It is customary in commerical printing practice to use direct mode lithographic printing techniques for work having limited image quality requirements and to use offset mode lithography for work having the highest print quality requirements. Disclosed is a method of preparing a conformable two-fluid printing master capable of producing prints by direct lithographic procedures which are equal in quality to those customarily produced by the more complex offset lithographic procedures. A hydrophobic, conformable elastomeric film is rendered hydrophilic by the attach-ment of a thin surface layer of finely divided particles of, for example, aluminum, copper, and fumed silica. Such a surface also provides adhesive properties enabling the attachment of a variety of imaging materials such as, for example, xerographic toner, which are hydrophobic.
