How to test the scratch resistance of colored mixed carbon ribbon?

The scratch resistance of colored mixed carbon ribbon can be tested by the following steps:

1、 Preparation work

Testing equipment: Ensure to have a dedicated printer and specialized paper or testing media for wiping and testing. Meanwhile, prepare a scratch tester (if conditions permit) for more accurate testing.

Carbon ribbon sample: Prepare the color mixed base carbon ribbon sample to be tested and ensure that it has been correctly loaded onto the printer.

Printing parameters: Adjust the printing parameters according to the printer's instructions to ensure the best printing effect.

2、 Print test samples

Printing test patterns: Use colored mixed carbon ribbon to print test patterns containing text, numbers, symbols, and graphics on the test medium. Ensure that the test pattern is clear, complete, and covers the entire testing area.

Drying treatment: After printing is completed, let the test sample dry naturally for a period of time to ensure that the ink is completely cured.

3、 Scratch resistance test

Manual wiping test:

Use a clean soft cloth or tissue dipped in an appropriate amount of solvent (such as alcohol, water, etc., depending on the compatibility of the carbon ribbon and medium) or directly wipe with a dry cloth.

Wipe the test pattern back and forth several times with appropriate force and speed, and observe whether there are obvious scratch marks or fading phenomena.

Scratch tester test (if conditions permit):

Place the test sample on the scratch tester and set the test parameters (such as scratch speed, force, frequency, etc.) according to the instructions of the tester.

Start the tester for testing and observe the test results.

4、 Observation and evaluation

Observe scratch marks: Carefully inspect the scratch marks on the test pattern, evaluate their quantity, size, and depth.

Evaluate scratch resistance: Based on the observed scratch marks, evaluate the scratch resistance of the colored mixed carbon ribbon. If there are few and slight scratch marks, it indicates that the scratch resistance of the carbon ribbon is good; On the contrary, it indicates poor performance.

5、 Precautions

Testing environment: Ensure that the testing environment is clean and dust-free to avoid external factors affecting the test results.

Test frequency: In order to improve the accuracy of the test, multiple tests can be conducted and the average value can be taken as the final result.

Record data: During the testing process, record the test parameters, observation results, and evaluation conclusions in detail for subsequent analysis and improvement.

Through the above steps, the scratch resistance of colored mixed carbon ribbon can be evaluated, providing reference for its selection in practical applications.
