ARTICLE ANNOTATION

quote
In this study, scanning electron microscopy (SEM) with an energy-dispersive analyzer was used to examine the microgeometry of the paper surface. This method allows obtaining microphotographs with magnifications ranging from 10× to 300,000×, as well as determining the quantitative and chemical composition of microinclusions. Four types of paper samples with different compositions were analyzed: recycled paper with a density of 135 g/m² and 180 g/m², eco-paper based on CaCO₃ with a density of 75 g/m², and offset paper with a density of 80 g/m². Using the JEOL JSM-IT200 scanning electron microscope, SEM images were obtained, where a finely focused electron beam scanned the sample surface, effectively 'painting' the sample point by point. As a result, the microstructure of each type of paper surface was visualized, and its elemental composition was determined. SEM images and energy-dispersive spectrometry results showed that carbon, oxygen, and calcium are present in different proportions in various types of paper, affecting their surface properties and print quality. The application of scanning electron microscopy with an energy-dispersive analyzer for rapid surface analysis of paper is a promising approach, as it enables the prediction of ink transfer onto the printed material surface and ensures stable print quality when reproducing fine details and image elements.
