			photogravure       St. Anastasia cathedral - Verona Reproduction from a vintage Albumen photograph of 1870 Heliogravure au grain – 16 x 20,5 cm. - 1990
	héliogravure            Either you have to reproduce a drawing, a painting, a picture, or a place; a person or an happening, all these will first be photographed. From the negative it will be obtained a suitable positive film (same size of the final print) through which the image is transferred onto the metallic plate. It happens using a gelatinized paper (tissue paper). Through the bitumen photogravure, sketches or drawings can be reproduced as good help or complement to further manual actions on the plate. Even re-graining and re-etching are easy and satisfactory because the new graining overlap an identical texture.      Originals produced with pictorial techniques – untranslatable through the traditional etching tools - can be reproduced very accurately. It means watercolour, oil, charcoal, …, or lithographs, silk-screens, etchings, of which the original matrix has been lost, destroied or simply exausted. The total run from a gravure on copper is roughly 120 copies, that can be doubled with a previous ‘steeling’ of the printing surface.
