- the object of the invention is to find a method by means of which, instead of the color swatch, the areas to be kept free of the paint application can be located on a rubber blanket.
- the advantage of the invention is that set-up times are reduced because the areas that are not to be painted can be rationally located in advance on the rubber blanket (lacquered blanket), which previously was not possible. This is the first time that a reference copying process has been found on offset rubber blankets.
- printing plates can be clamped on forme cylinders with painting options in conjunction with a dual-purpose tensioning rail for optional tensioning of a rubber blanket or a printing plate with one or more self-adhesive rubber blankets, and thus a recessed inline coating can be carried out.

- the adhesive must not be soluble in water.
- the rubber blanket surface must be made grease-free with solvent cleaners even before opening, and paint residues and the like must be removed. If the rubber blanket surface of the drawn-on cloth repels pearly water, an approx. 10% phosphoric acid solution is to be applied before cleaning with chalk, which should take effect for about 2 minutes.

- Exposure example 5,000 watt metal halide lamp, distance 1 m, approx. 90 seconds, depending on the color of the blanket surface.
- the polyvinyl alcohol copying layers are undyed layers, so that the color change due to the exposure is not very great. Even the use of layers that have already been colored before coating does not provide a clearly visible contrast due to the strong inherent color of the substrate.
- the rubber blanket can either be placed on an aluminum printing plate, i.e.
- a metal carrier can be attached using an adhesive or a double-sided adhesive film, or a self-adhesive rubber blanket or several parts that can be purchased can also be glued directly onto a suitable carrier plate.
- Coating and copying onto a rubber blanket tensioned with the same force as is required for tensioning a rubber blanket on a rubber blanket cylinder is also suitable.
- copying templates when coating on a flat, neither stretched nor glued-on blanket, copying templates can be used which extend in the circumferential direction, i.e. Direction of travel of the printing material through the printing machine, reduced by as much as percent in the circumferential direction, as the stretching of the rubber blanket used for varnishing when stretching on the cylinder is between 1 and 3% depending on the type of blanket.
- wipe-on copying layers are also suitable. These copy layers are only wiped onto the cleaned, dry surface with a sponge, they are not spun or poured.
- the wipe-on copy layer works with diazo salts and not with bichromate as a light-sensitive component.
- a coating developer is used to develop the exposed layer.
- Wipe-on copy layers or paint developers are e.g. known as the "Neganol process". With this copying process a reference copy on blanket surfaces is also possible.

Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines Gummituches für Inline-Lackierungen mit Dispersionslack auf wässriger Basis oder in Verbindung mit UV-Lack resistenten Gummitüchern auch zum Auftrag von niedrig viskosem UV-Lack in Rotationsdruckmaschinen nach dem Oberbegriff des ersten Patentanspruchs.The invention relates to a process for the production of a rubber blanket for inline coatings with an aqueous-based dispersion coating or, in conjunction with UV coating-resistant rubber blankets, also for the application of low-viscosity UV coating in rotary printing machines according to the preamble of the first claim.
Beim Inline-Lackieren (Farbe-Lack, naß-in-naß) ist es manchmal erforderlich, Klebelaschen, Stempelfelder und ähnliches frei vom Lackauftrag zu halten. ln diesen Fällen wird die oberste Gummischicht des auf einem Formzylinder aufgespannten Gummituches (Lacktuches) entsprechend der Lage und Größe der auszusparenden Flächen eingeschnitten und abgezogen. Bei genauen Arbeiten wird die Lage der nicht zu lackierenden, d.h. auszuschneidenden Partien des zum Lackieren eingesetzten Gummituches so bestimmt, daß ein Farbabklatsch der die Anhaltslinien liefernden Farbform, übertragen durch den Bedruckstoff, durch Abdruck auf das trockene Gummituch (Lacktuch) aufgebracht wird. Das Ausschneiden der entsprechenden Stellen in der Maschine ist zeitaufwendig und verlängert die Rüstzeit. Auch das Ausspannen des Gummituches, nachdem es den Farbabklatsch erhalten hat, um es zeitlich parallel zum kompletten Einrichten der Farbformen der inline-laufenden Druckmaschine auszuschneiden, ist, weil es erneut eingespannt werden muß, immer noch zeitaufwendig und vor allen Dingen nicht vorab zu erledigen.With inline painting (paint-varnish, wet-on-wet) it is sometimes necessary to keep adhesive tabs, stamp fields and the like free from the application of paint. In these cases, the uppermost rubber layer of the rubber blanket (lacquer blanket) stretched on a forme cylinder is cut and pulled off in accordance with the position and size of the areas to be left blank. For precise work, the position of the non-paintable, i.e. The parts of the rubber blanket used for painting are to be cut out in such a way that a color copy of the color form that provides the reference lines, transferred through the printing material, is applied to the dry rubber blanket (coating blanket) by printing. Cutting out the corresponding places in the machine is time-consuming and extends the set-up time. Unclamping the rubber blanket after it has received the color swipe so that it can be cut out in parallel with the complete setup of the color forms of the inline printing press is still time-consuming because, above all, it cannot be done in advance.
