Abstract
PURPOSE:To produce a porous film having an excellent dimensional characteristic by utilizing improved photomechanical technique and electrocasting method at the time of producing the porous film to be used for the printing part of a printing machine, etc. CONSTITUTION:The thin sheet material of a Be-Cu alloy is oxidized in the air, for example, at 200 deg.C for 30min to form a releasing layer, and a solvent-type dry film is adhered to the back to protect the back. A resist film 2 is then formed on a Be-Cu metallic thin sheet 1, a plating 4 is formed in 6mum thickness on one side with respect to the specified diameter 3 of 15mum of the electrocast thin sheet metal 10, pores having an outer diameter S of 27mum are photographically produced with a pitch 6 of 50mum and a gap 7 of 23mum, and a glass original plate for exposure is obtained. The plate is brought into contact with the metallic sheet 1, vacuumexposed, developed, and fixed. The sheet is then electrocast in an electrocasting bath consisting of an Ni anode 8, a cathode of the metallic sheet 1, and a plating bath 9, the electrocast layer is locally released, the electrocast layer can be released to the opposite side while bending the metallic sheet, and a porous film having excellent dimensional characteristics such as thickness, pitch, and pore diameter is produced.
