Method and composition for ink jet printing on a nonabsorbent substrate

Ink jet printing on a non-absorbent substrate involves a wet primer having a primer viscosity. The wet primer is applied on the non-absorbent substrate. An ink jet ink having an ink jet viscosity lower than the primer viscosity is jetted over the wet primer while the primer is still wet. The wet primer and ink are simultaneously cured on the substrate.
