The Technical Advantages of Soy-Based Ink
Natural soybean oil was established as the best replacement to petroleum oil because of the following technical superiorities:
1. Soy ink used in lithographic printing processes has the ability to remain stable throughout the entire printing cycle. Thus, the press operator performs fewer adjustments, which enables him to attend more closely to the process, thus reducing the number of rejected copies.
2. Soybean oil allows the pigments to reach full vibrancy of colors in order to deliver high-quality print outcomes. This ability likewise entails additional cost-efficiency because of the reduced demand for ink application.
3. Printers have experienced more ease in changing dark colors to lighter colors, compared to the difficulty level posed by petroleum-based ink.
4. Another benefit of soy-based ink is its low-rub-off resistance as opposed to the prints produced by petroleum-based ink.
5. The de-inking of soy-based ink for purposes of pulp recovery results in less stress and damage to the paper fiber.
6. Wastes from soy-based ink could be reduced by recycling black ink with unused color inks, which also results in cost-efficiency.
7. The use of soy-based ink in industrial laser printers poses less detriment to the machine, since soy-ink responds rapidly to laser heat. That way, faster ink-absorption takes place on the paper, which results in a less likely chance of build-up on the machine’s plate.
8. The flow of soy ink adheres well to recycled paper with lesser tendency to concentrate or pick out on fibers.
