A stencil is made up for each colour of the image and put over a fine fabric mesh that is stretched over a metal frame. The coloured ink is spread over the mesh and stencil and the ink falls through the stencil to the underlying material (usually an art paper) to produce the image. The surplus ink is washed away. Once the ink has dried the next stencil (i.e. the next colour) is placed and the process begins again.
