PURPOSE:To provide a printing plate having the printing processing adapted to a fine image to be used in an electronic industry, by forming openings to a part of a metal membrane in pattern-wise manner and forming recessed picture lines demarcated by the peripheral side walls of the opening parts of the metal membrane. CONSTITUTION:A metal membrane 16 is adhered to a resin film or sheet 18 having flexibility through an adhesive 17 and a part of the metal membrane 16 is provided with openings in a pattern-wise manner and recessed picture lines 20 demarcated by the peripheral side walls 19 of the opening parts of the metal membrane 16 are formed to the metal membrane 16. The metal membrane 16 desirably has a thickness of 5-50mum, flexibility, strength and easy etching processability. The adhesive being used has a role not only fixing metal with resin but also displays printing pressure, therefore, it is preferable to have especially flexibility because said adhesive has to wind around a blanket cylinder. |
