Abstract (en)

[origin: JP2016180581A] PROBLEM TO BE SOLVED: To provide a method of changing a relative humidity of a printing base material capable of uniformly drying the printing base material or a printed matter to be optimally applied in processing of a printing base material web and the like and to unify a dryness with a desired residual humidity.SOLUTION: In a method of changing a relative humidity of a printing base material by a drying unit 1 including a plurality of drying elements 14 disposed in a crosswise direction with respect to a conveying direction of the printing base material and facing the direction of the printing base material to dry the printing base material with each drying strength, the drying elements can be individually controlled so that a printing base material web 2 or a printed matter can be particularly uniformly dried, as a result, the desired residual humidity can be achieved, and the optimum and uniform dryness for processing of the printing base material web and the like can be achieved. For this purpose, at least two drying elements are controlled so that different drying strengh is applied to at least each of two regions in the crosswise direction to the conveying direction of the printing base material.SELECTED DRAWING: Figure 1
