Abstract:
Disclosed is an ink jet ink composition that forms indelible images on porous or semiporous substrates. The ink composition comprises a liquid carrier, a first colorant that is soluble in the carrier but insoluble or substantially insoluble in water, and a second colorant composition comprising a pigment, the second colorant composition being dispersible in the carrier. The second colorant composition is insoluble or substantially insoluble in the carrier. The images are difficult or impossible to remove or wash out by the use of aqueous and/or nonaqueous liquids.
Abstract:
According to certain aspects of an embodiment of the present invention, a deflection electrode assembly is provided for use in a continuous ink jet printer of the type which projects a stream of ink drops toward a substrate and controls placement of the ink drops on the substrate by selectively charging the individual ink drops and passing the charged ink drops through an electric (deflection) field created by the deflection electrode assembly. The deflection electrode assembly includes a high voltage deflection electrode and a low voltage deflection electrode positioned on opposite sides of the ink drop stream. A dielectric insulating member is mounted on at least one of the deflection electrodes. The insulating member include a longitudinal opening which exposes the deflection electrode along the path of the ink jet stream, thereby virtually eliminating the tendency for accumulated ink to decrease the strength of the deflection field. The insulating member extends inwardly and underlies the bottom face of the deflection electrode along at least its front and side edges. Providing insulation along the front and side edges of the deflection electrode reduces arcing between the deflection electrodes. Providing the longitudinal opening in the insulating member reduces the field distortion effects of micro-satellite ink drops that would otherwise accumulate on the insulating member.
Abstract:
Disclosed are jet ink compositions suitable for printing on substrates such as plastics and oil contaminated metals messages having excellent adhesion, for example, scratch resistance. The jet ink composition comprises one or more organic solvents, a rosin resin, and a colorant, and optionally a co-binder resin, e.g., a vinyl resin. Preferably, the jet ink composition is free or substantially free of a cellulose nitrate resin and/or a slow evaporating solvent. The present invention further provides a method for printing scratch resistant messages on a low surface energy substrate comprising projecting a stream of droplets of the jet ink composition to the substrate, controlling the direction of the stream so that the droplets are caused to form the desired printed messages, and allowing the messages to dry.
Abstract:
Embodiment of the present invention relate to a continuous inkjet ink composition which uses a higher order ketone solvent or solvents (ketones having 5 or more carbon atoms) in place or more hazardous solvents such as methyl ethyl ketone and a secondary solvent with a higher derived no effect inhalation level greater than 200 mg/m3 such as ethanol. These ink compositions contain a combination of resins including a cellulose resin and a polyurethane resin or an acrylic resin, with an optional third resin. A colorant (i.e., a dye, preferably a conductive dye) also is included.
Abstract:
There is provided a computer implemented method comprising, receiving data associated with an industrial printer, the industrial printer operating on a print line and executing a print job, determining, based on the data associated with the industrial printer, an issue associated with the industrial printer, determining, based on the issue, whether the industrial printer requires remedial action or if the industrial printer can continue to be operated with the issue.
Abstract:
A method implemented on a processor for operating an industrial printer comprises obtaining first data that indicates a representative industrial printer used on a production line at a facility and a product to be output by the production line; obtaining second data that indicates a target start time and a target number of the product and a target duration for producing the target number of the product; and upon a condition precedent, determining a line report that indicates productivity of the production line based on the count of print operations and the second data.
Abstract:
A method for monitoring a characteristic of a printed image of a thermal transfer printer. The method comprises providing a ribbon and a substrate at a printing location of the thermal transfer printer. The method further comprises printing an image on the substrate at the printing location by transferring ink from a region of the ribbon in a printing operation, a negative image being formed on the region of ribbon. The method further comprises transporting the region of ribbon, by a ribbon transport system, from the printing location towards an imaging location along a ribbon transport path. The method further comprises when a characteristic of the ribbon transport meets a predetermined criterion, obtaining, by an image capture system, a ribbon image of the negative image. The method further comprises processing said ribbon image to generate data indicative of the characteristic of the printed image.

Abstract:
A method and system for operating an industrial printer includes obtaining initial data that indicates the industrial printer used on a production line at a facility and a product to be output. Target data is obtained indicating target start time and target number of the product and target duration. The industrial printer is operated to report a count of print operations for the product at regular time intervals. Actual data is stored indicating the count and the time interval. Upon a condition, a line report is determined based on the count and the target data. The line report is presented on a display device. The condition is one or more of passage of the target duration after the target start time, passage of the target duration after a first print operation, a change in shift workers on the production line, a time of day, and a predetermined event.
Abstract:
There is provided a tape drive. The tape drive comprises first and second spool supports on which spools of tape may be mounted. The tape drive further comprises an optical sensing system. The optical sensing system comprises a radiation emitter and a radiation detector, said radiation emitter and radiation detector having a fixed positional relationship in use with respect to said first and second spool supports. The tape drive further comprises a controller. The controller is operative to, energise the radiation emitter to emit radiation, and determine a diameter data indicative of a diameter of a spool mounted on one of the first and second spool supports based on a radiation signal generated by the detector.
