Abstract
A tandem printing system for imaging a continuous web of material includes a first printer serially coupled to a second printer wherein the speed of the web can be adjusted to maintain image quality and to compensate for a change in a diameter of a driver drum. The change in the diameter of the driver drum can be derived from characteristics of the printing system including the amount of sag of the continuous web of material moving between the first printer and the second printer.
