Replication of geometrical features and surfaces are present at different production levels, from realization of moulds to final product. Geometrical features must be reproduced within specification limits, to ensure product functionality . In order to control the replication quality, mould and replica surfaces must be quantitatively analysed and compared. In the present work, reference simulated surfaces were considered and studied in order to evaluate the effectiveness and traceability of different analysis tools for replication quality control. Topographies were analysed simulating different surface mapping techniques, such as optical profilometry, scanning probe microscopy and scanning electron microscopy. Different strategies for surface analysis and comparison are proposed and discussed taking into account the instrument, the measuring range and the functionality of the surface
