All pharmaceutical products require variable data. Here, the ancillary marking is often no longer done using hot-embossing and thermal transfer printing. The demand for indelible variable data that are easily applied to all materials is also growing because of regulatory requirements and the security provided by laser marking. Tovenca creates ink and coating formulations that are specially matched to the laser system being used, thus enabling permanent laser-ablative or laser-reactive marking. The data is still perfectly legible even under extreme conditions and can withstand use in wet, rough, greasy or otherwise abrasive conditions. Laser marking also meets the demands of packaging development and marketing in that it offers an attractive and safe solution.
