Jan Lutma the Younger

1624–1689, Amsterdam

Born in Amsterdam in 1624, Jan Lutma the Younger worked as an engraver and silversmith, becoming a master in 1643. In 1651 he was in Rome. No confirmed specimens of his work as a silversmith are known to exist, but he did produce a small printed oeuvre consisting of portraits and ornamental engravings. He is also considered to be the inventor of a tonal printing method known as opus mallei, a stippling technique derived from goldsmiths’ workshops, in which a burin and hammer (malleus in Latin) are used to achieve fine tonal transitions on the copperplate.
