It's had more than 20 years championing the work of this country's print makers. Now Print Council Aotearoa New Zealand has published a book featuring a dazzling array of prints by its members. PCANZ has around 250 printmakers, and many of them are seriously pushing the boundaries with their techniques. In Proof : Two decades of printmaking each artist provides a short note describing their work - some breaking new ground, but many using traditional techniques, like screen printing, lino and wood cuts. Lynn Freeman spoke to two of the print makers who've worked on the book - Kathy Boyle and Heather Partel. Proof : Two decades of printmaking is published by Massey University Press.
