Definitions
- the invention relates to an erasable printing form according to Claim 1 and on a method and a device for deleting and Regenerate the printing form.
- DE 42 35 242 8 is already a suitable one for the wet offset process Printing form known.
- This printing form has at least in its outer layer strong microdipoles, their surface is hydrophobic. After applying of masking material corresponding to an image to be printed Non-image areas hydrophilized by a hydrophilizing agent.
- This Printing forms have the advantage that they can be easily regenerated, d. that is, after a printing process is completed, in a simple manner can be deleted and re-imaged. However, these printing forms have the Disadvantage that their production is complex.
- a forme cylinder which has an anodized or an has a brushed seamless aluminum or chrome surface. He will after Illustrated thermal transfer process.
- There is a on the circumference of the forme cylinder Device is provided which serves to print the printed image after completion of the To remove the printing process. With this device source or Solvent applied to the outer surface of the forme cylinder, or that Print image is heated. The softened or detached print image is then scraped off or peeled off with the help of a film.
- claim 16 is called an apparatus for performing this method.
- FIG single figure shows a printing unit with a Device according to the invention for deleting and regenerating the printing form according to the invention in cross section.
- a printing form In order for a printing form to be easily erased, it must be smooth and non-porous. It must therefore not contain any cavities, at least not on its surface, and must not be rough, so that no mechanical anchors form between the surface and the imaging material, printing ink or dirt that can no longer be removed.
- the surface roughness R a must be ⁇ 1 ⁇ m.
- the printing forms In order for the printing forms to be suitable for the wet offset process, their surface must be either hydrophilic or easily hydrophilizable.
- the printing form is hydrophilized by using a hydrophilizing agent, e.g. B. a plate cleaner, for example sprayed onto them from nozzles.
- the hydrophilicity of the surface must also be recoverable after thermal stress, ie after a thermal fixing step for material applied in the image. So it can at most become reversibly weaker or disappear reversibly.
- Ceramics are suitable as materials for producing such printing forms. They are produced by the sol-gel process, a PVD or a CVD process, in a thermal spray process, for. B. the plasma spraying process, or by a sintering process. The ceramic must then be ground to a mirror finish, ie it may only have a roughness of R a ⁇ 0.3 ⁇ m. If the printing forms produced in one of the processes mentioned are not yet pore-free, they are then sealed.
- Ceramic printing forms contain, for example, aluminum oxide, Aluminum silicate (mullite), zirconium silicate or zirconium oxide. Very cheap it is when the hydrophilicity of a ceramic printing form is not only due to the Hydrophilizing the surface is achieved, but a volume property the ceramic layer.

- the detergent is a solvent or Solvent mixture; it contains no solid components.
- the surface of the printing form is then mechanical grated.
- a cleaning agent containing polishing agent is used for this, for example a plate cleaner, such as that used to clean printing forms generally used.
- the plate cleaner is removed with water, for example, and the printing form is wetted with the Solvent made hydrophobic again for a new one Prepare direct imaging step.
- imaging and fixing becomes the printing form, as known for example from DE 42 35 242 C 1 is hydrophilized again, unless the printing form is already as Material has a hydrophilic surface and it is therefore sufficient if the Non-image areas only due to the dampening solution during the printing process be hydrophilized again.
- the device shown in the figure is used both for deletion and for hydrophilizing and for fixing those described directly above Printing form as well as other printing forms, such as those according to the DE 41 23 959 C 1 or DE 36 33 758 A 1 known are.
- the fixing step is that the illustrated printing form of a dryer 7 to a surface temperature between 170 ° C and 210 ° C is heated.
- the printing form is either inductive or heated an infrared heater. With other fixation methods UV rays or electron beams are used. It is also possible that Hardening printing forms with suitable chemicals, for example only through moisture.
