Curious is a collection of printing surfaces, with special textures or effects. The surfaces are used as the base material on which full colour prints can be printed. The surfaces can be used for the packaging of goods, food (bread for instance) or other materials.
In total there are five different printing surfaces available:

Curious Metallics: glittering metal-effects alloys and shimmering, light-flipping iridescents.
Curious Particles: recycled sheets with fibres that are pale or gleaming, or change colour and disappear.
Curious Touch: unusually tactile surfaces: floppy Wet, fuzzy Soft and classic cotton Arches.
Curious Translucents: see-through sheets – some patterned or flecked, all in unique designer hues.
Curious Plastics: mellow, a slippery, bendy sheet that feels like printable rainwear.
