Abrasion Sensitivity Test
Abrasion damage to prints can occur when they are pulled from a stack, when a stack of prints is moved from one location to another, or when they are accidentally subjected to rubbing action by other materials such as storage enclosures. According to IPI’s research of digitally printed materials, the most objectionable characteristic of abrasion is colorant smearing into light areas of the print. Change in gloss has also been detected and is of concern when evaluating the effects of abrasion.
For our abrasion test, printed samples are abraded using a Sutherland 2000 Rub Tester®. Sample types are generally tested in triplicate and results are averaged. Smear of colorant from a black patch into a white patch in the test target is measured using image analysis software and hardware, while gloss in the black patch is measured with a gloss meter. Abrasion tests are done under temperature- and humidity- controlled conditions (21°C/70°F and 50%RH). The collected data is analyzed and a full report, including an explanation of the test method, is provided to the customer.
Note: For abrasion studies, we only perform benchmark/comparative tests, as we do not have a relative gauge to predict what the amount of abrasion measured in the test translates to in actual experience.
All test results are confidential.
What We Need
For the abrasion testing, the customer provides IPI with the printed test targets and the materials to be used as abraders. The target to be printed can be downloaded here: Abrasion Target (8.5x11). We need 5 copies for each sample (paper/substrate/abrader combination) being submitted for tested. This target should be printed on an 8.5 x 11 inch sheet (if your substrate does not come in this format, please contact us and we will send you a new target; DO NOT resize).
Materials for testing should be shipped to:
Attn: Andrea Venosa (Abrasion)
Gannett Building 7B, Room 2000

- For each sample (i.e. each substrate/colorant/abrader combination): $225
- Minimum charge: $1000
