- The effect of washboarding occurs very often in the Corrugated board production process. This is a problem since it creates stripy print images in the flexographic post-print, which are more disturbing than colour deviations or smaller print defects. Much effort has been devoted to locating the problem and trying to minimize it. However, no studies have been made of whether changes in the liner surface could cause such stripy images. The worst conditions that a surface, which is supposed to be printed can be exposed to, are friction, heat, pressure and moisture at one and the same time. Exactly these conditions prevail in the double baker of the corrugated board machine. Therefore, this study was set-up trying to simulate the conditions in the double baker in order to gather knowledge of which factor(s) influence and what to what magnitude. The topography of the sample Surfaces was measured and compared with the original, untreated surface. Furthermore, the treated and untreated samples were printed in the IGT-FI laboratory flexo-printer to gather knowledge about how the above factors influence the print quality. The print was finally evaluated with print density measurements.
