Dutch printmaker, gold- and silversmith and draughtsman, son of Johannes Lutma the Elder. He became a master in 1643. In 1651 he was in Rome, where he made drawings (e.g. the Farnese Hercules, 1651; Amsterdam, Rijksmuseum) and engraved several fountains (e.g. the engraving of the fountain in Piazza Navona, 1652). In the etched portrait of his father (1656) Johannes the Younger began to exploit tonal effects through the additional use of punch and roulette. In the later hammered or punched prints of c. 1681 he managed to produce quite exceptional grey tones by a combination of roulette accents in the outlines and fine punching. //
