PURPOSE:To produce a picture film for photoengraving extremely easily and inexpensively by forming toner pictures on a light transmittable substrate having a toner-adhesive and ink-repellent surface. CONSTITUTION:A toner-adhesive and ink-repellent film layer (e.g.: a layer coated with the compsn. consisting essentially of the three components; org. polysiloxane, polar group-contg. alkoxysilane and metal-oxygen bond-contg. org. titanium or Zr compd.) is provided on a transparent substrate (e.g.; a substrate consisting of polyester, polyamide, PS, etc.) and the light transmittance thereof is controlled to >=50%. After toner pictures are fixed on such light transmittable substrate, the surface of the light transmittable substrate formed with the toner pictures is inked to increase the optical density in the toner picture parts on the surface of the light transmittable substrate selectively, whereby the picture film for photoengraving is obtained. According to this method, the picture film is produced extremely easily and inexpensively. |
