Inkjet printer with in-flight droplet drying system

An inkjet printing system comprising:

• a plurality of inkjet printheads, each printhead having nozzles for jetting ink droplets having a first concentration of vaporizable carrier fluid;
• a support structure to which the plurality of inkjet printheads are mounted, such that a face of each of the printheads of the plurality of printheads is positioned to jet the ink droplets toward a target area through which a receiver transport system moves a receiver during printing;
• a condensation shield between the support structure and the target area creating a first region between the support structure and the shield with the shield having at least one opening through the shield through which the nozzles of the printhead can jet the ink droplets to the target area;
• a heat shield between the condensation shield and support structure dividing the first region into a thermally elevated region between the heat shield and the condensation shield and a thermally insulated region between the support structure and the thermal shield, with the heat shield having at least one opening through the heat shield through which the nozzles which the nozzles of the printhead can jet the ink droplets to the target area;
• and
• an energy source supplying energy to cause the condensation shield to heat to a temperature that is above a condensation temperature of carrier fluids in the inkjet ink and that causes heating of the thermally elevated region to accelerates evaporation of the carrier fluid in the ink droplets so that the droplets create a spot size that corresponds to a spot size of an equivalent ink drop having a second concentration that is at least 1% greater that than the first concentration without such heating.
