In order to illuminate the penetration of UV curable ink vehicle into press blankets, IR imaging system was used as a new technique. Cross sections of blanket were prepared for IR imaging. Spectra data for imaging were collected by moving the sample stage automatically. Acrylate and UV curable ink into a blanket could be characterized as a single wave-number map. In addition, each component in the UV curable ink could be characterized with a Principal Component Analysis (PCA). The penetration rate of low-viscosity acrylate was the same as that of UV curable ink with high viscosity. Moreover, the penetration rate of vehicle into the blanket was in order of acrylate monomer › acrylate oligomer › pre-polymer. This means that the penetration of the acrylate monomer affected that of UV curable ink into a blanket. In addition, the photo initiator transferred together with acrylate monomer in the blanket.
