Definitions
- the invention relates to a base material for a printing form, in particular planographic printing plate or printing plate, in particular planographic printing plate, and / or for a printing blanket, in particular rubber blanket, in particular compressible or incompressible rubber blanket, and / or for another surface involved in the printing process during printing, in particular in offset printing, as well as a printing device containing this substructure material, in particular offset printing device and a printing blanket for printing uneven substrates, corrugated cardboard.
- a printed image is applied to a printing medium inside the printing unit by rolling cylinders and drums that transmit and transfer the printing medium.
- the print image is generated on a printing form or printing plate and, if necessary, passed on to the printing material via a transfer cylinder.
- BESTATIGUNGSKOPIE In a direct printing process such as high pressure, for example the flexographic printing process, a printing form or printing plate provided with raised printing surfaces is used for this purpose, by means of which the printed image can be applied directly to the printing material.
- Offset printing an indirect printing process, is a widespread planographic printing process in which the print image in the form of the color material is transferred from a printing form or printing plate to a transfer cylinder, which is referred to as a blanket cylinder.
- the surface of the printing form or printing plate is provided with lipophilic, that is to say water-repellent, areas in accordance with the image to be printed, so that the lipophilic ink applied by an inking unit adheres there.
- the printing image is then transferred from the printing blanket cylinder, more precisely from a printing blanket which is clamped onto the printing blanket cylinder and explained below, to the printing material.
- the print image is transferred from a printing form to a transfer cylinder, which is referred to as a blanket cylinder. From this the print image is then transferred to the printing material.
- a flexible layer is usually applied to the blanket cylinder.
- a so-called printing blanket or rubber blanket is used for this. This blanket is dimensionally stable in its plane of expansion, but is deformable transversely to it. It can also be compressible to a certain extent in the direction of its thickness. For this purpose, it is known that compressible layers are provided within a printing blanket.
- a flexible layer is usually applied to the blanket cylinder;
- a so-called printing blanket or rubber blanket is used for this purpose, which is essentially dimensionally stable in its plane of expansion, but is deformable transversely to it.
- the printing blanket can also be compressible to a certain extent in the direction of its thickness; for this purpose it is known that compressible layers are provided within the printing blanket. From this blanket, the printing is now
- Blankets or the printing blankets used in offset printing are required in the offset printing process when transferring the print image, above all to compensate for unevenness in the surface of the printing substrate. Since the printing forms or printing plates for offset printing are usually formed from thin sheets or foils, they cannot adapt to the surface structure of the printing material to a sufficient extent.
- a printing blanket must be pressed against the counter-pressure cylinder by the blanket cylinder against the impression cylinder with a relatively high contact pressure in order to adapt it to the surface structure of the printing substrate; this cannot be avoided by using so-called compressible printing blankets because they only have a higher deformability than normal printing blankets, but also require a comparatively high contact pressure.
- compressible printing blankets because they only have a higher deformability than normal printing blankets, but also require a comparatively high contact pressure.
- corrugated cardboard when printing on corrugated boxes, there is a special problem that is related to the internal structure of corrugated boxes. Since a corrugated connection layer is provided between two cover layers in corrugated cardboard to make it lighter, a corrugated cardboard is not a homogeneous material. The cover layers used on the top and bottom of such corrugated cardboard are only at certain points or lines and are offset on both sides connected to each other by means of a corrugated intermediate layer. When a corrugated cardboard is loaded, uneven conditions arise across the surface; in particular, each cover layer is flexible in the areas between the connection points with the corrugated intermediate layer and can therefore dodge in these areas when loaded. As a result, the stress in a printing process results in relatively unfavorable conditions for uniform printing.
- the printing form or printing plate is enabled to follow unevenness on the surface of the printing material to a limited extent.
- a deterioration in the print quality is accepted, which inevitably results from the deformation of the printing form or printing plate; this is also related to the usually very inhomogeneous distribution of printing and non-printing areas on a printing form or printing plate; in addition, registering the printing forms or printing plates for the different printing inks is very difficult.
- compressible printing blankets a procedure that is not comparable with the above-mentioned method of supporting a printing form or printing plate is used.
