Yes, intaglio is considered the opposite of relief printing. In relief printing, the image is raised above the surface, and ink is applied to the raised areas, while in intaglio, the image is incised into a surface, and ink fills the recessed lines or grooves. When printed, relief methods produce an image that stands out, whereas intaglio produces an image that is sunken or embedded. Both techniques offer unique artistic effects and are widely used in printmaking.

The first modern athletic shoe, often considered a "trainer," was created in 1892 by the U.S. Rubber Company, which produced the "Keds" sneaker.
