Near infrared spectra combined with partial least squares were proposed as a means of non-contact analysis of the adsorptive ink capacity of recording coating materials in ink jet printing. First, the recording coating materials were prepared based on nano silica pigments. 80 samples of the recording coating materials were selected to develop the calibration of adsorptive ink capacity against ink adsorption (g/m2). The model developed predicted samples in the validation set with r2 = 0.80 and SEP = 1.108, analytical results showed that near infrared spectra had significant potential for the adsorption of ink capacity on the recording coating. The influence of factors such as recording coating thickness, mass ratio silica: binder-polyvinyl alcohol and the solution concentration on the adsorptive ink capacity were studied. With the help of the near infrared spectra, the adsorptive ink capacity of a recording coating material can be rapidly controlled.
近红外光谱结合偏最小二乘法被提议作为一种对喷墨打印中记录涂层材料的吸附油墨容量进行非接触式分析的方法。首先，基于纳米二氧化硅颜料制备记录涂层材料。选择80个记录涂层材料样本以建立吸附油墨容量相对于油墨吸附量（g/m²）的校准模型。所建立的模型对验证集中的样本进行预测，r² = 0.80且SEP = 1.108，分析结果表明近红外光谱在记录涂层上对油墨容量的吸附方面具有显著潜力。研究了记录涂层厚度、二氧化硅与粘合剂 - 聚乙烯醇的质量比以及溶液浓度等因素对吸附油墨容量的影响。借助近红外光谱，可以快速控制记录涂层材料的吸附油墨容量。
