This research is devoted to the development of a new characterization of the Lasertex roughness, from first and second generations, which respectively correspond to channels and to insulated sinks at the sheet surface. The best procedure for assessment of Lasertex roughness with conventional stylet roughnessmeters is defined and the limitations of classical parameters for measurements on sheets and rolls are set out. New parameters to characterize the bead and the crater of the elementary roughness pattern are proposed. A programme for a microcomputer coupled with a roughnessmeter is described; this programme allows a complete characterization of the roughness. Special routines are adapted for both generations and give complete information on sheets and on rolls. Some application examples are described. The aspect after painting is then approached. The investigation shows that the distinctness of image is practically not influenced by the microroughness of the sheet but by the waviness of the surface. Finally, a short chapter is devoted to the applications of this new characterization method to the detailed study of the roughness transfer at the skin-pass mill.
