This is a very accessible image originally introduced to workshop members by visiting artist Vinita Voogd a Californian artist. She has developed a remarkable three layer technique using process cyan, magenta and yellow inks, which when overprinted gives a rich black.

Using a clear piece of plastic sheet and working on a light box, she inks the plate up in yellow and prints that.
