Reach

The REACH (Registration, Evaluation, Authorisation, and Restriction of Chemicals) regulation is a European Union regulation designed to ensure the safe use of chemicals. It affects manufacturers, importers, and users of chemical substances, including those used in screen printing inks. When discussing the content of REACH in the context of screen printing ink, several key aspects should be considered:

1. Registration
  • Substance Identification: Manufacturers and importers must register the chemical substances used in screen printing inks with the European Chemicals Agency (ECHA).
  • Data Submission: Information about the chemical's properties, uses, and safe handling practices must be provided. This includes toxicological and ecotoxicological data.
2. Evaluation
  • Substance Evaluation: Authorities may conduct further evaluations if there are concerns about a substance's safety, potentially leading to additional data requests from the manufacturer.
3. Authorisation
  • Substances of Very High Concern (SVHCs): Certain hazardous substances may be added to the Candidate List of SVHCs. Companies must seek authorisation to use these substances in screen printing inks.
4. Restriction
  • Restrictions on Use: Certain chemicals may be restricted or banned in screen printing inks due to their harmful effects on health or the environment
  • Compliance: Manufacturers must ensure their products comply with any applicable restrictions, which may involve reformulating inks or finding alternative substances.

By adhering to REACH regulations, companies involved in the production and use of screen printing inks can ensure that their products are safe for users and the environment, while also maintaining compliance with European Union chemical safety standards.
