EMBOSSING BRAILLE OF SEMI-HARDNESS SYNTHETIC RESIN FOR THE BLIND}

The present invention relates to a hard hard embossed embossed braille for the visually impaired, characterized in that the surface of the hemispherical body of the braille is embossed with an uneven surface to increase the frictional feel and increase the identification of the braille.

As shown in FIG. 1, the braille for the visually impaired expresses the braille 1 designated according to the position of the projection in units of three points and two rows, and is read by the tactile sense of the fingertip.

Such braille was constructed by braille or by pressing a thick paper with a manual or mechanical press means such as a perforated plate formed by braille.

Therefore, it is necessary to use thick paper which is expensive and bulky, which makes it difficult to handle and store the handling, and it is difficult to identify the braille and the paper surface by pressing the paper bump on the fingertips while reading the Braille at the fingertips many times. There was a problem.

In order to solve this problem, the prior art constituting the soft synthetic resin braille is known as Utility Model Registration No. 20-0151738 (registered April 20, 1999). As shown in Figure 2, the braille is formed of a soft synthetic resin hemispherical body (2) attached to the paper (p), and screen printing is possible, compared to the braille obtained by embossing the conventional paper is more convenient in plate making and printing It is easy to print in large quantities, and has a long life span of synthetic resin braille compared to braille of paper projections, and it is possible to use thin paper or resin film, thereby making the volume small.

However, the braille 1 made of the hemispheres 2 of the soft synthetic resin tends to be deformed as the soft synthetic hemispheres are pressed when the surface is slippery and the fingertips are pressed. Originally, Braille is a small one-by-one projection arranged at close intervals, so the touch of the fingertips for soft Braille is not clear, and the surface of the Braille is slippery, so the identification of the arrangement of Braille is not clear. The reading was so inconvenient.

The present invention is inconvenient to read the soft synthetic resin Braille in the braille formed of a synthetic resin hemisphere, the advantage of the simplicity of screen printing, screen printing and the selectivity of the useful materials of the braille printing paper and the durability of the braille as it is In order to rectify the phosphorus problem, the printing process of braille is carried out on paper by a screen printing method known as an ink containing a hard synthetic resin solution and a slight blowing agent in the ultraviolet printing ink so that the dots may be formed into hemispherical bodies due to the cohesive force of the synthetic resin solution. The ink is dried by passing through a simultaneous ultraviolet dryer. At this time, the surface of the hemispherical body of the braille is embossed with fine uneven surface by the foaming action contained in the ink, and the braille has a moderate hardness as a hard synthetic resin. Braille projections strongly support the fingertips, making the protruding feel of the fingertips clearer, and due to the rough surface of the hemispherical body, the identification of the arrangement of the protrusions is more evident than the conventional soft synthetic brailles. It is designed to be read.

In the braille of the synthetic hemispherical body, as shown in Fig. 3, the surface of the synthetic resin hemispherical body 3 is formed as a hard synthetic synthetic hemispherical body 3 embossed with braille 1 having an embossed surface 3a.

The braille 1 of the embossed hemispherical body 3 of the present invention, as shown in Figure 4, after screen-making (s) by the disk of the braille to be printed, then a hard plastic resin solution (B-MRC: trade name) Using the braille ink (4) containing 85% by weight, UV-curable ink (B-UV = B-type ultra violetray) and 5% by weight blowing agent (sodium bicarbonate), the doctor (p) 5), the braille protrusion 3 'is printed by a known screen printing method at a predetermined thickness. Since the ink of the printed braille protrusion 3 'is thin, it is formed into a hemispherical body 3 immediately on the surface of the paper by magnetic cohesion force, and the printed paper p is passed through the ultraviolet dryer 6 to the ultraviolet projection of 0.1-0.5 seconds. Dry instantaneously. At this time, the UV curable ink is embossed into the uneven surface 3a by the microbubble action of the simultaneous foaming agent which forms a polymer polymer by chemical reaction upon receiving ultraviolet rays and becomes a medium hard hemispherical body 3. The embossed braille 1 of the medium hard synthetic resin hemispherical body 3 is comprised.

The present invention is thus hardened immediately after passing through an ultraviolet lamp after printing, so you can read the braille at your fingertips. In addition, the present invention is composed of a hemispherical body (3) of hard plastic synthetic resin, the surface embossed braille (1) embossed with the uneven surface (3a), so lightly press the fingertips on the braille (1) medium hard hemispherical body (2) Is supported by the fingertips, the touch of the braille is clear, and the arrangement position of the braille is clearly identified by the rough uneven surface 2a of the hemispherical body 3. This makes it easier to read braille.

In addition, because the braille of the present invention can be screen-printed on thin paper or synthetic resin film, it is possible to print a large amount of braille books more efficiently, and because of its small volume, it is easy to handle, transport and store, and also constitutes Braille (1). The adhesion of the hemispherical body 3 of the medium-hard synthetic resin is strong, and the durability is good, and there is no peeling or falling of the braille even if it is used for a long time. In addition, when printed letters and braille of transparent ink overlap each other, a visually impaired person and a visually impaired person may read a book together. In addition, screen prints of heavy hard plastic resin with protruding braille and strokes can be screen-printed so that the visually impaired can read pictures or texts with touch.

The present invention is a heavy hard plastic hemispherical body composed of braille embossed with uneven surface, so the hard hard plastic hemispheres support the fingertips, so the small brailles formed on the paper can be clearly identified and the rough uneven surface of the hemispherical body Therefore, the identification of the arrangement positions of the hemispherical bodies is clear, and the reading of the braille by the tactile sense of the fingertip is clear. Therefore, the braille can be read more easily than the slippery braille of the conventional soft synthetic hemispherical body.

In addition, since the hemispherical body is strongly attached to the paper surface, the braille does not peel off or fall off due to the frictional force of the fingertip even after long use.

In addition, it is possible to screen print Braille on thin paper or synthetic film, etc., so that a large amount of Braille books can be easily and efficiently printed, and the volume and weight of Braille books are small and light, making them easier to handle, transport and store, etc. There are several effects.
