Improving Printability on a Sheet-fed Offset Press With Continuous Dampening System Upgrade
Abstract
Increasing demand for shorter run lengths - as small as 200 copies - and having the ability to be profitable while
producing printed products that conform to a relevant printing standard has been a continuous challenge for
many sheet-fed offset printers. To be profitable means getting the job done with shorter press makeready time,
better inking uniformity, and better color and registration consistency over time. This paper investigates the effect
of the continuous dampening system on printability of a sheet-fed offset press. The results compare the printability
differences between the continuous and the conventional dampening system.
