Title
(EN) PRINTING FORM PRECURSOR AND METHOD OF PRINTING
(FR) AMÉLIORATIONS CONCERNANT L'IMPRESSION
Abstract
(EN) A printing form precursor comprises a printing surface which comprises an anodic layer which is hydrophobic and capable of being made hydrophilic by fast laser pulses but capable of becoming hydrophobic again, preferably for re-use, if desired. These changes are influenced by thickness of the anodic layer, and by alloying elements in the anodic layer. Benefit is gained also from using a darkly coloured anodic layer and by permitting the change from hydrophilic to hydrophobic to take place in a carbonaceous or siliceous atmosphere. By such means the invention achieves the goal of providing a printing form precursor which does not need a chemical developer, and which can be used multiple times, to print different images.
(FR) Un précurseur de forme d'impression comprend une surface d'impression comprenant elle-même une couche d'anode qui est hydrophobe et capable de devenir hydrophile sous l'effet d'impulsions laser rapides, puis de redevenir hydrophobe si souhaité, de préférence en vue de sa réutilisation. Ces changements sont influencés par l'épaisseur de la couche d'anode et par la présence d'éléments alliés dans la couche d'anode. Est également avantageux l'emploi d'une couche d'anode de couleur sombre et le passage permis d'un état hydrophobe à un état hydrophile dans une atmosphère carbonée ou siliceuse. Ces moyens permettent à l'invention d'atteindre son objectif, qui est de fournir un précurseur de forme d'impression ne nécessitant pas de révélateur et pouvant être utilisé de multiples fois pour l'impression d'images différentes.
