摘要： The invention relates to continuous ink jet printing of an aqueous pigmented ink composition recycled from a main ink supply reservoir, employing a printer with a fluid delivery system capable of measuring the ink electrical resistivity, and providing needed quantities of either vehicle replenisher fluid or fresh ink to maintain the desired recycled ink concentration. The electrical resistivity of the pigmented ink can be modified advantageously for stable ink recycling by the addition of the organic amine salt of an acid, and the pH stability of the ink can be simultaneously improved by the additional inclusion of the neutral form of the organic amine in similar molar proportions to the amine salt. The pigmented ink jet ink compositions provide for particularly stable and invariant fluid properties during periods of extended printer operation and ink recirculation.

摘要： An electronic printing system comprises a substrate supply for supplying a substrate along a paper path configured in an arc. The substrate is controllably transported through the electronic printing system past a plurality of printheads. The printheads are arranged above the paper path, in an arc configuration corresponding to the paper path configuration. As the substrate passes under each printhead, a printed image is generated on the substrate. A plurality of rollers are arranged to have at least one roller under the substrate at each location corresponding to a printhead location. Finally, a dryer is located after the last of the plurality of printheads for fixing the printed image to the substrate.

摘要： A cleaning system for ink jet printing orifices includes cooperative elements which provide varying pressure differentials across the orifice plate that oscillate ink into and out of the orifices. In one embodiment the pressure differentials are implemented by varying the impedance to ink cross-flow through a print head cavity while pressurizing a region around the exterior of the orifices.

摘要： The present invention relates to ink output in ink jet printing systems. A refractometer is used to control the concentration of inks used in continuous ink jet printers. A concentration detector measures the total amount of light reflected from a surface. Changes in the ink cause a definite change in sensor output. As the refractive index is changed, shifting the critical angle for internal reflection, more or less light is reflected to the sensor. The index of refraction can be determined from the sensor once corrections are made to account for temperature dependencies of the sensor and light source and baseline measurement of reflected light amplitude. These dependencies are carried out in the refractometer.
