PRINTER DEVICE FOR PRINTING TACTILE INFORMATION

摘要

The present invention relates to a printer device for printing information as a tactile relief structure on a medium, which on at least one side is coated with a polymerizable composition comprising a stationary phase component, polymerizable monomers and a radiation inducible polymerization initiator. The printer device comprises an addressable irradiation system, arranged to irradiate an addressed area of a polymerizable composition on medium located in said device. A radiation induced polymerization is induced in said addressed area to effect polymerization induced diffusion of polymerizable monomers towards said addressed area. Thus, a tactile relief structure develops in said composition on said medium.
