摘要： The present invention provides a smoothing roller for a printing unit of a rotary printing machine. The smoothing roller is applied to the form cylinder downstream of the ink applicator roller in relation to the direction of rotation of the form cylinder or onto the ink applicator roller itself. The smoothing roller smooths the ink film on the form cylinder or on the ink applicator roller. The outer surface of the smoothing roller has an ink-repelling characteristic. The ink-repelling characteristic is effected by a liquid ink-repelling material such as a separating agent or a dampening medium that is applied to the outer surface of the smoothing roller or by an outer surface of the smoothing roller comprising an ink-repelling material. The two measures for effecting the ink-repellant characteristic of the smoothing roller may also be provided in combination with one another.

摘要： An apparatus and method which reduces solid mottling in an offset printing press. One or more form rolls having a hard elastomeric outer surface, in the range of approximately 50-100 Shore A durometer hardness, preferably approximately 60-90 Shore A durometer hardness, are used to transfer ink to the plate cylinder. The use of a form roll of this type ensures a smoother application of ink to the plate cylinder, which in turn ensures smoother ink application to the blanket cylinder and printed web. If more than one form roll is used, it is preferable that, at a minimum, the final form roll, i.e., the last form roll the plate cylinder contacts in the direction of rotation, be a hard elastomeric form roll. In another aspect of the present invention, the form rolls can be made of a convex shape along their axial length, such that the diameter of the form rolls at their axial center is larger than the diameter of the form rolls at their axial ends. This is done to ensure proper contact between the form rolls and the plate cylinder. The present invention also encompasses a method of printing which reduces solid mottling and consumes less ink than in the prior art for an equivalent optical density.
摘要翻译：减少胶版印刷机中固体斑点的装置和方法。使用具有硬弹性体外表面的一个或多个成形辊，在约50-100肖氏A硬度计硬度的范围内，优选约60-90肖氏A硬度计硬度，以将油墨转移到印版滚筒。使用这种类型的成型辊确保油墨更平滑地应用于印版滚筒，这反过来确保更平滑的油墨应用于橡皮布滚筒和印刷的卷筒纸。如果使用多于一个的成形辊，最好最终的成型辊，即最终的成形辊，印版滚筒在旋转方向上接触，就是硬弹性体形成辊。在本发明的另一方面，成形辊可以沿其轴向长度形成为凸形，使得成形辊的轴向中心的直径大于成形辊在其轴向端部的直径。这样做是为了确保成型辊和印版滚筒之间的正确接触。本发明还包括一种印刷方法，其减少固体斑点并且消耗比现有技术中的等效光密度低的墨水。

摘要： A cylinder (2) for a printing machine, particularly a developing cylinder in an electrographic printing machine, having a rigid, elongated shaft body (10) and a rigid hollow body (11) whose exterior forms the covering and the top and bottom surfaces of the cylinder. In order that, during operation under constant conditions, the cylinder can roll properly against another rigid cylinder of the printing machine, flat sides (12,13) of the hollow body (11) which form the top and bottom surfaces of the cylinder, have centrical bore holes that are larger than the diameter of the shaft body (10) in the area of the flat sides. Located in the space between the shaft body and the flat sides of the hollow body is an elastic material (14,15) which joins the flat sides of the hollow body to the shaft body. Inside the hollow body, in the center between the flat sides of the hollow body one or a plurality of braces (16) are arranged which extend transversely to the figure axis of the shaft body, and which firmly join the hollow cylindrical covering of the hollow body to the shaft body, so that the figure axis of the hollow body and the figure axis of the shaft body coincide in a normal state, and intersect at a small angle under the influence of outer forces.

摘要： A printing machine roller, especially an ink roller, and preferably an ink distributor roller, with a coating of the entire outer cylindrical surface. The coating consists of a support matrix of a good heat-conducting and low-wear metal, e.g., nickel or aluminum-silicon alloy and graphite or plastic particles, e.g., of polyester, inlaid into the metal matrix. The coating is produced by thermal spraying, preferably plasma spraying or flame spraying. The residual porosity of the coating can be varied within wide limits based on process requirements. This residual porosity also permits the ink-friendliness to be varied within wide limits via sealing with an ink-friendly plastic. The roughness of such layers can be adjusted virtually as desired to the individual requirements of the offset process.

摘要： In-line printing and coating method achieves high coat weights (e.g, over 0.7 lb./1,000 sq.ft.) characteristic of blister seal operations and/or high gloss and high scuff resistance requirements, substantially without deleterious slinging. A high volume of coating is applied to a substrate by a coating cylinder supporting a resilient coating transfer surface consisting of an array of laser engraved coating-carrying indentations having substantially equal volumes that are uniformly distributed. An impression surface is positioned adjacent to the coating cylinder, positioned to impress a substrate between the coating transfer surface and the impression surface. A supply roll has a surface for applying liquid coating to the resilient transfer surface. The supply roll surface and the resilient transfer surface are in pressure contact, and adjacent surfaces of the supply roll and the coating cylinder rotate in the same direction. A metering member contacts the supply roll, so the load on the supply roll is metered before it is imparted to the resilient transfer surface. Resilient polymer and rubber surfaces carrying high volumes of coating are also disclosed. The cylinder supporting the resilient transfer surface can be advantageously used in other applications, for instance a roll of a keyless inker of an offset printing unit in a printing press.

摘要： A printing unit of a rotary printing press utilizes a "waterless" planographic printing plate which is fastened on a printing cylinder. This "waterless" planographic printing plate receives ink from a short inking unit and directly prints a material to be printed. An additional printing cylinder, that is also equipped with a "waterless" planographic printing plate, acts as the counterpressure cylinder.

摘要： The present invention has as an object to provide an inking device which prevents the generation of vibration in rollers and is capable of supplying the amount of ink uniformly all the time to the surface of printing plate in the direction of its width. The inking device of the invention is constructed such that the distance between the bottom of the ink pan and the surface of the ink fountain roller, the distance between the surface of the ink fountain roller and the surface of the ink transfer roller and the surface of the roller next to it in the downstream direction are made smaller as the distance proceeds downstream. The ink is transferred from the upstream side to the downstream side, and during this ink transfer, the ink distribution is regulated uniformly in the direction of roller width by means of a doctor blade, etc. Further, the circumferential surface speeds of the rollers are variable, and the vibration of the inking device is prevented by matching the circumferential surface speed of the ink transfer roller to the circumferential surface speeds of the rotating rollers on the downstream side.
摘要翻译：本发明的目的是提供一种防止在辊子中产生振动并且能够将印刷油墨的数量均匀地沿其宽度方向供给到印版的表面的着墨装置。本发明的着墨装置的结构使得墨盘的底部和墨斗辊的表面之间的距离，墨斗辊的表面与墨水转印辊的表面之间的距离以及墨水辊的表面之间的距离随着距离下游的距离，在其下游方向上靠近它的辊更小。油墨从上游侧传送到下游侧，在该墨水转印期间，通过刮刀等使墨水分布均匀地沿辊宽度的方向调节。此外，辊的周向速度为通过使墨水转印辊的周面速度与下游侧的旋转辊的周面速度相匹配来防止上墨装置的振动。
