摘要： An intermediate roller positioned between a fountain solution vapor supply and an imaging member decouples fountain solution vapor deposition from the surface of the imaging member. The intermediate roller may be temperature controlled. A uniform layer of fountain solution condenses onto the surface of the temperature controlled intermediate roller regardless of the imaging blanket temperature. The fountain solution condensate layer deposited onto the intermediate roller splits and deposits a thin uniform layer of fountain solution liquid onto the imaging member surface. This liquid layer split may be independent of the temperature of the imaging member surface, resulting in a uniform layer of fountain solution on the imaging blanket for better imaging quality. Remotely locating the vaporizing chamber away from the imaging member prevents undesired heat transfer from a hot vaporizing chamber/baffle to the imaging member surface.

摘要： There is disclosed a selective wetting apparatus (2) comprising a roller (20) rotatable about a roller axis (24) and comprising a wettable roller surface (22); an applicator unit (10) having a lip (12) which extends parallel to the roller axis (24) and is radially spaced apart from the roller surface (22) by a gap (30), wherein the applicator unit (10) is to convey liquid agent (14) towards the roller (20) so that the liquid agent (14) forms a liquid bridge (32) over the gap (30) to wet a wettable axial portion of the roller surface (22); and a flow guide (50) to direct a gas flow (56) into a regulated axial portion of the gap (30) to locally prevent formation of a liquid bridge (32), and thereby prevent wetting of a corresponding axial portion of the roller surface (22).

摘要： There is described an inking apparatus of a printing press, in particular an offset or letterpress printing press, comprising at least one ink duct (11, 12) with an ink supply roller (13, 14), an ink roller train (30) comprising at least one inking roller (31) which receives ink from the at least one ink duct (11, 12), and at least one vibrator roller (15, 16) interposed between the ink supply roller (13, 4) and the inking roller (31), which vibrator roller (15, 16) is swung back and forth between the ink supply roller (13, 14) and the inking roller (31) and intermittently transfers ink from the ink supply roller (13, 14) to the inking roller (31). A circumference of the vibrator roller (15, 16) exhibits an ink-transfer 10 structure (15a, 16a) which reflects a desired inking profile of a printing plate to be inked by the inking apparatus and is designed to modulate a quantity of ink transferred by the vibrator roller (15, 16). The ink-transfer structure (15a, 16a) on the circumference of the vibrator roller (15, 16) is subdivided, in a circumferential direction (y) of the vibrator roller (15, 16), into an integer number 1 (r) of individual ink-transfer portions (15b, 16b) that are repeated with a determined circumferential period (Δy) in the circumferential direction (y), each individual ink-transfer portion (15b, 16b) reflecting the desired inking profile of the printing plate to be inked by the inking apparatus. A contact length (CL) over which the vibrator roller (15, 16) runs in contact with the ink supply roller (13, 204) is equivalent to the determined circumferential period (Δy) of the individual ink-transfer portions (15b, 16b) or to an integer multiple of the determined circumferential period (Δy) of the individual ink-transfer portions (15b, 16b).

摘要： A liquid supply assembly for use with a printing system of a type in which a liquid is deposited from the liquid supply assembly in a receiving region on a plate and any excess of the liquid in the receiving region is scraped from the plate by the liquid supply assembly. To this end, the liquid supply assembly employs a reusable cup, a disposable cup insert and a scraping element. As assembled, the reusable cup includes a reusable liquid reservoir, the disposable cup insert includes a temporary liquid reservoir holding the liquid within the reusable liquid reservoir, and the scraping element includes a conduit facilitating a flow of the liquid held by the temporary liquid reservoir through the conduit to the plate.

摘要： Inking unit rolls include at least one ink applicator roll, which rotates in an ink fountain filled with printing ink and picks up printing ink from the latter, and a plate cylinder, which serves as a printing plate carrier and onto which ink can be transferred, directly or indirectly, by the ink applicator roll. The short inking unit is therefore equipped with a small number of inking unit rolls and, at the same time, nevertheless ensures a uniform, homogeneous application of ink to the plate cylinder, that is to say the ink splitting on ink-carrying rolls of a short inking unit for a rotary printing machine is improved. At least one of the inking unit rolls is provided, at least on its surface, with a coating having powerful microdipoles, in particular made of ferroelectric material. This circumferential surface is assigned electric means in order to produce an electric field by means of a DC/AC voltage, in order to polarize and depolarize the microdipoles of the circumferential surface in the form of a homogeneous or periodic charge image, so that an ink layer resting on it is given a desired electric roughness.
摘要翻译：单元辊包括至少一个涂墨辊，其在填充有印刷油墨的墨斗中旋转并从其中拾取印刷油墨;以及印版滚筒，其用作印版载体并且可以将油墨转印到其上，直接或间接地通过油墨涂布辊。因此，短的上墨单元配备有少量的着墨单元辊，并且同时确保了油墨均匀地均匀地施加到印版滚筒上，也就是说在油墨承载辊上的油墨分离用于旋转印刷机的短的上墨单元得到改进。至少一个上墨单元辊至少在其表面上设置有具有强大的微电极的涂层，特别是由铁电材料制成。该圆周表面被分配电气装置以便通过DC / AC电压产生电场，以便使均匀或周期性电荷图像形式的圆周表面的微二极体极化和去极化，使得墨水放置在其上的层具有期望的电粗糙度。

摘要： The intaglio printing machine comprises a plate cylinder (4) with a plurality of engraved printing plates equipped with intaglio cuts representing the elements of a main design and with less deep and finer intaglio cuts representing the elements of a safety background, an impression cylinder (3), a wiping device (10) and a multicolor inking system. This inking system consists of a collector inking cylinder (5) having an elastic surface interacting with the engraved plates mounted on the plate cylinder (4) and having the same diameter as this. The collector inking cylinder (5) is inked by as many selective color inking cylinders (7) as there are colors to be printed, these selective color inking cylinders (7) having reliefs corresponding to the colored zones of the safety background and of the main design, an inking device (8) being associated with each selective color inking cylinder (7). If appropriate, the diameter of the collector inking cylinder can also be double or triple the diameter of the plate cylinder.

摘要： The printing machine is composed of an indirectly printing printing unit (A), and a sheet transport device (B), composed solely of drums (18, 19, 20, 22, 23, 24), and of a following intaglio printing unit (C). The indirectly printing printing unit (A) has two interacting blanket cylinders (3, 5), each of which is inked with several colors by several plate cylinders (12, 15; 7, 10). The sheets are passed onto one of the blanket cylinders (3) from a carry-over drum (2) and, after passing through the nip between two blanket cylinders (3, 5), thereby being printed on both sides, are taken over by a transfer drum (18) of the sheet transport device. The circumferential region which is located between the carry-over drum (2) and transfer drum (8) and over which the sheet passes extends over at most 180.degree., preferably less than 150.degree., so that that free circumferential region of this blanket cylinder not covered by the sheet is available for accommodating several plate cylinders.
