A decorated printed matter which comprises: a plastic plate 1 with a light permeability, the plastic plate 1 is made of poly carbonate and is provided a convexo-concave pattern consists of a plurality of fine grooves 2 in the form of spin line on a rear-side surface 1b thereof; an ink coating 3 covering the convexo-concave pattern; and the ink coating 3 is formed by removing a solvent from an ink composition coated on the rear-side surface 1b of the plastic plate, the ink composition includes a carbon black and a binder; the average ratio of carbon black to binder is determined such that the distribution of the black pigment in the ink coating becomes the distribution by which an incident light incoming into the resin substrate from the front-side surface thereof reflects at an interface between the resin substrate and the ink coating. ## Claims ### Claim 1 A decorated printed matter comprising: a resin substrate with a light permeability, the resin substrate has a convexo-concave pattern, which consists of a plurality of grooves, on a rear-side surface thereof; and an ink coating covering the convexo-concave pattern; wherein: the convexo-concave pattern is visible from a front-side of the resin substrate, the ink coating is formed by removing a solvent from an ink composition coated on the rear-side surface of the resin substrate, the ink composition includes a coloring pigment as colorant and a binder as an adhesive, the coloring pigment has a non-metallic appearance before being added to the ink composition, and wherein a ratio of the coloring pigment to the binder is within a range of 0.27 to 1.40, such that the distribution of the coloring pigment in the ink coating becomes the distribution by which an incident light incoming into the resin substrate from the front-side surface thereof reflects at an interface between the resin substrate and the ink coating. ### Claim 2 (depends on 1) A decorated printed matter according to claim 1, wherein the decorated printed matter is a product of a process in which, before the solvent is evaporated therefrom, the ink composition includes a first solvent and a second solvent, a solubility of the resin substrate in the second solvent is higher than that of the resin substrate in the first solvent, a ratio of the first solvent to the second solvent is determined to the ratio at which the convexo-concave pattern is not spoiled by the solvent during the period of time from the coating of the ink composition on the resin substrate to the removal of the solvent from the ink composition by drying. ### Claim 3 (depends on 2) A decorated printed matter according to claim 2, wherein the first solvent is at least one selected from among the group of buthyl cellosolve, ethyl cellosolve, cyclohexane, and ethyl cyclohexane, the second solvent is at least one selected from among the group of cyclohexanone, 1,3,5-trimethylbenzene, 1,2,4-trimethylbenzene, propylene glycol monomethyl ether acetate, isophorone, butyl acetate, toluene, xylene, cumene, and ethyl benzene. ### Claim 4 (depends on 1) A decorated printed matter according to claim 1, wherein the coloring pigment is at least one of a black pigment, a blue pigment, a red pigment, a purple pigment, a green pigment and a yellow pigment. ### Claim 5 (depends on 4) A decorated printed matter according to claim 4, wherein the black pigment is a carbon black. ### Claim 6 (depends on 2) A decorated printed matter according to claim 2, wherein the coloring pigment is at least one of a black pigment, a blue pigment, a red pigment, a purple pigment, a green pigment and a yellow pigment. ### Claim 7 (depends on 6) A decorated printed matter according to claim 6, wherein the black pigment is a carbon black. ### Claim 8 (depends on 3) A decorated printed matter according to claim 3, wherein the coloring pigment is at least one of a black pigment, a blue pigment, a red pigment, a purple pigment, a green pigment and a yellow pigment. ### Claim 9 (depends on 8) A decorated printed matter according to claim 8, wherein the black pigment is a carbon black. ### Claim 10 A decorated printed matter consisting of: a resin substrate with a light permeability, the resin substrate has a convexo-concave pattern, which consists of a plurality of grooves, on a rear-side surface thereof; and an ink coating covering the convexo-concave pattern; wherein: the convexo-concave pattern is visible from a front-side of the resin substrate, the ink coating is formed by removing a solvent from an ink composition coated on the rear-side surface of the resin substrate, the ink composition includes a coloring pigment as colorant and a binder as adhesive, the printed matter generates a metallic luster when incident light is reflected from the ink coating through the resin substrate, the coloring pigment has a non-metallic appearance before being added to the ink composition, a rear surface of the ink coating spaced away from the resin substrate is uncovered and open to the environment, and the distribution of the coloring pigment in the ink coating reflects an incident light, incoming into the resin substrate from the front-side surface thereof, from an interface between the resin substrate and the ink coating.
