The modern UV and UV-LED offset ink series for packaging
Offset and letterpress printing – Offset printing is the perfect complement to other printing technologies in packaging printing. Its flexibility thanks to the low-cost printing plates, short set-up times and high machine speeds make it the optimum printing technology for packaging printing. The offset printing inks from Zeller+Gmelin are at home on your printing press. All ink series are developed and designed for high printing speeds with the best printing performance.
Ever shorter delivery times require increased production efficiency. The fast start-up and curing properties of the UVALUX ink series for food (FCM) and non-food applications enable vivid and detailed print results with breathtaking brilliance thanks to their high color strength and surface gloss, even at higher production speeds.

Toracur LED W580
The stable UV LED ink series for waterless offset printing
Waterless offset printing is often used for the production of labels and packaging on various substrates. Special printing plates are used here, which differ significantly from water-based offset printing.
The waterless offset printing plates have an ink-repellent silicone layer on the surface, which has a low surface tension. The underlying layer is ink-receptive and therefore a printing component. As a result, dot gain is kept extremely low and there are no fluctuations throughout the printing process. These properties are enhanced by Toracur W580 and lead to a high quality print result. Toracur W580 can be easily cured with all types of UV, whether LED-UV, UV-Hg or H-UV.

Areas of application: Non-food packaging, non-food labels, mailings, forms/commercials
ESALUX E4
New generation of electron beam curing (ESH) offset printing inks for label and packaging printing
With the ESALUX E4 ink series, a new generation of electron beam curing (ESH) offset printing inks has been created especially for the production of packaging materials.
ESALUX E4 inks can be used universally on a wide range of paper and film materials. The main advantages of ESH technology are consistent drying performance, regardless of the color shade, layer thickness or substrate used, very low heating of the substrate and low energy consumption.
Inks in the ESALUX E4 series contain no photoinitiators, have excellent odor and migration properties and have been formulated for use on food packaging and odor-sensitive products.
Versatile substrate selection
Initiator free
High gloss and high scratch resistance
Low odor
Areas of application: Food packaging, labels, flexible packaging, folding cartons
Modern FCM technology
In line with stricter legal requirements for printing on food packaging
Ever stricter legal requirements are increasing the demands for the production of legally compliant food packaging. The right choice of ink and coating systems is therefore all the more important.
Based on current developments and the latest raw materials, Zeller+Gmelin presents you with the right solution. Modern FCM ink systems contain significantly fewer migratable substances. Together with the use of special networked initiators, Zeller+Gmelin has minimized the potential for migration. The molecular weight of the cross-linked photoinitiators (approx. 1000 Daltons) is several times higher than that of conventional photoinitiators (< 400 Daltons). They also contain polymerizable groups that participate in the curing process and are thus firmly integrated into the chemical structure of the printing ink film. These properties make the FCM systems from Zeller+Gmelin extremely safe!
Our FCM technology is more than just "low migration". It is characterized by its high-quality composition, coupled with the highest requirements and lowest migration behaviour, as well as excellent printing properties.

LED technology
As a specialist for radiation-curing printing ink systems of the highest quality, we also offer high-quality printing ink in the field of LED UV technology.
LED technology is particularly interesting for environmentally conscious companies that not only want to conserve resources but also protect the environment. LED technology offers an economic and ecological advantage.
LED technology has developed into a true alternative solution in the field of radiation curing! In principle, the polymerization process of an LED ink is identical to that of a UV system. The difference is that an LED system dries with a specific wavelength. The cross-linking reaction is therefore triggered by excitation in a very narrow wavelength range. Industrial LED systems can operate in a wavelength range from 365 nm to 405 nm. The most common systems are those that emit at 385 nm or 395 nm.
Environmentally friendly + sustainable
Our printing inks are highly reactive systems which, thanks to their formulation, do not require any kind of volatile raw materials. This makes our printing inks solvent-free and emission-free! LED technology also completely eliminates the need for mercury vapor lamps. This means that you no longer have any mercury in your production process and are therefore protecting the environment. By using a specific wavelength when using LED spotlights, no ozone is produced on the machine, the heat input is reduced to a minimum and no critical UV-C radiation is emitted. This makes our LED ink solutions a user and environmentally friendly system!

mercury-free technology
No critical UV-C radiation

Profitable + Powerful
LED lamps are ready for immediate use, eliminating standby and heat-up times. You can operate the lamps in "switch on-switch off" mode and thus clock your processes. In addition, LED units can be partially switched due to their design. This enables LEDs that are not required to be switched off outside the print area. LED lamps also have a much longer service life without any loss of power. This extends maintenance cycles many times over.

Analytics Center
Zeller+Gmelin has an in-house analytics center that was set up specifically for the development of low-migration inks, for raw material controls and for the internal testing of test samples.
We now also have the option of liquid chromatography with a high-resolution quadrupole time-of-flight mass spectrometer for even more precise and sensitive analyses. In addition, we always have our low-migration ink series tested and evaluated by independent analysis institutes. This double testing enables us to offer printers, packaging buyers and consumers the greatest possible product safety.
Numerous analyses have shown that when used properly with our low-migration ink series, the legal limit value of 10 ppb can not only be safely adhered to in migration tests with 95% ethanol, but can also be significantly undercut.

Mixing with Z-Base Colors
Based on years of positive experience with monopigmented color mixing systems, we offer a monopigmented color mixing system for all our color series.
We work with the same monopigmented color mixing systems in our production facilities. This ensures fast and effective color communication between the manufacturer and the print shop. Regardless of whether PANTONE® spot colors or other common mixing color systems need to be mixed, our highly pigmented color mixing systems always achieve the best possible result. Even fan-independent shades can be optimally adjusted.
Advantages
PANTONE® tones can be blended better
Color mixtures are more colorful and purer, as only the pigments actually required for a color mixture are used
the higher color intensity enables printing with low layer thicknesses
Reduced dot gain in halftone printing
Greater flexibility when setting the color intensity of spot colors
fewer color shifts when viewing the printed products under different light sources (metamerism)
Color communication between the color manufacturer and the customer is simpler and therefore faster thanks to the use of monopigmented mixing systems
Mixing recommendations are available for all PANTONE® shades
Color formulation, mixing and dosing systems are available in various expansion stages
Reduction of storage costs
Lower disposal costs for leftover paint