- the compressible printing blanket allows deformations by reducing the thickness only under comparatively high pressure.
- the one to adapt to the surface structure of the corrugated cardboard necessary deformations in such printing blankets would inevitably lead to the destruction of the corrugated cardboard in the printing process before the printing blanket could deform sufficiently.
- no method is known by means of which a highly uniform pressure distribution is possible in offset printing when processing a corrugated cardboard in a printing process.
- the disadvantages and shortcomings described above by way of example can be generalized insofar as the rotary cylinders involved in the printing process of the offset process are generally made of hard material, such as metal.
- the printing form or printing plate is also made of solid material, such as metal, such as aluminum, zinc or the like, or of plastic. Due to the dimensional stability of these materials, unevenness and imbalance can occur which negatively affect the printed image.
- the rigidity of the materials mentioned means that changing a printing form or printing plate can be difficult insofar as there is no flexibility for the compensation of tolerances.
- the present invention is based on the object of improving an offset printing machine of the type described at the outset in such a way that an improved printed image is obtained, that it is possible to change printing plates more quickly and easily and that high-quality printed images can be printed on uneven substrates , especially on corrugated cardboard. Therefore, it aims

- the substructure material as an interchangeable, radially elastically deformable composite or radially to the respective drum, unevenness, dimensional tolerances and imbalances in the components involved in the printing process can be compensated. In this way, an equalization and thus an improvement in the printed image can be achieved.
- the base material according to the present invention which can be formed in the composite as a stretchable underlay, in particular as a stretchable printing plate underlay or printing plate underlay and / or as a stretchable printing blanket underlay, surprisingly, in addition to increasing the printing quality, the retrofitting of an offset printing device is also facilitated .
- the base material ensures, due to its (radial) elasticity, that any dimensional tolerances between the printing form or printing plate and the form cylinder are compensated for.
- the printing form or printing plate can thus be fixed with a firm fit on the form cylinder.
- the flexible substructure material under the printing blanket enables an increased deformation of the printing blanket radially to the printing blanket cylinder during the printing process.
- the deformation is possible with a lower force than the deformation of a compressible blanket.
- the length stability of the printing blanket is maintained, which ensures good print quality and enables printing on an uneven surface, such as on corrugated cardboard, in offset printing.

- the compressible layer By connecting the compressible layer with an incompressible layer, it is ensured at the same time that the substructure material can be handled in an advantageous manner, so that the substructure material can in particular be attached with sufficient stability to one of the cylinders involved in the printing process.
- the connection of the compressible layer with an incompressible layer gives the composite material an overall increased stability, so that forces introduced into the compressible layer can only cause a limited deformation of the substructure material.
- the compressible layer of the substructure material can be a microcellular, preferably open-pore material.
- a cellular structure like a foam allows the compressibility of the material to be adjusted to a certain extent; If the microcellular compressible layer is expediently formed from polyurethane foam, a high level of durability is associated with the desired compressibility.
- the base material can be optimally selected with regard to properties other than compressibility, for example with regard to its tear resistance and / or its chemical resistance.
- the compression behavior of the entire material is generated by its cellular structure, which can be set by the user to a certain extent depending on the respective requirements and regardless of the base material.
- the incompressible layer which according to an inventive development is designed as a dimensionally stable carrier layer, in particular as a dimensionally stable plate or film, can advantageously be wholly or partly at least one plastic, preferably polyester.
- a material is inexpensive, of high durability and at the same time flexible in terms of bending or dimensionally stable against tension. Furthermore, such a material can be easily combined with other materials to form a composite material.
- the substructure material can contain one or more further layers, which can in particular contain an adhesive material, a filler material and / or other auxiliary materials.
- an adhesive material serves to connect adjacent layers, that is to say in particular to connect an incompressible layer to a compressible layer.
- Filling materials are used to give the substructure material a desired volume (-> layer thickness) without otherwise influencing the material properties.
- layers of other auxiliary materials can be provided which, for example, improve the connection to the supporting cylinder, to the printing form or printing plate, to the printing blanket or the like, or to make certain outer surfaces available.
- the substructure material contains at least two compressible layers, these preferably having a different structure with regard to the base material and / or with regard to the structure (porosity) and / or a different thickness.
