- This surface is hydrophobic in the non-excited state and can be brought into a hydrophilic state by irradiation with ultraviolet light. This switching process can be reversed by heating.
- the imaging is now done by illuminating the entire surface of the plate with ultraviolet light and areas that are supposed to lead to color during printing are covered by a mask or a film. The image areas are then thermally deleted, e.g. B. switched back with a laser beam.
- the hydrophobicity of such a metal oxide surface is based in particular on one with Hydrocarbon contaminated surface in air, as by means of measurements Fourier transform infrared spectroscopy (FTIR) using X-ray photoelectron spectroscopy (XPS), using Atomic Force Microscopy (AFM) or the like can be determined.
- FTIR Fourier transform infrared spectroscopy
- XPS X-ray photoelectron spectroscopy
- AFM Atomic Force Microscopy
- the surface can be removed with the help of UV radiation or Hydrophilize wet chemistry, but it will be back within a few hours of storage uncontrolled hydrophobicity in air. So there is no defined, permanent hydrophobicity as the initial state.
- the object of the present invention is to provide a reusable printing form create, the printing area allows multiple creation and deletion of images.
- the amphiphilic organic The compound can be a surfactant-like compound.
- the amphiphilic organic Compound may be one substituted with an aliphatic or aromatic residue be inorganic or organic acid, which contains at least one element from IV., V. or VI. Main group of the periodic table, especially carbon (C), phosphorus (P), Sulfur (S) or nitrogen (N) has.
- the rest can be an unsubstituted or a substituted aliphatic or a substituted or unsubstituted aromatic.
- the rest can in particular be partially or completely halogenated, in particular fluorinated.
- the rest can in particular have a carbon chain, the number of Carbons is greater than or equal to 12 and less than or equal to 25.
- the amphiphilic organic compound can be a hydroxamic acid or a phosphonic acid.
- the amphiphilic organic compound can be n-heptadecane-hydroxamic acid ⁇ CH3- (CH2) 16-C (O) -NH-OH ⁇ or n-octadecane-phosphonic acid ⁇ CH3- (CH2) 17- P (O) - (OH) 2 ⁇ .
- the metal oxide surface can be a natively oxidized titanium surface, natively oxidized stainless steel surface, for example Hastelloy, natively oxidized aluminum surface, titanate (TiO 2 ) or zirconate (ZnO 2 ).
- the invention is therefore based, inter alia, on the idea of treating technically rough metal oxide surfaces with amphiphilic, surfactant-like organic compounds, in particular applying or coating amphiphilic, surfactant-like organic surfaces on technical rough metal oxide surfaces.
- the reusable printing form can therefore also be referred to in particular as a printing form (in the nano range) that can be recoated.

- the rewritable printing form according to the invention is particularly advantageous in an offset printing process, especially in direct or indirect flat printing, used. It can therefore also be used in particular as a rewritable offset printing form or as a (in the nano range) recoatable offset printing form.
- amphiphilic, surfactant-like organic compounds it is possible to reproducibly defines hydrophobic metal oxide surfaces, in particular Titanium oxide surfaces. That through an amphiphilic organic compound treated printing area can be hydrophobic.
- hydrophilically substituted or terminated amphiphilic, surfactant-like compounds reproducibly defined to produce hydrophilic metal oxide surfaces.
- One by one hydrophilically substituted amphiphilic, surfactant-like compound treated printing area can be hydrophilic.
- amphiphilic, surfactant-like organic compounds n-heptadecane-hydroxamic acid (CH3- (CH2) 16-C (O) -NH-OH) -also their tautomeric form - and / or n-octadecane phosphonic acid (CH3- (CH2) 17-P (O) - (OH) 2).
- the metal oxide surface is in a hydrophobic, color-carrying state brought, which is the initial state for an imaging for an offset printing process can serve.
- the contact angles, measured against water, are hydrophobic Metal oxide surfaces are values from the number set of the interval of real numbers between 80 and 120 degrees.
- the metal oxide surface can then be controlled by Energy supply to be brought into a hydrophilic, ink-carrying state.
- the Contact angles, measured against water, in the hydrophilic state are values from the Number set of the interval of real numbers between 0 and 10 degrees.
- the hub between the both states are therefore sufficiently large for offset printing.
- the invention Printing form is switchable, especially between a hydrophilic and a hydrophobic state. After structuring the rewritable printing form in areas in the hydrophilic and area in the hydrophobic State, an offset printing process can be carried out.
- the reusable printing form according to the invention can be in various Embodiments with different topological and geometric properties be executed.
