How to test the scratch resistance of colored all resin carbon ribbon?

The scratch resistance test of colored all resin carbon ribbon is an important indicator for evaluating its ink adhesion and wear resistance after printing. The following are the steps and methods for testing the scratch resistance of colored full resin carbon ribbon:

1、 Test preparation

Testing equipment: Prepare a scratch resistance tester or similar friction testing equipment. These devices usually have controllable friction force and friction frequency, which can simulate the scraping situation in actual use.

Test sample: Use colored full resin carbon tape to print test patterns and text on standard test materials such as copperplate paper, PET paper, etc. Ensure that the printing quality of the test samples is good and there are no obvious defects.

Testing environment: Ensure a stable testing environment and avoid the influence of environmental factors such as temperature and humidity on the test results.

2、 Test steps

Set test parameters:

According to the testing requirements, set the friction force, friction frequency and other parameters of the scratch resistance tester. The friction force is usually determined based on the scraping strength in actual application scenarios.

Choose a suitable friction head to ensure that its contact area and shape with the test sample meet the testing requirements.

Perform testing:

Fix the test sample on the scratch resistance tester, ensuring that the testing area is completely exposed under the friction head.

Start the scratch resistance tester and conduct friction testing according to the preset parameters.

During the testing process, pay attention to observing the changes in the test sample, record the number of friction cycles, and any damage, fading, or other phenomena that occur.

Evaluate the test results:

After the test is completed, carefully inspect the printing area of the test sample and evaluate its scratch resistance performance.

Based on the test results, determine whether the ink adhesion and wear resistance of the colored all resin carbon ribbon meet the requirements.

3、 Precautions

Consistency of test samples: Ensure that the printing quality, material type, and other conditions of all test samples are consistent in order to accurately evaluate the scratch resistance of colored all resin carbon tape.

Calibration of testing equipment: Before using the scratch resistance tester, ensure that it has been calibrated to ensure the accuracy and reliability of the test results.

Control of testing environment: During the testing process, the temperature, humidity, and other conditions of the testing environment should be strictly controlled to avoid the influence of environmental factors on the test results.

Multiple testing and taking the average: To improve the accuracy of the test results, it is recommended to conduct multiple tests and take the average as the final result.

In summary, testing the scratch resistance of colored all resin carbon ribbon requires the preparation of corresponding testing equipment and samples, and testing should be carried out according to certain steps and methods. By evaluating the test results, it is possible to determine whether the ink adhesion and wear resistance of the colored all resin carbon ribbon meet the requirements, providing strong support for selecting suitable products.
