摘要

When an impinged inkjet droplet is impacting a paper substrate, it evaporates to the air and penetrates into the paper. The imbibition dynamics are strongly dependant on the pore structure on the surface and inside the substrate. In this work picoliter (pL) water droplets were impinged onto two commercially available matte and gloss coated paper sample. The imbibition process was recorded and analyzed using a high speed imaging system. Calculations of the volume change were done by considering that the droplets are shaped as hemispherical caps. The total drying time of water droplets of about 60 pL is 10-15 ms on the gloss coated paper, and 30-150 ms on the matte coated paper. In addition, the two samples show different regimes in the imbibition process caused by the different porous structures present in the samples.
