Abstract: A method for providing a lithographic printing plate includes developing an exposed imageable element with an alkali silicate-containing developer composition having a pH of at least 12.0. The developer composition is regenerated by adding to it an alkali silicate-containing regenerator composition having a pH of at least 12.0. Conductivity of both the developer and regenerator compositions is suppressed from the presence of one or more conductivity reducing agents (such as glycerin). This conductivity suppression in the developer composition is greater than the suppression of the conductivity of the regenerator composition.

The radiation-sensitive composition can be used to prepare a negative-working imageable element that is sensitive to suitable imaging infrared radiation, can be imaged at relatively low energy, and can be developed either on-press or off-press.

Abstract: Rapid heating of a lithographic printing plate is achieved by feeding the printing plate along a substantially curved path that is adjacent to one or more curved pads of an air bearing that is pressurized with heated air. The one or more curved pads are constructed such that the substantially curved path is curved with an axis of curvature substantially perpendicular to the feed direction of the printing plate. The plate is additionally elastically bent to follow and conform to the substantially curved path. The substantially curved path minimizes printing plate distortion during heating, and thus prevents the plate from being damaged from contact with any of the one or more curved pads. The one or more curved pads are also arranged to allow for exceptionally good heat transfer characteristics and thus more effective plate heating.
