Definitions
- the present invention relates to a method for obtaining image information an illustrated printing form and a device for carrying out the Process. Furthermore, the invention relates to a printing press, in which such Method finds application, in particular in the wet offset web-fed rotary printing, especially in newspaper edition printing.
- Newspapers are mainly produced in wet offset.
- Printing machines like them
- the present invention preferably includes Printing units with blanket cylinders, plate cylinders, inking units and Dampening systems.
- a tensioned on a printing form cylinder printing plate has a Surface mostly in the form of a top layer, in the illustrated state hydrophilic (water-friendly) and hydrophobic (water-repellent) or lipophilic Has areas.
- the printing form is formed by a printing plate, which is mounted on a plate cylinder designed as a plate cylinder.
- the printing form has imagewise applied lipophilic areas.
- the non-picture places are hydrophilic and bind water stronger than those used for printing Colour.
- the lipophilic areas repel water and therefore have a color-friendly effect.
- any surface can be used for the offset process, which in hydrophilic and hydrophobic or lipophilic areas can be divided.
- An imaging is understood below to mean a process in which on the Printing form is acted on the points that form the pixels, so that on the Printing form by forming hydrophilic and lipophilic areas a the Print image corresponding template is generated.
- Under a deletion becomes in the sense of the Invention understood a process in which the printing plate preferably not image-dependent, but is treated over the entire surface in such a way that in the imaging applied image information, that is, the printed image is removed again.
- suitable printing plates or printing plates exist a variety of Materials and procedures.
- print forms be made by laser ablation. In this case, either lipophilic areas under a hydrophilic layer or hydrophilic regions under a lipophilic layer exposed.
- e.g. with an ink jet process or with thermal diffusion imagewise applied material to a surface and thereby an offset printing form be created.
- the relevant for the imaging of the printing form process can either done in a separate plant or inside the printing press.
- the object of the present invention is to provide a method and a device create to easily preserve the image information of a printing forme enable and thus allow the printing of long runs.
- a preferred application relates to the preservation of Image information of erasable printing forms, preferably in offset printing, still more preferably in wet offset printing.
- the image information of an imaged printing form is thereby maintained get that onto the imaged printing plate with the color transferred to it like that is acted that surface properties of the printing plate according to the Imaging received or refreshed.
- the advantage is that again writable printing form for maintaining a sufficient print quality not first deleted and then reimaged with fresh image information, but the Surface properties responsible for color transfer, print quality, etc. are preserved during production or refreshed.
- the inventive method thus allows high print runs at the same Print quality. Since the printing form used is not deleted and rewritten or can be replaced by another printing plate, production can preferably produced without interruption with the same print quality become.
- those responsible for the image formation become different hydrophobic and hydrophilic areas of the printing plate influenced so that the hydrophobic and hydrophilic properties of imagewise areas of the imaged Printing form with the ink transferred thereon according to the thickness of the Acting on the printing form can be modified, so that overall the imaging retained on the printing plate.
- Very particularly preferred are by the Exposure to the imaged printing form interfacial properties thereof which in turn has an influence on image transfer properties and / or Color properties of the imaged printing form may have, wherein the action This ensures that the achievable print quality remains essentially constant.
- the action takes place on the illustrated printing form during a production essentially with normal Printing speed rotating printing forme cylinder, so no slowing down the current production occurs.
- the impact can also during a comparatively short stoppage of production without the Imaging deleted and the printing form is reprinted.
- the Printing form cylinder turned comparatively slowly while the action on the Printing form to maintain the quality responsible for the print quality Surface properties of the printing form takes place.
- the effect on the printing plate during production is, for example, then possible if the image data forming the print image to actuators or Process means are transmitted in accordance with the transmitted image data specifically to the image locations or to the non-image areas of the printing form or the act hydrophobic or hydrophilic areas. Examples of such Mechanisms of action are described in the Handbook of Print Media by H. Kipphan, supra. described, so that omitted details for reasons of clarity can.
- the imagewise action is particularly preferably during production at essentially resting or only slowly rotating printing plate cylinder, there the currently known actuators only comparatively slowly to the printing plate can act.
- the Exposure during production essentially over the entire surface of the printing form.
- the image sites or hydrophobic sections of the printing form during the printing process are afflicted with a color layer, the non-image points, however not covered with printing ink.
