    Abstract: A method for preparing a printable substrate having a showthrough value of about 0.14 or less, and an opacity value of at least about 88% which includes a paper substrate with a first and second surfaces formed of paper fibers having a basis weight of from about 12 to about 32 lbs/1300 ft2, and a substrate filler in an amount in the range of from 0 to about 30% by weight of the paper substrate; and a surface size layer on at least one of the first and second surfaces, the surface size layer having about 50 lbs or less per ton of the paper substrate of a starch surface sizing agent and a multivalent metal salt drying agent in an amount sufficient to impart to the at least one of the first and second surfaces a black print density value of at least about 0.8 when inkjet printed with pigmented inks and a waterfastness value of at least about 85% when inkjet printed with dye-based inks, the printable substrate having a MD tensile strength of at least about 12 lbs/in. and a CD tensile strength of at least about 6 lbs/in.

    Abstract: An article in the form of a printable substrate having a showthrough value of about 0.14 or less, and an opacity value of at least about 88% which includes a paper substrate with a first and second surfaces formed of paper fibers having a basis weight of from about 12 to about 32 lbs/1300 ft2, and a substrate filler in an amount in the range of from 0 to about 30% by weight of the paper substrate; and a surface size layer on at least one of the first and second surfaces, the surface size layer having about 50 lbs or less per ton of the paper substrate of a starch surface sizing agent and a multivalent metal salt drying agent in an amount sufficient to impart to the at least one of the first and second surfaces a black print density value of at least about 0.8 when inkjet printed with pigmented inks and a waterfastness value of at least about 85% when inkjet printed with dye-based inks, the printable substrate having a MD tensile strength of at least about 12 lbs/in. and a CD tensile strength of at least about 6 lbs/in. Also, a method for preparing such a printable substrate.
