Efficiently mixing inks saves costs in print preparation, prevents standing times, and avoids waste. Correctly measuring the inks on the substrate provides certainty of consistently high print quality.

We offer you trainings on the subjects of mixing and measuring inks at the Grenchen branch. The maximum number of participants is twelve persons. The trainings can be thematically combined on the same day. A balanced blend of theory and practice ensures that both the understanding of the properties of inks and practical handling skills are deepened.


The basic principles segment is managed by our development department. Among other things, it answers the following questions:

What raw materials does a printing ink consist of? Which attributes are produced by which raw materials? What rules are there for handling inks in practice?



The theoretical principles of measuring and mixing inks are sensible for anyone who wants to not merely operate the buttons of an ink measuring device, but also wishes to understand what happens when an ink is measured. The goal is to familiarize you with the background of measuring and mixing inks, and get you to know it in detail.


The practice segment is implemented by our experts in the quality laboratory. Course participants practice mixing a specific ink tone as quickly as possible and with few corrections. Our experts show how to effectively use remainder inks, and what challenges there are when using remainder inks. After all, we take sustainability personally!

Explanations regarding non-use

We often receive inquiries about the absence of specific substances or substance groups in our products. We answer these types of inquiries by using a standardized format of the EuPIA (European Printing Ink Association). In these declarations of non-use, we provide information about which substances and substance groups are not constitutional components of our recipes. Some raw materials are excluded from use in printing inks from the outset, since they may, for example, not be used for printing inks according to the criteria of the EuPIA exclusion policy for printing inks, are subject to a prohibition or restriction according to the REACH regulation (regulation (EU) no. 1907/2006, link to EUR-Lex) or are on the SVHC candidate list of the ECHA.

Most of the explanations concerning non-use that are provided here are generally valid for all Rotoflex products and provide reliable information about most of the questions in this field.

Key words:

Non-use of: Fanal pigments, bisphenoles, bisphenol A, phthalates, allergenic substances (EU-VO 1169/2011, appendix II), benzol, conflicting raw materials, latex, natural rubber, mineral oil, PFC, perfluorinated chemicals, PG 50, Pigment Green 50, GMO, genetically modified organisms, animal materials, PBT substances, vPvB substances, ozone damaging substances

Other key words: Chlorine content in printing inks, California Proposition 65

Statement of Composition (SoC)

Rotoflex AG supports you in the product safety evaluation of your individual foods packaging. Printing inks may be one of several sources of potentially migrating substances. We therefore provide information about potentially migrating substances that are contained in printing inks in a Statement of Composition (SoC). The SoCs state the identity and concentration of these substances. The specific migration limits (SML) which apply to these substances according to the plastics regulation (EU) no. 10/2011 and Swiss Regulation SR 817.023.21 are listed. The SoCs of Rotoflex AG are written in compliance with the recommendations of the EuPIA (European Printing Ink Association) and are based on current legal conditions. The regulatory basis of the SoC within the European market is the general regulation (EC) no. 1935/2004 concerning materials and objects which are intended for coming into contact with foods. The regulation (EC) no. 1935/2004 requires that materials and objects which come into contact with foods are manufactured in such a manner that no components are transferred to foods in a quantity which is a hazard to health. Furthermore, unjustifiable changes to the composition of the foods are prevented. The organoleptic properties are not impaired. In order to determine the conformity of an individually printed food package, the print processing facility/refiner must newly calculate the quantities of the potentially migrating substances based on his actual consumption of the printing ink or varnish.

For a practical confirmation of conformity of his printed packaging, the print processor/refiner may have to have migration tests implemented. If a customer orders migration tests from an analysis laboratory, we will support this process at the customer's request. A confidentiality agreement is closed with the laboratory in question; communications take place directly with the laboratory, and all information that is required for the testing is provided.

Self-obligation to association specifications

An important aspect which determines our conformity work consists of the recommendations and voluntary agreements - that is, self-obligations of our industry; for example, to the standards of the EuPIA (European Printing Ink Association), such as the EuPIA-GMP. The EuPIA is the European Printing Ink Association, as whose member we work together with approximately 40 other internationally active printing ink manufacturers.

The EuPIA guidelines are developed by the members themselves and then, naturally, followed. We are proud that we have been able to participate in this association work since many years - from the beginning - and can share expert knowledge and develop guidelines there.

Self-obligation to requirements of end customers

Conformity work means not only fulfilling the relevant legal requirements and self-obligations of our industry; there are also requirements of Brand Owner brand-name articles, such as the Nestlé Guidance Note on Packaging Inks.

Safety data sheets

The Rotoflex safety data sheets contain important information on our printing inks; that is, information about hazardous ingredients, classification and labeling of the product according to the CLP regulation (regulation (EC) no. 1272/2008), information about hazards or recommended protection measures when handling the product, and the procedure in case of accidents. They also contain information about disposal or information on transport. Our customers receive safety data sheets as part of standard procedure. They are naturally also available to you on request. The provision of a safety data sheet is obligatory in the commercial/occupational sector. Furthermore, we feel responsible and engage ourselves to ensure that our products neither harm human health, nor impair the environment. Safety data sheets fulfill the important purpose of providing information as to how to handle our products largely without danger.

