The Commander CL’s off-bearer printing units are precision engineered, compact yet easily accessible. The torsionally rigid box-type construction of the side frames and the new cylinder bearing guarantee a smooth press run and superb print quality. Towers that are just six metres (19ft 7in) high shorten the distance between the printing couples, reduce fan-out and, in conjunction with mechanical bustle wheels between the stacked H-type units, ensure good registration. Pneumatic bustle wheels are optional.
