1. A recording sheet, comprising a web of cellulosic fibers; anda composition comprising a binder and a divalent metal salt, wherein said composition is applied to at least one surface of said web such that an effective concentration of divalent metal salt is located a distance that is within 25% from the at least one surface of said substrate and at least a majority of a total concentration of the divalent metal salt is located a distance that is within 25% from the at least one surface of said substrate. 2. The recording sheet according to claim 1, wherein the paper substrate and sizing agent cooperate to form an I-beam structure. 3. The recording sheet of claim 2, wherein said salt is present in an amount of 2.5-165 mol of cations/ton of paper substrate. 4. The recording sheet of claim 2, wherein the sizing agent further comprises at least one selected from the group consisting of starch, pigment, and a combination thereof. 5. The recording sheet of claim 2, wherein, when said sheet further comprises a printed image thereon, the image exhibits an average color gamut of about 120,000 or greater. 6. The recording sheet of claim 2, wherein, when said sheet further comprises a printed image thereon, the image exhibits a black density of about 1 or greater. 7. The recording sheet of claim 2, wherein the sizing agent is applied at a size press. 8. The recording sheet according to claim 2, having: a percent ink transferred (IT %) of less than or equal to about 60. 9. The recording sheet according to claim 2, having: a hygroexpansivity of from 0.6 to 1.25%. 10. The recording sheet according to claim 2, having: a CD Internal Scott Bond of not more than 300 J/m2. 11. The recording sheet according to claim 2, having: an MD Internal Scott Bond of not more than 300 J/m2. 12. The recording sheet according to claim 2, having: a printed image thereon, the image exhibits an edge acuity (“EA”) of less than about 15. 13. The recording sheet according to claim 1, having: a percent ink transferred (IT %) of less than or equal to about 60; anda CD Internal Scott Bond of not more than 300 J/m2. 14. The recording sheet according to claim 1, having: a percent ink transferred (IT %) of less than or equal to about 60; andan MD Internal Scott Bond of not more than 300 J/m2. 15. The recording sheet according to claim 1, having: a hygroexpansivity of from 0.6 to 1.25%; anda CD Internal Scott Bond of not more than 300 J/m2. 16. The recording sheet according to claim 1, having: a hygroexpansivity of from 0.6 to 1.25%; andan MD Internal Scott Bond of not more than 300 J/m2. 17. The recording sheet according to claim 1, having: wherein, when said sheet further comprises a printed image thereon, the image exhibits an edge acuity (“EA”) of less than about 15; anda CD Internal Scott Bond of not more than 300 J/m2. 18. The recording sheet according to claim 1, having: a printed image thereon, the image exhibits an edge acuity (“EA”) of less than about 15; andan MD Internal Scott Bond of not more than 300 J/m2. 19. The recording sheet according to claim 1, wherein said effective concentration of said divalent metal salt is selected such that the black density is at least 1.15. 20. The recording sheet according to claim 1, wherein said effective concentration of said divalent metal salt is at least 6000 ppm. 21. A method for making a recording sheet, comprising: contacting a paper substrate comprising a plurality of cellulosic fibers; anda size press formulation comprising a water soluble divalent metal salt;to produce a recording sheet in which the paper substrate and a sizing agent comprising the water soluble divalent metal salt cooperate to form an I-beam structure. 22. The method of claim 21, wherein the contacting is carried out at a size press.
