Description

[Detailed explanation of the invention] This invention was developed for recording paper for measurement, especially for recording interruptions.
This invention relates to measurement recording paper that prevents bleeding and allows recorded contents to be easily read.

Measurement recording paper has symbols such as scale lines, scale letters, and numbers printed on the recording surface (paper surface), and this is set in a recording device and the recording results of the recording device are drawn on it with a recording pen. I try to do that.

The biggest problem with such measurement recording paper is that the ink from the recording pen runs,
In this case, the recording paper for measurement is printed with oil-based ink, and in contrast, the recording ink is water-based or oil-based and non-drying. The purpose of this is to prevent the recording ink from drying out and not being printed.

However, when this recording ink is positioned on the scale line printed by the above-mentioned oil-based printing ink, there is a phenomenon in which both inks come into contact and are repelled, and this phenomenon causes an interruption in the recorded content. It has been pointed out that there is a problem in that the recording ink penetrates into areas that are not printed, and this area appears as a bleeding phenomenon, making it impossible to read the recording accurately.

FIG. 1 is for explaining this phenomenon. On the recording surface 2, that is, the front side of the recording paper 1, recording lines are made with oil-based printing ink 4 at predetermined intervals. The ink 3 can be drawn continuously on the portion of the recording paper 1, and is impregnated into the recording paper 1 so that good recording lines can be drawn.
In addition, when the recording ink 3 contacts and passes through a ruled line or the like formed by the printing ink 4 in this state, a repelling phenomenon occurs if the wettability between the two is poor.
Furthermore, the ink flows out along the sides of the recording line in a direction perpendicular to the plane of the paper due to capillary action, causing large bleeding in this area.

This invention was created in view of the above-mentioned shortcomings, and its purpose is to prevent blurring and discontinuity of recording lines on measurement recording paper, and to make it possible to read recorded contents easily and clearly. The purpose of this paper is to provide recording paper with a high quality.

An embodiment of this invention will be explained below using FIG. 2. In FIG. It is formed into a substantially transparent or semitransparent shape by size pressing, and its recording surface, that is, the surface 21 side, is extremely smooth.
It is configured to be recorded with water-based ink, and although the smoothness of the recording back side 31 is slightly inferior to this level, it still maintains smoothness.

And the back side 31 of the recording paper configured in this way
The scale lines or necessary symbols are printed with oil-based printing ink 41 in an inverted state, and when such printed items are seen through from the front side, for example, symbols can be seen in their normal state. It's becoming like that.

Therefore, the measuring recording paper constructed as described above is set in a measuring device such as a recorder with its recording side facing up, but when it is set in a measuring device such as a recorder, the present invention does not apply. Such recording paper is a substantially transparent or translucent recording paper whose front surface is used as the recording surface for recording with water-based ink, and the back side of this recording paper is printed with scale lines and necessary symbols using oil-based ink. There is no risk of the printing ink and the recording ink coming into contact with each other, and therefore the repelling phenomenon can be prevented. Therefore, it is possible to prevent phenomena such as interruption of the recording line and bleeding on the recording paper due to contact between the two inks, and since the recording paper is made of substantially transparent or semi-transparent base paper, the printed matter printed on the back side can be prevented. can be clearly recognized, making it extremely easy and clear to read the recorded content from the recording with the recording pen and the printed matter on the back side.

Claims (1)

[Scope of utility model registration request] The surface of the almost transparent or translucent recording paper is used as the recording surface to be recorded with water-based ink, and the scale lines and necessary symbols are printed in reverse with oil-based ink on the back side of the recording paper, and the printed items are printed on the surface. A measurement recording paper characterized by being made to be visible from the side.