- the Impact mechanism can be chosen such that the hydrophobic and hydrophilic Sections of the printing form due to the applied ink layer differently be influenced, wherein the applied ink layer for the required Differentiation of the action mechanism is exploited.
- optical radiation acts on a printing plate one that responds to optical radiation, so is the influence of optical radiation on the non-image places differently than on the picture places, because of the on the printing form Applied color layer, the radiation is filtered imagewise.
- full-surface irradiation of the printing form is thus due to the overlying Color layer automatically an imagewise different influence on the image areas and non-image areas of the printing form.
- the spectral width of the Absorption band and the frequency of the optical radiation used can be the imagewise conservation of the interface properties of the printing form optimally to the Adjust operating conditions.
- the aforementioned radiation absorption can also be used to reason local heating due to absorption in the color areas above the Image sites to suppress the hydrophilization of these areas.
- optical radiation with others Wavelengths are used, for example, with wavelengths in the visible Wavelength range or in the infrared wavelength range, as long as the optical Radiation of pigments or other constituents of the printing ink used, For example, of additives, is sufficiently absorbed.
- additives can z. B. absorb only in the UV range and thus have no influence on the print quality.
- a printing forme is used in which the surface permanent hydrophilization can be achieved, for example by Photocatalysis.
- a printing form is known by UV radiation can be made hydrophilic. This leads to an excitation of the atoms in one higher energetic state, which interacts with water molecules of the Environment allows. In the presence of water in the environment, for example of dampening water, it comes to a binding of the water at the surface of the Printing form, whereby this retains the hydrophilicity, even after the irradiation is interrupted.
- the wavelength of the optical irradiation, the Absorption wavelength of the ink and the width of the absorption of the color to Available can be changed by changing the wavelength of the light or using Additives to the color can be adjusted accordingly, for optimal imagewise Refreshment of the imaging with full-surface irradiation of the printing forme too enable.
- an electric field or an electrostatic potential can be applied to the Surface of the printing form are applied, for example by means of an in uniform, small distance to the surface of the printing plate attached High voltage electrode.
- an electric field or Electrostatic potential is different on image sites and non-image sites and can be exploited according to the invention.
- Additions can be made in the Wet offset printing process used to make dampening solution conductive, so that charges, which arise at non-inked portions of the printing plate surface, can be derived while the insulating, oily ink without such Addition prevents the discharge of charges.
- the insulating, oily remains Printing ink electrostatically charged.
- a imagewise action can be achieved, so that, for example, the color properties and / or the image transfer properties from the printing form to a downstream one Roller, for example blanket cylinder, imagewise modifiable.
- the surface of the printing form may contain ferroelectric materials, For example, ceramics, ceramic multilayer systems or polymers, such as are known for direct imaging systems of the prior art.
- ferroelectric materials For example, ceramics, ceramic multilayer systems or polymers, such as are known for direct imaging systems of the prior art.
- the ferroelectric material is usually in three excellent states, which are referred to as electrically positive, electrically negative and neutral and between where the material can be switched back and forth, the states are stable are.
- the ink layer adhering to the printing form may be in the form of a dielectric Be treated layer.
- the dielectric constant of the color layer can by dielectric additives are further enhanced.
- the acting dielectric Shift D different in image locations and non-image locations, so that despite full-surface application of an electrostatic potential or electric field a imagewise influencing the surface properties of the printing form are effected can imagewise to Farbhaftigenschaften and / or image transfer properties modify.
- this mechanism of action can also be used with other mechanisms of action be combined.
- the chemical substance in the form of a Liquid or as an additive to a liquid sprayed over the entire surface or by means of a Dampening be applied over the entire surface. Due to the imagewise applied Color layer enters the liquid only at the non-image areas with the surface of the Printing form in contact. If the printing form is chosen such that a hydrophilization the surface can be effected by photocatalysis or other optical effects, so the liquid required for the hydrophilization is at the non-image sites automatically available. By suitable irradiation can thus the Hydrophilization be obtained suitably at the non-image areas.
- Another example is the supply of airflow to the surface of the printing plate.
- the evaporation of Fountain be promoted, which rests on the non-image areas.
- the cooling effect is lower at the image points, though The ink evaporates less strongly, and stronger when the ink is light contains volatile substances.
- full-surface admission of the Druckformober Structure with the air flow can thus imagewise influencing the obtained for the print quality relevant parameters, such as Color properties and / or ink transfer properties of the printing plate.
