Sublimation printing
Sublimation printing makes the effects permanent, full-color images that won’t crack, peel or wash away from the substrate, as the ink is embedded in the fabric or substrate rather than simply laying on top.

Heat-Setting
Maintenance of good dimensional stability by heating (resistance to elongation and shrinkage). A important step for webbing made partly of thermoplastic materials (polyester, nylon…) which must be used at fixed lengths.
