The present invention relates to a method for displaying characters and figures by transparent printing, and more particularly, by using water-based ink on the upper surface of transparent printing paper on which various kinds of characters and figures are printed with colorless transparent ink. As a result, only the transparent printing portion of the aliphatic is allowed to remain in the original transparent state without the aqueous ink remaining on the ink so that only the transparent printing portion is exposed to the outside.

In the conventional method, by printing letters and figures on printing paper with irregularities, when rubbed using a pencil, the earthen dust of the pencil is attached to only the iron parts of the printed characters or figures. The print characters and figures are displayed to the outside. This is a method of expressing the necessary characters and figures by using the principle of cofficient friction between the pencil and the uneven printed characters on the paper.

However, there is a drawback that the character and figure presentation method using the friction coefficient principle as described above is limited to the use of printing paper. If printing paper is not a big problem, but if the surface is smooth art paper, etc. If you rub with a pencil to express uneven printed figures and characters, the friction coefficient between the pencil and the surface of art paper is smooth because the surface of the printing paper is smooth. There is a problem that it is difficult to express characters, such as because the soil dust is not properly arrived (때문에 着) because it becomes small. In other words, the display of characters and figures by pencil has a drawback that the use of the paper is restricted because the display is determined according to the smoothness of the printing paper.

In addition, in the case of expressing characters and figures using only a pencil, there is a disadvantage that color diversification is lacked because only black color is used.

The present invention has been developed at the end of a long research in order to solve the above-mentioned drawbacks of the prior art, and because of transparent printing, it is possible to express characters and figures even if a smooth surface is used, and also to use a pencil in uniform black color. Unlike only the coloring and display of characters and figures, it is possible to express characters and figures using various colors of water-based ink, so that the color can be diversified and the user can freely select the colors to be painted. In particular, when used in the kindergarten, elementary, middle and high school students' learning paper, the purpose is to provide an advantage that the learning effect can be doubled more than usual by attracting more interest.

The present invention is a means for achieving the above objects, the entire surface of the printing paper using a colorless ink only to print a transparent printing unit of 1 unit (unit), the surface of the printing paper on which the transparent printing portion is formed water-based ink By coloring with, only the non-pigmented aliphatic transparent printed portion is exposed to the outside.

In the above, the transparent printing part is a part where letters and figures are printed.

The above objects and other advantages will become more apparent from the description of the embodiments according to the accompanying drawings.

In addition, the following Example demonstrates an example of this invention, Comprising: This invention is not limited by this description.

Before describing the method for displaying characters and figures by transparent printing according to the present invention, the overall printing process will be described briefly as follows.

When the object is set, it is completed as a printed matter, that is, a book, through the process of editing process, typesetting process, making process, printing process, and bookbinding process.

In the printing process, printing is carried out with red, blue, ink, and yellow printing inks. When printing via all four colors, the printing process is generally called 4 unit printing, and the number of printing units can be arbitrarily adjusted. Do. The process of forming the transparent printing paper described for implementing the character and figure presentation method according to the present invention described below corresponds to the printing process of the above process, the embodiment is as follows.

EXAMPLE

1 and 2 show an example of a character display method, and FIG. 3 illustrates an example of a method of displaying a figure.

Transparent printing unit by printing characters and figures edited beforehand over the entire surface of printing paper 1 (1 ') previously cut to a predetermined size using unitless color only (3) (3 ') is formed. Thereafter, the printing paper 1 (1 ') on which the transparent printing unit 3 (3') is printed is handed over to the bookbinding process and bound in the desired book form.

In the drawings, the transparent printing part 3 (3 ') is displayed in bold black lines so as to be understood from the outside, but is actually transparent so that the dividing line between the character and the shadow body is not visually identified. In order to display the transparent printing portion 3 (3 ') of the printing paper 1 (1') formed in this way to the outside, the surface of the printing paper 1 (1 ') may be used by using an aqueous ink. When monochromatic or multicolored, the non-printing portions 5, 5 'on the printing paper 1, 1' are colored with aqueous ink to form the colored portions 7, 7 ', while transparent printing. In the portion 3 (3 '), the aqueous ink is not colored due to fattyness and remains in the original transparent printing state (FIGS. 1 to 3). This is due to the repulsion of water (aqueous ink) and oil (fat printing ink).

Therefore, since only the transparent printing portion 3 (3 ') is uncolored, only the transparent printing portion 3 (3') is exposed to the outside as illustrated in FIGS. 1 and 3b. Although the colored part 7 (7 ') is shown by the dot in the figure, it is in fact a fully colored state.

In the above, only an example of printing transparently on the entire surface of the printing paper 1 (1 ') by printing unit by 1 color using only colorless ink is used. 1 unit of colorless ink used in the present invention may be added to 4 units of unity to form 5 unit printing, wherein the transparent printing unit 3, 3 'is printed paper 1, 1'. It appears locally on the surface.

In addition, the colorless ink used in the present invention is a colorless transparent ink by removing only the color from a general dye ink, and the one having fattyness is the same as other inks.

In addition, although the printing paper 1 (1 ') used above may be any, more preferably Fuji is snow white paper and art paper, and foil is used for gravure paper and test paper. do.

As described above, the method of expressing characters and figures by transparent printing of the present invention has the advantage of being able to express characters and figures without being bound to paper, and especially in parallel with other colored inks, it is possible to make the transparent printing part appear locally. Since it is possible to express letters and figures, it is possible to print out only the part that contains an answer when it is applied to the subjective questionnaire, so that the answer remains by using water-based ink even if you do not see the answer sheet. This is immediately possible, so there is a good effect that it brings higher learning effects.

Claims (2)

The entire surface of the printing paper 1 (1 ') is printed on a transparent printing portion (3) (3') of 1 unit only by colorless ink, and the transparent printing portion (3) (3 ') is printed. By printing the surface of the printing paper (1) (1 ') on which is formed with water-based ink, by means of transparent printing such that only the aliphatic transparent printing portion (3) (3') is uncolored and exposed to the outside. How to display characters and figures. 2.
