    摘要： A method for increasing the diameter of an ink jet ink dot resulting from the application of an ink jet ink drop applied to the surface of an ink jet recording medium having a support having thereon an image-receiving layer, the image-receiving layer containing: a) from about 20 to about 65% by volume of particles; b) from about 25 to about 70% by volume of a polymeric binder; and c) up to about 10% by volume of a cross-linking agent; the method comprising applying the ink jet ink drop on the surface of the image-receiving layer whereby the diameter of the ink jet ink dot is increased relative to that which would have been obtained if the image-receiving layer had greater than about 65% by volume of particles.

    摘要： An apparatus and method of bead coating a web using a coating die. The method comprises forming one or more layers of coating material using the coating die and allowing the one or more layers to impinge on the web as the web and die move relative to each other. The web surface has an average peak to peak roughness as defined by DIN 4768, ISO4287 or BS1134 between 2 &mgr;m and 20 &mgr;m. The layer of coating material forming a wetting layer adjacent to the web has a viscosity of between 35 mPas and 200 mPas measured at a shear rate of substantially 10,000 s−1. An electrostatic field is provided at the point at which the layers impinge on the web to stabilize the layers of coating material. The method enables the web being coated to be conveyed at a speed greater than 400 cm/s relative to the coating die whilst avoiding the problem of air entrainment.

    摘要： A method of creating substantially monodisperse droplets comprising supplying a first fluid (1) and a second immiscible fluid (2) within a set of channels, the second fluid surrounding the first fluid and filling the channels to form a composite jet. The composite jet passes through an entrance channel (4) into a wider cavity (3), where the first fluid breaks into droplets (5), the resulting composite of droplets of the first fluid within the second fluid passing through an exit channel (6). The cross sectional area of the exit channel perpendicular to the flow is smaller than the cross sectional area of the cavity and the passage of a droplet of the first fluid out of the cavity via the exit perturbs the composite flow field within the cavity such that the incoming jet of the first fluid is perturbed.

The present invention limits the magnitude of flow induced noise generated by particulate components in the ink to maximize the efficiency of drop formation and to minimize adverse interactions with the nozzle.
