RePaint works by stacking ten different transparent inks in a thin layer, with AI predicting the ideal stack needed to produce the desired color. The team also feeds AI paintings to help determine which colors are needed in a particular painting field, adjusting for changes in lighting conditions to ensure consistency. This technology also relies on halftoning (where you make images using ink dots) to get closer to color.
Current technology cannot create surface textures and reflections, so you will not get a matted or shiny appearance of some paintings. And of course you won't get a Louvre-sized masterpiece in the near future – the current output is as big as a postcard. If and when it scales, though, RePaint can have a broad appeal. You can have a Monet or Van Gogh replica that looks more authentic in your home, while the museum can protect valuable original objects by showing reproduction whenever possible.
