    • On-press development of an imaged printing plate on a plate cylinder, in which ink is applied by an ink form roll, a blanket roll is in contact with the plate, a rubber roll is opposed to the blanket roll, and printable media passes between the blanket roll and the rubber roll. The plate comprises a substrate carrying an imaged coating, in which nonimage areas have cohesion C1, adhesion to the substrate A1, and adhesion to the applied ink A3 and image areas have cohesion C2, adhesion to the substrate A2, and adhesion to the applied ink A4. The ink has cohesion C3 and adhesion A5 to the blanket roll. The nonimage areas have adhesion A6 to the printable medium and the ink has adhesion A7 to the medium. The adhesions and cohesions are such that the blanket roll pulls the ink from the plate and the ink pulls the nonimage areas from the substrate as undissolved particles that are transferred by the blanket with the ink to the printable media.

    • Excellent development of planographic printing plates can be achieved by exposing an imaged, negative working, photopolymerizable coating to a high pressure stream of essentially untreated tap water, whereby the water completely removes only the less cohesive and adhesive (e.g., partially polymerized) regions to the substrate, thereby directly producing a printing plate having an image pattern of highly cohesive and adhesive, oleophilic regions of the coating and hydrophilic regions of the substrate. The coating removal mechanism appears to be due entirely to ablation. The high pressure stream is preferably delivered to the plate through at least one nozzle having a discharge pressure greater than about 200 psi. Each nozzle preferably has a spray pattern that impinges the plate over a substantially rectangular region of the plate, and the nozzle and plate translate relative to each other. The nozzle can reciprocate across the width of a longitudinally transported plate, thereby contacting successive regions of the plate in a rastering fashion.
    • 平版印刷版的优异发展可以通过将成像的,负性的可光聚合涂层暴露于基本上未处理的自来水的高压流中,由此水完全除去较少的内聚力和粘合剂(例如,部分聚合的)区域 从而直接制造具有高度粘合和粘合的图像图案的印刷版,涂层的亲油区域和基底的亲水区域。 涂层去除机制似乎完全归因于消融。 高压流优选通过具有大于约200psi的排出压力的至少一个喷嘴输送到板。 每个喷嘴优选地具有将板撞击在板的基本矩形区域上的喷射图案,并且喷嘴和板相对于彼此平移。 喷嘴可以横跨纵向传送的板的宽度往复运动,从而以划痕方式接触板的连续区域。

    • The invention relates to the application of a uniform film of a fluid to the surface of a flat workpiece as it is being conveyed through a workstation. The invention is specifically directed to the development of lithographic printing plates and comprises the application of the thin film of developer solution to each plate in a controlled manner using a wire-wound coating device and a unique manner of metering and feeding fresh fluid to the wire-wound device. Specifically, the fluid is gently fed onto the wire-wound device by simple volumetric displacement and overflow from the inside of a hollow tube onto the wire and the flow is controlled by sensing the beginning and end of each workpiece or plate. The hollow tube may be the wire-wound component or it may be a tube mounted above the wire-wound component.
    • 本发明涉及在通过工作站输送时将流体的均匀膜应用于平坦工件的表面。 本发明特别针对平版印刷版的开发,并且包括使用绕线涂布装置以可控的方式将显影剂溶液的薄膜施加到每个印版上,以及将新鲜流体计量并输送到线材的独特方式 缠绕装置。 具体地说,流体通过简单的体积位移被轻轻地馈送到绕线装置上,并且从中空管的内部溢出到线上,并且通过感测每个工件或板的开始和结束来控制流动。 中空管可以是绕线部件,也可以是安装在绕线部件上方的管。

    • A lithographic printing plate substrate web is brush grained with some of the brushes having the bristles moving over the web along a first track and some additional brushes having the bristles moving over the web along a second track at an angle of at least 5null to the first track. Some of the brushes may have the axis of rotation perpendicular to the direction of movement of the web in the conventional manner and at least one additional brush having the axis of rotation at an angle to the direction of movement of the web. There may be a plurality of such additional brushes, usually two, with the additional brushes being angled with respect to each other. In one embodiment, the bristles of the additional brush track over the web in a direction perpendicular to the web movement. Subsequent to brush graining, the brush grained surface is electrochemically grained.
