  • Patent number: 10479074
    Abstract: A liquid droplet jetting apparatus includes: a carriage configured to scan in a main scanning direction; a jetting head installed in the carriage, having nozzles arranged in a sub scanning direction intersecting with the main scanning direction, and configured to jet liquid droplets from the nozzles; a conveyer configured to convey the recording medium in the sub scanning direction; and a controller configured to control the carriage, the jetting head and the conveyer. The nozzles form nozzle groups including two nozzle groups adjacent in the sub scanning direction; and the controller is configured to execute a predetermined printing mode in which a pass printing and conveyance of the recording medium in the sub scanning direction are alternately performed. The pass printing causes the carriage to move one time in the main scanning direction while jetting the liquid droplets from the nozzles.

  • Patent number: 10406830
    Abstract: Backing material is passed by a first heater to pre-heat the backing material. The backing material is then passed by a printing engine to print marking material on the backing material, and passed by a first light source to apply ultra-violet (UV) light to the marking material printed on the backing material, to partially cure the marking material. Further, the backing material is passed by a container to expose the partially cured marking material to adhesive particles to cause the adhesive particles to adhere only to the marking material. The backing material is passed by a second light source to apply additional UV light to the marking material partially cured on the backing material to fully cure the marking material. Finally, the backing material is passed by a second heater to melt the adhesive particles that are adhered to the marking material on the backing material.
