The requirements which the consumable material “Braille varnish“ has to meet are very high. Several technical demands must be fulfilled – from excellent flow properties in nozzle applicators up to optimum drying – especially at high line speeds. A high technological competence and decades of experience in development, manufacture and application of UV-curing systems enabled Jowat SE to meet these very challenging demands on the product performance.
The possibilities of utilisation are limitless: Whether in mass production, for instance in pharmaceutical packaging where the individual specifications and lots change frequently, or in the marking of personalised medication packages with additional caution information, on the directions for use, on labels, or as advertising effect, for instance on visiting cards. This is a field where marketing departments can now implement completely new ideas, and profit from a newly gained flexibility.
The visual effect of the product is another major advantage of Jowat® PermaCoat® 689.89. The conventional expectation of a varnish is a glossy appearance. However, Jowat SE broke new ground by developing a matt, transparent Braille varnish - the writing or pictures underneath remain perfectly visible and readable. The question, after all, is: Who should be able to see the varnish? Ideally, no one. Blind people do not require visual effects like for instance gloss. People with good eyesight, however, often recognise glossy dots as negative, especially when they are positioned over small letters. This is another challenge successfully mastered by the formulators of the new Jowat® PermaCoat® Braille varnish.
