2. The ink-jet ink set of claim 1, wherein the dye is selected from:

3. The ink-jet ink set of claim 1, wherein the dye is selected from:

4. The ink-jet ink set of claim 1, wherein the dye is selected from:

5. The ink-jet ink set of claim 1, further comprising a second dye that is a sulfonated non-metalized azo dye with a SO₃H molecular weight percent of from 10 to 27%.

6. The ink-jet ink set of claim 5, wherein the dye is a magenta dye, wherein the second dye is selected from a yellow dye and a black dye.

7. The ink-jet ink set of claim 6, wherein the dye is selected from:

8. The ink-jet ink set of claim 6, wherein the second dye is selected from:

9. The ink-jet ink set of claim 6, wherein the second dye is selected from:

10. The ink-jet ink set of claim 5, wherein each of the first dye and the second dye are sulfonated non-metalized azo dye with a SO₃H molecular weight percent of from 15 to 27%.

11. The ink-jet ink set of claim 5, wherein each of the first dye and the second dye are sulfonated non-metalized azo dye with a SO₃H molecular weight percent of from 18 to 27%.

12. The ink-jet ink set of claim 1, wherein each of the first dye and the second dye are sulfonated non-metalized azo dye with a SO₃H molecular weight percent of from 15 to 27%.

13. The ink-jet ink set of claim 1, wherein each of the first dye and the second dye are sulfonated non-metalized azo dye with a SO₃H molecular weight percent of from 18 to 27%.

14. The ink-jet ink set of claim 1, further comprising a waterfast cyan dye.

15. A printer system, comprising:

a dispensing system including a substrate and at least one printhead,

wherein the substrate includes a multivalent salt associated with the substrate, wherein the multivalent salt is selected from Group II metal, Group III metals, and multivalent transition metals,

wherein the printhead includes at least one of an ink-jet set, wherein the ink-jet set includes a first ink and a second ink;

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 one dye selected from a magenta dye, a yellow dye, and a black dye, and wherein the dye is a sulfonated non-metalized azo dye with a SO₃H molecular weight percent of from about 10 to 27%.

16. The printer system of claim 15, wherein the ink-jet set further comprising a second dye that is a sulfonated non-metalized azo dye with a SO₃H molecular weight percent of from 10 to 27%.

17. The printer system of claim 15, wherein the one of the first dye and the second dye are selected from:

18. The printer system of claim 15, wherein the one of the first dye and the second dye are selected from:

19. The printer system of claim 15, wherein the one of the first dye and the second dye are selected from:

20. The printer system of claim 15, further comprising a waterfast cyan dye.

21. The printer system of claim 15, wherein the multivalent salt includes a metal selected from the group consisting of calcium, magnesium, copper, nickel, zinc, barium, iron, aluminum, and chromium.

22. A printing material, comprising:

a substrate that includes a multivalent salt associated with the substrate, wherein the multivalent salt is selected from Group II metal, 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 one dye selected from a magenta dye, a yellow dye, and a black dye, and wherein the dye is a sulfonated non-metalized metalized azo dye with a SO₃H molecular weight percent of from about 10 to 27%,

wherein the first ink and the second ink are disposed on the substrate.

23. The printing material of claim 22, wherein the ink-jet set further comprising a second dye that is a sulfonated non-metalized azo dye with a SO₃H molecular weight percent of from 10 to 27%.

24. The printing material of claim 22, wherein the one of the first dye and the second dye are selected from:

25. The printing material of claim 22, wherein the one of the first dye and the second dye are selected from:

26. The printing material of claim 22, wherein the one of the first dye and the second dye are selected from:

27. The printing material of claim 22, further comprising a waterfast cyan dye.

28. The printing material of claim 22, wherein the multivalent salt includes a metal selected from the group consisting of calcium, magnesium, copper, nickel, zinc, barium, iron, aluminum, and chromium.

29. A method of printing, comprising:

providing a substrate that includes a multivalent salt associated with the substrate, wherein the multivalent salt is selected from Group II metal, 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 one dye selected from a magenta dye, a yellow dye, and a black dye, and wherein the dye is a sulfonated non-metalized azo dye with a SO₃H molecular weight percent of from about 10 to 27%; and
