Quite likely, every bookbinder and book conservator located in North America has used Mohawk Superfine paper. It’s a wonderful paper for many applications: textblocks for models, endpapers for circulating collections, lining boards and spines, labels, and so on.
Surprisingly, at least to me, the name does not come from 1970s urban slang, or the 1960s Garage Rock band The Superfine Dandelion, but was coined in 1946.
Mohawk originally developed Superfine as the result of a challenge from Yale University Press to produce an attractive, archival text paper for their reprint of The Papers of Benjamin Franklin. A Mohawk representative showed a sample of the new paper to a customer in Boston, who reportedly said, “this is a superfine sheet of paper.”
