Definitions
- the invention relates to a printing form for planographic printing with a hydrophilic surface, to which surface elements that accept ink under the influence of heat and pressure can be transferred.
- DE-32 48 178 A1 describes a printing form of this type which can be deleted and can be rewritten within the printing machine for an image change.
- hydrophobic surface elements are transferred to the hydrophilic surface of the printing form by means of a thermal print head and a thermal transfer film under the action of heat and pressure.
- the thermal print head generates selective heat in order to apply individual ink-accepting dots to the hydrophilic surface with the help of the thermal transfer film.
- the invention has for its object to develop a printing form of the type mentioned in such a way that an accurate transfer of images or lettering is possible.
- the invention is based on the knowledge that when the selective heat is transferred by means of the thermal print head, the heat flows away too quickly via the metal printing form. The temperature generated at certain points is thus sufficient not enough to remove the layer of the thermal transfer ribbon provided for the application of the hydrophobic or oleophilic surface elements on the printing form.
- the measure according to the invention prevents the heat generated by the thermal print head from flowing away quickly, and ensures that the layer in the thermal transfer ribbon is transferred to the print medium in a precise and point-specific manner in each case.
- the printing form cylinder or the printing form plate is made of a material with heat-insulating properties and a hydrophilic character. This is the simplest solution in terms of production technology, the surface of the forme cylinder or the forme plate being the printing form.
- these can be produced from any material and coated with a material with heat-insulating properties and hydrophilic character.
- one or the other embodiment mentioned above can be combined with a thin metal layer which is applied to the material.
- This metal layer which with a conventional method, for. B. applied by vapor deposition offers a good basis for the introduction of the oleophilic areas. Due to the chosen thickness of a few ⁇ m, approximately in the range of 10 ⁇ m of the metal layer, is on on the other hand ensures that there is no lateral heat discharge.
- aluminum can be used for the metal layer.
- Ceramic materials, plastics and metal oxides can be used as the heat-insulating material. If the material forms the printing surface of the printing form, then the material must also have a good hydrophilic character. They should also be resistant to circulation in order to prevent premature wear of the printing form.
- a printing form cylinder (10) is shown in cross section, which consists of a core (11) of any material, e.g. B. iron and a coated printing form, which in turn consists of a composite (12) and (13).
- the inner layer (12) of the printing form consists of a material that is good heat insulation, such as. B. a plastic, a metal oxide or ceramic material.
- the second layer (13) is applied very thinly on the heat-insulating layer (12) of the printing form approximately in the range of 10 ⁇ m.
- This second layer (13) consists of a metal which has a hydrophilic character, e.g. B. aluminum, aluminum oxide, chrome.
- This composite (12, 13) forming the printing form thus has a surface (14) which has a hydrophilic character and is overall heat-insulating, the outer metal layer (13), due to its small thickness, hardly being able to contribute to heat transport.
- Such a printing cylinder (10) is assigned an image information transmission unit (15) within the printing press, via which the image information is transferred to the surface of the printing form (12, 13) in the form of ink-accepting surface elements.
- the transmission unit (15) consists of a film (16) with a thermo or electrothermal sensitive coating, the oleophilic, d. h., has ink-accepting properties, and a printhead (17), which can be a heating element, an electrode, an energy beam or any other heat-generating unit.
- the print head (17) is controlled via the corresponding image signals (18) in such a way that it introduces heat and pressure onto the film (16) at every pixel and thus a selective transfer of the coating of the film onto the surface (14) the printing form (12, 13) transfers where it remains anchored.
- the film (16) is transported via reserve and roll cylinders (19) and (20).
- the layer applied to the printing form (12, 13) in this way forms the ink-accepting surface elements.
- the printing form or the printing form cylinder can be formed in various ways. Instead of the layers with different properties, the entire printing form cylinder can be produced homogeneously from a material which has both properties, namely the thermal insulation and the hydrophilic character. However, only the printing form cylinder surface can also be coated with such a material. It is important in any case that the surface of the printing form or the printing form cylinder is water-accepting and that the over heat introduced into the printhead is preferably not dissipated. In this way it is ensured that the heat layer is transferred to the printing form surface with certainty with the appropriate metered introduction of heat and is also precisely delimited.
