摘要： A metal substrate is treated with a plurality of rotating brushes and a slurry of particulate material such that the treated surface is capable of absorbing incident infrared laser radiation. The substrate is itself capable of being visibly imaged by selective writing with an infrared laser. The substrate is coated with an ablatable coating which is transparent to the imaging infrared laser radiation. Selective exposure to infrared laser radiation ablates this coating in the laser exposed areas as a result of the absorption of infrared radiation by the substrate. The substrate can be anodized after rotary brush graining and still retain its ability to be imaged and ablate a coating. The coated article can be imaged in a computer-to-plate infrared laser imaging device. Depending on the specific coating and substrate selection, the imaged article can be used in a conventional lithographic printing process or in a dryographic printing process.

摘要翻译：用多个旋转刷和颗粒材料的浆料处理金属基底，使得经处理的表面能够吸收入射的红外激光辐射。衬底本身能够通过使用红外激光器的选择性写入而被可视地成像。衬底涂覆有对成像红外激光辐射透明的可烧蚀涂层。选择性地暴露在红外激光辐射下，由于衬底吸收了红外辐射，激光暴露区域中的这种涂层消失了。基材可以在旋转刷磨后进行阳极氧化，并且仍然保持其成像能力和烧蚀涂层。涂覆的制品可以在计算机对板红外激光成像装置中成像。根据具体的涂层和基底选择，成像的制品可以用于常规的平版印刷工艺或干涉印刷工艺中。

摘要： A positive-working, infrared imageable coating and a lithographic printing plate or other element with the coating are described. The coating is a phenolic resin containing an o-diazonaphthoquinone derivative which couples or reacts with the resin to partially insolubilize the coating and an infrared absorbing dye or pigment which further insolubilizes the coating and which renders the coating imageable by infrared radiation. The coating contains only that quantity of infrared radiation absorber necessary to be imageable and only that small quantity of o-diazonaphthoquinone derivative necessary to supplement the insolubilizing function of the absorber. Specifically, the absorber is from 1 to 10 weight percent of the total dry weight of the coating and the dry weight ratio of the absorber to the diazonaphthoquinone moiety is greater than 1:5 and preferably 1:2 or greater. By replacing a portion of expensive dye with some less expensive o-diazonaphthoquinone derivative to obtain the necessary degree of insolubility, the cost of the coating is greatly reduced.
摘要翻译：描述了正性工作的可红外成像涂层和平版印刷版或其它具有该涂层的元件。涂层是含有邻二氮萘醌衍生物的酚醛树脂，其与树脂偶联或反应以使涂层部分不溶化，并且红外线吸收染料或颜料进一步使涂层不溶化，并使涂层通过红外辐射成像。涂层仅含有可成像的那种量的红外辐射吸收剂，只有少量的补充吸收剂的不溶性功能所需的邻二氮萘醌衍生物。具体地，吸收剂为涂层总干重的1〜10重量％，吸收体与重氮萘醌部分的干重比大于1:5，优选为1或2以上。通过用一些较便宜的重氮萘醌衍生物代替一部分昂贵的染料以获得必需的不溶性，涂层的成本大大降低。

摘要： The water-loving properties of an anodized aluminum lithographic surface are enhanced or restored by treatment with a solution containing a monomeric, organo-phosphonic acid chelating compound or salt thereof. Such treatment can take place following, during or in lieu of the treatment of anodized aluminum in web form with an alkali metal silicate in the process of manufacturing printing plates. Alternatively, the treatment can be carried out as a plate is developed and/or prepared for the press. In a third approach, an organo-phosphonic acid chelating compound can be incorporated into a fountain solution, ink or correction fluid.

摘要： A coated lithographic printing plate comprises a grained, anodized aluminum substrate and coating thereon comprising a diazo resin in admixture with particulate energy absorbing material that will absorb incident radiation and re-radiate it as radiation that will change the diazo resin coating which is imageable with a Crosfield Datrax 760 YAG laser plate maker producing incident radiation of 1/06 microns. The topography of the substrate and the particulate material in the coating trap and convert a substantial portion of the incident laser radiation which passes through the coating without substantially affecting same into radiation that will change the coating.

摘要： A substrate is coated with a first material which is soluble in a first solvent, whereupon a second material which is strongly adherent to the first material and insoluble in the first solvent is selectively applied by an ink jet printer. The substrate is then developed in the first solvent to establish the image. In a preferred embodiment the substrate is hydrophilic, the first material is a negative working photosensitive material, and the second material is a transparent adhesive, which permits curing the first material by exposure to actinic light after the development step. The adhesive is then removed. In an embodiment directed to a waterless plate the substrate includes a surface coating of silicone, and the first material is a primer which promotes adhesion of a second material in the form of an oleophilic adhesive which is selectively applied. The primer is then developed to expose the silicone on the non-image areas. The ink carrying image areas are formed by the adhesive, which in this embodiment is not removed.

摘要： Anodizing current is prevented from being carried downstream by an aluminum web after anodizing in a continuous anodizing process. An anode is placed in a post-treatment cell containing an electrolyte which is electrically connected to a cathode in the anodizing cell via a source of DC current which is independent of the source of anodizing current. The web polarity is switched from positive to negative and a voltage greater than the exist voltage of the web is applied to prevent anodizing current from being carried downstream in the web after anodizing.

摘要： Process for making a lithographic printing plate having an oleophilic amplified image prepared by(a) providing a silicated aluminum substrate with a hydrophilic, anionic, negatively charged surface and a layer on said surface of a light sensitive, cationic, positively charged, water soluble diazonium material having at least two reactive sites per molecule, each reactive site being capable of being chemically altered by actinic light or chemically reacted with an anionic material;(b) selectively and incompletely exposing the diazo layer to actinic light to alter only a portion of the reactive sites thereby adhering the diazo material to the substrate in the exposed areas;(c) coupling the diazo layer with an anionic material to reinforce diazo in the exposed areas in situ and remove diazo from the unexposed areas by contacting the substrate after exposure with an anionic material in water in a quantity and for a time sufficient to couple the anionic material with the diazo and dissolve the coupled product from the unexposed areas; and(d) rinsing with water to provide a printing plate having a reinforced, oleophilic image and a clean, hydrophilic background.
