What makes a 500-year-old printing process new? Master printer and publisher Jacob Samuel has brought etchings—prints created by transferring ink from a metal plate to paper—into the 21st century through collaborations with more than 60 contemporary artists. In this video, MoMA filmed Samuel making his last print. As he inks, hand wipes, and rolls his final print through the press, he reflects on his philosophy. “My goal is to leave no fingerprints,” he says. "All you see is the artist’s work. I’m just another pencil. I’m just another brush. But I want the pencil to be sharpened really well. I want the brush to be sable. And to do that and be completely spontaneous, I trust the materials.”
