What are the main quality inspection items for all resin carbon ribbon?

The quality inspection of all resin carbon ribbon is a multi link and comprehensive process, mainly including the following items:

1、 Appearance inspection

Flatness: Check whether the surface of the carbon ribbon is flat, without waves, wrinkles, or bends.

Surface defects: Observe the surface of the carbon ribbon for scratches, white spots, pinholes, stains, and other defects.

Color uniformity: Confirm whether the color of the carbon ribbon is uniform and there is no obvious color difference.

Paper core condition: Check if the paper core is centered, if there is any edge running, and if the inner diameter of the paper core meets the requirements of the printer.

2、 Physical performance test

Tensile strength: Test the resistance of carbon ribbon under tensile force to ensure that it is not easily broken during transportation and use.

Bending strength: Evaluate the performance of carbon ribbon during bending to prevent damage caused by excessive bending.

Impact strength: Test the ability of carbon ribbon to withstand impact and ensure that it can remain intact in complex environments.

3、 Chemical performance test

Resin content: Determine the proportion of resin components in the carbon ribbon to ensure good adhesion and printing effect.

Moisture content: Check the moisture content in the carbon ribbon to avoid the impact of excessive moisture on printing quality.

4、 Printing performance test

Ink adhesion test: Through adhesion testing, ensure that the ink layer of the carbon ribbon will not easily fall off during the printing process, ensuring printing clarity and durability.

Wear resistance test: Evaluate the durability of carbon tape after printing, especially in label applications that require long-term preservation.

Heat resistance test: to test the performance of carbon ribbon in high temperature environment, ensuring that it can maintain good printing effect under different temperature conditions.

Compatibility testing: Confirm that the ribbon can work well with printers of different brands and models without causing damage to the equipment.

5、 Other specific performance tests

Chemical resistance test: Place the carbon ribbon sample in a specific chemical solvent to evaluate its ability to resist chemical corrosion.

Semiconductor and conductivity testing: For carbon tapes with special requirements, such as those used for electronic label printing, these tests may be necessary.

Printer printing energy level test: Test the printing effect of carbon ribbon at different printing energy levels to ensure its performance stability in practical applications.

6、 Marking and packaging inspection

Product identification: Check if there is clear product identification on the carbon ribbon packaging, including brand, specifications, production date, shelf life, and other information.

Packaging quality: Confirm whether the carbon ribbon packaging is intact and can effectively protect the carbon ribbon from external environmental damage.

Through the comprehensive quality inspection projects mentioned above, it can be ensured that the quality of all resin carbon ribbon meets industry standards and customer needs, improving printing quality and equipment lifespan.
