摘要 本文提出了一种对喷墨打印文档进行无损分析的新方法。我们的方法基于近红外区域 (NIR) 分子光谱和化学计量方法 - 主成分分析 (PCA) 的结合。这项工作的目的是准备光谱数据，用于分析 19 个样品之间的相互关系，这些样品由同一类型的办公用纸组成，仅用黑色墨水在其上完全打印黑色方块。使用海洋光学系统在两个光谱区域分别获得光谱，即泛音：1000-1600 nm 和组合波段：1600-2300 nm，以及纸基。实验结果证实了尽管数据集稀疏，该方法仍具有高可靠性。
Abstract This paper presents a novel approach in non-destructive analysis of inkjet-printed documents. Our method is based on the combination of molecular spectroscopy in the Near Infrared Region (NIR) and a chemometric method - principal component analysis (PCA). The aim of this work was to prepare spectral data for the analysis of the interrelationships between 19 samples consisting of the same type of office paper on which black squares were full printed in black ink only. The spectra were obtained separately using the Ocean Optics System in two spectral regions, i.e., overtones: 1000-1600 nm and combination bands: 1600-2300 nm, with the paper base. Experimental results confirmed the high reliability of the proposed approach despite the sparse dataset.
