In the past, the multi-spectrum technology used in military and medical treatment, this technological innovation is applied to the color capture of printed images, which can solve the problem of color distortion caused by RGB capture in the past. This technology can restore the true colors through the spectrum algorithm and simulate the effects of different color temperatures and material appearances. This technology is suitable for color-related industries such as printing, textiles, ceramic tiles and glazes, and can replace different spectrum filters, and can be used in jewelry identification or criminal case investigation.
