In 1971 the Mark III web offset design was introduced, with versions capable of printing up to 4 webs simultaneously.
In the early 1970s these very versatile machines were being produced at the rate of 3 to 4 machines per month for customers all over the world. The 'Wun-Up' was the mainstay of the Company for over 20 years. The last press was despatched in 1993 to the Government Printer in Tanzania, by which time the Wun-Up had been superseded by the T24.
