The aim of the invention is to produce a type of print which can be erased, selectively washed or cleaned, plasticized without handling via means of telecommunication, existing networks, and improving its physical or computer preservation. The print is produced on a substrate provided with a hydrophile coating, this substrate being made of a natural cellulose material or of a synthetic material, said substrate being impermeable, smooth or microporous in several degrees. It is a substrate on which it is possible to print, write, draw or reproduce and subsequently erase, correct, clean, totally or partially, dry, with water or chemical solvents or with hydrocarbons, relatively or absolutely and selectively. One or two printing levels can be used. The substrates having a hydrophile coating will, after printing, be coated with an impermeable transparent plastic film. These methods can be implemented and operated on communication networks already in existence or to be created.

La présente invention ayant pour but de réaliser une impression effaçable, indélébile ou nettoyable sélectivement, plastifiable sans manipulation via les outils de télécommunication, les réseaux existants, et permettant d'en accroître la conservation physique ou informatique. L'impression étant réalisée sur un substrat pouvant être pourvu d'un revêtement hydrophile, ce substrat étant fabriqué à partir d'une matière cellulosique naturelle ou d'une matière synthétique, ledit substrat étant de nature imperméable, lisse ou microporeuse selon plusieurs degrés. Substrat sur lequel il sera possible d'imprimer, d'écrire, de dessiner ou de reproduire et de pouvoir ensuite effacer, corriger, nettoyer, en totalité ou de façon partielle, à sec, à l'eau, aux solvants chimiques ou aux hydrocarbures, et ce de façon relative ou absolue et sélectivement. On pourra utiliser un ou deux niveaux d'impression. Les substrats possédant un revêtement hydrophile seront recouverts après impression par un revêtement transparent imperméable de type plastique. Ces procédés pouvant être mis en oeuvre et exploités à partir des réseaux communicants existants ou à créer.
