    摘要: An apparatus and method for accurately and rapidly correcting a printing characteristic of a printhead, a printhead whose printing characteristic is corrected by the above apparatus, and a printing apparatus using the printhead. In the apparatus for correcting the printing characteristic of the printhead, n kinds of printing control signal patterns are used to a full line printhead, printing patterns are experimentally printed in response to the printing control signal patterns on a printing medium and a reference density distribution is generated from one of n kinds of the printing patterns printed. Then, one of the n kinds of printing control signal patterns is selected for each of a plurality of printing elements such that a density value on each pixel is equal or close to the reference density distribution. In this case, a similar selection is carried out on another reference density distribution generated on the basis of another one of the n kinds of printing patterns, and an optimum one of the n kinds of printing control signal patterns is determined as correction data.

    摘要: A method for manufacturing a liquid jet recording head comprises of the steps of calculating the difference between the distance B from the first heater on the element substrate to the cut face of the element substrate and the distance A from the first flow path groove on the ceiling plate to the abutment reference of the ceiling plate, measuring the amounts of deviation in the positional precisions in the state where the element substrates and the ceiling plates are actually positioned, working out a correction value from the distributional condition of such deviations, feeding back the correction value for determining the corrected amount of retraction. Then, after the abutment reference of the ceiling plate is allowed to abut upon the cut face of the element substrate by means of a push jig, retraction is performed by moving the ceiling plate by means of a retraction jig in the reverse direction with respect to the element substrate, hence positioning the ceiling plate and the element substrate. With the method thus arranged, it is made possible to perform positioning in a higher precision at lower costs with a shorter tact time, thus manufacturing a highly precise and highly reliable liquid jet recording head.
