Colour: solvent-ink films tend to darken after lamination; water-based films stay more vivid and keep more of the original colour.

Pattern clarity: water-based printing gives clearer layering and more complete definition.

Colour fastness: both pass 300 h UV exposure with ΔE < 8, with water-based films averaging lower.

Chemistry: both comply with REACH; water-based films have a greener composition.

Environmental performance: water-based films fully meet eco-label standards — 0 formaldehyde, 0 benzene solvents, 0 harmful residue.
