“The finest letterpress machines ever made”
The fundamental advantage of a cylinder press is that the impression of paper on type only has to be delivered in a small strip — the point where the cylinder touches paper and type. Other presses have to get an impression across the whole area of the type at once. This means cylinder presses can use a greater force with greater prescicison that their platen equivalent.
Heidelberg clinder presses are claimed by many to be the peak of prescision letterpress work at volume. Their 1958 offerings are detailed below in specification and pictures from brochures.
