The invention refers to a method of prediction the printability of an unprinted paper, paper board or board surface. The method comprises the steps of acquiring a topographic image of the surface; identifying depressions regions in the topographical image having a depression exceeding a predefined depression threshold; establishing a relationship between the relative amount of identified depressions regions and the areas of said regions calculating a value on the basis of said relationship; and using the value as measurement of the prediction of the printability of the paper, paper board or board surface. |
