Canvas white pigment and calcium carbonate is rather brittle and susceptible to cracking. As lead-based paint is poisonous, care has to be taken in using it. Various alternative and more flexible canvas primers are commercially available, the most popular being a synthetic latex paint composed of titanium dioxide and calcium carbonate, bound with a thermo-plastic emulsion. Many artists have painted onto unprimed canvas, such as Jackson Pollock, Kenneth Noland, Francis Bacon, Helen Frankenthaler, Dan Christensen, Larry Zox, Ronnie Landfield, Color Field painters, Lyrical Abstractionists and others. Staining acrylic paint into the fabric of cotton duck canvas was more benign and less
George Pusenkoff pictures from the Internet onto his computer, edits them using Photoshop, enlarges or reduces sections, erases them with a digital eraser, etc. He then uses the computer to create his works. In the next work step a plotter produces films, in which the represented motif dissolved in light and dark, and the parts previously marked by Pusenkoff are pre-punched. They are cut out of the foils and transferred to the canvas. The artist then applies eight to twelve layers of acrylic paint, partly mixed with sand, so that relief-like raised parts form in the picture. This technique of image processing
