Abstract
A method of an embodiment of the invention is disclosed that determines calibration factors for a fluid-ejection mechanism that is capable of ejecting differently colored fluids onto media. The energy used to eject fluid for each of at least one of the fluid colors is adjusted based on the calibration factors, so that fluid drop ejections of the fluid colors yield fluid drop masses having a consistent ratio.
