"Metallic doming" refers to a new and unique effect in narrow web label printing: a metallic, mirror-like, raised structure created by a relief produced in rotary screen printing. What is so unique about metallic doming? Quite simply, it is a permanent metallic relief effect on paper or plastic film, such as tube laminates or transparent self-adhesive material.

As a system solution provider for label printers, Gallus has remained true to its credo and, with its "metallic doming" application process, has once again demonstrated that Gallus continues to set new standards in combination printing for narrow web label printing. With "metallic doming," the print image is applied using rotary screen printing. A metallic foil is then laminated over the relief. What makes this process so special is that it allows print images with permanent metallic reliefs to be produced on plastic – the only process on the label market to date that allows plastic to be given an embossed effect. This is because, apart from hot foil embossing without a permanent relief effect, plastic cannot be embossed unlike other materials. "Metallic Doming" closes this technological gap in the application field.

During "metallic doming", a thermoreactive glue is applied using screen printing with Gallus Screeny DY, for example, and then dried with UV light. After that, the applied print image is laminated with a thermoactive, metallic foil. A soft, heated laminating cylinder presses the foil onto the glue. The foil wraps around the glue and, together with the glue, is heated by the laminating cylinder. This laminating process reactivates the glue and activates the foil.
This thermal activation means the foil sticks to the glue. After this, the printed image cools to reveal a metallic relief effect – this is the "metallic doming effect".
