We affixed adhesive tape (50-μm adhesive layer) over a 10-μm height gradation caused by black ink and applied pressure over it with a 2-kg roller. After leaving it at 23ºC for 24 hours, we made visual observations.

We affixed adhesive tape (50-μm adhesive layer) to a glass panel and applied pressure over it with a 2-kg roller. We then applied a sufficient amount of “artificial sebum solution (dyed red)” on the adhesive layer. After leaving it at 85ºC and 85% RH for 48 hours, we made visual observations.
