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 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, 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 a dot diameter of about 1.2 mm or more and about 1.9 mm or less.
A method for forming braille text on a recording medium, the braille text including a plurality of dots, 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 ink dots of the photocurable ink upon landing have a diameter that is about one half or less of a dot diameter of the resultant braille text.
A method for forming braille text on a recording medium, the braille text including a plurality of dots, 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 ink dots of the photocurable ink upon landing have a diameter that is about one third or less of a dot diameter of the resultant braille text.
A method for forming a print on a recording medium, 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 first print layer on the recording medium;
- and
- discharging a photocurable ink onto the recording medium and curing with light the discharged photocurable ink, to form a second print layer over the first print layer;
- wherein
- the discharging and curing of the photocurable ink and an operation of moving the recording medium in a first direction are repeated a first number of iterations per a predetermined distance in the first direction, to form the first print layer;
- and
- the discharging and curing of the photocurable ink and an operation of moving the recording medium in the first direction are repeated a second number of iterations, different from the first number of iterations, per the predetermined distance in the first direction, to form the second print layer.
A method for forming a print on a recording medium, 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;
- the formation of at least one of the print layer and the at least one additional print layer comprises:
- a first step of discharging the photocurable ink onto a first area on the recording medium;
- a second step, after the first step, of moving the recording medium in a first direction;
- and
- a third step, after the second step, of discharging the photocurable ink onto a second area on the recording medium and further discharging the photocurable ink onto the first area, the second area being located in a second direction, which is opposite to the first direction, from the first area;
- wherein
- upon completion of the third step, a height of the first area is greater than a height of the second area.
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, 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 the 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
- the formation of at least one of the print layer and the at least one additional print layer comprises a step of repeating the discharging and curing of the photocurable ink and an operation of moving the recording medium in a first direction over a first distance;
- the first distance is greater than a dot diameter of resultant braille text.
