介绍了一种喷墨打印记录涂料的制备方法。用扫描电镜分析了RC-IJP的微观结构。傅里叶变换近红外光谱（FT-NIR）显示了RC-IJP结构中含氢基团的组合和泛频振动信息。采用傅立叶变换近红外光谱（FT-NIR）结合偏最小二乘法（PLS）对RC-IJP中记录材料的光泽度、平滑度和单位面积重量（Gr）进行分析。选取45个样本分别作为光泽度、平滑度和Gr的校准集。采用光谱预处理方法建立了稳健的校正模型。优化光谱预处理后，光泽度、平滑度和Gr的决定系数（R（2））分别为0.86、0.94和0.98。光泽度、平滑度和Gr的预测均方根误差（RMSEP）分别为1.65、13.86、0.054。分析结果表明，PLS近红外光谱法可快速、准确地分析RC-IJP生产过程中的光泽度、平滑度和Gr。
The preparation and manufacture of the recording coating on ink jet printing (RC-IJP) was proposed. The microstructure of RC-IJP was analyzed by scanning electron microscopy. Fourier transform near infrared (FT-NIR) spectra showed the combination and overtone vibrations information of the hydrogen-containing groups in the RC-IJP structure. FT-NIR spectra combined with partial least squares (PLS) methods were proposed for the analysis of the glossiness degree, smoothness degree and weight per unit area of recording material (Gr) in RC-IJP. 45 samples were selected for the calibration sets of glossiness degree, smoothness degree and Gr respectively. A spectral pretreatment method was used to develop a robust calibration model. After optimizing the spectral pre-treatment, the determination coefficient (R(2)) of the glossiness degree, smoothness degree and Gr was 0.86, 0.94, and 0.98, respectively. Root mean square error of prediction (RMSEP) of the glossiness degree, smoothness degree and Gr was 1.65, 13.86, 0.054, respectively. The analytical results showed that NIR spectra using PLS had significant potential as a rapid and accurate method for the analysis of the glossiness degree, smoothness degree and Gr in the manufacture of RC-IJP.
