Abstract: A liquid is applied by a bounded-region applicator such as a needle applicator over nozzle holes and over at least a continuous region close to the nozzle holes. The liquid is then cured to a solid before significant flow of the liquid into the nozzle holes. The liquid is chosen to cure to a solid which is sufficiently compliant that it deforms and leaves the nozzle holes under moderate pressure from a human hand or finger without breaking. Depending upon the material in which the nozzles are formed and the size of the nozzle holes, the liquid may be uniquely designed to incorporate resilient moieties or segments to satisfy these factors.
