Unlike Robert Estienne, who kept his punches for his own publications, Claude Garamont sold his typefaces, which became widespread during his lifetime. Parisian booksellers and printers purchased fonts from Garamont, including Conrad Neobar in 1540 (in particular a roman Cicero), Mathurin Du Puys in 1541, Etienne Mesvière in 1543, Guillaume Godard prior to 1545 and Denis Du Vau before 1556.

It should be pointed out that in 1545, Claude Garamont took part in the publication of a set of small-format works by supplying the typefaces, and specifically an italic "glossa" that he had just completed. The Greek characters that Garamont created for the king were initially exclusively reserved for the royal Greek printers, which increased their fame but limited their circulation, even though the alphabets published by Robert Estienne transmitted the beauty and the variety of these new characters.
It is interesting to observe the sale of Garamont's punches and matrices in the Paris market at the mid-century point, before the arrival of Christophe Plantin who, after he set up shop as a printer in Antwerp, owned 162 matrices of "Garamont petit Romain 1556", and prior to the explosion of French fonts available on the European market.
