Braille is made by applying a special varnish on the areas that you want to enhance, on the label already printed.
What is it for?
To print the Braille alphabet and also to enhance parts of the label.
Value that gives to the label
The braille, being a varnish, gives a texture to the highlighted area different from the rest of the label, creating a glossy effect with a 3D sensation and brightness. In addition, it can be dyed, giving a greater effect.
