Non-Destructive Elemental Analysis of Raster Roller Damage Using X-ray Fluorescence Spectroscopy

Despite numerous methods to optimise their operation and parameters, anilox rolls are subject rapid wear during use due improper cleaning processes. Therefore, regular diagnosis is needed. In this study, X-ray fluorescence (XRF) analysis based on Fe Cr was used determine the elemental compositions of raster cylinder coatings. Due layered composition roll, where Cr2O3 coating applied iron core, evaluation roll surface can be detection damage. A portable XRF apparatus identify selected elements even at low concentrations <1%. work, it proved that a preliminary, method for assessing technical condition an cylinder. The technique safely in non-destructive chemical analyses rollers’ flexographic printing technology, information aids may routinely obtained, thus enabling high-quality printing. This pioneering study which spectroscopy successfully assessment.
