1. A method for correcting distortion in image printing, the method comprising:
receiving a digital image acquired from a printed image;
estimating, based on the digital image, a geometric distortion having a wave-shaped pattern of features formed in the printed image along both a first axis and a second axis, different from the first axis;
calculating one or more pixel locations that, when multiple dummy pixels are implanted along both the first axis and the second axis, compensate for the wave-shaped pattern of the estimated geometric distortion along both the first and second axes;
correcting the geometric distortion in a subsequent digital image to be printed, by implanting the dummy pixels at the one or more calculated pixel locations along the first and second axes in the subsequent digital image; and
printing the subsequent digital image having the corrected geometric distortion.
