Printing inks oil selection is related to the desired nature of the varnish in the ink production. Petroleum-derived mineral oils and vegetable oils can be used in offset inks.
In this study, the behaviors of vegetable- and mineral oil-based inks on uncoated and coated paper surfaces were investigated in terms of printability. Solid tone test prints were done with offset printing of these inks. Print gloss of the printed samples was measured and a light fastness test was implemented on these samples in order to determine the resistance to fading. Absorption behavior and contact angles of the ink-printed films on the test papers were measured with the sessile water drop method depending on time, and surface energies were calculated.
On both paper types, linseed-soybean oil-based vegetable ink gave the highest brightness value. The lowest print gloss results on the paper were obtained from soybean oil-based inks. The lowest color change was recorded with mineral oil-based inks on gloss-coated papers. According to the ink-film-surface relation, when the contact angle is high, surface energy decreases and the absorbency of the ink-film is lower.
In this study, the behaviors of vegetable- and mineral oil-based inks on different paper surfaces, and the effect on the quality of printability as well as differences, have been evaluated, taking environmental and health factors into consideration.
印刷油墨的油类选择与油墨生产中所需清漆的性质相关。石油衍生的矿物油和植物油可用于胶印油墨。
在本研究中，从适印性方面研究了植物油基油墨和矿物油基油墨在未涂布纸和涂布纸表面的行为。用这些油墨进行胶印制作实地测试样张。测量印刷样品的印刷光泽度，并对这些样品进行耐光性测试以确定其耐褪色性。采用静滴法根据时间测量测试纸上油墨印刷薄膜的吸收行为和接触角，并计算表面能。
在两种纸张类型上，亚麻籽 - 大豆油基植物油墨的亮度值最高。纸张上最低的印刷光泽度结果是由大豆油基油墨获得的。在光泽涂布纸上，矿物油基油墨的颜色变化最小。根据油墨 - 薄膜 - 表面关系，当接触角较高时，表面能降低，油墨薄膜的吸收性较低。
在本研究中，考虑到环境和健康因素，评估了植物油基油墨和矿物油基油墨在不同纸张表面的行为，以及对适印性质量的影响和差异。
