JPS6018948Y2 - Lined paper used with manuscript paper for photosensitive copying machines - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a lined paper used for manuscript paper, etc., and particularly to a lined paper used in conjunction with manuscript paper of a photosensitive copying machine such as a photocopy machine.

The lined paper that has been commonly used in the past is all printed with solid lines, so if you copy this using a photosensitive copying machine, the lines will be copied as is. Not only can this method not be used for copying graphs, figures, etc., it also has the disadvantage that the printed text may have darker lines than the written text, making the text difficult to read.

The present invention was devised to solve the above-mentioned drawbacks, and uses a printing plate in which a solid line film is exposed to the plate material through a mesh film, and by making lined paper print, it can be used for copying, etc. The object of the present invention is to provide a lined sheet for use with photosensitive paper copying machine manuscript paper, which can be used as ruled paper for manuscript paper.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a lined sheet used for original paper in a photosensitive copying machine according to the present invention, and 1 is the lined sheet main body.

The lined paper main body 1 has horizontal or vertical contour lines 3 drawn on the paper 2 as appropriate, similar to conventional general lined paper.

Reference numeral 4 denotes mesh lines which are the main part of the present invention, and the printing method thereof will be described later.

In other words, the ruled lines of conventional lined paper are printed as solid lines as will be described later, and since this is printed on the assumption that the lined paper is simply a document paper, when copying, this line is printed as a solid line, as is the case with contour paper 3. Ruled line 4 is also copied as is.

The ruled lines 4 are mesh-like dotted lines, as shown in the opening of FIG. 1, and are completely different from the contour lines 3.

FIG. 2 shows how the original lined paper and the conventional lined paper are used.

First, to explain how conventional lined paper is used in Figure 2, when a graph 5 is drawn on the lined body 1 and copied using a photosensitive copying machine (not shown), the ruled lines of the lined paper become the outline 3. Similarly, it is printed with a solid line 6, so
Not only is the state of the graph 5 unclear because it is copied as is, but the graph 5 may not have any meaning at all, which is inconvenient or inconvenient.

On the other hand, when the original lined paper is used as shown in Fig. 2A, when the halftone line 4, which is the solid line 6 of the conventional lined paper, is copied, it completely disappears and only the graph 5 is copied as is. Therefore, not only can graph 5 be copied accurately, but also an easy-to-read copy can be created since there are no extra ruled lines.

In this way, the use of regular lined paper is very convenient not only when you want to copy graphs, figures, patterns, etc., but also when you want to copy characters without ruled lines.

FIG. 3 shows a method of printing the original lined paper.

First, a solid line film 7 is prepared in advance by drawing each line of a desired lined paper into a film shape.

Next, this solid line film 7 is exposed to light 10 on a printing plate 9 through a mesh film 8, which is a mesh-like film, to create a printing plate.

If this printed plate material 9 is used for printing, a lined paper main body 1 as shown in FIG. 1 will be printed.

Further, a printing example thereof will be explained in detail.

Printing Plate A A block copy is created by pasting thick, medium, thin, etc. lines, letters, patterns, etc. onto a blank paper mount.

B. Once the block is completed, take a picture of the line drawing using a plate-making camera.

C. Once the line drawings have been taken, the film is developed to create a negative film.

Engineering: Burn this negative film onto a disc (aluminum plate).

At that time, a mesh film is inserted between the negative film and the disc and the film is printed.

That way, halftone dots will appear on the entire image.

E. Once the printing is complete, remove the negative film and the mesh film, cover the necessary halftone dots in the negative film with red shielding tape or red strip film, etc. to prevent light from passing through, and then reinstall the film on the same disc. Burn it.

In this case, the portion of the halftone dot portion that is not shielded becomes a 100% solid portion through which light passes.

Power After this printing is completed, the disk is developed and the print is completed.

Printing Paper A: As long as the printing paper is white, printing can be performed regardless of its thickness.

B. Blueprint copies can be printed on tissue paper, tracing paper, etc.

Printing A: For printing ink, use basic ink formulated as follows.

F gloss medium 50% F gloss primary color eye 27% F gloss resistant grass
5% Super Calton Yellow (ST4
049) 18% A If you insert lined lipo film into the halftone dots of lined paper and copy, you can make lined lined paper just like the original version.

In this way, as a result of repeated tests, we found that the combination of ink density and halftone dots is highly visible as lined paper, and in order to achieve the best harmony with the density that disappears when copying. , the basic ink with the above formulation was optimal.

Note that copying results suitable for each model of copying machine can be obtained as long as the copying machine is currently commercially available.

The solution to this problem is that if an ink with a high density is used, the copyability will be good, and if the ink density is low, the copyability will be poor.

Therefore, without setting the standard exposure, you can copy one test card using the copying machine you are using and easily determine the ink density value and ink composition ratio suitable for that copying machine. .

If combined lined paper is printed with this blended ink, a high-quality product can be printed.

Since the present invention is structured as described above, by copying the characters and figures written on the ruled paper for manuscript paper as they are, the necessary characters and figures can be printed without copying unnecessary solid lines such as ruled lines. , etc., and can be used in the same way as conventional ruled paper even when copying is not required.Furthermore, these ruled lines can be printed in a simple manner, improving performance and practicality. sex.

The present invention provides lined paper that can be used in combination with manuscript paper for a new and unique photosensitive copying machine that is excellent in all aspects including economy.
