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.

1. A paper that is formed of a fibre-based source material and is applicable as printing paper, wherein the surface of the paper is surface-treated by arranging a 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
1. A paper that is formed of a fibre-based source material and is applicable as printing paper, wherein the surface of the paper is surface-treated by arranging a 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, wherein the mixture comprises a pigment in an amount of 75-95% by weight based on the total dry weight of the mixture and a bonding agent in an amount of 5-25% by weight based on the total dry weight of the mixture, and the porosity of the surface layer of the paper is less than 0.07 ml/g as defined by mercury porosimeter process, and wherein the paper is applicable as printing paper in HSWO printing. 2. The paper according to claim 1, wherein the porosity of the surface layer of the paper is less than 0.06 ml/g as defined by the mercury porosimeter process. 3. The paper according claim 1, wherein the pigment is selected from the group of: kaolines, talcs, carbonates, gypsum and mixtures thereof. 4. The paper according to claim 1, wherein a plate-shaped pigment is used at least partly as the pigment. 5. The paper according to claim 1, wherein the bonding agent is selected from the group of: starches, proteins, latexes, carboxy-methyl cellulose, polyvinyl alcohol, mixtures thereof and the like. 6. The paper according to claim 1, wherein the mixture comprises pigment in an amount of 82-92% by weight based on the total dry weight of the mixture. 7. The paper according to claim 1, wherein the mixture comprises the bonding agent in an amount of 8-17% by weight based on the total dry weight of the mixture. 8. The paper according to claim 1, wherein the paper is calendered. 9. A method for making paper, wherein paper that is applicable as printing paper is formed of a fibre-based source material, wherein paper is surface-treated such that it is coated at least on one side with a mixture comprising a pigment in an amount of 75-95% by weight based on the total dry weight of the mixture and a bonding agent in an amount of 5-25% by weight based on the total dry weight of the mixture, for arranging sufficient density on the surface of the paper and forming a surface layer in such manner that the porosity of the surface layer is less than 0.07 ml/g as defined by mercury porosimeter process, and wherein the paper is applicable as printing paper in HSWO printing. 10. The method according to claim 9, wherein sufficient density is arranged on the surface layer of the paper in such manner that the porosity of the surface layer is less than 0.06 ml/g as defined by the mercury porosimeter process. 11. The method according to claim 9, wherein the ratio of the pigment to the bonding agent is controlled. 12. The method according claim 9, wherein the paper is calendered.
