TRANSPARENT PRINTING BLANKETS AND METHODS OF USE

摘要

Substantially transparent printing blankets are provided comprising a substantially transparent printing layer (11) disposed upon a substantially transparent support layer (12). The substantial transparency of such printing blankets permits off press introduction of knock-out areas. In certain embodiments, this is accomplished by disposing t he support layer (12) of the printing blanket adjacent to a substrate which bears either an image to be printed or some other print transfer information (such as a negative) corresponding to the image. The print transfer information then is viewed through the printing blacket to identify portions of the underlying substrate which bear information indicating that the print should not appear on a corresponding portion of the coated substrate. After such portions are identified, the printing layer (11) is removed from the support layer (12) i n those areas of the printing blanket which are adjacent to the identified portions of the substrate.
