Digby & Rose
/Wasington, DC art studio Digby & Rose developed a printing technique known as the Compression Plate Process (tm) that "enhances the rich texture of regular letterpress printing, resulting in a 50% deeper press." It also really makes the colors pop and adds a lot of flexibility not always available with letterpress.
We sent them two dozen(ish) papers to experiment with to see how their process performs across a range of different papers. We'll report back in a few weeks.
