1. An ink-jet ink set, comprising:
- a first ink and a second ink, wherein the first ink and the second ink are different dye colors, wherein each of the first ink and the second ink include at least a first respective sulfonated non-metalized azo dye with a SO3H molecular weight percent of from about 10 to 27%, wherein said first dye is capable of complexing with a multivalent salt associated with a paper substrate when said inks are deposited on a print medium containing said paper substrate with associated multivalent salt,said first and second inks having enhanced waterfastness when disposed on said print medium, compared to a print medium without said multivalent salt.

15. A printer system, comprising:
-
a dispensing system including a paper substrate and at least one printhead, wherein the paper substrate includes a multivalent salt associated with the paper substrate, wherein the multivalent salt comprises a metal selected from the group consisting of Group II metals, Group III metals, and multivalent transition metals, and wherein the printhead includes an ink-jet ink set comprising; a first ink and a second ink, wherein the first ink and the second ink are different dye colors, wherein each of the first ink and the second ink include at least a first respective sulfonated non-metalized azo dye with a SO3H molecular weight percent of from about 10 to 27%, wherein said first dye is capable of complexinq with said multivalent salt associated with said paper substrate when said inks are deposited on a said paper substrate with associated multivalent salt, and wherein said first and second inks have enhanced waterfastness when disposed on the paper substrate containing said multivalent salt, compared to a paper substrate without said multivalent salt. - View Dependent Claims (16, 17, 18, 19, 20, 21)

22. A printing material, comprising:
-
a print medium that includes a multivalent salt associated with a paper substrate, wherein the multivalent salt comprises a metal selected from the group consisting of Group II metals, Group III metals, and multivalent transition metals; and a first ink and a second ink, wherein the first ink and the second ink are different dye colors, wherein each of the first ink and the second ink include at least a first respective sulfonated non-metalized azo dye with a SO3H molecular weight percent of from about 10 to 27%, wherein said first dye is capable of complexinq with a multivalent salt associated with a paper substrate when said inks are deposited on said print medium containing said paper substrate with associated multivalent salt, and wherein the first ink and the second ink are disposed on the print medium and said sulfonated non-metalized azo dyes are complexed with said multivalent salt to decrease solubility of said deposited dyes, compared to a print medium without said multivalent salt. - View Dependent Claims (23, 24, 25, 26, 27, 28)

29. A method of printing, comprising:
providing a print medium that includes a multivalent salt associated with a paper substrate, wherein the multivalent salt comprises a metal selected from the group consisting of Group II metals, Group III metals, and multivalent transition metals; providing a first ink and a second ink, wherein the first ink and the second ink are different dye colors, wherein each of the first ink and the second ink include at least a first respective sulfonated non-metalized azo dye with a SO3H molecular weight percent of from about 10 to 27%, wherein said first dye is capable of complexing with said multivalent salt associated with said paper substrate when said inks are deposited on said print medium; depositing the first ink and the second ink on the print medium, and causing said sulfonated non-metalized azo dyes to complex with said multivalent salt to decrease solubility of said dyes, to provide a printing material with improved waterfastness, compared to a printed medium without said multivalent salt. - View Dependent Claims (30, 31, 32, 33, 34, 35)
