Abstract: A printer includes an image formation portion, a feed portion, and a transfer portion. The image formation portion transfers formed first and second patterned marking agent layers from a photoconductor member onto an intermediate transfer member. The feed portion directs a portion of a foil layer to become adhered, according to the pattern, onto the first marking agent layer on the intermediate transfer member before the second marking agent layer is transferred onto, and becomes adhered to, the foil portion. The transfer portion causes transfer of the foil portion from the intermediate transfer member, via transfer of at least the second marking agent layer from the intermediate transfer member, onto a substrate.
