BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a metal plate print and a manufacturing method, and more particularly, to a high precision metal plate print and a method for producing the digital form of a printed matter on a metal plate with a predetermined depth.

In general, a metal plate printed matter is manufactured by a casting method, a corrosion method, an etching method using a metal engraver (etching knife, laser, etc.), a sanding method, or the like.

The casting method is a method of making a mold called a casting in the same way as the text or image to be displayed, and using the casting sand to make a casting mold, and then melting a specific metal in the casting mold to finish it. At this time, since the uneven surface is the same as the uneven surface of the mold, the selection of the uneven surface and the convex surface is determined at the time of manufacture of the mold. Usually, the letter or image to be displayed is the convex surface.

However, this casting method is difficult to form very small letters such as newspaper type due to the lack of precision, and since the mold called casting must be produced every time in the same way as the printed contents, a considerable investment is required in the mold making, so the same product is mass produced. There is an economical only in the case of production, and in the case of producing a small amount of different productions, there is a problem that productivity and economical efficiency due to the production is significantly lowered because expensive mold production must be performed for each production.

The corrosion method develops a film in the form of a sound plate or a positive plate to display a character or image to be displayed, applies a photosensitive ink having acid resistance to a specific acid to a metal such as a copper plate, and then irradiates ultraviolet rays on the film of the negative plate or positive plate on the ink coating surface. After exposure to light, acid treatment and etching, the text or image to be displayed is formed. In this case, the appearing image is reversed depending on whether the film is a negative plate or a positive plate.

However, this corrosion method is a wet etching through the etching solution, so when the letters or images are produced on the metal plate to have a predetermined depth of concavities (문) etched phenomena are crushed or smeared phenomena are protruding form having irregularities It is impossible to form the letters on the metal plate. Therefore, in the case of using the corrosion method is a method of engraving the letters of the desired print in a concave groove (dotted dot) method using the chemical nicking technology, it is implemented by imprinting only to a depth of about micrometers hardly feel the protruding form.

Accordingly, the corrosion method has a problem in that the distinguishing power of a character or an image formed when a coloring operation using a specific color is not performed due to its aesthetic appearance is considerably inferior. In addition, there is a problem in that the depth of the irregularities is low, even small damage and scratches (scratch) of the surface due to the external impact is also damaged to the sentence pattern to reduce the preservation value as a print.

The method using a metal engraver (etching knife, laser, etc.) is to be displayed by etching or cutting the inside or the outside of the outline to a certain depth using the engraver in the same way as the outline of the character or image to be displayed on a metal plate of a certain standard. A letter or image is formed.

However, the method using the metal engraver can be etched or cut using an etching knife or a laser, so that only a certain size of the character or image to be produced is possible, and it is not possible to produce very small letters such as newspaper type. There is a difficult problem in nature. In addition, in the case of letters, one letter by letter must be worked on one by one, so the work speed is slow and there is a problem that productivity and economical efficiency are significantly reduced.

The sanding method forms a supporting hole with the same outline as the character or image to be displayed on the protective film, attaches it to the metal display plate to be displayed, and then sprays the gold steel to the exposed metal by using a pneumatically injector. The part protected by the protective film is left as it is, and the open part is intaglio. When the protective film is removed, a character or an image to be displayed is formed on the metal display panel.

However, the sanding method, like the corrosion method, deteriorates the preservation value of the printed matter due to the difficulty of identification because the text or image displayed on the metal plate is easily damaged by small damage and scratches on the surface due to external impact. There is a problem that the distinctiveness of a character or an image is remarkably degraded by aesthetic appearance.

As such, the etching method using a casting method and a metal engraver (etching knife, laser, etc.) is difficult to produce a precise sentence shape, and there is a problem that the productivity and economical efficiency of the manufacturing method are significantly lowered, and also the corrosion method and the sanding method (sending) method. The door pattern is easily damaged by small damage and scratches of the surface due to external impact, and also has a problem in that the recognition ability of a character or an image is significantly reduced due to aesthetic appearance.

Therefore, the present invention has been made in order to solve the above problems, by producing a digitized print of the print to have a concave-convexness of a predetermined depth (strong) to the damage caused by external impact and produced a very precise sentence pattern on the metal plate It is an object of the present invention to provide a high precision metal plate printed matter and a method of manufacturing the same.

