Eco printing

Vegetable ink


I found that the website below explained the different types of vegetable ink

Greenerprinter uses soy and other vegetable-based inks which are less harmful to the environment than their petroleum-based counterparts. Soy and vegetable products are used in ink for their oils, which act as the vehicle for the ink pigments.

"There are several types of vegetable-based printing inks, including
- linseed (Flax),
- tung (Chinawood)
- castor
- canola
- safflower

Soy is popular because it is a very stable material that exhibits excellent "wetting" properties which enhance its ability to carry solid pigments." 







After my research, it is clear that soy ink is becoming more popular, it also seems to product better prints. Even though it costs more, it goes further than petroleum based inks.

I also found this article useful in highlighting the difference.

Other interesting facts about soy inks


- Some printers, especially newspaper printers, have managed to achieve high quality with all colour soy inks except black.
Soy oils tend to be clearer than petroleum oils, so the colours can be brighter.
Soy inks tend to work well with recycled paper.
