Development history of thermal printing paper
In the 1930s, wax-type thermal printing paper using thermal recording was first used in electrocardiography.
In the 1940s, the United States developed a thermal copy method that uses infrared rays as a heat source to turn the original image into a thermal image.
In the 1950s, the 3M Company of the United States invented the thermal printing paper of the metal compound system.
In the 1960s, NCR Company invented thermal printing paper using the reaction of leuco dyes and phenolic compounds, which is also the most widely used thermal recording method.
In the 1970s and 1980s, the application of thermal printing paper in communication and faxing developed rapidly, the annual output increased rapidly, and the technology also made great progress. The recording speed changed from the G1 machine to the current G4 machine.
After the 1990s, thermal fax paper was affected by the gradual popularization of plain paper fax machines, and the output of thermal fax paper declined. However, the application of thermal printing paper in other fields is still developing rapidly.
Characteristics of thermal printing paper
It is easy to use and suitable for various thermal recording devices; the thermal recorder itself is cheap, simple and compact, almost maintenance-free, and has low recording noise; the recording is fast, and the text pattern is clear; the recording pattern and text have a short storage period, usually only one time. Year; the price is higher than ordinary paper.
