ABSTRACT:
A web-offset printing press is provided with a first rotatable printing cylinder adapted to print a first image on a web by applying a heat-settable ink to the web, a second rotatable printing cylinder adapted to print a second image on the web, the second image being printed on the web subsequent to the first image being printed on the web by applying a heat-settable ink to the web, a drying station for drying the heat-settable ink applied to the web by the first and second rotatable printing cylinders by heating the web to an initial temperature, and a cooling station disposed adjacent the drying station, the cooling station receiving the web after the web has been heated by the drying station, the cooling station causing the initial temperature of the web to be reduced by at least about 20.degree. F. The cooling station generates a directed electrostatic field through which the web passes and sprays liquid droplets onto the web to cool the web by evaporation of the liquid droplets from the web, the electrostatic field causing the liquid droplets to pass through a confined path between spray nozzles and the web.
