Information about tests
Wrinkle resistance of printing inks or lacquers - dry or after immersion in water
The test may be carried out on printings, coatings on flexible substrates such as films or paper. In addition to an examination after immersion in water, testing after storage in filling goods, after UV irradiation or mechanical stress is of course also possible.
| test method: | Mechanical/ technological properties |
| Norms: | - |
| Needed sample size: | Sample over total width of material, minimum 5 repeating patterns |
