3d printed paintings12/19/2023 ![]() Sarah Cascone of artnet News reports that the researchers’ method, known as “color-contoning,” works in conjunction with the established technique of half-toning, or applying ink via tiny dots rather than continuous fields of color. RePaint replicates oil paintings’ tones with a level of accuracy evident across multiple lighting conditions-a quality difficult to capture in four-ink reproductions, which Changil Kim, co-author of a recent study detailing the technology, tells MIT News’ Rachel Gordon “might look different in your home” versus the gallery. This expanded range of colors makes it possible to conjure up more accurate replicas of stolen masterpieces such as Johannes Vermeer’s “ The Concert” and the “ Just Judges” panel of Jan and Hubert van Eyck’s Ghent Altarpiece, as well as carbon copies of fragile canvases otherwise accessible only through a museum visit. ![]() Comparatively, traditional 2D printers typically operate in CMYK, or cyan, magenta, yellow and black, which is the keyline color. RePaint, a resin-based 3D printer that renders reproductions in color four times closer to the original than the next-best tool, utilizes a palette of 11 different inks: cyan, magenta, yellow, black, green, blue, orange, red, violet, transparent white and opaque white. A new method of multi-layer, custom-ink 3D printing pioneered by the Massachusetts Institute of Technology’s Computer Science and Artificial Intelligence Laboratory (CSAIL) could transform the way we reproduce art, Sam Gaskin reports for Artsy.
