Waterbased Inks

Some market sectors currently have lower interest a balanced sustainability approach to renewability – Focus is maximum renewability Sustainable development is a Long Term Trend

Siegwerk works to increase bio-renewable content in each ink component.

Biorenewable content of Ink

* Measurement of Bio renewable C Content currently ongoing according to ASTM6866

Discussion around definition of renewable content in the ink is maturing with adoption of ASTM 6866 becoming more widespread. This method measures renewable carbon content based on C14 measurement.

Printing and End Use Performance can be maintained whilst giving a step change in Renewable content Example : UniBIO extenders and TV for Cups segment

Ensuring the ink has a minimum impact at the end of life of the pacakge Siegwerk ensures that at the end of life of the product, the impact of the ink on the compost-ability of the package is minimised. Unibase and Uni T Concentrate series have been tested for their impact on compost-ability. Using selected colour indices with appropriate Technical Varnishes allows “OK compost” requirements to be fulfilled. Compost-ability

• Lab Proofer & Press synchronization gives highly accurate color

matches - shade is right first time!

Press Return Usage (Direct & Mathematical Returns)

Example of Reuse: Return Ink Management

13

• Ink is refreshed and reused directly as same color or converted to

similar color

• All corrections and return movements are recorded for traceability

* Data from customer projects

Press Return Usage (Bulk Returns)

Example Recycle: Return Ink Management

* Data from customer projects

14

• Careful control of color matching principles allows press returns to be

easily converted into other colors via the dispenser

• Traceability is maintained
