ABSTRACT:
The photoresist barrier layer of an inkjet printer printhead is processed to enable channels narrower than a predetermined width in the barrier layer to be created without blockage. Relatively large volumes of photoresist which form a wall of the channel are exposed to a partial exposure of electomagnetic radiation to yield a reduced concentration of photoresist barrier layer in the large volume.
