    摘要： Various processes for enhancing the contrast between image and non-image regions of a printed image are implemented by increasing the toner-accepting charge on the surface of a printing form having a ferroelectric layer and from which the image is printed. The increase in charge is achieved, in alternate forms of the inventive process, either by increasing the temperature of the printing form surface relative to the temperature at which the form has been polarized, or by mechanically loading the printing form carrying cylinder for transfer of the toner from the printing form, or by applying additional charge carriers to the entire surface of the printing form (30) so as to create an enhanced potential difference between positively-polarized regions and negatively-polarized regions and, thereby, increased contrast between image and non-image regions.

    摘要： This invention relates to an improvement in the process for the preparation of printing forms and/or metallized images by electrostatic charging, exposing, and treating with a toner of a photoconductor layer applied to an electrically conductive support material, and removing the photoconductor layer in the non-image areas, the improvement which comprises effecting removal of the toner-free photoconductor layer by transferring it at a temperature in the range of about 50.degree. to 250.degree. C. to a receiving material which has a greater surface adhesion to the photoconductor layer than does the electrically conductive support material.

    摘要： A duplicating master is produced from which multiple copies of an original may be made by first making a direct electrophotographic copy of the original. Thereafter, through the use of heat, the image portions of the electrophotographic copy are transferred to a transfer sheet. The transfer sheet with the image thereon, now constitutes a duplicating master and may be used as such.
