Description
Die Erfindung betrifft ein Verfahren zum Herstellen von Mehrfarbendruck mittels einer einzigen Druckform. Es ist bekannt, bei Mehrfarbendruck so viel Auftragwalzen zu verwenden, wie das Bild Farben enthält, und a.us deren Überzug so viel herauszuschneiden, daß auf jeder Auftragwalze nur derjenige Teil des Überzuges stehenbleibt, der ihrer Farbe entspricht. Diese bekannten Anordnungen lassen in bezug auf die Wiedergabe aller Feinheiten des Originals zu wünschen übrig. Um nun den herauszuschneidenden Teil des Überzuges jeder Auftragwalze schnell zu ermitteln, wird gemäß der Erfindung inThe invention relates to a method for producing multicolor printing by means of a single printing form. It is known to have so many applicator rollers in multi-color printing use how the picture contains colors, and cut out so much from their coating, that on each applicator roller only that part of the coating remains that of theirs Color matches. These known arrangements leave with respect to the reproduction all the subtleties of the original leave much to be desired. Now to the one to be cut out To quickly determine part of the coating of each applicator roll is according to the invention in
1S die Maschine zuerst die Druckform eingelegt, die in Hoch- oder Tiefdruck den ganzen Abdruck ergibt, dann die Auftragwalzen in die Lage eingebracht, die sie beim Auftragen der Farbe auf die Druckform einnehmen müssen, 1 S the machine first inserts the printing form that produces the entire imprint in relief or gravure printing, then the application rollers are brought into the position that they have to assume when applying the ink to the printing form,
ao wobei ihre Stellung gegenüber der allgemeinen Antriebsvorrichtung genau eingestellt wird, und schließlich die Druckform nacheinander mit den verschiedenen Farben eingefärbt und die Maschine so lange laufen gelassen, bis jede der Auftragwalzen das einfarbige Abbild des Originals' aufgenommen hat, welches Abbild dann als Vorbild für das Wegschneiden des Überzuges dient. ao whereby their position in relation to the general drive device is precisely adjusted, and finally the printing form is successively inked with the different colors and the machine is left running until each of the applicator rollers has picked up the monochrome image of the original, which image then serves as a model for the Cutting away the coating is used.
Die Erfindung ist auf der Zeichnung inThe invention is shown in the drawing in
vier Abbildungen veranschaulicht, und zwar stellen dar:four figures illustrated, namely represent:

Es werde angenommen, daß das wiederzugebende Bild gemäß Abb. 2 einen Untergrund t besitzt und in drei Teile p1, p2, ps von verschiedenen Farben unterteilt ist.·It is assumed that the image to be reproduced according to Fig. 2 has a background t and is divided into three parts p 1 , p 2 , p s of different colors.
Betrachtet man nun einen Querschnitt x-x des Bildes parallel zur Walzenachse, so erkennt man, daß die farbige Wiedergabe dieser Linie χ aus fünf Elementen besteht, nämlichIf one now looks at a cross-section xx of the image parallel to the roller axis, one recognizes that the colored reproduction of this line χ consists of five elements, namely
a-b = Farbe p1, ab = color p 1 ,
b-c = Untergrund t, bc = background t,
c-d = Farbe p2, cd = color p 2 ,
d-e z= Farbe ps, de z = color p s ,
e-f = Untergrund f. ef = subsurface f.
Erfindungsgemäß wird zur Vorbereitung der Auftragwalzen in eine Maschine die Druckform F (Abb. 1) oder das Klischee oder die gravierten Zylinder eingelegt, die den nötigen Hoch- oder Tiefdruck ergibt; dann werden die Walzen R1, R2, R3 eingelegt, die mit einem leicht elastischen BelagÄ versehen sind, wobei man dafür Sorge trägt, die einzelnen Walzen genau gegenüber den Mitnehmevorrichtungen der Maschine einzustellen. Darauf färbt man die Druckform F zuerst mit einer Farbe ein und läßt die Maschine laufen, bis die Walze R1 den genauenAccording to the invention, the printing forme F (Fig. 1) or the cliché or the engraved cylinder is inserted into a machine to prepare the applicator rollers, which results in the necessary letterpress or gravure printing; then the rollers R 1 , R 2 , R 3 are inserted, which are provided with a slightly elastic coveringÄ, whereby care must be taken to set the individual rollers exactly in relation to the driving devices of the machine. Then the printing forme F is first colored with a color and the machine is allowed to run until the roller R 1 is the exact one
Abdruck des Originals aufgenommen hat, wobei die Form F sich mit dem sie tragenden Wagen C unter der Walze R1 fortbewegt. Ebenso verfährt man mit den anderen Auftragwalzen R2, R3, nachdem man die betreffenden Teile der Druckform entsprechend eingefärbt hat. Darauf nimmt man die Auftragwalzen R1 bis R3 heraus und schneidet den Belag derart heraus, daß auf der Walze R1 Imprint of the original has taken, the form F moves with the carriage C carrying it under the roller R 1 . The same procedure is followed with the other applicator rollers R 2 , R 3 after the relevant parts of the printing form have been colored accordingly. Then you take out the application rollers R 1 to R 3 and cut out the covering in such a way that on the roller R 1
ίο nur das der Farbe/»1 entsprechende Relief, auf der Walze R2 nur das der Farbe p2 entsprechende Relief und auf der Walze R3 nur das der Farbe ps entsprechende Relief stehenbleibt. ίο only the relief corresponding to the color / » 1 , on the roller R 2 only the relief corresponding to the color p 2 and on the roller R 3 only the relief corresponding to the color p s remains.
Sodann werden die Auftragwalzen wieder genau in die Maschine eingelegt und mit einer Einfärbevorrichtung, versehen, die aus dem Farbkasten Q, der Farbkastenwalze P und der Abstreifschiene 5" besteht.The applicator rollers are then placed exactly back into the machine and provided with an inking device, which consists of the ink fountain Q, the ink fountain roller P and the stripping bar 5 ″.
Nunmehr wird' in bekannter Weise die Druckform durch die Auftragwalzen mit den verschiedenen Farben eingefärbt und von ihr nach jedem. Einfärben ein Abdruck genommen. Wenn es sich um Tiefdruck handelt (Radierungen, Heliogravüren, Kupferstiche), dann wird naturgemäß nach dem Einfärben die Oberfläche der Druckplatte durch eine geeignete Wischvorrichtung von ihrem Farbüberschuß befreit.Now is' in a known manner, the printing form by the application rollers with the colored different colors and by it according to each. Coloring an impression taken. If it is gravure printing (etchings, heliogravures, copper engravings), then naturally, after inking, the surface of the printing plate is replaced by a suitable one Wiping device freed from their excess paint.
