Abstract:
A process of minimizing fluting in a web of light weight coated paper printed on both sides with thermosetting ink in a heat-set web-offset printing press having a floater type drying oven and one or more chill rolls downstream from the oven for cooling the printed and heated web and including a smooth surfaced chill roll immediately downstream from the oven, comprising the steps of:pulling the printed web through the oven and the chill rolls free of any intervening pressure nips,contacting the printed web as it passes from the exit end of the oven with a convexly curved surface to spread the web transversely of its length during passage of the web through at least a downstream end portion of the floater oven and during passage of the web from the oven to the chill roll immediately downstream from the oven and contacting the transversely spread printed web with the smooth surface of said chill roll to hold the web in a transversely spread and flat condition during cooling.
