This process can reproduce any photographic image directly onto metal and is ideal for images with graduated colours. Normally made on either a Stainless Steel or Brass base and the image can be printed to the edge or leave a border visible. This process is always protected by an epoxy coating. Full 4 colour process printing is used for multi or graduated colour images and results can be excellent for complex designs where paint fill processes are not an option. This process is normally used for badges and key rings.
