Abstract

L'invention concerne un organe flexible à utiliser dans la fabrication d'une plaque d'impression lithographique. Selon l'invention, l'organe est formé en un substrat 12 en un métal en feuille ayant une flexibilité suffisante pour lui permettre d'être fixé au cylindre d'une presse d'impression, la plaque ayant un revêtement pulvérisé à haute fréquence 14 en un matériau photoconducteur qui a une forte efficacité quantique des photons, qui est microcristallin, totalement inorganique, flexible et qui peut être imagé par une technique électrostatique comprenant une charge, une exposition et un virage. Les parties virées 16 et les parties non virées 18 sont rendues respectivement hydrophobes et hydrophiles par des procédés appropriés. Les parties hydrophobes sont oléophiles et les parties hydrophiles sont oléophobes. L'invention s'applique notamment à la lithographie.A flexible member for use in the manufacture of a lithographic printing plate is disclosed. According to the invention, the member is formed of a sheet metal substrate 12 having sufficient flexibility to enable it to be attached to the cylinder of a printing press, the plate having a high frequency spray coating 14. made of a photoconductive material which has high quantum photon efficiency, which is microcrystalline, completely inorganic, flexible and which can be imaged by an electrostatic technique including charging, exposure and toning. The toned portions 16 and the untreated portions 18 are rendered hydrophobic and hydrophilic, respectively, by suitable methods. The hydrophobic parts are oleophilic and the hydrophilic parts are oleophobic. The invention applies in particular to lithography.
