| 20100214373 | AUTHENTICATING A PRODUCT - This invention generally relates to a composition, an apparatus, and a method for authenticating a product. In particular, the invention relates to an ink composition for marking a product with a continuous inkjet printer. The composition includes a visible ink and a UV, visible, and/or IR marker. Marking includes depositing the ink composition on the product with the continuous inkjet printer. A marked product is authenticated with a hand-held apparatus that activates the marker in the mark with UV radiation. Activation of the marker in the mark changes the absorbance/reflectance of visible radiation by the mark without changing the visual appearance of the mark. Authenticity of the product is assessed by a change in absorbance or reflectance of visible radiation by the mark after activation of the mark. | 08-26-2010 |
| 20100321449 | CONTINUOUS INKJET PRINTING - A continuous inkjet method in which liquid passes through a nozzle, the liquid being jetted comprising one or more dispersed or particulate components and where the particle Peclet number, Pe, defined by | 12-23-2010 |
| 20110221834 | PRINT HEAD HAVING INTEGRATED DEFLECTING ELECTRODES - A print head of a continuous ink jet printer includes a housing that holds the components of the printer head. The housing is made of at least two housing parts that can be separated and that are particularly fastened to each other in an articulated manner. A cavity, that is traversed by the produced ink jet, is arranged between the housing parts. An insert is arranged on each of the housing parts and a cavity that is traversed by the ink jet is formed between the joined inserts. Surface areas of a respective insert that bound the cavity merge seamlessly with each other and form smooth surfaces without gaps, edges, or undercuts. | 09-15-2011 |
| 20110279554 | INKJET RECORDING MEDIUM AND METHODS THEREFOR - An inkjet receiving medium including a substrate and having a topmost layer coated thereon at solid content of from 0.1 to 25 g/m | 11-17-2011 |
| 20120026251 | LIQUID FILM MOVING OVER POROUS CATCHER SURFACE - A printhead includes a jetting module that forms liquid drops travelling along a first path. A deflection mechanism causes selected liquid drops formed by the jetting module to deviate from the first path and begin travelling along a second path. A catcher includes a stationary porous surface. A liquid film flows over the stationary porous surface of the catcher. The catcher is positioned relative to the first path such that the liquid drops travelling along one of the first path and the second path contact the liquid film. | 02-02-2012 |
| 20120075389 | DROPLET GENERATOR - A method and device for passively periodically perturbing the flow field within a microfluidic device to cause regular droplet formation at high speed. | 03-29-2012 |
| 20120105553 | AQUEOUS INKJET PRINTING FLUID COMPOSITIONS - An aqueous inkjet printing fluid composition for use in an inkjet printer comprising a silicon-based material which contacts the aqueous printing fluid composition, comprising in a concentration sufficient to inhibit corrosion of the silicon-based material when contacted by the aqueous printing fluid composition a soluble metal ligand complex of Formula (I): | 05-03-2012 |
| 20120281047 | CONTINUOUS INK-JET PRINTING DEVICE, WITH IMPROVED PRINT QUALITY AND AUTONOMY - A continuous ink-jet printer or a print head of such a printer which includes electrical means for compensating for mechanical crosstalk between adjacent stimulation chambers, where these means simultaneously with the transmission, to a stimulated chamber, of a stimulation pulse on a stimulation line send a pulse for compensating for mechanical crosstalk on each of the lines supplying an actuator for the chamber adjacent to the stimulated chamber. Specific ratios between the peak amplitude of pulse for compensating for crosstalk and the peak voltage value of the stimulation pulse are provided as a function of the gaps between consecutive nozzles. | 11-08-2012 |
| 20130027478 | PIGMENTED INK JET INK COMPOSITION - 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. | 01-31-2013 |
| 20130083135 | CONDENSATION CONTROL IN AN INKJET PRINTING SYSTEM - Inkjet printing systems are provided. One inkjet printing system has a plurality of inkjet printheads, each having nozzles for jetting ink droplets having a vaporizable carrier fluid, a support structure to which the plurality of inkjet printheads are mounted, such that a face of each of the printheads of the plurality of printheads is positioned to jet the ink droplets toward a target area through which a receiver transport system moves a receiver during printing; and a shield between the support structure and the target area creating a first region between the shield and the target area with the shield having at least one opening through the shield through which the nozzles of the printhead can jet the ink droplets to the target area. An energy source supplies energy to cause the temperature of the shield to rise above a condensation temperature of vaporized carrier fluid in the second region. | 04-04-2013 |
| 20130093819 | LIQUID EJECTION HEAD AND LIQUID EJECTION APPARATUS - Provided is a continuous liquid ejection head that collects droplets which are not used for printing (unused droplets) without affecting the flight of droplets which are used for printing (used droplets). An ejection nozzle ( | 04-18-2013 |
| 20130120507 | INK DROPLET GENERATION MODULE - An ink droplet generation module for a print head assembly for a continuous ink jet printer, the printer having an ink supply system, a control system and a power supply system. The ink droplet generation module includes a supporting plate, an ink droplet generator, a charge electrode assembly, deflector plates, a phase measurement assembly, and a gutter tube, all attached to the supporting plate. | 05-16-2013 |
| 20140292951 | INKJET RECEIVER PRECOATS INCORPORATING SILICA - An inkjet receiving media comprising a substrate having a transparent topmost layer coated thereon at solid content of from 0.3 to 2.5 g/m | 10-02-2014 |
| 20160083604 | WHITE INKJET INK PRINTING - An inkjet printing method includes the steps of: a) printing a first print job by jetting a free radical UV curable white inkjet ink from a white ink print head and one or more free radical UV curable colour inkjet inks from one or more other print heads in a UV curable inkjet printer; b) filling the white ink print head in the UV curable inkjet printer with a safeguard liquid including one or more free radical polymerizable monomers; c) printing a second print job employing only the one or more other print heads in the UV curable inkjet printer for jetting one or more free radical UV curable colour inkjet inks; d) replacing the safeguard liquid of the white ink print head in the UV curable inkjet printer by UV curable white inkjet ink; and e) printing a third print job by jetting free radical UV curable white inkjet ink from the white ink print head and jetting one or more free radical UV curable colour inkjet inks from one or more other print heads in the UV curable inkjet printer. | 03-24-2016 |
