The invention relates to a sealing system, the sealing system comprising two first sealing members (62) which are each disposed at opposite lateral ends (56) of a doctor blade chamber (48), and two second sealing members (64) which are each disposed at opposite lateral ends (60) of the rotatable roller (46), wherein in operational mode, each of the two first sealing members (62) is in rotating contact with each of the two second sealing members (64) such that a leakage of ink at the opposite lateral ends (56) of the doctor blade chamber (48) is prevented.

It is especially described a control process for intaglio printing, in particular for printing paper securities, such as banknotes. This control process includes defining on an intaglio printing plate (80) control areas (150, 151-155; 170, 171-179) designed in such a manner as to allow in particular evaluation of effects of the printing pressure applied during printing of a substrate by means of the intaglio printing plate (80) and evaluation of effects of the ink coverage applied during inking of the intaglio printing plate (80), which control areas (150, 151-155; 170, 171-179) are engraved in a portion of the intaglio printing plate (80) in order to produce corresponding printed control zones (160, 161-165) on the substrate. The process further includes carrying out of measurements in the printed control zones allowing evaluation of the printing pressure applied during printing of the substrate as well as of the ink coverage applied during inking of the intaglio printing plate (80).

A doctor blade (5, 7) for contact with an anilox roller (15) comprises a flat, elongate base element having a thickness of less than about 0.3 mm, which, along a longitudinal region of the doctor blade adapted for contact with said anilox roller, is provided with a coating (43). The coating comprises a metal matrix and at least about 65% by weight of one or more ceramic(s). The coating comprises 0 to 65% by weight of chromium carbide. An inking arrangement comprises an anilox roller and a doctor blade. A doctor blade is used in flexographic printing.

Intaglio printing press systems for recto-verso intaglio printing of sheets, in particular for the production of banknotes and the like securities, wherein first and second intaglio printing presses are operatively-coupled to one another by a sheet processing and transporting system comprising an automated guided vehicle system for automatically transporting sheets from a sheet delivery station of the first intaglio printing press where recto printing is performed to a sheet feeding station of the second intaglio printing press where verso printing is performed.

A panel of the present invention includes a substrate, an electrode provided on the substrate, and a transparent conductive layer provided on the substrate along a side of the electrode. The electrode includes a contact region in contact with the transparent conductive layer and a non-contact region out of contact with the transparent conductive layer. Preferably, a part of the electrode is exposed through the transparent conductive layer. Preferably, the conductive layer is separated into one side and the other side of the electrode extending a predetermined direction.

Improved pliable print rollers for high speed drink can printing machines increase the pliable roller life five- to ten-fold at comparable ink thickness and machine speed. The improved performance results from the selection of materials utilized including a combination of elastomers, and in some case an essentially oil-free composition, and an associated manufacturing process not previously utilized to create pliable print rollers for high speed drink can printing machines. In particular a particular embodiment, the composition includes a combination of elastomers (e.g., 75% polyisoprene and 25% polybutadiene), a filler (e.g., silica), a curing agent (e.g., peroxided), and other additives (e.g., pigment, antioxidant, antiozonant) with little or no oil added as a softener. An illustrative composition including 150 parts by weight contains 100 parts elastomer, 35 parts filler, 4 parts curing agent, and 11 parts other additives (i.e., zero parts oil softener).

Disclosed is a thin-film radio frequency absorber material that is mass-produced by a high-speed manufacturing method of printing a highly controlled pattern of conductive ink squares onto a thin roll film, resulting in a lightweight low-cost radio frequency absorber component that is flexible for use in multiple novel configurations. The roll film material and printed squares are each easily adjustable to a specific size and thickness within the manufacturing process to coincide with control and protections related to variable specific radio and radar wave frequencies. Further integration into the three-layered thin-profile radio frequency energy absorber and reflector assembly provides control and protection properties related to radio and radar frequency, infrared, electromagnetic pulse, electromagnetic interference, and thermal insulation values in structural building panels utilized in lightweight structures such as the foldable transportable structure or other types of building and protection assemblies.

A method for producing color steel plate with multicolored patterns, the PLC control module of servo control system collects the process and rotation speed of each roller of the roller coating unit, calculates out and makes the theoretical roller surface linear velocity be consistent with the process rotation speed; conversely, the actual roller surface linear velocity of each roller of roller coating unit is collected by servo control module having an encoder, and the signal of actual roller surface linear velocity is input into the PLC control system, so that PLC control system can compare actual and theoretical roller surface linear velocity, and adjust current frequency until actual and theoretical roller surface linear velocity are consistent. Control method ensures actual roller surface linear velocity is consistent with process rotation speed, so there is no need to stop the line for adjusting in the production process, thus increasing the production efficiency.
