Office thermal paper is a paper product commonly used in equipment such as printers and cash registers. It has the characteristics of sensitivity, fast speed, and no need for ribbons, so it is widely used in office, business and other fields.
Detection method
Testing the performance of office thermal paper can include the following aspects:
Color rendering: The color rendering of office thermal paper is one of its most basic performance indicators. Evaluate its color rendering performance by testing its color rendering speed, color rendering degree, color depth and other parameters to ensure that the printing effect is clear and accurate.
Heat resistance: Since office thermal paper is printed by thermal printing technology, heat resistance is also an important performance indicator. The heat resistance test can measure its performance in high temperature environment to ensure that the print quality is stable and will not be damaged by heat.
Moisture resistance: In actual use, office thermal paper also needs to have certain humidity and moisture control capabilities to ensure printing quality and stability. The humidity resistance test can simulate its performance in a humid environment to ensure that it can still work normally in a humid environment.
Lightfastness: The lightfastness of office thermal paper is also an important performance indicator. In actual use, it may be exposed to sunlight and ultraviolet rays, so its light resistance needs to be tested to ensure print quality and long-term service life.
Cylinder wear: Since office thermal paper needs to be in direct contact with the cylinder of the printing device during the printing process, cylinder wear is also a performance indicator that needs to be tested. The roller wear test can evaluate the wear degree of the office thermal paper to the roller of the printing equipment during long-term use.
Test Methods
The specific test methods for office thermal paper performance include the following:
Color rendering test: Use a color rendering Tester or a thermal printer to test the color rendering performance of office thermal paper. These devices can simulate printing conditions in actual use and measure parameters such as color development speed, color rendering degree and color depth of office thermal paper.
Heat resistance test: Use heat treatment equipment or a hot box to test the resistance of office thermal paper in a high temperature environment. During the test, it is necessary to expose the office thermal paper to a high temperature environment, such as 50°C or 60°C, and measure its color rendering and clarity.
Humidity Resistance Test: Use a Humidity Chamber or other humidity control equipment to test the performance of office thermal paper in a humidity environment. During the test, the office thermal paper is exposed to a hot and humid environment, and its color rendering and clarity are measured.
Light fastness test: Use ultraviolet light source or fluorescent lamp to test the light fastness of office thermal paper. During the test, the office thermal paper is exposed to a light source, such as a UV light source for 48 hours, and then its color rendering and clarity are tested.
Roller wear test: Use a rub Tester or other wear testing equipment to test the wear between the office thermal paper and the printing device roller. During the test, the actual use process is simulated to measure the number of times the office thermal paper is in contact with the roller and the degree of wear.
Beichao reminds you: Different test methods may require different equipment and test conditions. The test should be carried out in a professional laboratory or testing institution, and follow the relevant standards and regulations to ensure the accuracy and reliability of the test results. In addition, safety matters need to be paid attention to during the test, such as preventing fire, burns, etc. from happening.
