A method of and apparatus for curing or minimizing the problem of web "fluting" or "corrugating" in printed webs of paper printed on heat-set web-offset printing presses resides in spreading the web in its width-wise direction as the printed web exits from the ink drying and heat setting oven of the press and passes over the web cooling chill rolls downstream from the oven, thereby to hold the printed web in a flat and smooth condition until it is cooled and has taken a permanent set. The method and apparatus facilitate operation of the press at higher speeds and with lighter grades of paper than conventional, and provide for increased production efficiencies, lower costs, enhanced print quality, and access to new markets for web-offset printing.
