SIEGBURG, Germany—Siegwerk, a leading provider of printing inks for packaging applications and labels, is now offering an enhanced ink range for serviettes, kitchen towels and other tissue products—ColorTissue. This new ink system not only combines the best features of the company’s existing ready-to-use tissue inks, but also achieves high color intensity.

“The new ColorTissue series is the result of joint development work by our centers of excellence in Annemasse, France and Büdingen, Germany. It is an enhanced ready-to-use ink range for tissue applications that meets the highest market and regulatory standards,” Dirk Weißenfeldt, vice president paper & board and liquid food packaging at Siegwerk, explains. “The additional development of the new UNI T series of concentrates now enables us to offer our customers a modular system that allows them to mix printing inks in their own local mixing units.”
The ink series is ISEGA-certified and complies with current EU regulations, the Swiss Ordinance as well as with the requirements of various eco-certification bodies, like OK Compost.
In launching ColorTissue, Siegwerk is now offering an ink system featuring a high degree of color intensity that complies with both bleeding resistance (color fastness) requirements in accordance with EN 646, as well as with Primary Aromatic Amine (PAA) content limits as recommended by Germany’s Federal Institute for Risk Assessment (BfR). Furthermore, the new range is characterized by a reduced drying temperature, less stickiness and minimized odor pollution. ColorTissue features less than 1 percent volatile organic substances (VOC), and therefore conforms to the relevant EU and Swiss Ordinances. Other ink series strengths include long-term print stability and ease of cleaning.
The modular ColorTissue and UNI T system gives users the option of deciding between two alternatives. The highly concentrated UNI T BASE range can be mixed with a ColorTissue technical varnish to deliver maximum color strength flexibility and a complementary ink management capability. Siegwerk provides its customers with clear formulation guidelines, which must be complied to guarantee bleeding resistance in accordance with EN 646. This enables customers to mix printing inks for their tissue applications in their own local mixing units.
Siegwerk provides support in the form of a dedicated local service, which incorporates technical support, process optimization and the monitoring of operating costs based on the “total cost of ownership” principle. The focus of this modular system version is definitely on cost efficiency. Where customers require maximum handling flexibility as well as simple, direct applicability, they are recommended to choose a mixture of ColorTissue basic inks and ColorTissue extenders. This enables higher maximum color intensity to be achieved and guarantees EN 646-conformity of print results at any time. By adding ColorTissue extender and water, other adjustments to colors and print parameter settings can easily be performed on the ink mixture.
Production in Siegwerk dispensers is also no problem at all, the company reports. Both versions therefore have their specific advantages, meaning customers can select the most efficient solution that matches their specific needs and local circumstances
