20100165024 | INK JET PRINTER AND METHOD FOR DEPOSITING A PROTECTIVE LAYER ON A SUBSTRATE - A protective layer is applied to a substrate moving relative to an ink jet nozzle array. Each nozzle responds to a piezoelectric actuator. Shapes of ink droplets deposited by the nozzles on the substrate, to form the protective layer, are controlled by shapes of electric waveforms applied to the actuators. Shapes of the waveforms respond to at least one of: droplet viscosity and temperature, temperature of the substrate, desired thickness of the layer, type of substrate surface to which the droplets are applied, and relative speed of the substrate and the ink jet nozzle array. | 07-01-2010 |
20100166975 | INK-JET PRINTER INK - Ink deposited on a substrate by an ink-jet arrangement to form a protective layer includes hardenable oligomer, hardenable monomer selected from a group including alkoxylated and/or poly-alkoxylated acrylic monomers comprising one or more di- or tri-acrylates, and a photoinitiator. The oligomer has a room temperature viscosity greater than 1 Pa·s. The oligomer to monomer weight ratio is between 1/6 and 1/25. The ink has a room temperature viscosity between 15 and 22 mPa·s and between 5 and 2 mPa·s at 60° C., and a room temperature surface tension between 15 and 28 mN/m. The photoinitiator is activated by a UV source having an appropriate wavelength and intensity. | 07-01-2010 |

20150083006 | DEVICE FOR CONTROLLING THE DEPOSITION OF COLOURED SUBSTANCE(S) AND OF WETTING SOLUTION FOR AN OFFSET PRINTING SYSTEM AND METHOD FOR IMPLEMENTING THE DEVICE - The present invention relates to a substance(s) deposition control device for an offset printing system, characterized in that it comprises:—at least one offset plate intended to receive a wetting liquid and a coloured substance in succession,—at least one controlled-deposition means for each offset plate, the deposition means comprising at least one deposition head spraying at least one wetting solution and at least one deposition head spraying a defined coloured substance,—at least one means for cleaning the offset plate, and in that the covering of the offset plate or plates comprises a mesh structure defined by a plurality of hydrophilic and lipophilic individual surfaces capable of receiving a controlled deposition of wetting liquid and/or coloured substance, each of these hydrophilic and lipophilic surfaces being separated from its direct neighbours by at least one hydrophobic and lipophobic peripheral surface. | 03-26-2015 |
20150085007 | METHOD FOR CHECKING THE ALIGNMENT OF PRINT HEADS AND ASSOCIATED ALIGNMENT METHOD - The aim of the present invention is to propose a method for assessing and correcting the alignment of print heads carried out using at least one linear adjustment algorithm, allowing greater accuracy in the use of same by eliminating inaccuracies linked to the ejection of drops from the print heads, while limiting the use of the resources of the IT system on which the method is used. Moreover, the number of print heads of which the alignment needs to be assessed and optionally corrected has very little influence on the overall processing time required by said method. | 03-26-2015 |
