Description

Record recording paper for measuring equipment and manufacturing method thereof {THE METHOD OF PREPARING INSTRUMENT RECORDER CHART PAPER}

The present invention relates to a method of manufacturing record recording paper for measuring equipment, and more particularly, to effectively fix the ink of the oil and water pens used in the record for measuring equipment, and to form a surface layer that is processed to prevent smearing. The present invention relates to a method for manufacturing record recording paper for measuring equipment.

Although most of the measurement record records used in the past are imported products, measurement records produced in Korea do not exceed the level of writing paper or printing paper, and the surface size treatment is applied to water-based ink. Although there is little bleeding, there is a problem that the recording is not clear because there is insufficient resistance to absorption of oily substances such as oil and there is no excellent absorbing layer capable of adsorbing and fixing the ink layer effectively.

General writing paper absorbs printing ink when it comes into contact with writing instruments or printing containers for a short time, but in case of recorder recording paper for measuring equipment, it is recorded by contacting recording pen on paper surface. Consistent with the absorbency of oil-based ink.

Generally, the resistance of the paper to solvents such as water or ink is called barrier aptitude, and when the paper has a uniform barrier aptitude as a whole, good quality printing is possible.

Since the recording paper is used by printing a chart of a certain standard, the ink of the recording pen must be smooth while the ink of the recording pen is not smeared or broken.

In particular, the recorder recorder for measuring equipment is a medium for recording information on the equipment. It should be able to be stored for a long time. In the long run, the company loses all of its recorded data over the years, causing a serious problem of losing its value as an information industry site.

Therefore, in the manufacture of record recording paper for measuring equipment, it gives the arithmetic ability to print the chart uniformly with excellent barrier performance against water-based ink and oil-soluble ink, and it is uniform even under extreme conditions unlike general printing paper such as high temperature and high humidity. The purpose of the present invention is to provide a method for manufacturing record recording paper for measuring equipment that has been provided with characteristics of stability (dimension stability) and less distortion.
