The Stability of Ink-Jet Prints

摘要

The stability of the printed area can be observed from two different and independent points of view: physical and optical; each of them is relevant for the final use of the print. In our study we observed the influence of substrate surface on the stability of ink-jet printing. For this purpose, we chose different samples of paper (varying in quality, grammage, composition, surface treatment). The analysis of paper surface (smoothness, roughness, porosity) was first done on unprinted paper with conventional PPS method and with modern CLSM method. Also the dynamics of water penetration was measured. All the paper samples were subjected to ink-jet priniting. The samples were exposed to heat resistance test according to the ISO-11798 standard. The mechanical stability of the prints, expressed as rub-off resistance, was measured before and after the heat resistance test. Two different methods were used: Quadrant and Pira Wallace. The obtained results represent a part of a larger study on the behavior of various types of masterless printing.
