ABSTRACT:
The invention aims to optimize a given parameter of a process of coating a support with a liquid composition. The device comprises: a) means (9, 10) for varying the parameter according to a predetermined profile; b) first detection means (11) for producing a first density profile for the support (6) across the width of the support, as the parameter varies; c) second detection means (13) for producing a second density profile for the support (6) parallel to the longitudinal axis, as the parameter varies; and d) means (15, 10) for determining a range of values for the said parameter for which the first and second profiles are satisfactory.