Components of printing inks and raw material selection

Every printing ink recipe always starts with the raw materials. An interdisciplinary expert team is responsible for selecting suitable raw materials for our printing inks. Every new raw material is thoroughly tested for its technical and regulatory suitability. This is based on current expert knowledge and decades of experience. For reasons of health, occupational and environmental protection, some raw materials are generally excluded from use in printing inks. For example, we do not use any raw materials that are not allowed to be used according to the EuPIA Exclusion Policy. Among other things, the process until a raw material is approved or rejected comprises the following steps:

1. Requesting a sample

Requesting a sample, including raw material documentation from the supplier consisting of the safety data sheet, technical data sheet and a confirmation of the fundamental suitability of the raw material for coming into contact with foods.

2. Technical testing

The raw material sample is subjected to technical testing in the laboratory. Among other things, this includes an evaluation of suitability. If the evaluation is positive, we prepare test production and start the approval process.

3. Regulatory testing

Definition of purity requirements depending on the raw material type and the concentration in which the raw material is later used in the printing ink formulations. We also procure all additionally required information, including the composition of the raw material insofar as it is relevant for use in food contact. Finally, the decision is made as to whether the raw material will be approved as a Rotoflex raw material.

4. Approval

If the raw material is approved, we assign a definite raw material number. This process supports us in staying true to our Rotoflex guidelines and respecting consumer protection as taking priority. We engage ourselves to ensure that only safe raw materials are used for our printing inks, and are then formulated into conforming recipes. Based on these recipes, printing inks are manufactured under GMP [Good Manufacturing Practice] conditions; finally, together with careful information of our customers, they contribute to ensuring that safe printed packaging is produced.


ISO 9001

The quality management system of Rotoflex AG includes development, production and sales of printing inks and varnishes, and fulfills the requirements of the DIN EN ISO 9001. Rotoflex AG was first certified in the year 2005 according to DIN EN ISO 9001. Since that time, external monitoring or recertification audits take place annually.



DIN EN 13432

Print products such as newspapers, cardboard and other packaging are normally not composted for ecological reasons. They return to the paper recycling cycle or are disposed of in waste incineration to harvest energy. The demand for compostable packaging therefore tended to be of subordinate significance in the past. However consumer demand for bioproducts is rising. This is also associated with an increase in demand for biopackaging. In 2011, Rotoflex AG therefore first decided to develop a GREEN-LINE series which is DIN EN 13432 certified, and therefore, suitable for compostable packaging. The biological activity of the microorganisms which ensure the breakdown of compostable materials is not disturbed by the printing inks of the GREEN-LINE series.


Rotoflex printing inks of the GREEN-LINE series can also be recognized by the «OK compost» identification with the Rotoflex license code S316.

As a manufacturer of Inks for packaging, consumer protection is a top priority for us. Raw materials whose toxicological safety is not definitively proven are unacceptable to us! We have committed to compliance with the EuPIA guidelines and the recommendations of “Good Manufacturing Practice (GMP)”. We also offer the greatest possible security when creating recipes for inks in combination with the raw material introduction process. This is based on central approval by the conformity department. The provision of product information, compliance with requirements and guidelines of brand manufacturers, close cooperation with our raw material suppliers and active association work show that we take responsibility for safe, conforming products, and impair neither human health nor the environment. Today and tomorrow.


Regulatory Requirements for Inks and Printed Food Packaging

Food packages are printed to inform consumers about the contents, ingredients and nutrient content in accordance with the regulations of the foods information regulations (regulation (EU) no. 1169/2011). Consumers naturally expect safe food packages. We are happy to produce them.

The path to a safe printing ink starts with the right selection of raw materials, leads to conforming recipes and processing according to Good Manufacturing Practice, and finishes with subsequent calculations, evaluations and tests. We steadily procure the required information for this.

Since inks are only part of a finished package, the Compliance department or working in conformity cannot be considered separately. This affects not only the printing ink manufacturer, but each member of the entire value creation chain, from raw material suppliers via printing ink manufacturers, print shops and food packers, to the individual end customers.

Within this supply chain, we jointly bear responsibility for the finished packaging, and each member is obligated to make their contribution. For example, printing ink manufacturers assume responsibility for their Inks. On the other hand, printers are responsible for the printed packaging. The transfer of substances from the packaging or print ink layers into packaged foods is a process which is nonetheless unavoidable. The industry jargon defines this process as "migration". Substance transfer is limited to limit parameters permitted by law, so that consumer health as specified by Article 3 of the general regulations (regulation (EU) no. 1935/2004) is definitely not placed at risk.

Since there is no EU-wide harmonized, specific community law regarding Inks for food packaging, we here at Rotoflex - as a European printing ink manufacturer - believe that it is not enough to fulfill statutory requirements. We therefore gladly obligate ourselves to fulfill the standards of the Europäischer Druckfarbenverband EuPIA (European Printing Ink Association). These standards and guidelines are developed by the member companies of the EuPIA and implemented in the form of voluntary self-obligation. There are also additional requirements for brand-name articles, such as those of the Nestlé Guidance Note on Packaging Inks.
