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.
提出了喷墨打印记录涂层（RC-IJP）的制备方法。通过扫描电子显微镜和原子力显微镜对 RC-IJP 的微观结构进行了分析。研究了 RC-IJP 的表面渗透过程。傅里叶变换近红外（FT-NIR）光谱显示了 RC-IJP 结构中含氢基团的组合和倍频振动信息。近红外光谱结合偏最小二乘法（PLS）方法被提出用于 RC-IJP 表面渗透时间和单位面积重量的非接触分析。分别为表面渗透时间和单位面积重量的校准集选择了四十五个样本。光谱预处理方法用于开发稳健的校准模型。在优化光谱预处理后，表面渗透时间和单位面积重量的决定系数（R（2））分别为 0.90 和 0.97。分析结果表明，近红外光谱在分析 RC-IJP 的表面渗透时间和单位面积重量方面具有显著的潜力。
