Off-set print: an image of the design is transferred from a photographic negative onto the surface of the metal base. The offset printed style of lapel pin is used in when a gradient of color shift is necessary in the design. Using the offset printed process manufacturers are able to print images, pictures, and camera ready artwork using the 4-color process. The image on the negative is offset printed onto the pin, with a choice of either gold or nickel (silver) as a base metal, then a clear epoxy dome is applied on the surface of the print as a protective film over the image. It is recommended that 300dpi Camera ready artwork is used for this process to ensure that the image is of high quality and readily formatted for printing.Offset printed lapel pins have an exact replication for your lapel pin artwork. Any lapel pin shapes can be custom made as offset printed pins.
