Anodized zirconium metal lithographic printing member and methods of use |
摘要 |
Long wearing and reusable lithographic printing members are prepared from a zirconium metal or alloy that has an anodized zirconium metal or alloy printing surface. In use, the anodized printing surface of the printing member is imagewise exposed to electromagnetic radiation which transforms it from a hydrophilic to an oleophilic state or from an oleophilic to a hydrophilic state, thereby creating a lithographic printing surface which is hydrophilic in non-image areas and is oleophilic and thus capable of accepting printing ink in image areas. Such inked areas can then be used to transfer an image to a suitable receiving material in lithographic printing. These printing members are directly laser-imageable as well as image erasable.
