International Classification:

G03G 1310

US Classification:

430100

Abstract:

Process for reversal development of a latent electrostatic image in a layer on a conductive support by developing with an electrostatic developer having electrostatically charged toner particles by (a) generating imagewise areas in the layer having different rates of charge decay and/or charge acceptance, (b) charging the layer, (c) allowing formation of an electrostatic image corresponding to the imagewise generated areas by differential charge decay and/or charge acceptance, (d) creating an electrical field to attract toner particles preferentially to the areas of lesser charge, and (e) developing the areas of lesser charge with electrostatically charged toner particles having the same polarity as that of the charged layer. The developed image can be transferred to a receptor surface, e. g. , paper. The process is useful with many type photosensitive masters in preparing reversal images with the use of only one master, toner and film original.

Abstract:

Aspects of the present application relate to systems and methods for automated web-based filter tuning. The method can include receiving information characterizing a plurality of attributes of a web server and normalizing the received information. The method can include identifying a set of relevant tags to the web server via comparison of the normalized received information to data contained in a tag database, and forming a set of signatures relevant to the web server based at least in part on the set of relevant tags. The method can include receiving an administrator selection of at least some of the set of signatures, enabling the selected at least some of the set of signatures for filtering of received web requests.
