ABSTRACT:
An ink jet channel wafer for an ink jet printer has a first surface in which a plurality of anisotropically etched ink channels and an anisotropically etched ink reservoir are directly connected to one another. The ink jet channel wafer is etched using an admixture of at least one alkali metal hydroxide and at least one alcohol compound.