Aufgabe der Erfindung ist es, ein Verfahren zu finden, mit dem anstelle des Farbabklatsches vorab die vom Lackauftrag freizuhaltenden Stellen auf einem Gummituch lokalisierbar sind.The object of the invention is to find a method by means of which, instead of the color swatch, the areas to be kept free of the paint application can be located on a rubber blanket.
Gelöst wird diese Aufgabe nach dem Kennzeichen des ersten Patentanspruchs.This problem is solved according to the characteristic of the first claim.
Weiterbildungen ergeben sich aus den Unteransprüchen und der Beschreibung.Further developments result from the subclaims and the description.
Der Vorteil der Erfindung besteht darin, daß Rüstzeiten gesenkt werden, weil die nicht zu lackierenden Stellen in rationaler Weise vorab auf kopiermäßigem Wege auf dem Gummituch (Lacktuch) lokalisierbar sind, was bisher nicht möglich war. Damit wurde erstmalig ein Anhaltskopierverfahren auf Offset-Gummituch gefunden. Außerdem können an Formzylindern mit Lackiermöglichkeiten in Verbindung mit einer Doppelzweckspannschiene zum wahlweisen Spannen eines Gummituches oder einer Druckplatte mit einem oder mehreren körperselbstklebenden Gummitüchern auch Druckplatten eingespannt und damit eine ausgesparte Inline-Lackierung ausgeführt werden.The advantage of the invention is that set-up times are reduced because the areas that are not to be painted can be rationally located in advance on the rubber blanket (lacquered blanket), which previously was not possible. This is the first time that a reference copying process has been found on offset rubber blankets. In addition, printing plates can be clamped on forme cylinders with painting options in conjunction with a dual-purpose tensioning rail for optional tensioning of a rubber blanket or a printing plate with one or more self-adhesive rubber blankets, and thus a recessed inline coating can be carried out.
Nachstehend wird die Erfindung an einem Ausführungsbeispiel näher erläutert.The invention is explained in more detail below using an exemplary embodiment.
Bei der Herstellung einer Anhaltskopie auf Offset-Gummitüchern wird die folgt vorgegangen. Nach einer besonders auf die Oberflächeneigenschaften eines Offset-Gummituches abgestimmten chemisch-physikalischen Vorbehandlung wird eine speziell dafür ausgesuchte durch Chromierung sensibilisierte Polyvinylalkohol-Kopierschicht aufgeschleudert, aufgegossen oder aufgewischt. Das Verhältnis beträgt ca. 40 cm³ Chromierung auf ca. 1.000 cm³-Schicht. Die chromierte Kopierschicht wird durch ein weiches Papierfilter filtriert, um die beim Einmischen (Schütteln) entstandenen Blasen zu entfernen. Die Oberfläche eines neuen selbstklebenden Gummituches,welches auf eine Alu-Offsetplatte aufgezogen ist, wird mit Schlämmkreide und wenig Wasser mittels Plüschtampon oder einer sehr weichen Bürste in kleinen kreisförmigen Bewegungen intensiv bearbeitet. Anschließend wird mit viel Wasser gespült.The following procedure is used to produce a reference copy on offset rubber blankets. After a chemical-physical pretreatment that is specially tailored to the surface properties of an offset rubber blanket, a specially selected chroming-sensitized polyvinyl alcohol copying layer is spun on, poured on or wiped off. The ratio is approx. 40 cm³ chrome plating on approx. 1,000 cm³ layer. The chromed copying layer is filtered through a soft paper filter in order to remove the bubbles that form when mixed (shaken). The surface of a new self-adhesive rubber blanket, which is mounted on an aluminum offset plate, is worked intensively with slurry chalk and a little water using a plush pad or a very soft brush in small circular movements. Then rinse with plenty of water.
Gummitücher, die bisher zum Drucken bereits eingesetzt wurden und nun zum Lackieren verwendet werden sollen, können mit Kleber oder doppelseitig klebenden Material auf Alu-Offsetplatten aufgezogen werden. Der Klebstoff darf nicht durch Wasser anlösbar sein. Bereits vor dem Aufziehen ist die Gummituchoberfläche mit Lösemittel-Reinigern fettfrei zu machen, und Farbreste und ähnliches sind zu entfernen. Stößt die Gummituchoberfläche des aufgezogenen Tuches Wasser perlig ab, so wird vor der Reinigung mit Schlämmkreide eine ca. 10%ige Phosporsäurelösung aufgebracht, die ungefähr 2 Minuten einwirken soll. Anschließend ist wieder mit Wasser klar zu spülen.Blankets that were previously used for printing and are now to be used for painting can be attached to aluminum offset plates with adhesive or double-sided adhesive material. The adhesive must not be soluble in water. The rubber blanket surface must be made grease-free with solvent cleaners even before opening, and paint residues and the like must be removed. If the rubber blanket surface of the drawn-on cloth repels pearly water, an approx. 10% phosphoric acid solution is to be applied before cleaning with chalk, which should take effect for about 2 minutes. Then rinse again with water.
