Abstract: The invention relates to a paper product formed from fiber-based source material and applicable as printing paper. According to the invention, the surface of the paper product is finished by providing sufficient density on the surface so that the density of at least one surface layer of the paper product is sufficiently high to yield a Gurley-Hill value of more than 7000 s/100 ml as measured from the entire paper product, and the paper product has been dried to a moisture content of less than 3.5%. In addition, the invention relates to a process for manufacturing a paper product.

Abstract: The invention relates to a paper that is formed of a fiber-based source material and is applicable as printing paper. According to the invention, the surface of the paper is surface-treated by arranging on the surface sufficient density in such manner that the density of at least one surface layer of the paper is sufficiently high to yield a Gurley-Hill value of over 7000 s/100 ml as measured from the entire paper. Furthermore, the invention relates to a method for making paper.

Abstract: The invention relates to a paper that is formed of a fiber-based source material and is applicable as printing paper. According to the invention, the surface of the paper is surface-treated by arranging sufficient density on the surface, such that a mixture is arranged at least on one side of the surface of the paper for forming a surface layer, which mixture comprises pigments in an amount of 75-95% by weight of the dry weight and bonding agent in an amount of 5-25% by weight of the dry weight, and the porosity of the surface layer of the paper is less than 0.07 ml/g as defined by mercury porosimeter process. Furthermore, the invention relates to a method for making paper.
