Life of the patent
2 dated eventsAbstract
A reflective surface behind an image to be scanned on an optical image scanner, copier, facsimile machine or similar device. Preferably, the reflective surface has a reflectance less than 90% with a preferred reflectance range of 60% to 75%. This reflective surface is substantially integral with the scanner, copier or facsimile lid surface and substantially reduces image bleed-through while resulting in an acceptable level of color shift and an acceptable loss of dynamic range relative to a white surface. In a second embodiment, the reflective surface is interchangeable by the end user in order to optimize the reflectance of the reflective surface for any given document to be scanned, copied, or faxed.
