Print Media

Siegwerk is one of the pioneers in publication rotogravure printing and is indispensable in this area of the printing industry. The company is rightly one of the world’s most important manufacturers. The reason for this strong market position lies, on the one hand, in long experience and, on the other, in the high quality of the printing inks that are used, for example, for catalogues or periodicals with large print runs. Siegwerk also supplies heatset offset inks for commercial printing, which are used for:

• Brochures
• Books
• Periodicals
• Leaflets and inserts

Sheetfed

Siegwerk offers a range of printing inks that covers all applications in conventional as well as in UV offset printing – from folding boxes for food or for luxury goods to food and non-food labels and commercial printing. The printing inks for food packaging are distinguished by extremely low migration levels and are very low-odor. Examples of the use of Siegwerk inks include:

• Packaging for spirits and perfumes
• Chocolate wrappers
• Beverage labels
• In-mould labels
• Brochures

The “Tempo” family of printing inks has been developed for conventional offset applications. It impresses with outstanding technical printing performance, durability and user-friendliness for short printing runs, face and reverse printing and in further processing. The product spectrum includes mineral-oil-free ink ranges and oil and water-based coatings for a large selection of applications in packaging and commercial printing.

All inks and coatings for UV applications are combined under the name “Sicura”. These printing inks contain no volatile organic compounds (VOC). They are highly reactive, robust and durable and can be used on a number of substrates such as paper, cardboard, aluminum and plastics. For food and cosmetics applications, Siegwerk offers specially developed ink and coating systems which are distinguished by extremely low migration tendencies and fulfill all legal requirements and regulations in every respect.

Liquid Food Packaging

Siegwerk is the point of contact when customized printing ink solutions for food packaging with liquid or pasty content are required. Excellent low migration level and fulfillment of very high demands on sensory properties are the top priority. However, it goes without saying that efficiency and highest quality printed packaging are still guaranteed. Siegwerk develops solutions for offset, rotogravure and flexographic printing in this sector. Printed materials include board and PE-coated board.

Among the possible products are:

• Milk cartons
• Juice cartons
• Cartons for ready meals, sauces and deserts

Digital Printing

A steadily growing fragmentation of print jobs, a shift of print processes toward the end of the value chain and the focus on make-on-demand solutions are continuously reducing the average run length. Aspirations to further minimize the costs of prepress and the desire to print on three-dimensional objects further increase the pressure on conventional technologies. Industrial inkjet printing can offer a solution for some of these challenges with pigment-based ink systems for drop-on-demand inkjet as the most promising technology currently available on the market – an area on which Siegwerk is particularly focused.

Our portfolio of UV and water-based inks for industrial inkjet is ideally suited for a wide range of substrates and applications including:

• Labels
• Coding & marking
• Blister and aluminum caps
• Direct printing on 3D objects
• Flexible packaging
• Corrugated board and boxes
• Paper-based substrates such as direct mail, tissues and napkins
• etc.

Moreover, different primers and overprint lacquers complement our  offering for digital printing further extending the application spectrum.

Whether WB or UV inkjet is the best technology depends on the application. WB Inkjet is particularly suitable for thin or porous substrates and is predestined for applications with high demands on product safety and conformity, like e.g. flexible packaging or corrugated board. UV Inkjet is in turn the perfect solution for thicker substrates with high requirements on brilliance, scratch and abrasion resistance, like e.g. for labels or direct-to-object printing. Both technologies enable a customization of ink and film properties to meet the end application – obviously without compromising on product quality and safety.

For Siegwerk, product safety and conformity are and remain the most important aspects of ink development. To ensure the highest level of quality, used ingredients not only follow diligent raw material introduction processes, but also are measured and evaluated by our experts. Especially in the pharmaceutical and food industry, it is extremely important to prevent contamination of packaged goods by components of the packaging material. For sensitive applications, Siegwerk offers special low migration inkjet inks – a valuable extension of our portfolio, particularly in the field of UV inkjet.

Over the years, Siegwerk has built up its own innovation center for digital printing solutions in Annemasse (France), where it is not only hosting various research, development and testing capacities, but also the most modern production facility for UV and WB inkjet inks.
