Droplet printing through bubble contact in the laser forward transfer of liquids

▶ A bubble contact deposition mechanism for the LIFT of liquids has been unveiled. ▶ This mechanism consists in the contact of the generated cavitation bubble with the receptor substrate. ▶ To attain the highest resolution of LIFT, the bubble contact should be avoided. ▶ This can be achieved at low fluences and/or large donor-receptor separations.
