What is claimed is:

1. A method of digital printing, comprising the steps of:

a. preparing a reactive ink comprising a first reagent, and a second reagent, wherein said first reagent is reactive with said second reagent; b. supplying a digital printer with said reactive ink;
c. digitally printing said reactive ink on a substrate;
d. digitally printing an ink comprising a heat activated dye on said substrate; and
e. subsequently reacting said first reagent with said second reagent to bond said reactive ink to said substrate, and heat activating said heat activated dye to fix said heat activated dye to a polymer that is present on said substrate.

2. A method of digital printing as described in Claim 1 , wherein said reactive ink comprises polymer.

3. A method of digital printing as described in Claim 1 , wherein said reactive ink comprises heat activated dye.

4. A method of digital printing as described in Claim 1 , wherein said reactive ink comprises pigment.

5. A method of digital printing as described in Claim 1 , wherein said ink comprising heat activated dye is printed over said reactive ink after said reactive ink is printed.

6. A method of digital printing as described in Claim 1 , wherein said ink comprising heat activated dye comprises polymer.

7. A method of digital printing as described in Claim 1 , wherein said first reagent comprises a functional group that reacts with active hydrogen, and said second reagent comprises active hydrogen.

8. A method of digital printing as described in Claim 1 , wherein said heat activated dye is a disperse dye.

9. A method of digital printing as described in Claim 1 , wherein said heat activated dye is a sublimation dye.

10. A method of digital printing, comprising the steps of:

a. preparing a reactive ink comprising a first reagent, a second reagent, and a heat activated dye, wherein said first reagent is reactive with said second reagent;
b. supplying a digital printer with said reactive ink;
c. digitally printing said reactive ink on a substrate; and
d. subsequently reacting said first reagent with said second reagent to bond said reactive ink to said substrate, and heat activating said heat activated dye to fix said heat activated dye to a polymer that is present on said substrate.

11. A method of digital printing as described in Claim 10, wherein said reactive ink comprises polymer.
