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 entirely in private hands 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 radiation curing has been the special focus
of our research and development activities. Today we
are among the leading manufacturers of radiation
curable printing inks and lacquers worldwide 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 and therefore
we offer not only high-quality products but also a
comprehensive advisory service. For all questions concerning
the 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. In addition to our
range of standard products we will also develop in
cooperation with our customers individual solutions
for special requirements or new applications.

Monopigmented
UV Ink Mixing Systems
for Offset Printing/Letterpress
Short response times and production pressure are more
and more a part of the daily routine in the graphic
industry. Increasing quality demands and ever more
unusual customer requests have to be realized at the
press. A consequence of this fact has to be the consideration
of how special colour shades can be purchased
faster and less expensively. The answer is to have an
in house ink mixing station with monopigmented ink
systems.
By being able to rapidly mix precise colour shades in
the necessary quantity in house, the printing company
will increase flexibility. No delivery delays for spot inks,
always the right amount for one job and the reduction
of storage costs as well as lower disposal costs for
leftover inks are further advantages of an own mixing
station.
Mixing with Monopigmented Ink Mixing Systems
Following many years of positive experience using
monopigmented ink mixing systems for container
decoration, Zeller+Gmelin now also offers monopigmented
ink mixing systems with high colour strength
for the offset printing/letterpress sector.
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 whether PANTONE ® spot colours or other
colour systems have to be mixed, with our high-pigmented
ink mixing systems you will always get the best
possible result. Also special shades which are independent
from a reference-guide are optimal to match.
Colour-Management-Service
Our experienced team guarantees optimal support
and service covering all “ink mixing“ questions. From
assistance for specific colour-compositions up to the
planning and installation of complete ink mixing stations
– Zeller+Gmelin is your right partner. As well as the
direct support on your site colourimetrical-trainings at
Zeller+Gmelin are included as part of the service.
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
implies the right choice of printing inks and lacquer
systems have been used.
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 distinguish themselves because
of their low migration formulation and also because
of their very good printability.
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 characterized
by its very low odour.
• UVALUX ® U71 Series
Adhesion-optimized 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 centre which we have specially established
for the development of low migration printing inks,
for quality controls of our raw materials and for
internal assessment of test samples. It controls the
migration security of our inks by gas-chromatography
(GC-MS) and liquid-chromatography (LC-MS) with
mass-spectrogram.
Naturally we also send each of our low migration ink
series to independent analytical institutes for analysis
and evaluation.
With this double verification we offer maximum
possible product security to printers, brand owners
and consumers. Many analytical results prove that if
our low migration ink series are professionally handled
it is possible with them to meet or even clearly undercut
the legal 10ppb migration limit in migration tests
with 95% ethanol.
LC-MS
Electron Beam Curing
Offset Printing
ESALUX E4 Series
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 photoinitiators,
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
