The method of screen process for representing natural color on vinyl by using of black, white and the three primary colors}

The present invention relates to a method of expressing three-dimensional effects and natural colors such as photographs by screen printing on vinyl products using only black, white, and three primary colors. Specifically, the halftone of the film is composed of a set of diamond-shaped pixels. In the step of making the film by attaching the film to the screen mesh, the mesh of the film and the mesh of the screen mesh are arranged to be matched with each other to produce the mixed color. The mixed color can be expressed as a combination of pixels of different colors. The present invention relates to a method of expressing natural colors on vinyl by screen printing using black, white, and three primary colors.

In general screen printing, screen mesh woven in nylon or stainless steel is fixed to a frame such as wood or aluminum, and a film is attached on the screen mesh to make a plate on the screen mesh by photochemical method to block the parts other than necessary images Open the screen plate to make a screen plate, and pour the printing ink onto the screen plate and press and move the inside surface of the screen with a spatula called a squeegee so that the ink passes through the mesh in the non-valve portion and is printed on the printed object under the plate. How to print out.

In general screen printing, since only 100% of a single color is expressed on a single surface, as many films and screen plates are needed as the number of chromaticities to be expressed. As described above, the conventional screen printing is a single color sequentially printed on the printed object, so that only the color distinction of the color and the color boundary is clear, and the natural color such as the color blurring that the color boundary naturally shifts is impossible. do.

Such a conventional screen printing method is a step of first producing a film using a document prepared in accordance with the print content. In this case, the film is required as many times as the number of prints separated by the chromaticity. And, all of the shape portion to be printed is composed of faces can express only a single color.

Next, the screen mesh is fixed to a frame made of wood or aluminum to form a frame. The quality of the screen mesh is determined by the number of grids per square centimeter between horizontal and vertical lines. If the number of grids is large, the resolution is increased to obtain a smooth image, and as the size is reduced, the image may be coarse. The frame of this step also takes as many chromaticities to express. The screen mesh here is not greatly influenced by the direction or shape of the grain. Since the portion of the film to be printed is composed of cotton, the resulting shape of the screen mesh becomes meaningless.

Next, after the photosensitive resin is applied to the screen mesh, the film prepared above is attached and exposed to light, thereby forming a wire part on the screen mesh to make a plate. In other words, the screen mesh is fixed to the frame, and then a photosensitive alcohol emulsion is applied to it to form a photoresist film and dried. Then, the film is attached to each plate and exposed to a strong light to the part that is received by the film and the part that is not received. The screen mesh is partitioned, with the boundary being partitioned. This is because the part where the film is to be printed and the part which is not to be printed is composed of cotton to form a clearly distinguished color and color. Therefore, since the alcohol emulsion of the lighted part is cured, if it is immediately washed with water or an organic solvent, the lighted part is not cured because it is not cured. This step takes about 20 minutes at approximately 20 ° C. Here, when the film is attached to the screen mesh, the portion to be printed and the portion not to be printed are attached to the screen mesh without regard to the grid shape and the direction of the grain of the screen mesh.

Next, as a screen printing step using each screen plate produced in the above step, the final finished product is printed by printing using each color on each screen plate. In this case, only the color division in which color and color are clearly distinguished is expressed, and natural colors such as color blur are impossible, and as many colors as desired are required.

Conventional screen printing including the above steps has a problem that can not be printed on vinyl, such as a three-dimensional effect and color blur, such as a picture, there is a problem that can not be used in a variety of fields because it produces a shape with a simple color classification However, there is a problem in that the efficiency is lowered since the film and the screen plate need to be as many as the chromaticity.

An object of the present invention is to be able to express the entire color in black, white and three primary colors and to display the three-dimensional and natural colors such as photographs by screen printing on the surface of the vinyl, such as air tube or air mat or beach ball for water leisure To this end, the dots of the screen printing film and the pixels of the wire portion of the screen plate are made of a myriad of diamond shapes and margins having different sizes and spacings, and screen printing is performed by using different colors. A method of expressing natural colors on vinyl by screen printing using black and white and three primary colors, in which the pixels of different colors are combined with the margins of the other side, so that the effect of natural color blur and the three-dimensional and natural colors such as photographs can be displayed on the vinyl by screen printing.

Hereinafter, the present invention will be described in detail step by step with reference to the accompanying drawings.

The present invention provides a film production step of producing a film consisting of only the surface of the color and the color boundary is clearly separated by the number of colors (hereinafter referred to as chromaticity) expressed in the manuscript; The screen mesh is fixed to a frame made of wood or aluminum to form a frame having the required number of chromaticities, and the photosensitive resin is applied to the screen mesh of each frame to dry. Then, each film is screened on the screen mesh. Attaching, irrespective of the direction of the grain, and making a screen plate (2) by forming light wires (1) on the screen mesh by light; In the screen printing method comprising a printing step of sequentially printing for each chromaticity by using each screen plate (2) to print in the shape of only the distinction between the color and the color;

The film production step is to decompose the printed document of the natural color expressed three-dimensional and color blur as shown in the photograph into five colors of black, white, and three primary colors (red, blue, yellow), and for each of the decomposition color For each film that will display each color, the part that will express a single color will be dense without the gap between diamond-like dots such as a grid of screen mesh, and the part that will show a mixed color such as color blur should be diamond-shaped. Constructing a single color film by dividing the dots in a single color from the single color to the thinning order and gradually increasing the size and spacing, and combining the single color film with two colors for color blur and mixed colors. Diamond-shaped dots forming the color blur of the film are placed in the space between the dots of the color blur of the single color film to be bonded thereto. Be configured to comprise the step of making the natural color blur of the film as the number of color separation in the same manner as the step of expressing is possible to produce a 2 saekyong film of a mixed color, and the one and;

In the engraving process, the screen meshes are aligned to each frame when the screen meshes are fixed to each frame, and the screen meshes are attached to each frame so that the shape and texture direction of the screen meshes are the same. And attaching the film to the screen mesh so that the diamond-like dots of the film are in the same position and direction because the film is made of diamond-like meshes, and the time, temperature, And engraving under conditions of humidity;

In the printing step, the diamond-like pixel 3 of the color blurring part of the one-color screen plate 2 for printing the color blurring part and the natural color is combined with another two-color screen plate 2 that expresses the color blurring or the natural color. Located in the margin 4 of the color blur portion, characterized in that it comprises the step of printing using a polyvinyl chloride (PVC) ink for primary color decomposition as ink.

