The microstructures may serve for the printing of a refractive relief or a blind embossing.

As a result, far less bag material is required than in the prior art patterned film formed through cold embossing processes.

If KODAK NEXPRESS Dimensional Clear Dry Ink is used on its own, it is even possible to create transparent 3D effects to mimic blind embossing or to simulate textured surfaces and substrates.
