To achieve a good transfer of coating / varnish, it is important that the correct pressure / guage is maintained. This can be achieved by using a compressible underlay. Compressible underlay plays a vital role in the coating units, because it absorbs the pressure between the relief of the coating blanket / plate and the impression cylinder and also reduces vibrations which are caused by imbalance bearing defects etc. Using the correct compressible underlay will greatly improve the final result
