Sažetak
The drying process of printing inks on the printing substrate is the final phase in the creative chain of a new product formation – the print. It is not only the expected mechanism of ink drying that influences the ink distribution on the substrate surface, but also the properties of the substrate itself. Many factors, like surface energy, roughness, sizing and porosity impact the ink distribution on both coated and uncoated papers. The scope of the study is to evaluate the applicability of several non destructive methods in the analysis of vertical and radial ink distribution on diverse Ink Jet prints. What is the extent and limits of Raman, UVR Raman, CLSM and FTIR PAS in the analysis of Ink Jet ink distribution in z-direction of the print? In the experiment both dye- and pigment-based Ink Jet inks were printed on different types of coated and uncoated papers. The results demonstrate the correlation between the Raman and CLSM methods for depth profiling. UVR Raman proved useful in the surface analysis of prints while FTIR PAS was useful for measurements at low depth in z-direction. The applied microscopic and spectroscopic methods provide us with a precise distinction between the upper homogeneous and the inside non-homogeneous ink layers. We also detected sporadic streams of deeply penetrated Ink Jet ink.
