Abstract:
A method, apparatus, and computer program for calibration of a printer having a printed head with multiple dies creates linearization tables that compensate for different drop weight uniformities printed by die-to-die boundaries. The linearization tables are provided to a calibration routine to create an actual linearization table for ink printed by a die-to-die boundary of the print head. The calibration routine creates an actual linearization table by determining a measurement related to drop weight uniformity when the die-to-die boundary of the print head prints the ink. Based on this measurement, a pre-built linearization table is selected for compensating output drop weight and for allowing printing with a substantially uniform drop weight across the die-to-die boundary of the print head.
