In 1505–1507, Dürer created six decorative woodcuts with different ornaments which received the name The Knots. It is a completely new approach to a woodcut. The artist worked with wood as if it was a copperplate: with his knife, he deepened the lines that were to stay white when impressed; the untouched surface of the plate was the black background. It is an intaglio printing technique, the surface of the plate and not the relief lines being printed.
