Methods and apparatuses are provided for depositing a material on a surface. In accordance with the method a stream of a component material is formed having formed printing and non-printing droplets and satellite droplets of the material. The stream is directed at the surface. A deflecting energy is applied to separate printing droplets from non-printing droplets in the stream, so that only printing droplets travel to the surface. The deflecting energy is adapted to direct non-printing droplets for non-printing drop collection, and to direct at least a portion of the satellite droplets to be controlled in a manner adapted to prevent the material in the satellite droplets from reaching the surface, so that less than all of the material in the satellite droplets reaches the surface. Articles are also provided having limited satellite material.

Methods and apparatuses for forming an article

A method for manufacturing an optical compensator () on a transitional substrate () comprises applying a first orientation layer () to the transitional substrate. The first orientation layer () is then aligned and a first anisotropic liquid crystal material () is applied on the first orientation layer. In one embodiment, a retardation layer () is located between the transitional substrate () and the first orientation layer ().

Method for manufacturing an optical compensator on a transitional substrate

A process for making an optical compensator, comprising the steps of coating a orientable resin in a solvent onto a support; drying the resin-containing coating; orienting the resin-containing layer in a predetermined direction; coating a nematic liquid-crystal compound in a solvent carrier onto the orientation layer; drying the nematic liquid-crystal-containing coating; thermally treating the nematic liquid-crystal compound layer, cooling the nematic liquid-crystal compound layer, polymerizing or curing the anisotropic nematic liquid-crystalline layer to form an integral component; and optionally repeating the above steps on top of the integral component so that the optical axis of the first anisotropic nematic liquid-crystal layer is positioned orthogonally relative to the respective optical axis of the second anisotropic nematic liquid-crystal layer about an axis perpendicular to the plane of the support.

Process for making an optical compensator film comprising an anisotropic nematic liquid crystal

A process for making an optical compensator comprising the steps of coating a photo-alignable resin in a solvent onto a substrate; drying the resin-containing coating to form a orientable layer; heat treating the orientable layer before and/or after orientation, orienting the orientable layer in a predetermined direction; coating an anisotropic liquid crystal compound in a solvent carrier onto the orientation layer; drying the anisotropic layer. In a preferred embodiment, these steps are repeated so that the optical axis of a first anisotropic layer is positioned orthogonally relative to the respective optical axis of a second anisotropic layer about an axis perpendicular to the plane of the substrate.
