Abstract
In a method for forming braille text on a recording medium, the braille text includes a plurality of cells with one or more dots included in each cell, and at least one of the cells includes a plurality of dots. The method includes discharging a photocurable ink onto the recording medium and curing with light the discharged photocurable ink, to form a print layer on the recording medium, and discharging a photocurable ink onto the print layer and curing with light the discharged photocurable ink, to form at least one additional print layer on the print layer. Resultant braille text is formed by the print layer and the at least one additional print layer, and the resultant braille text has an intra-cell dot-to-dot spacing of about 0.38 mm or more and about 1.32 mm or less.

A method for forming braille text on a recording medium, the braille text including a plurality of cells with one or more dots included in each cell, at least one of the cells including a plurality of dots included therein, the method comprising the steps of:
- discharging a photocurable ink onto the recording medium and curing with light the discharged photocurable ink, to form a print layer on the recording medium;
- and
- discharging a photocurable ink onto the print layer and curing with light the discharged photocurable ink, to form at least one additional print layer on the print layer;
- wherein
- resultant braille text is formed by the print layer and the at least one additional print layer, and the resultant braille text has an intra-cell dot-to-dot spacing of 0.38 mm or more and 1.32 mm or less, and
- the intra-cell dot-to-dot spacing is a spacing between an outline of a first dot and an outline of a second dot adjacent to the first dot.
