What are the quality inspection standards for enhanced mixed carbon ribbon?

The quality inspection standards for enhanced mixed carbon ribbon mainly include the following aspects:

1、 Appearance and identification

Surface quality: The surface of the carbon ribbon should be flat and free of obvious defects such as bubbles, impurities, scratches, etc.

Color and printing: The color should be uniform and consistent, and the printed text or pattern should be clear.

2、 Printing effect

Clarity: Use carbon tape for printing testing to observe whether the printed text or patterns are clear, without blurring, missing words, fading, or other issues.

Stability: Continuous printing test to check the stability of the printing effect, ensuring that the carbon ribbon can maintain consistent printing quality at different time periods and printing batches.

Durability: Evaluate the durability of carbon ribbon printing, especially for labels that require long-term storage, to ensure that the printed content is not easily faded or peeled off.

3、 Material and performance

Coating surface uniformity: Test the uniformity of the carbon ribbon coating surface to ensure that the ink can be evenly distributed, thereby improving printing clarity.

Adhesion: The adhesion test is used to ensure that the ink layer of the carbon ribbon will not easily fall off during the printing process, which is crucial for printing clarity and durability.

Scratch resistance: Evaluate the scratch resistance of carbon ribbon printing to ensure that the label will not be damaged or fade when subjected to friction or scratching.

Weather resistance: Test the performance of carbon ribbon under different environmental conditions, such as high temperature, low temperature, humidity, etc., to ensure that the carbon ribbon can adapt to various complex environments.

4、 Compatibility

Printer compatibility: Check if the ribbon is compatible with various models of printers to ensure that the ribbon fits well with the printer and does not cause damage to the equipment.

Material compatibility: Test the compatibility of carbon ribbon with different label paper materials to ensure the best printing effect.

5、 Convenience of use

Installation and replacement: A good carbon ribbon should be easy to install and replace, ensuring that users will not encounter too many difficulties during use.

Cardboard and ink jam: Test whether the carbon ribbon is prone to problems such as paper jam and ink jam during the printing process to ensure a smooth printing process.

6、 Certification and standards

SGS certification: Each carbon ribbon should undergo rigorous testing and obtain certification from relevant certification bodies such as SGS.

Product inspection standards: Carbon ribbon should comply with relevant national or industry inspection standards, such as GB/T 28439-2012.

In summary, the quality inspection standards for enhanced hybrid carbon ribbon cover multiple aspects such as appearance and labeling, printing effect, material and performance, compatibility, ease of use, and certification and standards. These standards together constitute an important basis for evaluating the quality of carbon ribbons, ensuring that they can meet printing needs in various complex environments.
