Abstract:
The invention relates to a mask (M) for digital operation and printing, comprising a porous structural mesh (1) for supporting material, a cover layer (2), and a mask material (3) arranged between the structural layer (1) and the cover layer (2), wherein the mask material (M) can be relatively positioned on the mesh (1) so as to form a mask that can be reconfigured for printing. The invention also relates to a method using said mask.
Abstract:
The invention relates to methods and apparatuses for producing Braille embossing profiles and for producing Braille script embossments. Furthermore, the invention also relates to Braille embossing profiles per se. There is provision, in particular, in conjunction with flatbed punching firstly and offset printing secondly, for simple possible solutions to be made available for producing Braille script embossments. To this end, the Braille male die and the Braille female die can be configured for flatbed punching such that they can be connected magnetically to one another for transfer and exact positioning in the punching die. For offset printing, advantageous exact positioning of the Braille male die is proposed by means of a printed sheet template which can subsequently be pressed into a female die blank. The Braille male die is manufactured in each case preferably from a male die blank which has all the Braille embossing points.
Abstract:
Methods of forming a flexographic printing plate are described and include disposing a polymeric substrate onto a master tool having a plurality of recesses defining a master tool pattern. A solvent is disposed within the recesses. Then, the solvent is diffused into the polymeric substrate to form a substrate relief pattern that is complementary to the master pattern. The substrate relief pattern is then cured to form a flexographic printing plate. Flexographic printing plates are also described.
Abstract:
Die Erfindung betrifft Verfahren und Vorrichtungen zur Herstellung von Braille-Prägeprofilen sowie zur Herstellung von Brailleschrift-Prägungen. Ferner betrifft die Erfindung auch Braille-Prägeprofile als solche. Insbesondere ist vorgesehen, in Verbindung mit einem Flachbettstanzen einerseits und einem Offsetdrucken andererseits einfache Lösungsmöglichkeiten für das Erstellen von Brailleschrift-Prägungen zur Verfügung zu stellen. Dazu kann für das Flachbettstanzen die Braille-Patrize mit der Braille-Matrize für eine Übertragung und exakte Positionierung im Stanzwerkzeug magnetisch miteinander verbindbar ausgebildet sein. Für das Offsetdrucken ist eine vorteilhafte exakte Positionierung der Braille-Patrize mittels einer Druckbogen-Schablone vorgeschlagen, die sich anschließend in einen Matrizenrohling eindrücken kann. Die Braille-Patrize wird jeweils bevorzugt aus einem sämtliche Braille-Prägepunkte aufweisenden Patrizenrohling gefertigt.
Abstract:
The method for structuring the surface of a steel embossing roller by means of short pulse laser, where the structuring is a macrostructuring with dimensions of over 20 μm and depths up to 150 μm and more, distinguishes itself by the following parameter combination: a) in single pulse operation a fluence in the range of 0.5 J/cm 2 to 3.5 J/cm2 and in burst operation a mean burst fluence of 0.5 J/cm 2 to 70 J/cm 2 per pulse, b) wavelength of 532 nm to 1064 nm, c) repetition rate of 1 kHz to 10 MHz, d) pulse to pulse spacing on the workpiece of 10 % to 50 % of the beam diameter for the femtosecond laser and of 10 - 25 % and 40 - 50 % of the beam width for the picosecond laser, e) laser pulse position near the workpiece surface, and f) deflection velocities of up to 100 m/s and more. *** Such a method allow manufacturing a complete embossing roller with teeth and gaps for producing logos, the teeth having variable heights, shapes, and spacings, for embossing e.g. innerliners for cigarette packaging.

Abstract:
It is described a method for producing a laminar male die(l) of the interchangeable type, for printing Braille characters (4) on yielding supports. The method comprises the step of punching the metal foil (2) that forms the body of the male die to obtain a plurality of first points in relief (3) on a first face of the foil. The first points define one or more characters in Braille alphabet. The method comprises the further step of punching the metal foil to obtain at least two second points ( 5,6, 7,8) in relief on the other side of the foil; the second points in relief are aligned with corresponding receiving seats of an outer male die-holding support. A male die obtained with the previous method and the respective manufacturing apparatus are also described.
Abstract:
Beim Einrichten einer Prägeform in einer rotativen Stanzmaschine oder in einer Rotationsdruckmaschine sollen die Rüstzeiten deutlich herabsetzt werden. Hierzu wird entweder die Matrize (A2) oder die Patrize (A3) einer Prägeform durch eine Formmasse gebildet, die von der entsprechenden Gegenform in der Maschine geprägt wird und anschließend verformt aushärtet. Bei der Matrize (A2) wird eine Überfüllung (A5) durch ein gleichmäßiges Verfahren des Registers in allen Richtungen um einen definierten Verfahrweg erzeugt.
