Smile comprised etching, mezzotint, digital printmaking collage, oils and an audio visual work, was largely the result of that residency.
Duffin is now based between his home studio in the North East of Scotland, Glasgow Print Studio (as the etching master) and the Jerusalem Print Workshop.
