Abstract
Methods and apparatus are provided related to fluid dispensing heads. A dispense head is formed to define a plurality of fluid jetting nozzles and a surface pattern. The surface pattern is characterized by one or more voids extending inward from an outer surface of the dispense head. Fluid puddle formation during operation of the dispense head is limited in volume by way of the surface pattern. Fluid puddle limiting reduces or eliminates dispensing errors to an entity, undesirable artifacts from resulting on a printed media, or similar problems.
