In a web manufacturing process according to the present invention, the process includes at least one print station adapted to print enzymes on a moving substrate. In one embodiment, the web manufacturing process includes continuously moving the substrate, depositing enzyme ink onto the substrate through a screen printing process wherein ink is deposited on a top side of the screen and forced through the top side onto the substrate which is positioned adjacent to the bottom side of the screen. In order to improve ink transfer, air at the top side of the screen is humidified to a first relative humidity and air at the bottom side of the screen is humidified to a second relative humidity.
