a safer studio

After becoming incorporated in 1997, the Warringah Printmakers Studio started working towards turning the workshop into a safer space by using alternative techniques to traditional etchants and solvents. The teachers at that time were very supportive of the initiative and kept a diary of observations about the newer techniques & materials. Knowledge acquired was shared and problem solving became part of the printmaking routine.
The Warringah Printmakers Studio acknowledges & thanks all of the printmakers who helped in our development as a safer printmaking studio.



Ad Stijnman, a printmaker & print historian from the Netherlands, has studied the dangers of traditional printmaking, researched less toxic procedures & given good counsel to the Studio. The following links are to essays written by Ad which are testament of his research in this area.


Workshops by visiting printmakers have been particularly helpful in showing the way towards a safer printmaking studio:-

  • Keith Howard, formerly Head of the Canadian School for Non-Toxic Printmaking at Grande Prairie Regional College, Alberta, introduced ImagOn, a photopolymer film. He also demonstrated the use of ferric chloride to etch copper plate; acrylic resist to replace the usual asphaltum-based hard & soft grounds; & vegetable oil for the cleanup of oil-based printing inks.
  • Dan Welden in 1999, Master Printmaker from New York, first developed the solarplate printing technique in 1972demonstrated the flexibility of solarplate as a printmaking medium.

Three South Australian artists gave workshops at the Studio in the late 1990s.

  • Pauline Muir, a biologist, teacher, printmaker & writer, co-authored the book Printmaking in the Sun Dan Welden in 2001.
  • Janet Ayliffe, a painter and printmaker was a pioneer of solar plate (photopolymer) plate techniques.
  • Dianne Longley, a visual artist working with a range of traditional & digital processes.
