Rapid analysis of the quality of the recording coating on ink jet printing in preparation.
Preparation of the recording coating on the ink jet printing (RC-IJP) is proposed. The microstructure of RC-IJP was analyzed by scanning electron microscopy and atomic force microscope. The surface infiltration process of RC-IJP was studied. Fourier transform near-infrared (FT-NIR) spectra showed the combination and overtone vibrations information of the hydrogen-containing groups in RC-IJP structure. NIR spectra combined with partial least-squares methods were proposed for the noncontact analysis of the surface infiltration time and weight per unit area in RC-IJP. Forty-five samples were selected for the calibration sets of the surface infiltration time and weight per unit area, respectively. Spectral pretreatment method was used to develop robust calibration models. After the spectral pretreatment was optimized, the determination coefficient (R(2)) of the surface infiltration time and weight per unit area were 0.90 and 0.97, respectively. The analytical results showed that NIR spectra had significant potential for the analysis of the surface infiltration time and weight per unit area of RC-IJP.
