Abstract
The present invention is a method determining where to add hardener in a multilayer coating pack on a web fed through a coating station. The process includes determining the frequency and amplitude of the process noise associated with the coating station, determining the growth factor as a function of frequency on the incline surface and repeating these two steps for each of the layers in the coating pack. The plurality of growth factors obtained as a function of frequency is converted into a plurality of wave amplification versus frequency. After the plurality of wave amplitudes versus frequency is determined, one then selects from this plurality the one which is below a predetermined value in order to reduce coating cross streaks.
