Near Infrared Spectroscopy (NIRs) has been applied for rapid and nondestructive paper measurement by replacing the current destructive method to the property of paper. Current standard methods for the property of paper were pH, moisture, breaking length, and folding endurance, which data were compared with spectrum of FT-NIR spectrometer. Various paper products such as copy, envelope, white, newspaper, as well as old paper produced around 1960~1980 were used as the sample. The correlation (R2) and standard error of prediction (SEP) results for breaking length, folding endurance, moisture and pH are R2=0.914, SEP=0.508, R2=0.926,SEP=0.281, R2=0.941, SEP=0.931, pH R2=0.949, SEP= −0.0631, respectively. This result show that NIRs can be applied to practical application for nondestructive analysis of paper records materials.
