Abstract: A method for selective processing of a panel, the method may include receiving a panel that has a bottom side and a top side and comprises a first group of drilled holes and a second group of drilled holes; at least partially sealing a bottom of any through hole of the first group; filling, by a selective filing process, any drilled hole of the first group that has a top opening to provide at least partially filled drilled holes of the first group without filling the second group of drilled holes; and plugging, by a selective plugging process, a top of any drilled hole of the first group.

Abstract: Flexographic printing precursors are prepared by providing an elastomeric mixture of one or more elastomeric resins and non-metallic fibers having an average length of at least 0.1 mm and an average diameter of at least 1 ?m, and adding a vulcanizing composition and optional other components to the elastomeric mixture. The elastomeric mixture is then mechanically treated to orient the non-metallic fibers predominantly in the same dimension in the elastomeric mixture. It is then vulcanized and formed into a laser-engraveable layer having two orthogonal dimensions. The non-metallic fibers are predominantly oriented in one of the two orthogonal dimensions.

Abstract: A laser imageable flexographic printing plate precursor comprises a thermoset elastomeric upper layer that is at least partially ablatable and comprises a radiation sensitive compound, and a non-ablatable elastomeric underlayer. This flexographic printing plate precursor can be imaged to provide a printing plate that is primarily useful for “high quality” printing because the resulting relief image is generally not greater than 600 ?m and has an extremely even “floor”. The imaged flexographic printing plate also can have a high visual contrast between the imaged areas and the non-imaged background areas.

Abstract: The present invention provides a method of preventing pigment agglomeration upon the addition of an aqueous resin solution to an aqueous pigment dispersion. The present invention further provides a method of stabilizing a pigment dispersion upon the addition of an aqueous resin solution to an aqueous pigment dispersion. Pigment agglomeration is prevented and the pigment dispersion is stabilized by mixing butylated PVP with the pigment dispersion prior to the addition of the resin solution. The present invention further provides an aqueous ink-jet composition for use in aqueous-based ink-jet printers. The composition comprises water, butylated PVP, an aqueous pigment dispersion, a resin and a humectant. The present invention further provides a process for preparing said ink composition.

Abstract: A clog-free jettable fluid composition and a method for producing the same are provided. According to some embodiments of the present invention, the jettable fluid comprises water as solvent, a resin-in-aqueous-emulsion having an acid number of at least 30, and an alkaline agent. The jettable fluid has a pH above 9.
