    摘要： Provided is an inkjet composition for printing an indelible colorant onto a substrate. Also provided is a method of printing using the inkjet composition, and a printed substrate obtainable and obtained from the method of printing. The inkjet composition has an indelible colorant, one or more solvents, and a binder. The migration distance of the indelible colorant in the substrate is less than 0.85 mm after 7 days at 25° C. The composition may be used to provide indelible markings in the surface of the substrate, and these markings do not significantly disperse over time.

    摘要： Method and Apparatus for Reducing Ink Foaming in a Continuous Inkjet Printer The invention provides a method of and apparatus for reducing foam formation in the returned ink in a continuous inkjet printer. The returned ink is subjected to deceleration and is reduced in pressure, preferably by being directed into a sub-chamber which reverses the direction of flow and provides an elevated edge over which the ink overflows. The de-aeration facility is preferably incorporated in an ink service module.

    摘要： A pump (1) has a rotor (4) and a stator (3) disposed closely adjacent to and biased towards it, but spaced apart from a surface of the rotor. The stator (3) or rotor (4) has recesses (30) on its surface facing the rotor or stator respectively, and an inlet to and an outlet from each recess to provide for the supply of fluid to and from the recess. Rotation of the rotor (4) about its axis is arranged to cause fluid to be pumped from the inlet to the outlet as a result of the viscous drag on the fluid resulting from rotation of the rotor relative to the stator (3). The force biasing the rotor (4) and stator (3) together is provided at least in part by fluid pressure feedback from the pump (1) in order to control the clamping or biasing pressure between the rotor and stator automatically.

    摘要： A two-stage pump (9) for a continuous ink jet printing system comprises a first stage (A) which includes a chamber (91,92) having an inlet (93) and an outlet (94) via a non-return valve (115) to a channel (95). The first stage chamber (91,92) is divided by a dished diaphragm (101) movable by a first cylinder (97) mounted on a pump shaft (98). The pump (9) has a second stage (B) comprising a chamber (104,105) having an inlet (106) from the channel (95) and an outlet (107). The second stage chamber (104,105) is divided by a rolling diaphragm (116) movable by a second cylinder (108) mounted on a pump shaft (98). The cylinders (97,108) are arranged to be driven, and thus drive their respective diaphragms (101,116), 180.degree. out of phase so that ink and air enters the first stage chamber (91,92), is pressurised by the first cylinder (97) and passed through the channel (95) to the second stage chamber, and is further pressurised and passed out of the outlet (107) of the second stage chamber (104,105).
