A method of digital printing is disclosed in which a digital image to be printed has at least one region having pixels comprising superpositioned layers of a first ink and a second ink. The method includes producing at least one sample print and calibrating misalignment of the superpositioned layers at a plurality of calibration locations on the sample print. The resultant misalignment data is provided to a morphing program to pre-deform the digital image to provide a modified digital image which compensates for misalignment during printing. The image is then printed using the modified digital image. An apparatus and a machinereadable storage medium comprising instructions executable by a processor are also disclosed.
