Although the language isn’t English – this is a video tutorial of a print shop in Paris that prints lithographs. Such an art form – at about 2 minutes in, you can see that the registration of the press is actually set by hand.
Some of you may remember a while back that I had posted about antique printing stones – I really want one for my personal collection. Look how many line the walls of this old print shop.
