Abstract:
A method for compensating for inoperative ejectors in a three-dimensional object printer has been developed. A printer generates half-tone data for a material for each layer of a three-dimensional object. The printer detects half-tone data that corresponds to an inoperative ejector of a printhead. The printer modifies the half-tone data by moving the half-tone values corresponding to the inoperative ejector to adjacent positions within the generated half-tone data in which a zero half-tone value is stored. The printer operates the printhead with reference to the modified half-tone data to print the three-dimensional object.
