Effect of various ink types on naturalness perception of 2.5D prints

Abstract

Naturalness perception of 2.5D prints is content dependent and varies depending on the level of elevation used for reproduction. Moreover, various factors can influence the naturalness perception of 2.5D prints such as ink types, viewing angle, and illumination, to name a few. In this work, we focus on the effect of various ink types on the nat- uralness perception of 2.5D prints of wood images fabricated at 0.5 mm elevation. We found that the naturalness perception of 2.5D prints is influenced by the type of ink used. In particular, we found that 2.5D prints of wood images with matt inks were perceived by observers as more natural than with glossy inks. There were differences between the observers based on their level of expertise. The acquired findings can help to reproduce wooden content to be perceived as natural by using a specific type of ink.
