Digital photographs are images made from a digital file using a printer that applies very fine drop of ink on paper. As digital technology was developed in the early twentieth century, the question of print stability have led to the development of increasingly stable inks and papers. Materials are subjected to rigorous accelerated again tests to determine how long a photographs will last without significant fading. Today there are many options of digital rag papers and inks that are expected to last more than a century if prints are properly stored and exhibited. The terms “Archival Pigment Print” and “Giclée Print” are also used for such prints. The longevity rates of many pigment prints are calculated at over 100 years, depending on the paper used. As an ink-based process, modern digital printing has more in common with late nineteenth-century photogravures than with chromogenic prints made throughout the twentieth century.
