The intersection of a printed document and stamp-seal determined in a sequence is one important method for confirming the authenticity and relative manufacturing time of document components. The spectral domain optical coherence tomography (OCT) system having a wavelength of 900 nm is used to examine several intersecting line samples made using laser and inkjet printers with oil-based and water-based stamp seals, thus obtaining 2D tomographic and 3D stereo images of the intersection line region to compare the imaging characteristics presented using two types of printers and determine the intersecting line sequence. This study investigated 120 intersecting line samples, including 30 groups made by laser printers and stamp seals and 30 groups obtained using inkjet printers and stamp seals. Each group of samples was repeated multiple times, and multiple areas were selected to repeat the test. The experimental results show that the contrast in the luminance distribution of the transmitted light reflected in the OCT images of the same intersecting line sequence formed by laser and inkjet printers differed. This can provide a reference for discriminating the intersection line sequence of printed documents and stamp seals.
