A stretched artist canvas frame system is supported with a rigid foam back to either allow artists to apply pressure to a canvas without stretching it and causing sagging, or to allow artists to use the stretched artist canvas as an alternative for artists who paint on board. The frame system is a light weight alternative to painting on board, especially when the paintings become very large. The frame system provides the texture of canvas but the stiffness of a board by supporting the board with a lightweight rigid extruded foam. The frame system gives the artist the choice of painting on canvas or the feel of painting on board. The rigid foam back allows the artist to even create a smooth board finish if they choose through priming techniques. As the canvas gets larger, they do not get prohibitively heavier.
