If you'd like to use this sort of ink in a hands-on way, without a multimillion dollar computerized commercial offset press or anything, look for a local arts institution's course in letterpress or intaglio printmaking. (The latter is more drawing-oriented than the former.) It's rather fun. You also get to use some really nice paper, too.

You can find this sort of ink in squat little tins in the right art supplies store.
