The design of illustration boards is to provide a rigid, sturdy art surface with a paper surface on a thick backing, ideal for various artistic applications including pen and ink, airbrush, watercolor, gouache, acrylics, pencil, and marker renderings. The hard, rigid backing prevents buckling from media like watercolors, and its varied textures.
