What is the abrasion resistance of ink?

The abrasion resistance of an ink is its ability to maintain its colour, texture, adhesion and other key properties when subjected to mechanical action such as friction, abrasion or rubbing. The abrasion resistance of an ink is not a fixed value but depends on a number of factors, including ink composition, ink usage, stress conditions and environmental conditions.

Evaluation of ink abrasion resistance usually involves experimental testing and the use of quantitative or qualitative methods to measure and evaluate abrasion resistance. These tests can involve standard test methods such as ink abrasion tests, friction tests, rubbing tests etc. Through these tests, indicators such as the amount of wear, the degree of colour fading, coating breakage, gloss loss, etc. can be obtained to assess the abrasion resistance of the ink.

However, there is no universal or standardised value for the abrasion resistance of inks. Abrasion resistance requirements vary depending on the application and specific needs. For example, in the field of printing and packaging, inks with high abrasion resistance may be required to ensure that printed materials do not wear out or fade during transport and handling. In other areas, such as artwork or interior decoration, the requirements for abrasion resistance may be relatively low.

In practice, the abrasion resistance of an ink is usually determined by comparing it with other inks or materials. For example, samples of different inks can be tested under the same conditions and the relative abrasion resistance between them can be assessed on the basis of differences in indicators such as the amount of abrasion and the degree of discolouration.

Therefore, the abrasion resistance of inks is relative and related to specific applications and requirements. When selecting inks, it is recommended to refer to relevant industry standards and specifications and to communicate with suppliers to ensure that the ink meets specific needs and has the required abrasion resistance.
