摘要： An ink transfer printing devide in which ink transfer is controlled by a viscosity change in ink includes an ink reservoir (2) for retaining ink held under pressure. The ink reservoir (2) is associated with an ink transfer surface (4) which has a plurality of perforations (6). Under ambient conditions, the viscosity of the ink prevents flow of the ink through the perforations (6). The ink transfer printing device also includes a viscosity control unit (8, 20, 25, 26, 32, 38, 42, 46) for inducing a change in the viscosity of the ink near certain perforations thereby enabling a controlled amount of the ink near each of these certain perforations (6) to flow through these certain perforations to an outer surface of the ink transfer surface (4). Techniques for controlling the ink dot size using concentric regions (72, 74, 76, 78, 80, 82) about each of the perforations (6) are disclosed. The ink which has flowed onto the outer surface can then be transferred to an intermediate surface (54) or a printing media (10). A method for viscosity-driven ink transfer printing is also disclosed. The present invention enables a printer, a copier, or the like to provide low cost, high speed, high resolution printed images.

摘要： A special ink (26) consists of water and a humectant. A reusable paper (10) includes a surface (14) darkened by a water-insoluble material and a coating (16) covering the darkened surface (14). The coating (16) is made of a material that scatters light when dry and that becomes at least translucent when wetted by water. If the special ink (26) is used to print on the reusable paper (10), the print will be visible for a limited period of time (e.g., half an hour). By the end of that time period, however, the special ink will have evaporated and the print will have disappeared completely from the reusable paper (10). The special ink (26) may be applied to the reusable paper (10) by an inkjet printer (20). An inkjet cartridge (28) for such a printer (20) includes a casing (24) filled with the special ink (26).

摘要： A sheet of paper, such as a form, is provided with a surface conductive trace (102) which can be coupled to an electronic measurement circuit (400). A measure of the conductivity of the trace (104) gives an indication of the type of the sheet. The sheets (202, 204) of a stack (200) of sheets can be identified by having different conductive traces (102) thereon. A sheet support board (400) carries conductive pads (402, 404) which couple the traces (100) to the measurement circuit.

摘要： Substantially homogeneous solid ink-jet compositions are disclosed. The use of such compositions with colored transparencies substantially reduces the level of light scattering as compared to the level of light scattering arising from the use of non-homogeneous ink-jet ink compositions. It is also disclosed that further improvements in the ink-jet composition can be achieved by employing a cosolvent in the composition.