Die Präparation der gutgereinigten Gummituchoberflächen mit den sensibilisierten Kopierschichten kann auf verschiedene Art erfolgen.
- 1.) Aufschleudern der Kopierschicht bei 100 bis 150 Umdrehungen in der Minute auf eine nasse Gummituchoberfläche und anschließende Trocknung, Kopierschicht und Gummituch sollen dabei nicht wärmer als 50°C werden.
- 2.) Aufgießen der Kopierschicht auf eine schräggestellte nasse Gummituchoberfläche, wobei der Überschuß ablaufen kann. Anschließend erfolgt Trocknung mit Warmluft wie oben.
- 3.) Aufbringen einer Kopierschicht mit einem weichen Schwamm auf die nach der Reinigung getrocknete Gummituchoberfläche, diese Schicht muß ebenfalls anschließend wie oben gut getrocknet werden.
- 1.) Spin the copy layer at 100 to 150 revolutions per minute onto a wet rubber blanket surface and subsequent drying, copy layer and rubber blanket should not be warmer than 50 ° C.
- 2.) Pour the copy layer on a slanted wet rubber blanket surface, the excess can run off. This is followed by drying with warm air as above.
- 3.) Apply a copy layer with a soft sponge on the rubber blanket surface dried after cleaning, this layer must also then dry well as above.
Ein weicher, kaum feuchter Viskoseschwamm soll ausschließlich für das Auftragen der Kopierschichten verwendet werden. Beim Auftragen der Kopierschichten mit dem Schwamm lassen sich Wischspuren nicht vermeiden. Diese sind jedoch ohne Bedeutung für eine Anhaltskopie.A soft, hardly damp viscose sponge should only be used for the application of the copy layers. Wiping marks cannot be avoided when applying the copying layers with the sponge. However, these are of no importance for a reference copy.
Nach der Belichtung, die sowohl mit einem Positiv als auch mit einem Negativ vorgenommen werden kann, wird entweder mit Wasser entwickelt und anschließend eingefärbt oder auch direkt mit einem Farbstoffkonzentrat passend zur Kopierschicht, entwickelt, anschließend klar gespült und getrocknet. Je nach dem ob ein Positiv oder ein Negativ verwendet wird, stellt sich ein auszuschneidender Klebestreifen z.B. als gehärtete, gefärbe Schicht oder als ausentwickelte Partie dar.After the exposure, which can be carried out with both a positive and a negative, is either developed with water and then colored or developed directly with a dye concentrate suitable for the copying layer, then rinsed clear and dried. Depending on whether a positive or a negative is used, an adhesive strip to be cut out, e.g. as a hardened, colored layer or as a developed section.
Belichtungsbeispiel: 5.000 Watt Metall-Halogenid-Lampe, Abstand 1 m, ca. 90 Sek., je nach Farbe der Gummituchoberfläche.Exposure example: 5,000 watt metal halide lamp, distance 1 m, approx. 90 seconds, depending on the color of the blanket surface.
Allgemein gilt, daß ca. das doppelte der Lichtmenge, die zur Belichtung einer vorbeschichteten Positivplatte für Offset benötigt würde, verwendet wird.In general, approximately twice the amount of light that would be required to expose a precoated positive plate for offset is used.
Bei den Polyvinylalkohol-Kopierschichten handelt es sich um ungefärbte Schichten, so daß der Farbumschlag durch die Belichtung nicht sehr groß ist. Auch der Einsatz bereits vor dem Beschichten angefärbter Schichten bringt wegen der kräftigen Eigenfarbe des Untergrundes keinen gut sichtbaren Kontrast.The polyvinyl alcohol copying layers are undyed layers, so that the color change due to the exposure is not very great. Even the use of layers that have already been colored before coating does not provide a clearly visible contrast due to the strong inherent color of the substrate.
Es gibt zwei Methoden, die gehärtete Schicht einzufärben:
- 1.) Entwickeln mit einem Wasserstrahl (Brause) bis die ungehärtete Schicht restlos entfernt ist. Ablaufenlassen des Wassers und Nachgießen mit Farbbad-Konzentrat (Einwirkungsdauer ca. 1 bis 2 Minuten), anschließend mit Wasser klarspülen und trocknen.
