Interesting post from Australia on what makes a good letterpress paper.
What's special about letterpress papers?
The Artisan Press uses a range letterpress friendly papers from the leading fine art paper mills across the world. Some of these mills were producing paper in the 13th century – well before the advent of the printing press! For example the Magnani mill in Italy, customers include Napoleon Bonaparte, the reigning families of Europe and the state mints of several countries. It's a little special and one touch will tell you why.
