Ink colours print green

Sun Chemical: using renewable resource-based materials to green up ink formulation

It is what makes the printing process colourful, and now it can also be ink’s responsibility to make printing a lot greener.

Siegwerk chief executive Herbert Forker said what so many have been saying: “Sustainability will become more and more important for us all in the future.”


Forker explained Siegwerk’s definition of sustainable productiton of printing ink: “It is an integral part of any printed product. There is a careful selection of raw materials used in the formulation of inks. We maximise the use of renewable and recycled source materials wherever possible.”

Rudi Lenz, president and chief executive of Sun Chemical, explained Sun’s strategy: “We have adopted the use of materials
based on renewable resources, such as soy oil for news ink. We are increasing our use of renewable resource materials through our pioneering vegetable oil-based sheetfed inks. Some of our packaging inks for corrugated are made with natural starch. We are help-ing our customers to conserve energy with heat set inks.”

To reduce emissions of volatile organic compounds (VOCs), we have pioneered the development of water-based flexo inks.”
