Abstract
A method for forming braille text on a recording medium, the braille text including cells with one or more dots in each cell, and at least one of the cells includes a plurality of dots therein, includes discharging a photocurable ink onto the recording medium and curing the discharged photocurable ink with light, thus forming a print layer on the recording medium, and discharging a photocurable ink onto the print layer and curing the discharged photocurable ink with light, thus forming one or more additional print layers on the print layer. The braille text has an intra-cell dot-to-dot spacing of about 0.38 mm or more and about 1.32 mm or less.
Claims13
A method for forming braille text on a recording medium, the braille text including a plurality of cells with one or more dots arranged in each cell, at least one of the plurality of cells including a plurality of dots arranged therein, the method comprising:
- discharging a photocurable ink onto the recording medium and curing the discharged photocurable ink with light to form a print layer on the recording medium;
- and
- discharging a photocurable ink onto the print layer and curing the discharged photocurable ink with light to form one or more additional print layers on the print layer;
- wherein
- the step of forming at least one of the print layer and the one or more additional print layers includes 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;
- and
- the first distance is greater than an intra-cell dot-to-dot spacing in the first direction.
An inkjet printer for forming braille text on a recording medium, the braille text including a plurality of cells with one or more dots arranged in each cell, at least one of the plurality of cells including a plurality of dots arranged therein, the inkjet printer comprising:
- an ink head including a plurality of nozzles arranged in line in a first direction that discharge a photocurable ink onto the recording medium;
- a conveyor that moves the ink head in a second direction that is perpendicular or substantially perpendicular to the first direction;
- a photoirradiator that outputs light to cure the photocurable ink onto the recording medium;
- a feeder that moves the recording medium in the first direction;
- and
- a controller configured or programmed to include a print controller that controls the ink head, the conveyor, the photoirradiator, and the feeder so as to form the braille text with the photocurable ink on the recording medium;
- wherein
- the print controller is configured or programmed to include:
- a feed amount setter that sets an amount by which the recording medium is fed per one iteration;
- a feed controller that controls the feeder so as to feed the recording medium in the first direction by the feed amount set by the feed amount setter per one iteration;
- a discharge controller that controls the ink head so as to discharge the photocurable ink onto the recording medium between a feed operation and another feed operation by the feeder;
- a moving controller that controls the conveyor so as to move the ink head in the second direction between a feed operation and another feed operation by the feeder;
- and
- an irradiation controller that controls the photoirradiator so as to output light onto the photocurable ink having been discharged onto the recording medium between a feed operation and another feed operation by the feeder;
- wherein
- the feed amount setter sets the feed amount to be greater than an intra-cell dot-to-dot spacing in the first direction.
