Ricoh first to produce plant-based ink for packaging
25 February 2022
The new Ricoh plant-based ink is a spin-off from R&D Ricoh carried out with partner Olbrich in Germany.
This new ink is for the wide-format market, particularly in packaging. It has conspicuous advantages in this market.
- It is suitable for printing onto complex media such as corrugated cardboard, both white and brown
- It is durable: it has excellent “rub resistance” on packaging
- It is 100% biodegradable, and poses less issues than other inks do in recycling processes
- It dries quickly; there is no need for additional electricity to heat it or to shine UV light onto it to dry it. Ricoh describes it thus: “The oil penetrates porous substrates leaving the pigment near the surface. This reduces energy consumption and eliminates the need for the whole drying system.”
- The lack of biocides (normally added to keep inks from going off in storage) and of other nasties found in petroleum-based inks (for polymerization, for example) mean that at least some parts of food packaging can be printed in this way
- Owing both to its composition and the lack of heat required to dry it, it does not produce any noxious emissions during the printing process
