Can all resin carbon tapes stored for too long still be used?

All resin carbon ribbons that have been stored for too long and have been tested for good printing performance under ideal conditions can still be used. However, its actual usability will be affected by various factors, and the following is a detailed analysis of this issue:

1、 Shelf life of all resin carbon ribbon

In general, the shelf life of all resin carbon ribbon is between 3 to 8 years, but the specific time may vary depending on the manufacturer and storage conditions.

Carbon ribbon companies usually indicate on the label that they will use it within one year, but this is only a reference value. The shelf life of fully resin carbon ribbon stored under ideal conditions may be longer.

2、 The influence of storage conditions on carbon ribbon

The storage conditions of carbon ribbon have a significant impact on its service life. Severe environments such as high temperature, humidity, and direct sunlight can accelerate the aging and damage of carbon ribbons.

On the contrary, all resin carbon ribbons stored under dry, ventilated, and dark conditions may have a longer shelf life.

3、 Suggestions for using carbon ribbon with long storage time

For all resin carbon tapes that have been stored for too long, it is recommended to conduct a printing test before use. Observe whether the ink layer and back coating of the carbon ribbon are sticky, and whether the printing effect is good.

If the test results show good printing performance and there are no obvious signs of aging or damage to the carbon ribbon, it can continue to be used.

If the test results show poor printing performance or signs of damage such as aging and adhesion on the carbon ribbon, it is not recommended to continue using it.

4、 Precautions

The quality of the carbon ribbon axis may also affect the storage and usage effectiveness of the carbon ribbon. The quality of paper shafts produced by different manufacturers may vary, so the quality of shafts should also be taken into account when selecting carbon ribbons.

When using all resin carbon ribbons with long storage time, attention should also be paid to adjusting the printing parameters of the printer, such as printing speed, temperature, etc., to adapt to the aging of the carbon ribbons.

In summary, all resin carbon ribbons that have been stored for too long under ideal conditions and have been tested for good printing performance can still be used. However, sufficient testing should be conducted before use, and attention should be paid to the storage conditions and usage environment of the carbon ribbon to ensure its printing effect and service life.
