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.

Abstract: The present disclosure provides for a liquid electrophotographic (LEP) ink comprising a carrier fluid, a pigment, a high melt viscosity ethylene acrylic acid copolymer resin, and a high acid ethylene acrylic acid copolymer resin. The high acid ethylene acrylic acid copolymer resin can have an acid content of at least 15 wt % and a viscosity of at least 8,000 poise. Additionally, the LEP ink can have a total resin acidity of at least 15 wt % and a total resin melt viscosity of at least 20,000 poise.
