Traditional quick-drying inks often cause problems when printing on recycled paper, especially when the amount of ink is low (or a small surface area). This is because light ink causes the ink to stay on the ink roller longer than when printing thick ink or large surfaces. When the ink is waiting to be deposited on the paper, the ink on the ink roller has a tendency to lose solvent and increase viscosity. This high viscosity will pull out the weak fibers in the recycled paper and affect the normal printing. Tip: Vegetable oil-based inks have a lower viscosity than high-solvent inks. They also have better roller stability than high-solvent inks, a feature that keeps the viscosity low throughout the printing process. This ink stability is reflected in the cost of slow printing, which means that it takes longer time in lithography. However, this is a reasonable transaction for achieving high-quality prints on recycled paper.