- 2.) Nach dem Belichten reichlich Farbbad-Konzentrat direkt unverdünnt aufgießen und mit dem Wattebausch oder weichem Tampon über die gesamte Oberfläche verteilen, ca. 1 bis 2 Minuten einwirken lassen, anschließend mit wasser klarspülen und trocknen.
- 1.) Develop with a water jet (shower) until the uncured layer is completely removed. Allow the water to run off and pour with a dye bath concentrate (exposure time approx. 1 to 2 minutes), then rinse with water and dry.
- 2.) After exposure, pour in plenty of dye bath concentrate undiluted and spread over the entire surface with a cotton ball or soft tampon, leave to work for approx. 1 to 2 minutes, then rinse with water and dry.
Nur geschleuderte oder gegossene Kopierschichten ergeben eine sehr gleichmäßige Einfärbung. Aufgewischte Kopierschichten werden auch nach dem Einfärben noch etwas streifig aussehen, sind aber für den vorgesehenen Zweck einer Anhaltskopie zum Ausschneiden lackfreier Klebelaschen vollauf ausreichend.Only thrown or cast copy layers result in a very even coloration. Wiped-up copy layers will still look a bit streaked after inking, but are completely sufficient for the intended purpose of a reference copy for cutting out paint-free adhesive tabs.
Zum Kopieren kann das Gummituch entweder auf eine AluDruckplatte d.h. also einen Metallträger mittels Klebstoff oder beidseitig klebender Folie aufgezogen werden oder es können auch ein käuflich zu erwerbendes selbstklebendes Gummituch oder mehrere Teilstücke direkt auf eine geeignete Trägerplatte geklebt werden.For copying, the rubber blanket can either be placed on an aluminum printing plate, i.e. Thus, a metal carrier can be attached using an adhesive or a double-sided adhesive film, or a self-adhesive rubber blanket or several parts that can be purchased can also be glued directly onto a suitable carrier plate.
Geeignet ist auch das Beschichten und Kopieren auf ein mit der gleichen Kraft gespanntes Gummituch, wie sie zum Spannen eines Gummituches auf einem Gummituchzylinder benötigt wird.Coating and copying onto a rubber blanket tensioned with the same force as is required for tensioning a rubber blanket on a rubber blanket cylinder is also suitable.
Ferner können bei der Beschichtung auf ein flachliegendes, weder gespanntes noch aufgeklebtes Gummituch Kopiervorlagen verwendet werden, die in Druckumfangsrichtung, d.h. Laufrichtung des Bedruckstoffes durch die Druckmaschine, um soviel Prozent in der Umfangsrichtung verkleinert wurden, wie die Dehnung des zum Lackieren verwendeten Gummituches beim Aufspannen auf den Zylinder beträgt, je nach Gummituchtyp ca. zwischen 1 bis 3 %.Furthermore, when coating on a flat, neither stretched nor glued-on blanket, copying templates can be used which extend in the circumferential direction, i.e. Direction of travel of the printing material through the printing machine, reduced by as much as percent in the circumferential direction, as the stretching of the rubber blanket used for varnishing when stretching on the cylinder is between 1 and 3% depending on the type of blanket.
Welche der hier geschilderten Methoden zur Lokalisierung der auszuschneidenden, nicht mit zu lackierenden Stellen eingesetzt wird, hängt weitgehend von der vorhandenen Spannvorrichtung des zum Lackieren eingesetzten Formzylinders ab.Which of the methods described here is used to localize the areas to be cut out and not to be painted depends largely on the existing clamping device of the forme cylinder used for painting.
Geeignet sind auch sogenannte Wipe-on-Kopierschichten. Diese Kopierschichten werden nur mit einem Schwamm auf die gereinigte, trockene Oberfläche aufgewischt, sie werden nicht geschleudert oder gegossen. Die Wipe-on-Kopierschicht arbeitet mit Diazosalzen und nicht mit Bichromat als lichtempfindlichen Bestandteil.So-called wipe-on copying layers are also suitable. These copy layers are only wiped onto the cleaned, dry surface with a sponge, they are not spun or poured. The wipe-on copy layer works with diazo salts and not with bichromate as a light-sensitive component.
Für die Kopiervorlagen gilt das bisher erwähnre in gleicher Weise . Zur Entwicklung der belichteten Schicht wird ein Lackentwickler eingesetzt. Wipe-on-Kopierschichten bzw. Lackentwickler sind z.B. unter "Neganol-Verfahren" bekannt geworden. Auch mit diesem Kopierprozeß ist eine Anhaltskopie auf Gummituchoberflächen möglich.The same applies to the copy templates mentioned so far. A coating developer is used to develop the exposed layer. Wipe-on copy layers or paint developers are e.g. known as the "Neganol process". With this copying process a reference copy on blanket surfaces is also possible.