Another object of the present invention is to provide a high precision metal plate print having a concave-convexness of a predetermined depth by using a multi-stage corrosion technique in a concave groove system that is realized at a micrometer depth in the case of a metal plate print using a conventional corrosion method and a manufacturing method thereof.

Other objects, features and advantages of the present invention will become apparent from the following detailed description of embodiments with reference to the accompanying drawings.

Referring to the accompanying drawings, a preferred embodiment of a high-precision metal sheet printed matter and a method of manufacturing the same according to the present invention will be described. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various different forms, only the embodiments to complete the disclosure of the present invention and complete the scope of the invention to those skilled in the art. It is provided to inform you.

1A and 1B are a cross-sectional view and a perspective view showing a structure of a high precision metal plate printed matter according to an embodiment of the present invention.

The digitized pattern of the printed matter is composed of a metal plate 40 formed of irregularities of a predetermined depth, and a protective film 70 coated on the metal plate to protect the metal plate on which the pattern is formed from external impact.

In addition, it is preferable to form the color 60 of another color in order to increase the identification power of the door pattern formed on the metal plate 40 on at least one of the concave or convex surface between the metal plate 40 and the protective film 70. At this time, as a method of forming a color of a different color on the surface of the metal plate 40 by using a chemical oxidation method through a solution to oxidize the surface of the metal plate 40 by discoloring the different arbitrary color according to the oxidation of the solution Use In addition, it may be painted using a colorant having any color on the surface of the second metal plate iron portion or the recess portion.

The metal plate 40 is any one of a copper plate, a stainless steel plate, and a zinc alloy plate, which are semi-permanently preservable metal plates, and the predetermined depth of the irregularities preferably has a depth of 0.05 mm to 1.2 mm.

When described in detail with reference to the accompanying drawings, a high-precision metal sheet printed matter and a manufacturing method according to the present invention configured as described above are as follows.

2 is a view showing the shape of the production film used for the production of high-precision metal plate prints according to an embodiment of the present invention, Figures 3 to 10 illustrate a manufacturing process of a high-precision metal plate prints according to an embodiment of the present invention It is a figure for following.

First, as shown in FIG. 2, first, at least two or more first and second production films 10 and 20 having different offset values are manufactured based on the same original sentence pattern as the printed matter 30 to be manufactured. For reference, the offset value refers to the width difference value B between the original sentence pattern and the sentence pattern printed on the transparent film as shown in FIG. 3. Therefore, when two production films are produced, the offset value of the second production film 20, which is the last, is preferably printed on the transparent film in the same manner as the zero value, that is, the original sentence pattern.

The production of the production film (10, 20) is edited in the form of an image having at least two offset values in consideration of the font size, depth, etc. to be imprinted by running a graphic editing program such as Adobe Illustrator, the original sentence pattern do. And by printing the edited image form on the transparent film, to produce at least two or more production film having a different offset value. At this time, the determination of the desired offset value, the film production quantity is determined by the judgment of a professional technician according to the form of the original sentence pattern, work equipment and process mentioned above. For reference, in the case of a small letter size print such as a general newspaper, it is preferable to produce two to three production films having different offset values as shown in FIG. 2 to increase depth and precision.

Here, using an example of two production films will be described as an example.

Then, as shown in Figure 4, through the washing operation to prepare a metal plate 40 of the desired size in a clean state to remove the foreign matter on the surface, the photosensitive agent 50 is applied to the upper surface of the metal plate 40 and dried. At this time, the metal plate 40 is preferably any one of copper plate, stainless steel plate, zinc alloy plate. In addition, since the photoresist 50 used is corroded to a depth of 0.05 mm to 1.2 mm in a metal plate corrosion process, it is preferable to use a liquid resist or a dry film having higher adhesion than glue.

Next, as shown in FIG. 5, first, the production film 10 outputted with the largest first offset value among the production films in which the sentence pattern is printed is pressed onto the metal plate 40 and the first production film 10 ) Irradiate a high intensity light beam on the upper part for a predetermined time. At this time, when the light beam is irradiated onto the metal plate 40 to which the first film 10 is attached, the transparent region of the first film 10 is transmitted so that the photosensitive agent 50 is in a rubbery state. As a result, the dark region of the first film 10 for production cannot be irradiated with light, and thus becomes a hardened state.

