How does the upscaling algorithm work?

Before being printed as physical artworks, the generated artworks are upscaled to a resolution of 16K using a machine learning algorithm. A generative adversarial network was fine-tuned on a historical catalogue of more than 2,000 of Damien Hirst’s ‘Spin Paintings’ to upscale the artwork to a resolution of 16K, allowing the artwork to maintain intricate details and structure at a larger size.
