Printing paper for a rotary press industrial ink jet printer and a method for producing printed matter

摘要

PROBLEM TO BE SOLVED: To provide a printing paper for a rotary type industrial inkjet printer having printability for an offset printer, excellent in color concentration uniformity, striking-through inhibition property and dot reproducibility for the rotary type industrial inkjet printer using an aqueous pigment ink.SOLUTION: The problem is solved by a printing paper for a rotary type industrial inkjet printer having a base paper, and one or more coated layer containing a pigment, a binder and a water soluble multivalent cation salt on at least one surface of the base paper, where at least one kind of the pigment is kaolin having an average particle diameter of 0.20 μm to 1.50 μm inclusive, the content of the kaolin in the coated layer is 50 pts.mass or more based on 100 pts.mass of the pigment, the content of the water soluble multivalent cation salt in the coated layer is 1.0 pts.mass to 6.0 pts.mass inclusive based on 100 pts.mass of the pigment, and a surface resistance rate of a coated layer surface side having the coated layer under environment of 23°C and 50% RH required according to JIS K 6911:2006 of 2.0×10Ω to 5.0×10Ω inclusive.SELECTED DRAWING: None
