A calibration method for print engines is disclosed herein. In a preferred embodiment, the method comprised the steps of: providing a calibration chart ( 101 ) having a first array of reference colours thereon; printing a separate test sheet ( 102 ) at step ( 301 ) from a said print engine; the test sheet ( 102 ) having a second array of test colours thereon, each test colour corresponding to one reference colour of the first array; arranging both sheets ( 101, 102 ) together; scanning the sheets ( 101, 102 ) at step ( 302 ) to capture a digital image of the reference and test colours; analysing the colour characteristics at step ( 303 ) to obtain the colour difference between corresponding pairs of reference and test colours; and compensating any colour difference at step ( 304 ) by automatically adjusting the printer in accordance with the colour difference.
