A method of controlling banknotes (2) having a first and a second print (O, T) executed at different stages, the method providing for acquiring the luminance values (Vb) of the pixels (P) of an image of a banknote (2); comparing each luminance value (Vb) with a respective luminance value acceptance range (I); and emitting a reject signal in the event at least one of the luminance values (Vb) is outside the respective acceptance range (I); a respective acceptance range (I) being determined statistically for each pixel (P) as a function of the luminance values (Vb) of the pixel (P) acquired from the banknotes (2). <IMAGE>
