Quick-drying ink tips

Traditional fast-drying inks are ideally suited for front-side (or non-recycled) paper, but the same inks tend to cause problems when printed on recycled paper, especially when there is less ink (or a small area of ​​surface). 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, there is a tendency for the ink on the ink roller to lose solvent and increase the viscosity. This high viscosity will pull out weak fibers in the recycled paper, affecting the normal printing process.

Tip: Vegetable oil inks have lower viscosity than high solvent-based inks. They also have better ink roll stability than high solvent inks, which keeps them low in viscosity throughout the printing process. This ink stability is reflected in the cost of slow printing, which means that it takes longer in the reprint. However, this is a reasonable transaction for achieving high quality prints on recycled recycled paper.