For reference, this is a case where a positive photosensitive agent is used, and in the case of a negative photosensitive agent, the region of the photosensitive agent 50 irradiated with light is cured.

On the other hand, the printed material 30 to be produced is formed in the region having an image form having an offset value in the production film 10 in order to produce the original sentence pattern is formed in black and the remaining area is formed transparent. Accordingly, in the photosensitive agent 50 applied to the upper surface of the metal plate 40, the region in the form of an image having an offset value is in a hardened state, and the remaining regions are not hardened, thereby becoming rubbery. In this case, in the case where the original text is to be engraved, the image form having an offset value in the production film 10 may be formed transparently and the remaining area may be black.

Subsequently, as shown in FIG. 6, the first production film 10 pressed onto the metal plate 40 is removed, and only the photosensitive agent 50 in a rubbery state is removed through development. In this case, the metal plate 40 may be heated to smoothly remove the photosensitive agent 50. Then, the upper surface of the exposed metal plate 40 is corroded by using an impregnation solution such as iron chloride on the upper part of the metal plate 40.

At this time, the impregnation liquid is made by hitting the upper portion of the metal plate 40 in a shower type through a nozzle-type device, and impregnated until the exposed metal plate 40 is corroded to a depth of 0.05 mm ~ 1.2 mm. desirable.

Subsequently, as shown in FIGS. 7A and 7B, by removing all of the photoresist 50 remaining on the upper portion of the metal plate 40, the upper surface of the metal plate 40 creates a first metal plate in which only a contour of a desired letter is protruded.

Next, as shown in FIG. 8, the photosensitive agent and other foreign substances on the surface of the first metal plate 40 generated in FIG. 7a are completely removed and maintained in a clean state, and then the upper surface of the first metal plate 40 is maintained. The photosensitive agent 50 is applied and dried.

In addition, as shown in FIG. 9, the second production film 20 having a smaller offset value than the first production film 10 of the printed image film is pressed onto the metal plate 40 and the second production film ( 20) A high intensity light beam is exposed to the upper surface for a predetermined time. At this time, the offset value of the second production film 20 is assumed to be 0 (zero), the sentence pattern printed on the second production film 20 is assumed to be the same as the original sentence.

On the other hand, when the light beam is irradiated onto the metal plate 40 to which the second film for production 20 is attached, the transparent region of the second film for production 20 transmits light so that the photosensitive agent 50 is in a gum state. In the dark region of the film 20 for producing the second film, light is not irradiated, and the cured state becomes. Accordingly, in the photosensitive agent 50 applied to the upper surface of the metal plate 40, the print sentence-shaped region is in a cured state, and the remaining regions are not cured and thus become rubbery.

Subsequently, as shown in FIG. 10, the second production film 20 pressed onto the metal plate 40 is removed, and only the photosensitive agent 50 in a rubbery state is removed through development. In this case, the metal plate 40 may be heated to smoothly remove the photosensitive agent 50. Then, the upper surface of the exposed metal plate 40 is corroded using an impregnation solution such as iron chloride on the metal plate 40.

At this time, it is preferable to impregnate the exposed metal plate 40 until it is corroded to a depth of 0.05mm ~ 1.2mm.

In addition, by removing all of the photoresist 50 remaining on the upper portion of the metal plate 40, the upper surface of the metal plate 40 generates a second metal plate in which a sentence pattern having the same shape as the desired sentence shape is imprinted. For reference, according to the work equipment and the process, a production film having a different offset value is required at the discretion of a professional technician, and when another production film remains, the photosensitive work is performed in the order of the process using the remaining production film. After the corrosion process, it is repeated until the final metal plate of the same shape as the original image is produced.

Subsequently, as shown in FIGS. 11A and 11B, the paint is painted using a colorant 60 having an arbitrary color on the surface of the iron plate of the metal plate according to the use of the product, or by sanding the surface of the iron plate of the metal plate. Make sure the metal plate color is displayed. For reference, the paint plate 60 may be painted or sanded on the metal plate recess. In addition, the protective film 70 is coated on the entire surface of the first metal plate 40 in order to prevent deterioration and discoloration of the metal plate and to prevent surface damage due to user carelessness and external impact.
