How to Print on Metal
Printing on metal is a great way to create unique and durable artwork, signage, or other items. There are a few different methods for printing on metal, each with its own advantages and disadvantages. Here is a guide to the most common methods:
Method 1: Sublimation Printing
Sublimation printing is a process that uses heat to transfer a design onto a metal surface. The design is first printed onto a special sublimation paper, which is then placed on the metal surface and heated. The heat causes the ink on the paper to turn into a gas, which then bonds with the metal surface. Sublimation printing produces high-quality, full-color prints that are resistant to fading and scratches.
Method 2: UV Printing
UV printing is a process that uses ultraviolet light to cure ink on a metal surface. The ink is jetted onto the metal surface and then exposed to UV light, which causes the ink to cure and bond with the metal. UV printing produces high-quality prints that are resistant to fading and scratches.
Method 3: Screen Printing
Screen printing is a process that uses a stencil to apply ink to a metal surface. The stencil is created by exposing a photoresist-coated screen to light, which hardens the photoresist in the areas where the design is not wanted. The hardened photoresist blocks the ink from passing through the screen, so when the ink is applied to the screen, it only passes through the areas where the design is wanted. Screen printing produces high-quality prints that are resistant to fading and scratches.
