Description

Printout of Braille for the blind and its printing method {BRAILLE PRINTED MATTER FOR BLIND PEOPLE AND PRINTING METHOD THEREOF}

The present invention relates to a printed matter of braille for the blind and a printing method thereof, and more particularly, a normal person having normal visual acuity can read the printed content irrespective of the braille printed on the to-be-printed object. The present invention relates to a printed copy of Braille for the visually impaired and a method of printing the same, by using tactile contact with braille for easier and more convenient use of braille.

Braille is a special code character that allows the visually impaired to read with their fingers. Such Braille is called Braille because it is convex protruding on the ground so that it can be read with the touch of a fingertip. It has a unique writing system without drawing a normal letter with a dotted line. Braille is a six-point braille that combines six large and small dots arranged in two rows up and down to represent letters and symbols. Currently, countries that write phonetic letters from around the world use them according to their national characters. The standard size of Braille is 0.7mm in height, 1.4mm in diameter, and 2.2mm in center spacing, according to the Americans with Disabilities Act (ADA).

In addition, Braille is a tool called 'Braille Board' (also known as Braille), which writes from right to left using an awl-like dot-pen in the dot space.

In other words, the braille consists of six columns of three vertical and three horizontal points, which are connected to form a syllable. Use the unique numbers of 1-2-3 points from the top left and 4-5-6 points from the top right, and these six points are divided into the stamped and unprinted states, respectively. Combining the states produces 64 (2 ⁶ = 64) points. The letter given meaning to this point is Braille. And none of these 64 dot shapes are used as spaces, and these spaces are used to float between words, as in the mute. If you use 63 dots except blanks, you can represent letters.

As a method of printing such braille, there is a press-fitting braille printing method for protruding by using a point pen as a sharp tool of braille punching on a braille plate formed on a braille plate using a mechanism called a braille plate on a paper having a mass of heavy paper or more.

However, the braille printing method of the press-fitting method has a high production cost and a lot of restrictions on the paper material or material.

A conventional method of printing another braille is a computerized braille printer printing method for outputting a printed matter using a computerized braille printer.

However, such a computer-based braille printer printing method requires the purchase of a separate equipment, and the costs of the point and production separately takes a factor of increasing the product cost, there is a disadvantage that can not be applied to a large number of prints.

Accordingly, there is a need for a method of printing braille for the visually impaired while improving the productivity of the visually impaired by adjusting the height of the braille while greatly reducing the production cost.

The present invention is to solve the above problems, an object of the present invention, by forming a specially etched coating surface using a special transparent UV ink on the hemispherical projection, the normal person having normal vision and the braille printed on the printed matter The printed contents can be read regardless, and the visually impaired person can easily read the printed characters or pictures on the printed object by using tactile contact with braille. It is to provide a printed Braille and a printing method thereof.

Another object of the present invention is that even if you print Braille on a general print, the printed content can be clearly displayed without any problems to the general public, so that the visually impaired and normal people can implement the same information in the same production economical It is to provide prints of Braille for the visually impaired and a method of printing.

Another object of the present invention is to produce a thick film plate, a print screen type, and by special etching treatment, mass production is possible, and the production cost is greatly reduced and at the same time, regardless of the type of material to be printed. To provide a printout of Braille for the visually impaired with excellent readability and its printing method.

The present invention is a printing method of the braille for the blind to achieve the above object, by using a computer to convert the normal characters into Braille and then to a screen printing film to match the braille form of the braille form to the surface of the object to be printed. And producing a screen printing plate on which the dots to be expressed in braille are formed in a thick film forming method on the printing film so as to adjust the height of the braille to be printed; and screening the produced screen printing plate. Placing a to-be-printed object to be printed in braille by means of a stencil printing method and printing it with a transparent UV ink, thereby generating a plurality of hemispherical protrusions with transparent UV ink on the surface of the to-be-printed object through the through hole formed in the printing plate; Forming a readable coating surface on the hemispherical protrusion through an etching process; An object to be printed matter was passed through a UV oven is characterized in that consisting of a step of drying to print braille moment.

Here, the transparent UV ink is 20-50% by weight of the acrylate oligomer, 10-50% by weight of the acrylate monomer, sieving pigment 5-25% by weight, 5-20% by weight of polyolefin, 5-30% by weight of photoinitiator, Others are preferably composed of a composition ratio of 0.1-10% by weight.

In addition, the extender pigment may be any one of barite, whistle, chalk, clay and gypsum among white pigments.

In addition, the photoinitiator is added to the UV resin, and absorbs energy from the ultraviolet lamp to start the polymerization reaction.

According to the printed matter and the printing method of the braille for the visually impaired according to the present invention described above, the recognition rate of the braille is improved due to the application of a special nickname treated surface, unlike the prior art, the difficulty of manufacturing and processing surface due to the hard material It solves the problem of separation, improves the recognition of the disabled and the universal concept of the general public, and it is suitable for processing a large amount of prints, but it has a significant effect that can significantly reduce the manufacturing cost.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings, in order that the present invention may be easily understood by those skilled in the art. .

