Ink in Tubes is a tiny, part-time hobby operation supplying small quantities of ink (usually 5-oz. tubes) to letterpress printers in the U.S.; most of the ink is oil-base, and is available in metallics and fluorescents as well as Pantone basics and many, many premixed Pantone colors. Ink tube labels and boxes are all printed letterpress from handset type, on a century-old Multigraph press.
