All Pelliconi closures can be customized according to the specific requirements of the customer. The decoration of the caps with multi-colour offset printing can be applied inside and outside the closure. To print code inside the cap, both ink-jet and laser methods can be used. Ink-jet printing is optimal for univocal alphanumeric codes. Laser printing is ideal for printing repetitive or highly variable images and univocal alphanumeric codes or a combination of both. Offset printing is ideal for multicolour graphics. In all these cases it is possible to apply to the cap white, colored or transparent seals and matte/opaque peel-off seals as well. Pelliconi has also developed a digital printing system for maximum customization of caps even in small batches.
