A method for determining ink receptivity on surfaces is disclosed. The method may be used to predictably and reliably screen suitable substrate coating compositions (and/or substrates) or alternately suitable ink compositions in printing applications. The method relies on determining the response of a surface to ink(s) in terms of the force needed to immerse and remove a sample of the surface from an ink. Preferably, the force is expressed in terms of a contact angle of the ink with respect to the surface. By adjusting the composition of the substrate coating composition (and/or substrate) or of the ink to result in the inks behaving in a similar fashion to the coated or uncoated substrate, predictable printed image characteristics may be obtained relating to such propreties as image density and definition.
