A method of curtain coating, the curtain being formed from at least one layer of coating solution having a composite density &rgr; (kgm ) and a total volumetric flow rate per unit curtain width Q (m s ), the curtain being allowed to free fall a distance h (m), at a velocity U (ms ), onto a continuously moving substrate having a velocity S (ms ) with an application angle of &thgr; between the horizontal and tangent to the substrate at the point of impingement, the dynamic surface tension at the rear of the falling curtain being &sgr; (mNm ), the aforementioned variable parameters being controlled so as to prevent recirculation.
