Description
Metallfolie zur Herstellung von Druckformen. Die Verwendung von mit Maschinen oder von Hand beschriebenen Metallfolien als Druckform ist bekannt (s. britische Patentschriften 531/r886 und 16173/r893). Praktisch bewährt hat sich dieses Verfahren bei der Herstellung von Druckplatten für Adressiermaschinen, jedoch kann man hierbei schon nicht mehr von Folien sprechen. Es wind vielmehr idünnes Zinkblech verwendet, welches mittels hierfür gebauter, mit positiven .und negativen .Stahltypen versehener Prägemaschinen von großer Durchschlagkraft beschriftet wird. Es dürfte jedoch kaum möglich sein, in eine ,beim Druck genügend Widerstand bietende Folie mit einer ,Schreibmaschine (die Typen so tief einzuschlagen, idaß der Grund der Platte nicht mitdruckt.Metal foil for the production of printing forms. Using with Machines or hand-written metal foils as a printing form are known (see Sect. British patents 531 / r886 and 16173 / r893). This has proven itself in practice Process in the manufacture of printing plates for addressing machines, however one no longer speaks of foils. Rather, it is thin sheet zinc used, which by means of specially built, with positive .and negative .steel types provided stamping machines with great impact. It should however, it would hardly be possible to use a film that offers sufficient resistance to pressure with a typewriter (to hit the guys so deep that the reason for the Plate does not print.
Die Erfindung ermöglicht es nun, brauchbare Druckplatten durch Beschriftung von Metallfolien mit gewöhnlichen Schreibmaschinen herzustellen, und zwar wird dies @da(durch erreicht, :daß die Folie vor :dem Beschreiben mit einer Rasterprägung versehen wird. Ein Abdruck von einer gewöhnlichen glatten Folie ergibt eine ganze schwarze Fläche. .Ein Abzug von einer gerasterten Folie ergibt eine leicht graue Fläche, die um so heller wird, j e feiner und spitzer idie Punkte eingeprägt sind. Da auch .bei :der beschrifteten Rastertonfolie die ganze Fläche mitdruckt, ist eine besondere Erhabenheit der eingeschriebenen Zeichen nicht erforderlich; es genügt vielmehr, daß durch Idas Einschreiben, welches auf der Rückseite geschieht, die Punkte auf der Vorderseite vernichtet werden.The invention now makes it possible to print usable printing plates of metal foils with ordinary typewriters, namely this will @da (achieved by: that the foil before: writing with a grid embossing is provided. An imprint from an ordinary smooth film makes a whole black area. A print from a screened film produces a slightly gray one Area which becomes lighter the finer and more pointed the points are embossed. There is also a special sublimity of the inscribed characters not required; it is sufficient rather, that by Ida's registered letter, which happens on the reverse, the Points on the front are destroyed.
Nun ist zwar bereits im »Deutschen Buch-und Steindrucker«. 1921, Heft 7, S. 443 ein ähnliches Verfahren veröffentlicht, welches den-gleichen Endzweck verfolgt (s. auch ,die amerikanischen Patentscihriften 891499 und 1112356). Es handelt sich jedoch hierbei um die Herstellung von Matrizen, welche erst das Negativ für eine durch Idas Stereotypieverfahren hergestellte Druckplatte ergeben.Now it is already in the "German book and stone printer". 1921, issue 7, p. 443 a similar method is published which has the same end-purpose pursued (see also the American patent documents 891499 and 1112356). It deals However, this involves the production of matrices, which are only the negative for result in a printing plate made by Ida's stereotype process.
Die Vorteile der Erfindung bestehen darin, :daß 1. das Verfahren, ida :direkt von der beschriebenen Platte gedruckt wird, bedeutend einfacher ist, 2. jede Folie sofort für den Flachdruck, wie auch für Rotationsdruck verwendet werden kann, 3. Druckplatten von beliebiger Länge hergestellt werden können, was für Spezialzwecke, z. B. für den Druck von Adressen, von größter Bedeutung ist.The advantages of the invention are that: 1. the method, ida: is printed directly from the plate written on is significantly easier, 2. Each foil can be used immediately for flat printing as well as for rotary printing can, 3. printing plates of any length can be made, which is for special purposes, z. B. for printing addresses, is of the utmost importance.
