<p>A method and apparatus for generating colour printing data is described. The apparatus comprises a scanner (5, 12) for scanning an image (2) at more than one resolution and for storing a first set of output signals. First and second stores (9, 13) store first and second three dimensional modifying means defined by respective predetermined parameters, the stores (9, 13) being arranged to receive output signals from the scanner (5) and wherein, in use, the first set of output signals is modified by the first modifying means to generate a first set of n input signals, one for each of the printing colours. A monitor (15) is arranged to receive the n input signals, if necessary after conversion to a suitable format of m input signals, from the first modifying means to display the scanned image; and user-operable control means (16) is provided for adjusting the parameters stored in the first store (13), the arrangement of the first and second modifying means being such that in use at least when the parameters defined by the first modifying means have been finally set, corresponding parameters are set in the second modifying means.</p> |
