Abstract
A method of printing a material web includes the steps of applying ink to the material web, subsequently drying the material web with the use of heat and subsequently drying the material web, and, after cooling and prior to further processing, moistening the material web while simultaneously applying heat to the material web, and subsequently once again cooling the material web. An apparatus for carrying out the method includes, in a travel direction, a printing unit, a drying section following the printing unit, a cooling section following the drying section, a moistening section following the cooling section, and an after-cooling section following the moistening section.
