L = Lack/Coating
T = Tranfer unit
V = Verlaengerung/Extension
Old presses have TLV beause the coating unit was installed on a Transfer unit.
New presses are LV which is L = Coater and V = Verlaengerung/Extension.
Every press with a coater had a extension not like Heidelberg which gave you a choice.
LTTLV is like a double coter with 2 stub units hwich usally have driers installed.
MAN Roland is no cheap alternative so you as good of with a MAN Roland as you are with a Heidelberg.
