There is a need to improve the paper quality to facilitate writing since poor gliding of the pen or pencil tip can result in a disappointing tracing The aim of this study was to characterize the damage induced on paper by pens and pencils. A new optical metrology device was tested to investigate the paper surface topography following pen and pencil strokes on different types of paper applied with various pressures. Paper roughness and surface deformability were found to be key parameters in reaching the best compromise. 收起
