1. An ink jet printing method, comprising the steps of:

A) providing an ink jet printer that is responsive to digital data signals;

B) loading said printer with an ink jet recording element comprising a non-absorbing substrate;

C) loading said printer with an ink jet ink composition comprising an aqueous ink jet ink composition comprising;

a pigment;

a polymer binder containing less than 25% of hydrophilic monomer by weight of the total polymer, which is dispersible but insoluble in aqueous media;

at least one surfactant; and

a humectant; and

D) printing on said ink jet recording element accompanied by a heating step using said ink jet ink composition in response to said digital data signals.

- - 2. The method of claim 1 wherein said non-absorbing substrate is a plastic, glass or metal substrate.
  - 3. The method of claim 2 wherein said plastic substrate is untreated vinyl.
  - 4. The method of claim 1 further comprising an in-situ heating step using a heating means wherein said ink jet recording element is heated to elevated temperature during the printing.
  - 5. The method of claim 4 wherein said temperature is between about 30°
    - C. to about 90°
      
      C.
  - 6. The method of claim 4 wherein said temperature is between 40°
    - C. to about 70°
      
      C.
  - 7. The method of claim 1 further comprising post-printing heating step wherein said ink jet recording element is heated to elevated temperature after printing using a heating means, wherein said temperature is between about 80°
    - C. to about 120°
      
      C.
  - 8. The method of claims 4 and 7 wherein said heating means is an irradiation source, a hot air source or an electrical heater.
  - 9. The method of claim 8 wherein said irradiation source is an infrared lamp.
  - 10. The method of claim 1 wherein the weight ratio of the said pigment to said polymer binder is 1:
    - 20 to 20;
      
      1.
  - 11. The method of claim 1 wherein said pigment comprises up to 10% by weight of the ink composition.
  - 12. The method of claim 1 wherein said pigment has an average particle size of less than 0.5 micron.
