M&H Plastics, part of the RPC Group and a supplier of plastic packaging, has developed a method of printing Braille characters directly onto plastic packaging. A high-build varnish is used to print the Braille dots directly onto the product using accurate control measures to ensure the height of the Braille alphabet remains uniform throughout the packaging run.
Samples of the Braille printing have been analyzed by the Royal National Institute of Blind People and measured against the Marburg and RNIB standards. The RNIB has validated the samples stating that readability was found to be good as the 0.30 millimeters dot height is above average. This new technique complies with BS EN 15823 as an approved braille labeling system.
Braille printing directly onto the product also has significant benefits over labels that can be easily damaged or peel off. Although developed for Braille, this process can also be used in traditional screen printing allowing customers to highlight specific design features by using an embossed effect.
