3D and UV printers enable to fabricate objects with variable shapes and colors. However, it is not clear how to print a desired visual texture. In this work, focusing on translucency, one of the visual texture, we introduce a technique to measure and fabricate it. In a general UV printing method, printing a white ink layer removes the translucency of a base material before printing color inks. On the other hand, our printing method utilizes the translucency of both the base material and UV inks to replicate desired translucency. A lookup table between ink layers on a material and its translucency is built by a few measurements with the Kubelka’s layer model and then finding the best combination for a measured translucency enables to replicate the measured translucency.