Abstract
Druckform (12, 13) für den Flachdruck, die eine wasserannehmende Oberfläche (14) hat, auf die unter Wärme- und Druckeinwirkung (17) farbannehmende Flächenelemente übertragbar sind. Um eine sichere und konturenmäßig genau abgegrenzte Übertragung derartiger Schichten zu gewährleisten, wird vorgeschlagen, die Druckform aus einem Werkstoff herzustellen, der wärmeisolierend und an der Oberfläche wasserannehmend ist. Dadurch wird eine zu schnelle Ableitung der mittels eines Druckkopfes (17) eingeleiteten Wärme verhindert, die eine genau abgegrenzte und überhaupt die Übertragung einer oleophilen Schicht stören könnte.Printing form (12, 13) for planographic printing, which has a water-accepting surface (14), to which surface-accepting ink elements can be transferred under the action of heat and pressure (17). In order to ensure reliable and precisely defined transfer of such layers, it is proposed to produce the printing form from a material that is heat-insulating and water-absorbing on the surface. This prevents the heat introduced by means of a printhead (17) from being dissipated too quickly, which heat could be delimited and could interfere with the transmission of an oleophilic layer.
Description
Die Erfindung bezieht sich auf eine Druckform für den Flachdruck mit einer hydrophilen Oberfläche, auf die unter Wärme- und Druckeinwirkung farbannehmende Flächenelemente übertragbar sind.The invention relates to a printing form for planographic printing with a hydrophilic surface, to which surface elements that accept ink under the influence of heat and pressure can be transferred.
In der DE-32 48 178 A1 ist eine Druckform dieser Art beschrieben, die löschbar ist und innerhalb der Druckmaschine für eine Bildänderung umschreibbar ist. Bei der bekannten Vorrichtung werden mittels eines Wärmedruckkopfes und einer Thermotransferfolie unter Wärme- und Druckeinwirkung hydrophobe Flächenelemente auf die hydrophile Oberfläche der Druckform übertragen. Durch den Wärmedruckkopf wird punktuelle Wärme erzeugt, um mit Hilfe der Thermotransferfolie einzelne farbannehmende Punkte auf die hydrophile Oberfläche aufzubringen.DE-32 48 178 A1 describes a printing form of this type which can be deleted and can be rewritten within the printing machine for an image change. In the known device, hydrophobic surface elements are transferred to the hydrophilic surface of the printing form by means of a thermal print head and a thermal transfer film under the action of heat and pressure. The thermal print head generates selective heat in order to apply individual ink-accepting dots to the hydrophilic surface with the help of the thermal transfer film.
Es hat sich aber herausgestellt, daß die so eingebrachten Bereiche nicht homogen hydrophob sind und außerdem keine klaren Abgrenzungen aufweisen.However, it has been found that the areas introduced in this way are not homogeneously hydrophobic and, moreover, have no clear boundaries.
Der Erfindung liegt die Aufgabe zugrunde, eine Druckform der eingangs genannten Art dahingehend weiter zu entwickeln, daß eine genaue Übertragung von Bildern bzw. Schriftzügen möglich ist.The invention has for its object to develop a printing form of the type mentioned in such a way that an accurate transfer of images or lettering is possible.
Die Aufgabe wird erfindungsgemäß durch die im Anspruch 1 gekennzeichneten Merkmale gelöst.The object is achieved by the features characterized in claim 1.
Der Erfindung liegt die Erkenntnis zugrunde, daß bei der Übertragung der punktuellen Wärme mittels des Wärmedruckkopfes die Wärme zu schnell über die Metalldruckform abfließt. Damit reicht die punktuell erzeugte Temperatur nicht aus, um die für das Aufbringen der hydrophoben bzw. oleophilen Flächenelemente auf der Druckform vorgesehene Schicht des Thermotransferbandes vom Band abzulösen.The invention is based on the knowledge that when the selective heat is transferred by means of the thermal print head, the heat flows away too quickly via the metal printing form. The temperature generated at certain points is thus sufficient not enough to remove the layer of the thermal transfer ribbon provided for the application of the hydrophobic or oleophilic surface elements on the printing form.
Durch die erfindungsgemäße Maßnahme wird ein schnelles Abfließen der durch den Wärmedruckkopf erzeugten Wärme verhindert und eine punktweise, genau abgegrenzte Übertragung der Schicht im Thermotransferband auf den Druckträger in jedem Fall sichergestellt.The measure according to the invention prevents the heat generated by the thermal print head from flowing away quickly, and ensures that the layer in the thermal transfer ribbon is transferred to the print medium in a precise and point-specific manner in each case.
