Accordingly, the braille can be printed on various products with high productivity.

Description

METHOD FOR PRINTING BRAILLE OF USING ULTRA VIOLET PRINTING BACKGROUND OF THE INVENTION [0001]

An embodiment of the present invention relates to a method of printing a braille using UV printing.

Braille is a special sign that allows the visually impaired to read through the fingers without being able to recognize things correctly with their eyes. Braille embossed points on the ground so that it can be read with the tactile sense of the tip of the fingertip. Braille is a 6-point braille character, consisting of six large and small dots arranged vertically and horizontally, to represent letters and symbols. Today, the countries that use phonetic letters in different countries use this according to their national characters.

Such braille printing has been produced by pressing and punching in thick paper, such as an electronic plate or an electronic typewriter. However, in this case, it is troublesome to use only special paper, the manufacturing cost is high, and the productivity is low.

Korean Patent Registration No. 10-1226208 (Feb. 22, 2013)

An embodiment of the present invention is to provide a braille printing method which is easy to manufacture and can increase productivity.

The braille printing method according to the exemplary embodiment includes the steps of printing a point at which a braille is to be placed on the printing film based on the converted braille data in the transfer printer; Subjecting the printing film to heat treatment of the article; Printing braille with UV soft ink on the product target based on positional data on a point where the braille is located in a UV printer; Confirming whether or not the printed height of the braille has reached a preset height in the UV printer; And repeating printing with the UV soft ink at the position where the braille is printed in the UV printer when the predetermined height is not reached.

According to the embodiment of the present invention, by printing the braille using the UV printing technology, the braille can be printed on various products, the manufacturing cost can be reduced, and the productivity can be increased.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings. The following detailed description is provided to provide a comprehensive understanding of the methods, apparatus, and / or systems described herein. However, this is merely an example and the present invention is not limited thereto.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail. The following terms are defined in consideration of the functions of the present invention, and may be changed according to the intention or custom of the user, the operator, and the like. Therefore, the definition should be based on the contents throughout this specification. The terms used in the detailed description are intended only to describe embodiments of the invention and should in no way be limiting. Unless specifically stated otherwise, the singular form of a term includes plural forms of meaning. In this description, the expressions "comprising" or "comprising" are intended to indicate certain features, numbers, steps, operations, elements, parts or combinations thereof, Should not be construed to preclude the presence or possibility of other features, numbers, steps, operations, elements, portions or combinations thereof.

Also, the terms first, second, etc. may be used to describe various components, but the components should not be limited by the terms. The terms may be used for the purpose of distinguishing one component from another. For example, without departing from the scope of the present invention, the first component may be referred to as a second component, and similarly, the second component may also be referred to as a first component.

Also, directional terms such as "one side "," other side ", "upper "," lower ", and the like are used in connection with the orientation of the disclosed figures. Since the elements of the embodiments of the present invention can be positioned in various orientations, directional terms are used for illustrative purposes and not limitation.

1 is a flowchart illustrating a braille printing method according to an exemplary embodiment. In the illustrated flow chart, the method is described as being divided into a plurality of steps, but at least some of the steps may be performed in reverse order, combined with other steps, performed together, omitted, divided into detailed steps, One or more steps may be added and performed. Also, one or more steps not shown in the method according to the embodiment may be performed with the method.

Here, a case of printing Braille characters in a mobile phone case will be described as an embodiment. However, the present invention is not limited to this, and it goes without saying that the present invention can be applied to a case where braille is printed on various other products.

Referring to FIG. 1, a common character is converted into braille in a computing device (e.g., a notebook computer, a personal computer, a smart phone, a tablet, etc.), and is transmitted to the first printer (S 101). The computing device may be provided with a progressive program that converts common characters to braille. However, the present invention is not limited to this, and a grace period program may be installed in the first printer. When the object of the product to be printed includes a curved surface such as a mobile phone case or a three-dimensional shape, the first printer may be a 3D printer. Further, the first printer may be a transfer printer.

Next, based on the converted braille data, the first printer prints the point at which the braille is to be placed on the printing film (S103). At this time, the first printer may print the background in addition to the point at which the braille is located. Here, the background may include characters, pictures, characters, graphics, and the like.

Next, after the printing film is dried, the printing film is coated on a product subject (for example, a mobile phone case) (S 105). For example, a printing film can be heat-treated on a product. In addition, a product coated with a printing film can be subjected to alcohol cleaning.

Next, braille is printed on the target of the product coated with the printing film using the UV printer (i.e., the second printer) (S 107). That is, the UV printer can receive position data from the computing device at the point where the braille is located in the print film. Then, the UV printer can print UV soft ink at a position corresponding to the position data.

Next, the UV printer confirms whether the printed height of the braille reaches a predetermined height (S 109). If it is determined in step S 109 that the printed height of the braille has not reached the preset height, the UV printer repeatedly prints the UV soft ink at the point (S 111). Here, the braille can be printed so as to have a height of 0.7 mm and a diameter of 1.4 mm. Then, the center interval between the braille characters can be printed so as to be 2.2 mm.

If the printed height of the braille reaches the predetermined height as a result of the check in step S910, the UV printer ends the printing of the UV soft ink (S113). Next, the braille character is subjected to the gloss coating on the printed product object (S 115). Thereby, the braille can improve the aesthetics of the printed product object.

FIG. 2 shows a state in which a blind person reads a Braille character with his left hand in a mobile phone case in which braille is printed according to an embodiment of the present invention.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed exemplary embodiments, but, on the contrary, . Therefore, the scope of the present invention should not be limited to the above-described embodiments, but should be determined by equivalents to the appended claims, as well as the appended claims.
