Lever-ATR FT-IR for Noninvasive Detection of Inkjet Ink in Printing Paper

The matched inkjet ink and alternatives in printing paper by Hp,Canon and Epson were determined by attenuated total reflectance of FTIR.According to the characteristic absorption of infrared spectrum,three kinds inkjet ink were distinguished and identified.The method is rapid,accurate and nondestructive.It provides a new method for the detection of inkjet ink.
