Architecture for the printing of braille dots using UV gel ink
Abstract:
An improved apparatus and method for forming images comprising Braille, raised print, regular print, or a combination is described. The architecture for the printing of Braille dots using marking material such as UV gel ink. The UV gel ink is deposited on a drum that has an array of closely packed raised features like mesas that are cup-shaped. The mesas on drum are filled with the UV gel ink and transferred to paper or another substrate. Partial curing can occur on the drum and the dots can be fully cured after transfer to the substrate. The mesas are shaped so that the dots take on a final shape consistent with usual Braille features.
