a system for printing adhesives immerses a wire in a reservoir of adhesive for a period of time sufficient to allow the wire to be coated with the adhesive . the system places the coated wire in close proximity to a designated medium onto which the adhesive will be applied and directs a stream of gas to contact the coated wire and cause at least some of the adhesive on the wire to be deposited onto the designated medium . two - part ink systems include a fluid and a second material that is microencapsulated in the fluid , a second material that exists as a microemulsion in the fluid , and two fluids that are mixed or combined upon jetting and that react on the print medium .
