Abstract:
A method of printing a security code on an article includes applying droplets of an ink composition with an ink jet printer to a surface of an article to print an encrypted code. The ink composition includes an organic solvent, a binder resin, and a luminescent dye.
Abstract:
An apparatus for determining the resistance of a printing element of a print head, the apparatus comprising: a print head comprising a plurality of individually controllable printing elements connected in parallel, and a capacitor connected in parallel with the printing elements; a test voltage supply arranged to supply a test voltage to the print head; a current monitor arranged to measure the current supplied to one of the printing elements when the said one of the printing elements is connected to the test voltage supply; and a controller arranged to determine the resistance of the said one of the printing elements based upon the measured current.
Abstract:
A method and system for remote servicing of an industrial printer includes obtaining, on a processor, sensor data that indicates values output by a sensors configured to measure physical phenomena related to a plurality of components of the industrial printer. Also obtained, on the processor, is parameter data that indicates values for parameters that indicate user settings for operation of the industrial printer. It is determined, on the processor, a service issue related to the industrial printer based on the sensor data and the parameter data, It is also determined, at least in part on the processor, an action to be performed on the industrial printer in response to the service issue. Furthermore; the action is caused to be initiated. In some embodiments, the action is initiated at one facility different from a facility where the industrial printer is located.
Abstract:
A method for measuring the volume of liquid, such as ink or solvent, remaining in a container, such as a replacement cartridge for a continuous ink jet printer, uses a reservoir enclosing an internal space having a variable volume for storage. The reservoir is adapted to provide a reduction in the pressure of the internal space, the reduction substantially monotonically increasing in magnitude as liquid is drawn into the printer, such that the volume of liquid remaining may be calculated from knowledge of the minimum withdrawal pressure required to draw further liquid from the reservoir into the printer. Containers for use with the method have a liquid dispensing port adapted to allow liquid to be dispensed when a withdrawal pressure at the exterior of the port is less than the pressure of the internal space and adapted to prevent the ingress of air into the internal space of the reservoir as liquid is dispensed.
Abstract:
An ink jet ink composition includes an organic solvent in an amount between 60% and 95% by weight of the ink composition, a binder resin, a stabilizing agent, which may be provided by the binder resin, and a pH sensitive dye. An image formed by the ink composition changes from a first color to a second color when exposed to water, wherein the first color is different than the second color.
Abstract:
A capping device for an ink jet print head, includes a base, the base configured to receive an ink jet print head comprising nozzles for ejecting ink in a print direction, and a cap assembly attached to the base and configured for movement between a closed position when the print head is not printing and an open position to allow for the ejection of ink from the nozzles when the print head is printing. The cap assembly includes a cover support configured for generally planar movement with respect to the base in a direction perpendicular to the print direction and a cover attached to the cover support in a generally planar relationship thereto. The cover is adapted to provide additional movement with respect to the cover support in a direction different from the planar movement in the direction perpendicular to the print direction.
Abstract:
A method of printing a product code includes providing a printer and a substrate. A product code is determined. The product code includes a plurality of characters and a key code. The key code includes an interleaved character including a combination of a first character and a second character selected from the plurality of characters. The printer is controlled to print the product code on the substrate.
Abstract:
An ink jet ink composition includes an organic solvent, a binder, and a colorant. The colorant is selected from at least a first pigment and a second pigment. If the ink composition comprises carbon black, the carbon black is present in an amount less than 30% by weight of the total pigment content.
Abstract:
A method for printing images on a substrate with an ink jet printer includes providing a liquid ink composition. The liquid ink composition includes an organic solvent, a binder, and a colorant. Droplets of the ink jet ink composition are directed to a plastic film substrate. The droplets are allowed to dry, thereby printing a durable graphic image on the substrate.
Abstract:
A bracket for a printer includes a frame with first and second side supports. A print area is defined in part by the side supports. A plurality of web support members laterally extends between the first and second side supports. The plurality of web support members include a top web support member disposed adjacent a top portion of the print area and a bottom web support member disposed adjacent a bottom portion of the print area. A printer support is configured for supporting a printer adjacent the print area. A window assembly is hingedly attached to the frame adjacent the print area. The window assembly includes a platen support member extending laterally between the first and second side supports. The window assembly is movable to provide access to the print area. At least one platen is disposed on the platen support member, the platen adapted for lateral positioning along the platen support member.
