As printing technology continues to evolve, the next technical challenges will most likely arise from fully automated digital print production and high-precision digital fabrication, where the printing press needs to detect faults in the printing process, automatically recover without human intervention, and construct images and/or three-dimensional objects beyond the capability of human perception. In this paper, we introduce a computational image formation algorithm of which tonal resolution at each pixel is elevated from the current technology standard of 8-bit to a class-leading 12-bit, i.e., 4K tonal resolution. Combined with a 1200-dpi high spatial resolution adaptive LED printhead, we will demonstrate that the proposed image formation algorithm can effectively address technological challenges for the future of image formation and digital fabrication technologies.
