Is Nyloflex ink suitable for customising nylon shoes?

Yes, I can confirm that Nyloflex ink adheres to nylon.

However, you need to be aware of the results that might be obtained from the different possible techniques.
Screen printing creates a very thin layer of ink (approximately 20 micrometres): as a result, although the ink itself isn’t particularly flexible, the design won’t crack as the material bends.

However, if the layer of ink that’s created using other techniques (brush, roller, etc.) is too thick, the ink can crack and look pretty unpleasant.

We therefore suggest that you carry out a preliminary test.
