Use a clean sable brush to lightly dust off the canvas. If something is inadvertently splashed onto the serigraph on canvas, take a slightly dampened soft cloth to clean off the spill. I want to emphasis that these instructions are just to clean a Will Moses serigraph on canvas, and are not recommended for all serigraphs. Inks vary from printer to printer. Improper cleaning may damage a lesser quality canvas.
Etching is one of the oldest art printing forms.
The artist uses tools similar to dental tools to scratch and burnish a vanish covered zinc plate. This is followed by bathing the plate in nitric acid, and burning the metal away with the acid. This basic etching process is repeated several times, depending on the image. Once the plate is complete, printing can start. The paper is dampened in order to be flexible enough to contour to the highs and lows of the metal etching plate.
