摘要：A method for controlling the print density of individual heating elements of a

thermal print head array determines respective energy values for each heating elementin response to image pixel data to be printed, multiplies determined energy values by arespective predetermined correction factor for one or more respective heating elementsfor improving print density consistency between individual heating elements, and dithersadjusted energy values from the step of multiplying as a function of adjacent imagepixels.