1 is a flow chart showing a printing method of the braille for the blind according to the present invention, Figures 2 to 6 is a schematic process diagram showing each step showing the printing method of the braille for the blind according to the present invention, for convenience of description Let's explain.

As shown, the printing step of the braille for the visually impaired according to the present invention, by using a computer to convert the normal characters into Braille is a vocabulary program and then the screened to fit the surface of the to-be-printed braille form 20 Producing a film 10 for printing (S10), and for screens in the state that the dots to be expressed in Braille on the printing film 10 in a thick film making method to adjust the height of the braille to be printed in the through hole 32 Producing a printing plate 30 (S20), and the printed object 30 to be printed in Braille by the screen printing plate 30 by the screen printing method put a transparent UV ink under the printing plate 30 for the screen In step (40), the transparent UV ink is formed on the surface of the object to be printed 20 through the through hole 32 formed in the printing plate 30 (S30), and the etching process is performed on each hemispherical protrusion. Read through Step (S40) of forming the coating surface 41, and the step of drying the instant to pass through the to-be-printed object (20) (50) 50 to print the braille (S50).

Here, the transparent UV ink 40 is 20-50% by weight (most preferably an acrylate oligomer) so that after the drying, a transparent resin braille is formed so that the convex portion of the transparent hemispherical protrusion becomes larger (toward upward). 35% by weight), 10-50% by weight of the acrylate monomer (most preferably 30% by weight), 5-25% by weight of the extender pigment (most preferably 15% by weight), 5-20% by weight of polyolefin ( Most preferably 10% by weight), 5-30% by weight of photoinitiator (most preferably 9% by weight) and other composition ratios of 0.1-10% by weight.

Here, the extender pigment refers to an achromatic pigment blended with other pigments in order to increase the amount or dilute the concentration, and inorganic substances such as calcium carbonate and barium sulfate are frequently used. Among them, white pigments include barite, whiting, chalk, clay and gypsum.

The polyolefin is a generic term for a homopolymer or copolymer with hetero olefin obtained by polymerizing a chain hydrocarbon having one double bond such as ethylene, propylene, butene, etc. into a unit, and the convex portion of the transparent hemispherical protrusion is It gets bigger and goes up.

The photoinitiator is added to the UV resin, and serves to start the polymerization reaction by absorbing energy from the ultraviolet lamp. That is, the photoinitiator serves to initiate photopolymerization by applying energy required for photopolymerization of monomers, oligomers, and free groups in the transparent UV ink material to convert the materials into a polymer material after curing.

The screen printing method and the thick film making method of the braille printing method of the present invention are applied. The braille for the visually impaired is subject to the standards set by the Americans with Disabilities Act (ADA), but may vary in size depending on the type of material to be printed, such as wood, metal, glass, acrylic, and synthetic resin. However, it is preferable that the shape of the braille is a transparent hemispherical protrusion.

Thus, the braille 60 for the visually impaired of the present invention is printed on the to-be-printed object 20 through the following process. First, a personal computer or a computer such as a notebook includes a point-in-point program for converting general characters into braille. Therefore, when a character to be printed in Braille is selected, the screen printing film 10 is manufactured by matching the dotted area of the braille form to the size of the printing surface of the to-be-printed object 20.

In addition, in order to adjust the height of the braille to be printed on the printing film 10 to produce a screen printing plate 30 for the state that the dots to be expressed in braille in a thick film forming method formed in the through hole. The thick film forming method is a special printing technique for increasing the thickness of an image to be printed. The thick film forming method is to complete the plate making frame after raising the thickness of the layer to a certain height by applying an emulsion several times. The screen printing plate 30 thus completed is in a closed state except for points to be expressed in Braille, that is, through holes.

Subsequently, the printed plate 30 for screen printing on the screen printing plate 30 is placed under the screen printing plate 30 and printed with transparent UV ink 40 on the printing plate 30. A plurality of spaced hemispherical protrusions are formed on the surface of the to-be-printed object 20 through which the UV holes 32 are transparent. Thus, the special transparent UV ink 40 is 20-50% by weight of the acrylate oligomer, 10-50% by weight of the acrylate monomer, 5-25% by weight of the sieving pigment, 5-20% by weight of polyolefin, 5-30% by weight of photoinitiator, and other 0.1-10% by weight of the composition ratio, the composition ratio of the hemispherical protrusions or the degree of hardening or the material or printing conditions of the to-be-printed object 20, the ratio may vary. Of course.

Subsequently, on each of the above-mentioned hemispherical protrusions, a readability coating surface 41 (component such as a phosphor material or paint) is formed through an etching process.

Finally, the braid 60 in the solid state is formed by temporarily drying the UV-resistant UV light while passing through the UV-driving furnace 50 through which the hemispherical protrusions on which the readability coating surface 41 is applied are passed. Be sure to

In this way, the transparent hemispherical projections can be easily recognized by passing through the braille 60. Thus, a normal person with normal vision can read the printed content regardless of the braille printed on the to-be-printed object. By using the braille to touch the processed braille more easily and conveniently, it is possible to easily read the characters and pictures printed on the printed object.

While the invention has been shown and described with respect to the specific embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made without departing from the spirit and scope of the invention as defined by the appended claims. Anyone with it will know easily.
