摘要:
A printed mask derived from a composition comprised of at least one compound including at least one alkaline-hydrolyzable group, and at least one compound including at least one ethylene oxide group. The printed mask is removable using an alkaline solution in about 30 seconds or less.

摘要:
Ink reservoir subassemblies for phase change ink can be designed and configured to include at least one structure comprising elements disposed within the ink reservoir. The elements may include fibers and/or beads that occupy a majority of a volume of the reservoir. The elements may provide enhanced thermal conductivity, ink filtering and/or bubble reduction.
摘要:
Approaches to remove objects from ink in an ink jet printer are described. An object separator for an ink jet printer includes one or more inlets configured to allow passage of ink that includes objects such as bubbles and particles into the object separator. The object separator has a number of stacked plates. Some of the plates have curved channels which are connected through other plates that include vias. The plates are arranged to form at least one cyclonic flow generator, the cyclonic flow generator configured to focus the objects into one or more focused flow streams. The object separator includes one or more object outlets that allow objects to exit the object separator and at least one ink outlet that allows the ink to exit the object separator.

摘要:
Approaches to remove bubbles from ink in an ink jet printer are described. Bubble removal may be implemented using one or more separator elements configured to separate bubbles of a vapor from ink. Each separator element includes wicking features having dimensions sufficient to allow capillary movement of the ink in the wicking features and to substantially exclude the bubbles from the wicking features. One or more inlets allow passage of the ink that includes the bubbles into the separator element. At least one vapor outlet allows vapor that has been separated from the ink to exit from the separator element. The ink exits from the separator element thought one or more ink outlets.
摘要:
A system for removing ink from a substrate. The system includes an ink separator configured to separate the ink from the substrate; and a substrate conveyor configured to provide the substrate to the ink separator. Accordingly, the ink can be removed from the substrate such that the substrate can be re-used.
摘要:
A process for producing a low-visibility retroreflective visual tag, which can be used to identify and/or determine the position of an object. This process involves placing an infra-red-blocking material over a retroreflective substrate to form the low-visibility retroreflective visual tag. This infra-red-blocking material is placed so as to form a pattern, which becomes visible to an infrared sensor when the low-visibility retroreflective visual tag is illuminated by an infra-red light source.
