Abstract

Near-infrared (NIR) spectroscopy for analysis of residual solvent of printed inkjet ink on-site is newly developed. In the industry of water-based inkjet ink, heat drying process is performed after printing. However, residual solvents remain on the printed matter after the drying process, and these residual solvents affect ink-fixing properties. Gas-chromatography (GC) or gas-chromatography mass-spectrometry (GC/MS) is conventionally used for analyzing residual solvent of the printed matter. However, this method takes several days to obtain results. To analyze residual solvent on-site, NIR spectroscopy is developed, and the value can be quantitatively predicted on-site, and easily. Also, spatial resolution is improved with NIR compared with GC/MS measurement. Therefore, spatial distribution information can be obtained. Here, NIR spectroscopy for analyzing residual solvents in a short period of time, evaluating easily, and on-site is reported. Also, the relationship between residual solvent and fixing properties of the printed matter is studied in detail. The principle of measurement, and some application examples and relationships with fixing properties of the printed matter are reported in this paper.
