Taber Abrasion

This test is used to determine the amount of a printed image removed as a result of abrasive forces applied directly to the surface. Before testing, the optical density of the image (predetermined by the test standard) is measured using a densitometer and recorded. The image is carefully mounted on the Taber specimen holder with the plate, nut, and clamp. The weighted arms, which each contain a Calibrase wheel are carefully lowered onto the specimen along with the vacuum nozzle. The vacuum is turned on and the specimen is abraded for 20 revolutions. The specimen is removed without touching the abrasion area and any loose material is swept away with a clean brush before the final optical density is read and recorded. The initial and final densities, Di and Df, respectively, are used to calculate the abrasion resistance index, AI using the following formula:

AI = 100-(2[Df – Di])

We then measure this index against our ranking order to determine whether it performs up to standard.

We follow ASTM International Designation F1478 – 95: Standard Test Method for Determination of Abrasion Resistance of Images Produced from Copiers and Printers (Taber Method) as a guideline for our Taber abrasion tests.

A Message from our CEO

In an effort to keep all our customers informed, we want to share with you the following updates.

We are committed to keeping our employees, customers, and communities safe. In the wake of this pandemic, we took swift action to mobilize a significant number of our global team to remote working arrangements while enhancing our cleaning procedures and securing our production facilities to prevent the spread of the virus COVID-19.

As we continue to work through this pandemic, our core values have shone through, and we remain operational and dedicated to meeting the expectations and needs of our customers. Very early on, we increased our inventories, and we are in regular contact with our suppliers to monitor their status. We have maintained a high level of production, and our supply chains are meeting our requirements. However, we do prioritize firm orders above forecasts. Because this is a very fluid situation, we encourage you to make sure you have orders in place with us to carry you through these unusual times.

We will continue to keep you updated as this situation evolves. Meanwhile, stay safe and take care.


Gregory A. Woods
President & CEO
