Zeller+Gmelin
Expertise in Printing Inks
For many decades the name of Zeller+Gmelin has stood
for the highest quality and customer-orientated solutions.
We are a medium-sized independent company
with subsidiaries and trading partners all over the
world. In close cooperation with our customers we
develop individual solutions for sophisticated tasks.
Zeller+Gmelin was founded in 1866 and since then has
been completely privately owned, giving the company
a high level of independence, flexibility and customer
focus. The head office is still located on the foundation
site in Eislingen between Ulm and Stuttgart, Germany.
Since 1970 the special focus of our research and development
activities has been on radiation curing, and
as a result we are today one of the leading worldwide
manufacturers of radiation curable printing inks and
lacquers in the application areas of commercials, packaging,
labels and metal decoration.
Being a technically oriented company it is our goal to
give optimal support to our customers, therefore we
offer not only high-quality products but also a comprehensive
advisory service. For all questions concerning
any printing process you will find a competent and
personal contact person with us.
To support our customers we have established a technical
service centre with practically experienced application
engineers. We are able to offer advice and assistance
with all questions related to printing technology
and for any other special requirements. We install, in
cooperation with our customers, tailor-made colourimetric
systems, ink mixing stations and offer training
for their employees.
With high-quality, sophisticated products and a flexible,
independent company structure Zeller+Gmelin today is
your competent partner for “printing inks”.
This brochure presents our range of standard products
for offset printing and letterpress.

Monopigmented
UV Ink Mixing Systems
for Offset Printing/Letterpress
Mixing with Monopigmented Ink Mixing Systems
Based on many years of successful experience using
monopigmented ink mixing systems for container
decoration, Zeller+Gmelin can offer monopigmented
ink mixing systems with high colour strength for the
offset printing/letterpress sector.
With your own ink mixing station using a monopigmented
ink system you can be more flexible and
independent and able to react faster to your customer
requests.
Advantages
• PANTONE ® shades are easier to match.
• Ink mixes have a higher colour strength and are
purer, because only the really necessary pigments
are used for the mixture.
• The higher colour-intensity makes printing with
reduced ink lay-down possible.
• Reduced dot gain in halftone printing.
• More flexibility when adjusting colour strength
for special shades.
• Less colour deviations between reference sample
and mixed ink under changing light sources
(metamerism).
• The colour-communication between ink manufacturer
and his customer will be easier and faster
by the usage of monopigmented ink mixing systems.
• Mixing recommendations are available for all
PANTONE ® mixed shades.
• Ink dispensing, mixing and measuring systems
with different expansion levels are available.
• Reduction of stock expenses.
• Lower disposal charges for leftover inks.
In our production plants we work with the same
monopigmented ink mixing systems. This guarantees a
fast and effective colour communication between ink
manufacturer and printer.
Regardless of whether PANTONE ® spot colours or
other colour systems have to be mixed, with our highpigmented
ink mixing systems you will always get
the best possible results. Additionally, custom shades
shades which are independent from a reference-guide
can be optimally matched.
Colour-Management-Service
Our experienced team guarantees full support and service
around the topic of “ink mixing“.
From assistance for specific colour-compositions up to the
planning and installation of complete ink mixing stations
– Zeller+Gmelin is your competent partner.
Colourimetric training at Zeller+Gmelin is offered as part
of the service, as well as direct on-site support.
Monopigmented base inks are available for all the following
ink series.

Low Migration
UV Printing Ink Systems
for Printing of
Food-Packaging
The production of legally compliant food-packaging
requires the correct printing ink and lacquer systems to
be selected.
Based on our latest developments Zeller+Gmelin presents
a new generation of low migration UV printing
inks for printing of food-packaging and labels. These
products are distinguished by their low migration composition
coupled with excellent printing characteristics.
All our low migration ink series are formulated in accordance
with the guidelines of the Nestlé Guidance
Note and Swiss regulation SR 817.023.21.
Migration Types
Migration by
Penetration
Migration from the printed
side of the substrate
to the unprinted side.
Migration by Contact
(Set-Off)
Migration from the printed
to the unprinted side
of the substrate in a stack
or reel (set-off).
UV Offset Printing/Letterpress
• UVALUX ® U41 Series
Low migration UV offset printing/letterpress
ink series for universal use on paper and films.
The series was specially developed for running
on high machine speeds and is also characterised
by its very low odour.
• UVALUX ® U71 Series
Adhesion-optimised low migration UV offset
ink series, especially for printing on critical film
substrates.
Migration by
Evaporation
Migration by evaporating
volatile substances
through heating (e.g.
cooking, baking).
Migration by
Distillation
Migration by steam-distillation
through cooking,
baking or strerilization.

UV Waterless Offset Printing
• TORACUR W71 Series
Low migration ink series for waterless offset printing
that is especially suitable for the production of labels
and packaging.
Electron Beam Curing Offset Printing
• ESALUX E4 Series
Electron beam curing (EB) offset printing inks for
printing on paper and films.
Analytical-Centre
At Zeller+Gmelin we have at our disposal our own analytical
facilities, which we established specifically for
the development of low migration printing inks, raw
material quality control and for the internal assessment
of test samples. We can assess the migration from our
printing inks by gas-chromatography (GC-MS) and liquid-chromatography
(LC-MS) with mass-spectrography.
Naturally we also send each of our low migration ink
series to independent analytical institutes for analysis
and evaluation.
With this double verification we can offer the maximum
possible product security to printers, brand owners
and consumers. Analytical results have consistently
proven that if our low migration ink series are professionally
handled it is possible with them to meet or
even clearly undercut the legal 10 ppb migration limit
in migration tests with 95% ethanol.
LC-MS
Electron Beam Curing
Offset Printing
ESALUX E4
With the ESALUX E4 ink series a new generation
of electron beam curing (EB) offset printing inks,
especially for the production of packaging materials
has been created.
The inks of the ESALUX E4 series are universally
suitable for a large variety of paper and film materials.
Essential advantages of the EB technology are an
unchanging drying performance, regardless of colour
shade, ink lay-down or substrate, a very low heat
transfer to the substrate and low energy consumption.
Inks of the ESALUX E4 series contain no photo-
initiators, they show excellent odour- and migration
properties and have been formulated for the application
of food-packaging and “odour-sensitive”
products.
Applications
• Food-packaging
• Labels
• Flexible packaging
• Folding boxes
Properties
• initiator-free
• high gloss and high scratch resistance
• good adhesion
• low odour
• highly reactive binding agent system
• very good printability
• suitable for overvarnishing and hot stamping
• no post-curing
• VOC-free

Highly Reactive
UV Offset Printing
UVALUX ® U48 HR
For some time now, new types of UV dryer technologies
are offered for sheetfed presses. These new dryer
technologies are using special types of UV lamps and
adapted reflectors. The aim is to reduce the required
lamp output and due to this also to reduce the energy
consumption as well as the CO 2 emissions.
However, for this new UV dryer technology it is also
necessary to have a new generation of highly reactive
UV inks.
The UVALUX ® U48 HR series stands for this new
generation of highly reactive inks for UV offset printing
and was specially developed for applications using the
new UV dryer systems.
UVALUX ® U48 HR inks are universally usable on a
large variety of paper- and film substrates.
Properties
• highly reactive
• very good ink transfer
• low dot gain
• optimised ink-water-balance
