Producing Tactile Maps Using New Inkjet Technology: an Introduction

Abstract

Three common methods for producing tactile maps are mixed media, microcapsule paper and thermoform. This paper describes a new method for producing tactile diagrams using piezoelectric inkjet. To produce diagrams a photo-curing acrylic polymer ink is repeatedly printed onto a thermoplastic substrate and exposed to ultraviolet light which bonds the ink to the substrate and cures it solid. The speed and precision of the process means maps with fine, easily discriminated tactile features will be readily available to users. The new process will facilitate further psychological, psychophysical and cartographic research.
