How to detect the quality of mixed carbon ribbon?

The quality of mixed carbon ribbon can be tested from the following aspects:

1、 Appearance quality inspection

Surface flatness: Check whether the surface of the carbon ribbon is flat, without obvious defects such as deformation, bubbles, impurities, scratches, etc.

Color uniformity: Observe whether the color of the carbon ribbon is uniform and consistent, without obvious color differences or spots.

Packaging integrity: Check whether the packaging of the carbon ribbon is intact, without cracking or damage, to ensure that the carbon ribbon has not been damaged during transportation and storage.

2、 Physical performance testing

Width and thickness: Use measuring tools to check whether the width and thickness of the carbon ribbon meet the specifications.

Tensile strength: Test the tensile strength of carbon ribbon to ensure that it is not easily broken during the printing process.

Fracture elongation: Measure the elongation of carbon ribbon before fracture to evaluate its flexibility and durability.

Curliness: Check if the carbon ribbon has good curling to ensure that it can be smoothly wrapped around the printer core shaft.

3、 Thermal transfer performance test

Printing density: By printing test samples, observe whether the printing density of the carbon ribbon is uniform, without missing or incomplete printing.

Resolution: Check the resolution of the printed sample to ensure that the ribbon can print clear and delicate images and text.

Scratch resistance: Use scratch testing tools to evaluate the durability of carbon ribbon printing, ensuring that it can resist daily wear and scratches.

Weather resistance: Test the performance of carbon ribbon in high temperature, low temperature, lighting and other environments to ensure that it can maintain good printing effect and stability.

4、 Chemical performance testing

Chemical stability: Check whether the carbon ribbon is easily dissolved or deformed by solvents to ensure that it does not undergo chemical reactions with the printing medium or printer components during the printing process.

Harmful substance detection: Conduct harmful substance detection on the chemical components used in carbon ribbons to ensure that they do not contain any substances harmful to user health.

5、 Compatibility testing

Printer compatibility: Test whether the carbon ribbon is suitable for various models of printers to ensure that it can work perfectly with the printer without paper jams, ink jams, and other malfunctions.

Compatibility of printing media: Check whether the carbon ribbon is suitable for different types of printing media, such as paper, plastic film, etc., to ensure that it can print high-quality images and text.

6、 Printing effect evaluation

Clarity: Observe the clarity of the printed sample to ensure that the carbon ribbon can print clear and easy to read text and images.

Stability: Continuously print multiple samples and observe whether the printing effect is stable and consistent, without significant fluctuations or changes.

Durability: Evaluate the durability of carbon ribbon printing to ensure that it can maintain the same printing effect for a long time.

In summary, the quality of mixed carbon ribbon testing needs to be comprehensively considered from multiple aspects. Through steps such as appearance quality inspection, physical performance testing, heat transfer performance testing, chemical performance testing, compatibility testing, and printing effect evaluation, the quality level of carbon ribbon can be comprehensively evaluated, and high-quality mixed base carbon ribbon can be selected.
