Our study represents the first investigation of imbibition of ink-jet deposited nano-Cu colloid drops on a proprietary coated paper substrate. Using high speed imaging apparatus to capture the depsoition of ink-jet drops, the timescales of drop spreading and imbibition are quantified and compared to the model predictions. The influences of the coating pore size on the bulk absorption rate and nano-Cu particle distributions have also been studied for this work.
