摘要:
The invention relates to an image printed on a substrate, the image comprising: a plurality of magnetic flakes wherein a portion of the plurality of magnetic flakes are aligned in an arching pattern relative to a surface of the substrate so as to create a contrasting bar across the image appearing between a first adjacent field and a second adjacent field, the contrasting bar appearing to move relative to the first adjacent field and the second adjacent field as the image is tilted.

The invention relates to a method of aligning magnetic flakes, which includes: coating a substrate with a carrier having the flakes dispersed therein, moving the substrate in a magnetic field so as to align the flakes along force lines of the magnetic field in the absence of an effect from a solidifying means, and at least partially solidifying the carrier using a solidifying means while further moving the substrate in the magnetic field so as to secure the magnetic flakes in the carrier while the magnetic field maintains alignment of the magnetic flakes.

There is described a cylinder body (10) for orienting magnetic flakes contained in an ink or varnish vehicle applied on a sheet-like or web-like substrate, which cylinder body (10) has a plurality of magnetic-field-generating devices (50, 60) disposed on an outer circumference of the cylinder body (10). The cylinder body (10) comprises a plurality of distinct annular supporting rings (40) distributed axially along a common shaft member (20), each annular supporting ring (40) carrying a set of magnetic-field-generating devices (50, 60) which are distributed circumferentially on an outer circumference of the annular supporting rings (40).

Die Erfindung betrifft ein Qualitätskontrollsystem zur Überwachung von Druckbogen. Mit dem System sollen als fehlerhaft erkannte Drucke gekennzeichnet werden. Zur Kennzeichnung von fehlerhaften Druckbogen ist vorgesehen, mittels einer Lasereinrichtung kennzeichnende Merkmale, spezielle Teile oder Flächen des Druckbogens so zu verändern, dass eine einfache Erkennung fehlerhafter Bogen möglich wird.
摘要:
A contact cleaning machine for removing particulates and other undesirable debris from the surfaces of articles moving along a curved path under the cleaning machine, without disturbing the orientation of the articles which cannot be clamped against movement. Cleaning is performed by a roller (22) which is mounted in the machine to roll across the tops of the articles as they pass underneath. The peripheral surface (28) of the roller is coated with a tacky adhesive to lift off the undesirable particulates. To avoid the roller applying differential forces to the article, the roller is made conical and convergent towards the axis of curvature of the path followed by the article. The avoidance of differential forces on the unclamped articles eliminates any tendency for the cleaning roller to turn the articles. To prevent build-up of dirt on the cleaning roller, it is backed up by a further roller with a peripheral surface that has a greater level of adhesive tackiness, such that particulates transfer from the cleaning roller to the backup roller. The contact cleaning machine is applicable to cleaning the surfaces of compact discs having labels printed on them in a multi-stage indexing turret printing machine.

Es ist bekannt, gedruckte Farben durch Gefrieren so zu fixieren, daß sie in der Textilie oder dgl. an Ort und Stelle bleiben, nicht Auslaufen und kurz nach dem ersten Druck der zweite Druck stattfinden kann. Es besteht jedoch Gefahr, daß die Farben an der Unterseite der Kühlplatte der Gefriertrockenstation hängenbleiben und damit verschleppt werden, wodurch Ausschuß erzeugt wird. Die Erfindung beseitigt diesen Nachteil, indem sie eine genügend dicke Rauhreifschicht anwachsen läßt und mit den unteren Volumina der Rauhreifschicht kühlt statt mit der Kühlplatte oder dgl.

A continuous web printing apparatus and method employs a printing station (14) for printing electron beam curable inks on a continuous web, a coating station (16) for coating the printed web with an electron beam curable coating, and an electron beam curing unit (18) for rapidly curing the inks and coating.
摘要:
A system and a method for irradiating an object and potentially for controlling the irradiation or other conditions relating to an effect of the irradiation. A sensor is translated along a longitudinal direction of the radiation emitter and in a space between the radiation emitter and the objects irradiated to arrive at information relating to a parameter relating to the effect of the irradiation, such as the radiation, and derived in the space between the radiation emitter and the objects irradiated. Calibrating the sensor readings and adjusting the radiating emitter output, thereby controlling the irradiation.
