Improvements relating to electrophotography. |
摘要 |
<p>The invention provides a master for use in image transfer by contact printing onto a transparent electrophotographic (TEP) film, which comprises an electrically insulating substrate having a planar surface which carries image elements deposited thereon; and a thin transparent insulating layer covering said planar surface and said image elements. The surface of the thin transparent insulating material is preferably profiled so that it comprises a base level and raised portions extending above said base level, the area of the raised portions being small compared to the total surface area of the transparent insulating layer. A thin transparent electrode may be incorporated between the substrate and the thin transparent insulating layer.</p><p>Methods of forming such a master and of contact printing with it are also disclosed.</p> |