Gemäß einer ersten Ausgestaltung der Erfindung ist der Druckformzylinder bzw. die Druckformplatte aus einem Werkstoff mit wärmeisolierenden Eigenschaften und hydrophilem Charakter hergestellt. Dieses ist die fertigungstechnisch einfachste Lösung, wobei die Oberfläche des Formzylinders bzw. der Formplatte die Druckform darstellt.According to a first embodiment of the invention, the printing form cylinder or the printing form plate is made of a material with heat-insulating properties and a hydrophilic character. This is the simplest solution in terms of production technology, the surface of the forme cylinder or the forme plate being the printing form.
Um die freie Wahl des Materials für den Zylinder oder die Platte nicht einschränken zu müssen, können diese aus einem beliebigen Material hergestellt werden und mit einem Werkstoff mit wärmeisolierenden Eigenschaften und hydrophilem Charakter beschichtet werden.In order not to have to restrict the free choice of the material for the cylinder or the plate, these can be produced from any material and coated with a material with heat-insulating properties and hydrophilic character.
Es hat sich ferner gezeigt, daß die eine oder die andere vorstehend erwähnte Ausgestaltung mit einer dünnen Metallschicht kombiniert werden kann, die auf den Werkstoff aufgebracht wird. Diese Metallschicht, die mit einem üblichen Verfahren, z. B. durch Aufdampfen aufgebracht wird, bietet eine gute Grundlage für die Einbringung der oleophilen Bereiche. Durch die gewählte Dicke von einigen µm, etwa im Bereich von 10 µm der Metallschicht, wird auf der anderen Seite gewährleistet, daß ein seitlicher Wärmeabfluß nicht stattfindet. Für die Metallschicht kann beispielsweise Aluminium verwendet werden.It has also been shown that one or the other embodiment mentioned above can be combined with a thin metal layer which is applied to the material. This metal layer, which with a conventional method, for. B. applied by vapor deposition offers a good basis for the introduction of the oleophilic areas. Due to the chosen thickness of a few µm, approximately in the range of 10 µm of the metal layer, is on on the other hand ensures that there is no lateral heat discharge. For example, aluminum can be used for the metal layer.
Als wärmeisolierenden Werkstoff können Keramikmaterialien, Kunststoffe sowie Metalloxide verwendet werden. Wenn der Werkstoff die druckende Fläche der Druckform bildet, dann muß der Werkstoff zusätzlich einen guten hydrophilen Charakter besitzen. Sie sollten auch auflagenbeständig sein, um einer vorzeitigen Abnutzung der Druckform vorzubeugen.Ceramic materials, plastics and metal oxides can be used as the heat-insulating material. If the material forms the printing surface of the printing form, then the material must also have a good hydrophilic character. They should also be resistant to circulation in order to prevent premature wear of the printing form.
In der Zeichnung ist ein Ausführungsbeispiel schematisch dargestellt.In the drawing, an embodiment is shown schematically.
Es ist ein Druckformzylinder (10) im Querschnitt dargestellt, der aus einem Kern (11) beliebigen Materials, z. B. Eisen und einer darauf überzogenen Druckform besteht, die ihrerseits aus einem Verbund (12) und (13) besteht. Die innere Schicht (12) der Druckform besteht aus einem Werkstoff, der gut wärmeisolierend ist, wie z. B. ein Kunststoff, ein Metalloxid oder Keramikmaterial. Auf der wärmeisolierenden Schicht (12) der Druckform ist die zweite Schicht (13) sehr dünn etwa im Bereich von 10 µm aufgetragen. Diese zweite Schicht (13) besteht aus einem Metall, das hydrophilen Charakter hat, z. B. Aluminium, Aluminiumoxid, Chrom. Dieser die Druckform bildende Verbund (12, 13) hat somit eine Oberfläche (14), die hydrophilen Charakter hat und ist insgesamt wärmeisolierend, wobei die äußere Metallschicht (13) aufgrund ihrer geringen Dicke kaum zu einem Wärmetransport beitragen kann.A printing form cylinder (10) is shown in cross section, which consists of a core (11) of any material, e.g. B. iron and a coated printing form, which in turn consists of a composite (12) and (13). The inner layer (12) of the printing form consists of a material that is good heat insulation, such as. B. a plastic, a metal oxide or ceramic material. The second layer (13) is applied very thinly on the heat-insulating layer (12) of the printing form approximately in the range of 10 μm. This second layer (13) consists of a metal which has a hydrophilic character, e.g. B. aluminum, aluminum oxide, chrome. This composite (12, 13) forming the printing form thus has a surface (14) which has a hydrophilic character and is overall heat-insulating, the outer metal layer (13), due to its small thickness, hardly being able to contribute to heat transport.
