We offer you a new generation of UV-curing printing ink systems for a wide range of applications in metal printing.
The ink series are very color-intensive and are characterized by outstanding flexibility. Naturally, they have all the fastness properties required for metal decorating. The series are suitable for printing on coated metal substrates in sheet-fed offset printing.
Applications
2-part cans and 3-part cans
Food cans
Technical containers
Crown caps and closures
Twist-off lid + 3-part aerosol cans
UVALUX U3
UV-curing premium ink series
The good ink transfer in the machine produces a high-gloss, flexible ink film with very good mechanical and chemical resistance. The ink enables excellent thermoforming results, which, however, depend on many influencing factors and not only on the printing ink. For example, the basecoat used has a strong effect on the thermoforming properties. The formability of UVALUX U3 inks is so good that they can in principle also be used on monoblock aerosol cans.
Properties
Excellent formability and thermoforming properties
Light fastness at least 6 (DIN 16525)
Hot sterilizable at 131 °C/30 min.
Resistant to solvent mixtures (DIN 16524)
Resistant to silver lacquers
High reactivity, therefore very good through-curing
Temperature resistant at least 180 °C/10 min.
Very high color intensity

Opaque white
Opaque white systems play an important role in metal decorating. We currently have 3 standard opaque white types in our program:
Unembellished white for mixing
violet tinted, for clear-coated sheet metal
blue tinted, for gold-painted sheet metal
METALCURE U30
UV-curing premium ink series
The ink enables excellent thermoforming results, but these depend on many influencing factors and not just the ink. For example, the basecoat used has a strong effect on the thermoforming properties. The formability of METALCURE U30 inks is so good that they can in principle also be used on monobloc aerosol cans.

UVALUX U37
UV-curing General-Line ink series
The UVALUX U37 series is a UV-curing ink series with deliberately reduced fastness properties that cannot be sterilized. It was specially developed for general line applications, e.g. for printing on technical packaging that is not sterilized. It is very color-intensive and is characterized by excellent flexibility. The good ink transfer in the machine produces a high-gloss, flexible ink film with very good mechanical resistance and excellent thermoforming properties.
Properties
Excellent formability and thermoforming properties
Contains colors with light fastness less than 6 (DIN 16525)
Not sterilizable
Resistant to solvent mixtures (DIN 16524)
Resistant to silver lacquers
High reactivity, therefore very good through-curing
Temperature resistant at least 180 °C/10 min.
Very high color intensity
Excellent printing behavior
Very good adhesion to painted substrates
Excellent scratch resistance
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!
No ozone formation
mercury-free technology
No critical UV-C radiation
Minimal heat input
Low energy requirement
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
