Abstract:
A method for manufacturing an ink jet print head, comprising the steps of:partially fabricating the ink jet head, including forming a plurality of ink grooves on a substrate; determining values for ejection factors, that as a combination influence ejection of ink, wherein a groove depth and a groove width of the ink grooves are selected as the combination of ejection factors; subsequently measuring one of the groove depth and the groove width of the partially fabricated ink jet print head to monitor a deviation of the values from a standard range; re-determining the other one of the groove depth and the groove width based upon the deviation from the standard range of at least one measured ejection factor so that in use, ink in a resultant ink jet print head is ejected in a predetermined ejection state; and completing fabrication of the inkjet print head, including forming of the redetermined other of the groove depth and the groove width to form the resultant ink jet print head.
