JPS5810773A - Production for ruled paper of photosensitive copying machine - Google Patents

Abstract

PURPOSE:To obtain a ruled paper where unnecessary rules are not copied even if the ruled paper is copied as it is, by using a plane meshed film consisting of several very narrow wires. CONSTITUTION:Desired rules are preliminarily described with solid lines on a solid line film 6. A plane meshed film 7 consists of several very narrow wires as shown in magnified figure. Rules of the solid line film 6 are exposed through the plane meshed film 7 to obtain a plate material 8 for printing. Thus, good rules are always printed on the plate material 8.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to copy base paper used for photosensitive pot copying machines.
Although it is a turtle, especially using manuscript paper etc. f:, 8
It's about paper.

Conventional copy paper is not specified by 1% and is made of ordinary paper that is commonly used. Therefore,
This is fine if the paper is white, but if the paper has various ruled lines, the ruled paper will also be copied when the paper is copied as is, so not only will it be difficult to see the circled letters in the copy, but also if there are graphs or designs drawn on it. In some cases, it was completely useless, and there was the inconvenience of having to write each time on a separate blank sheet of paper and then copying it. In addition, copying machines have become rapidly popular in recent years, and the lack of original interrogation papers has resulted in the drawback that high-performance copying machines cannot be used effectively.

The present invention was developed in order to solve the above-mentioned drawbacks and inconveniences, and involves providing a flat screen film consisting of several extremely thin lines, and passing the chain flat screen film through a solid line film to a plate material. By creating a printing plate by exposing it to light, and printing on the desired paper using the printing plate, it is possible to obtain purchased paper that does not have extra ruled lines or the like even if it is copied as is. The purpose is a method for manufacturing lined paper for photosensitive copying machines.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

Fig. 11 shows a lined paper made by the manufacturing method of the present invention, and Fig. 2 shows a lined paper made by the conventional manufacturing method. The lined paper main body l obtained by the present invention has a thick outline l1I on the desired white paper 2.
3 is provided, and within the contour line 3, a vertically and horizontally movable fruit @4 is drawn. The lined paper main body 1 obtained by the conventional manufacturing method is similar to the lined paper of the present invention, in which a contour line 3 is provided on a white paper 2, and this contour line I! A dotted line 5, which can be vertically and horizontally, is drawn within 3. As described above, the feature of the ruled paper of the present invention is that the conventional ruled lines are dotted lines 5, whereas the ruled lines are drawn with solid lines 4. If you copy both of these lined papers using a copying machine, it will be lined @(*1lI
4, dotted line 5) are not copied at all. This printing method in which the ruled lines disappear upon copying is based on a conventionally known technique.

Fig. 3 shows the method for producing a printing plate according to the manufacturing method of the present invention. l! It is a line film.

On the solid line film 6, desired ruled lines are drawn in advance, and a solid line 4 is drawn as shown in this figure. 7 is a flat mesh film, which is a film consisting of several extremely thin lines; 8 is a plate material for printing;
The ruled lines of the solid line film 6 are exposed to light 9 through the printing plate.

Figures 4 to 6 are explanatory diagrams comparing the characteristics of the flat mesh film, which is the main part of the manufacturing method of the present invention, with the conventional manufacturing method.

FIG. 4(A) is a partially enlarged view of a conventional flat mesh film, and FIG. 4(B) is a partially enlarged view of the flat mesh film of the present invention. As is clear from this figure, the conventional flat mesh film 7 has a fine mesh pattern, but further analysis shows that the black dots 1O are arranged at equal intervals. Therefore, when trying to print desired ruled lines by superimposing the solid line film 6 on the flat mesh film 7, if the solid line film 6 partially covers the black circle dots 10 (gradient, if not at all, 0 and 0). There are two types of cases: (C), and there is no problem in case (C), but cases (A) and (B)
In this case, there is a drawback that the desired lines are not printed on the plate material 8.

In contrast, the lined paper produced by the method of the present invention has black lines @11 drawn at regular intervals on the flat mesh film 7, as shown in FIG. There are no such lines, and good ruled lines can always be printed on the plate material 8.This can be further explained with reference to Figs. 5 and 6. d In the case of conventional lined paper, as shown in FIG. Ruled line with point 15 (
If a flat mesh film 7 (c) with black dots 17 is used on a white background 16 as shown in (C), the ruled lines will be as shown in figure d. In any case, when such a flat mesh film 7 is used, the solid line film 6 is
The zero angle makes the mesh Ii5 non-uniform. That is, as shown in FIG. 6(A), when the solid line film 6 is superimposed on the flat mesh film 7 while turning the film 18411 once, the white background 14 and the black dots 15 within the dotted line 5 will be non-uniformly arranged. (A) m (B) as shown in Article 481 (a)
, and a good dotted line 5 cannot be obtained.
However, if printed, the dotted lines 5 may not be obtained.

In contrast, according to the flat mesh film 7 used in the manufacturing method of the present invention shown in FIG.
Even when obtaining the lined paper body 1 in black @@2 on a white background 14 using the flat wire film 7 (a), also in the case (b) when obtaining the lined paper body 1 in black @@2 on the white background 16, it is also possible to obtain the lined paper body 1 in black @@2 on the white background 16 by using the flat mesh film 7 (c) with the black color 22 on the white background 16. Part 1B white @@
When obtaining 23 lined paper bodies (even if it is a phrase, see Figure 6 (
As shown in (b), the solid line film 6 is placed at any angle [(1
8G'), a uniform and good solid line 4 can always be obtained. If lined paper is printed using the printing plate with solid lines 4, it is possible to obtain ruled lines that could not be obtained when using conventional dotted lines.

The present invention is configured as described above.

You can get ruled lines that cannot be obtained with conventional manufacturing methods (Idiot)
In addition, the visibility of the printed lined paper is high (the ruled lines are easy to see), and the spacing between the lines can be adjusted as needed, so you can easily prepare the screen by preparing the flat screen film in advance. , it is possible to easily print the desired lined paper, the manufacturing method is easy and convenient, and base paper for copying can be obtained at low cost, so it is a new paper that is excellent in all aspects such as performance, practicality, and economy. This can be said to be a method for manufacturing lined paper for photosensitive copying machines that can provide unique lined paper for copying. .