According to the present invention including the above steps, the dot of the film for forming the screen plate 2 is made into a fine diamond shape, and the plate is made in accordance with the position and the direction of the lattice of the lattice of the film and the screen of the screen mesh in the step of plate making. The pixel 3 of each screen plate 2 as described above can be combined with each other on the printed object to express the effect of color blur, etc. You can do it.

In addition, the step of making in the present invention, the time, temperature and humidity should be accurate, which is the same as the usual case determined by the characteristics of the photosensitive resin.

In the present invention, all colors can be expressed in five colors of black, white, and three primary colors. When the white disc is a printed object, white color is excluded, and natural colors can be expressed in four colors. Various colors can be expressed. This allows the film to be composed of diamond-like dots and when the screen plate 2 is plated using the diamond-like dots, the diamond-like dots are formed of diamond-like pixels 3 to constitute the line portion 1. do.

That is, all colors can be expressed by a mixture of the four or five colors described above, and the effect of color blurring that naturally shifts from one color to another is realized by the combination of the pixels 3 of the present invention.

An example thereof will be described below with reference to FIGS. 1 to 4.

When red and yellow have a constant shape and there is a color blur including orange between them, orange is represented by a mixture of red and yellow, so that the film showing the red first color (5) has a diamond shape in the pure red part. The dots are very dense, and small red diamond-like dots are placed at regular intervals, ie at intervals, from the red to the orange to the yellow.

Also, the film showing the second yellow color 6 has a very dense diamond-like dot in the pure yellow portion, and a small diamond-like dot in the portion moving from yellow to orange to red. It is formed to be arranged at a portion, that is, spaced apart. Of course, here, the diamond-like halftone of the color-blurred portion of the film of the first color 5 is located in the space between the spaces of the color-blurred portion of the film of the second color 6, that is, the interval between the diamond-like dots. The diamond-like halftone of the color-blurring portion of the film of color 6 is located between the space portion of the color-blurring portion of the film of the first color 5, that is, between diamond-like halftone dots.

Partial details of the color blur of the screen plate 2 produced by the film formed of dots as described above are shown in Figs. 1 and 2, and an example printed thereby is shown in Fig. 4.

In detail, the first color 5, the second color 6, and the third color have a shape, and the first color 5 and the second color 6 have a color blurring portion that smoothly shifts to each other. For example, the screen plate 2 for printing the first color 5 is shown in FIG. 1, in which only the pure first color 5 is printed on the pixel 3 without the margin part 4. The portion that is densely and mixed with the second color 6 is arranged such that the pixels 3 are disposed toward the margin portion 4 gradually decreasing in size. In addition, the screen plate 2 for printing the second color 6 is shown in FIG. 2, where only the pure second color 6 is printed, and the pixels 3 are densely packed without the margin part 4. The portion mixed with the first color 5 is arranged such that the pixel 3 gradually becomes smaller toward the margin portion 4. Further, the pixel 3 of the color blur of the screen plate 2 of the first color 5 is located in the margin 4 of the color blur of the screen plate 2 of the second color 6, and the second color ( The pixel 3 of the color blur of the screen plate 2 of 6) is positioned at the margin 4 of the color blur of the screen plate 2 of the first color 5.

In addition, a screen plate 2 having a third color representing white or the like as a background color is shown in FIG. 3, which forms the wire line 1 as a whole. Of course, the screen plate 2 which expresses only a single color is unnecessary if the same color as that of the printed material.

Thus, a partial detailed view of the state of screen printing using the screen plate 2 manufactured as described above is shown in FIG. 4, where the base color of white is printed at the bottom and the first color 5 and the second color. (6) are printed on the left and right sides, respectively, and the color blur of the center portion where the first color (5) and the second color (6) naturally shifts is located in the margin part (4) of each pixel (3). While bringing the effect of mixing the color, the effect of the color blur by this is configured as the size of the pixel 3 gradually decreases, the effect is increased.

Of course, Figures 1 to 4 is only a simple embodiment, when using all five colors of black, white and three primary colors can represent a variety of colors.

As described above, the present invention makes it possible to express three-dimensional and realistic shapes such as photographs on the surface of vinyl such as water leisure and air tube or air mat and beach ball using black, white, and three primary colors. What was done to the tube is shown in FIG. 6.

The present invention as described above is made by forming the dots of the screen printing film and the pixel of the line portion of the screen plate composed of a myriad of diamond shapes and margins having different sizes and spacing, and screen printing in each color using the size and spacing These different dichroic pixels are combined with the margins on the other side, enabling natural color blurring effect and expressing three-dimensional and natural colors such as photographs, so that all colors can be expressed in black, white, and three primary colors. Natural colors can be displayed by screen printing on the surface of vinyl, such as air tube for water leisure or air mat or beach ball, and there is a wide range of applications throughout the industry.
