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.

摘要： Reusable lithographic printing members are prepared from a ceramic that is a composite of a zirconia alloy and .alpha.-alumina. In use, a printing surface of the zirconia-alumina composite ceramic is imagewise exposed to electromagnetic radiation such as from a laser under controlled conditions to provide localized "melting" of the zirconia alloy in the exposed areas. Those areas are transformed from a hydrophilic to an oleophilic state or from an oleophilic to a hydrophilic state, thereby creating a lithographic printing surface that 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 substrate in lithographic printing. The printing members are directly laser-imageable as well as image erasable, and can include printing plates, printing cylinders, printing tapes and printing sleeves.

摘要： An improved die retaining element has a highly efficient, durable and wear and abrasion resistant flange portion surrounding an opening for securing a die mold therein. The flange portion may have practically any geometric configuration, such as round, but is most effective when in a continuous plane with the powder feed box in sliding contact with a feed box. In particular, the flange portion may selectively have either a high precision tetragonal zirconia polycrystal (TZP) ceramic or zirconia-alumina ceramic composite, depending on the surface material of the feeder box in sliding contact therewith. In one embodiment, the flange portion has tetragonal zirconia polycrystal ceramic and the feeder box has zirconia-alumina ceramic composite sliding surface. In another embodiment, flange portion has a zirconium-alumina ceramic composite sliding portion and the feeder box has a tetragonal zirconia polycrystal ceramic sliding portion.

摘要： Rotary lithographic printing members are prepared from a non-porous zirconia ceramic that is an alloy of ZrO.sub.2 and a second oxide chosen from MgO, CaO, Y.sub.2 O.sub.3, Sc.sub.2 O.sub.3, a rare earth oxide or a combination of any of these. These printing members can be rotary printing cylinders having a zirconia alloy ceramic printing surface. Such cylinders can be composed of zirconia alloy ceramic throughout, or have a ceramic sleeve or shell mounted around a non-ceramic core. In use, the surface of the zirconia alloy ceramic printing member is imagewise exposed to infrared 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. These printing members are directly laser-imageable as well as image erasable.