- the behavior of the substructure material when pressure is applied can be controlled. For example, a thicker or more compressible layer in direct contact with the printing form or printing plate can achieve good local absorption of pressure and force peaks, whereas a firmer (thinner) material in a lower layer ensures that greater forces are introduced spread over a larger area.
- the substructure material contains at least two incompressible layers, which in turn can in particular have a different structure with regard to the base material and / or the structure and / or a different thickness.
- These measures can also be used to control the behavior of the substructure material.
- the layers that are in direct contact with carrier elements can be optimally designed for connection to them; this means that these materials have, for example, sufficient (tear) strength and / or sufficient thickness for attachment to a cylinder.
- layers located in the interior of the substructure material can be minimized to a thickness that is sufficient to be able to fulfill their carrier function within the overall composite.
- the total (layer) thickness of the flat substructure material composed of at least two layers can be of the order of magnitude about 0.5 millimeters to about 4 millimeters, in particular from about 1.5 meters to about 2.5 millimeters, move. With such layer thicknesses, existing pressure equipment can be retrofitted with the substructure material without or without significant changes in order to compensate for unevenness in the desired manner.

- substructure materials 100 'with a thickness of about 0.5 millimeters to about 3.00 or 4.00 millimeters are suitable for the application mentioned.
- the selection of substructure materials 100 'with a thickness of approximately 1.00 millimeters to approximately 2.00 millimeters is preferred.
- the foam is reversibly compressible over many cycles of action To prefer foam. In this case, an open-cell foam is preferably used. This is easier to compress than the known closed-cell layers in printing blankets.
- the special printing blanket 13, 70 can preferably be produced from a conventional printing blanket in that the base layer 17 'is also built into the printing blanket.
- the open-cell foam mentioned is preferably applied to an existing stretch-resistant textile layer or a different type of base or base layer of the printing blanket.
- the active layer 13 'of the printing blanket can in turn be applied to the foam. This has the advantage that, with the tensile strength of the special printing blanket 70 remaining the same, a greatly improved flexibility in the transverse direction to the area extension of the special printing blanket 70, in particular in its active layer 13 ′, is achieved compared to a conventional printing blanket. (Fig. 4)
- a simple improvement in the mode of operation of the special printing blanket 70 can be achieved in that only a part of a conventional printing blanket is laminated onto the substructure material 100 'or the underlayer. For this purpose, part of the mostly textile lower layers that produce the tensile strength of the printing blanket can be separated from a conventional printing blanket. This ensures the dimensional stability of the printing blanket in the working plane is sufficiently ensured. A printing blanket which is weakened in this way in its stiffness transversely to the active plane can now be applied as active layer 13 'to the base material 100' or the cover layer 16 'of the lower layer. A special printing blanket 70 of the type described above can thus be produced in a simple manner and can be clamped onto a printing blanket cylinder 12 in an equally simple manner.
- a reinforcement can be provided in the area of the tensioning edges of the special printing blanket 70 in such a way that both the clamping and the use of the special printing blanket 70 are improved during the printing process.
- the special printing blanket 70 is flattened at its ends after joining the active layer 13 ′ and the lower layer to a thickness dimension suitable for the tensioning devices present in a printing blanket cylinder 12.
- the clamping ends produced in this way can also be provided with a reinforcement in the form of a metal rail or other suitable reinforcements.
- the front edges of the tensioning ends of the special printing blanket 70 can be provided with a seal.
- a special printing blanket 70 which contains a voluminous working area made of a flexible active layer 13 'with a suitably compressible lower layer. Furthermore, the special printing blanket 70 can be tensioned on a printing blanket cylinder 12 like a conventional printing blanket of known thickness.
- the construction of the voluminous special printing blanket 70 described can be varied over a wide range, the starting materials (conventional or other printing blanket, underlayer or built-in layer made of open-cell foam) and their construction forming the general conditions.
- the connection between the active layer 13 'and the expandable base layer 17' or the installation of the foam in a printing blanket between the active layer 13 'and an additional, if necessary conventional, base layer for producing the special printing blanket 70 is carried out using known conventional means.