Einem derartigen Druckzylinder (10) ist eine Bildinformations-Übertragungseinheit (15) innerhalb der Druckmaschine zugeordnet, über die die Bildinformation in Form von farbannehmenden Flächenelementen auf die Oberfläche der Druckform (12, 13) übertragen wird.Such a printing cylinder (10) is assigned an image information transmission unit (15) within the printing press, via which the image information is transferred to the surface of the printing form (12, 13) in the form of ink-accepting surface elements.
Die Übertragungseinheit (15) besteht aus einer Folie (16) mit einer thermo- oder elektrothermosensitiven Beschichtung, die oleophile, d. h., farbannehmende Eigenschaften hat, sowie einem Druckkopf (17), der ein Heizstab, eine Elektrode, ein Engeriestrahl oder jede andere wärmeerzeugende Einheit sein kann.The transmission unit (15) consists of a film (16) with a thermo or electrothermal sensitive coating, the oleophilic, d. h., has ink-accepting properties, and a printhead (17), which can be a heating element, an electrode, an energy beam or any other heat-generating unit.
Zur Übertragung einer Bildinformation wird der Druckkopf (17) über die entsprechenden Bildsignale (18) so gesteuert, daß er bei jedem Bildpunkt Wärme und Druck auf die Folie (16) einleitet und damit eine punktuelle Übertragung der Beschichtung der Folie auf die Oberfläche (14) der Druckform (12, 13) überträgt, wo sie verankert bleibt. Die Folie (16) wird dabei über Reserve- und Abrollzylinder (19) bzw. (20) transportiert. Die auf die Druckform (12, 13) auf diese Weise aufgebrachte Schicht bilden die farbannehmenden Flächenelemente.To transmit image information, the print head (17) is controlled via the corresponding image signals (18) in such a way that it introduces heat and pressure onto the film (16) at every pixel and thus a selective transfer of the coating of the film onto the surface (14) the printing form (12, 13) transfers where it remains anchored. The film (16) is transported via reserve and roll cylinders (19) and (20). The layer applied to the printing form (12, 13) in this way forms the ink-accepting surface elements.
Die Bildung der Druckform oder des Druckformzylinders kann auf verschiedene Art und Weise erfolgen. Anstelle der Schichten mit unterschiedlichen Eigenschaften kann der gesamte Druckformzylinder homogen aus einem Werkstoff hergestellt werden, der beide Eigenschaften, nämlich die Wärmeisolierung und den hydrophilen Charakter aufweist. Es kann aber auch lediglich die Druckformzylinderoberfläche mit einem derartigen Werkstoff beschichtet sein. Wichtig ist in jedem Fall, daß die Oberfläche der Druckform bzw. des Druckformzylinders wasserannehmend ist und daß die über den Druckkopf eingeleitete Wärme möglichst nicht abgeleitet wird. Auf diese Weise wird sichergestellt, daß unter entsprechend dosierter Wärmeeinleitung eine Übertragung der Thermoschicht auf die Druckformoberfläche mit Sicherheit erfolgt und zudem auch genau abgegrenzt ist.The printing form or the printing form cylinder can be formed in various ways. Instead of the layers with different properties, the entire printing form cylinder can be produced homogeneously from a material which has both properties, namely the thermal insulation and the hydrophilic character. However, only the printing form cylinder surface can also be coated with such a material. It is important in any case that the surface of the printing form or the printing form cylinder is water-accepting and that the over heat introduced into the printhead is preferably not dissipated. In this way it is ensured that the heat layer is transferred to the printing form surface with certainty with the appropriate metered introduction of heat and is also precisely delimited.
Die vorstehend im Zusammenhang mit einem Formdruckzylinder gemachten Ausführungen gelten selbstverständlich auch im gleichen Maße für Druckformplatten.The statements made above in connection with a form printing cylinder naturally also apply to printing form plates to the same extent.
