N2 - We have studied jetting properties of silver nano-particle inks by laser forward transfer, emphasizing the regime where stable micro-droplet jetting is obtained. We study the effects of laser parameters on droplet jetting behaviour as well as the role of the ink properties and changes in donor ink film thickness. It was found that the printed droplet diameter shows a rather simple functional dependence on laser fluence in the stable droplet jetting regime and a well defined fluence threshold value can be defined depending on the specific ink and donor film thickness. Such functional dependence is typical of viscous inks while for lower viscosity inks the functional dependence changes from a logarithmic dependence to a linear one.
