A method for developing calibration curves and for calibrating a halftone imaging device to reproduce on an imaging medium gray scale values equal to input gray scale values entered in said imaging device. According to this method a calibration function representing a linear change in reproduced halftone dot size on said imaging medium as a function of input halftone dot size is developed by using the device to reproduce on an imaging medium at least two test input dot values representing two different % halftone dot sizes and determining a linear change between the input and the reproduced halftone dot sizes. The dot growth is used to predict dot changes for other % halftone dots and thus construct calibration curves which may be used to calibrate the imaging device.
