   RESOLUTION — an exhibition about the Renaissance image after
   reproduction. Institute for Image Studies (fictional).

   The whole design argument is one collision: a typeface descended
   from 16th-century punchcutting (EB Garamond) set against the
   monospace and bitmap faces of the machines that now carry those
   images. Nothing else needs to shout — the plates dither themselves.
