- Conditioning 12 is carried out by irradiating the Surface with light of suitable wavelength, intensity and duration of illumination for the subsequent coating step.
- the application 14 of a quantity of substance which contains at least one derivative of n-octadecane-phosphonic acid is carried out as follows:
- the titanium surface is covered with wetted a solution, the above compounds in a suitable concentration, close at the saturation limit, preferably in the concentration of 1 mmol / l.
- the Titanium surface becomes a 1mM ethanolic solution of the derivative of n-octadecane-phosphonic acid (Stearin-phosphonic acid) at room temperature for about 5 Exposed for minutes.
- a cleaning 16 of the treated titanium surface is carried out by rinsing with a organic solvents, an aqueous or alcoholic solution, such as acetone, Ethanol (preferred), isopropanol, ethyl acetate or other suitable organic Solvent, which causes the non-adherent parts of the substance from the n-octadecane-phosphonic acid derivative Solution removed.
- a organic solvents such as acetone, Ethanol (preferred), isopropanol, ethyl acetate or other suitable organic Solvent, which causes the non-adherent parts of the substance from the n-octadecane-phosphonic acid derivative Solution removed.
- a drying 18 of the cleaned, treated titanium surface is carried out with a anhydrous, a so-called dry process gas, here nitrogen, completely reached.
- a check 110 as to whether the color-repellent property of the substrate-contacting element is sufficient or not, can directly on the Surface of the microstructured carrier or indirectly by inspection of the surface of the substrate. If signs of wear of the color-repellent coating can occur or be determined, the Coating process in whole or in part for the affected parts of the surface be repeated. Because of the simple sub-steps of the method according to the invention and its advantageous further developments can be a coating or Recoating can be carried out in a printing material processing machine.
- FIG. 2 is a schematic illustration of a printing press with a Back-pressure cylinder, which is provided with an ink-repellent coating, as advantageous embodiment of a printing material contacting according to the invention Element.
- the printing material 34 is by the printing machine 20 (printing material processing machine) along a Path 36 moves.
- the printing material 34 passes through the blanket cylinder 26 and Back pressure cylinder 28 formed pressure gap.
- Path 36 partially wraps around one first upstream sheet guide cylinder 38, a second downstream Bow guide cylinder 40 and a third downstream bow guide cylinder 42.
- the printing press 20 has a printing unit 44 arranged upstream of the printing unit 22 and the printing unit 46 arranged downstream of the printing unit 46, which is not shown in this illustration are further detailed, but are designed accordingly to the printing unit 22.
- Printing unit 22 the first counter-printing unit of the printing machine 20.
- the upstream printing unit 46 and possibly further upstream printing units, not shown here Printing units of the printing press 20 print on that side (front printing side) of the Printing material 34, which is in contact with the surface of the impression cylinder 28 comes while the printing unit 22 the other side (reverse side) of the printing material 34 printed.
- the printing unit 22 has for the purpose of automatic indirect check whether the ink-repellent property of the impression cylinder 28 is sufficient or not, a detection device 48 which has an optical Examination as to whether the printed image on the printing material 34 is smeared or dirty was made possible. It is immediately clear to the person skilled in the art that, alternatively, a Machine operators perform an indirect check using a visual inspection of the Can make print image.
- the recorded measurement data become one Checking device 50 supplied, in which a setpoint-actual value comparison is made so that a decision as to whether a full or partial one Recoating should be done or not, can be taken as soon as a threshold value of a measure for the deviation from target and actual values is exceeded becomes.
- the printing unit 22 has a coating device 52 with which one complete or partial coating of the microstructured carrier 32 of the Back pressure cylinder 28 can be made without the back pressure cylinder 28 must be removed from the printing unit 22.
- the individual points or positions on the two-dimensional surface of the impression cylinder 28 due to the Rotation of the cylinder around its axis of symmetry and by translation of the Coating device 52 can be reached parallel to the axis of symmetry of the cylinder.
- the coating device 52 is designed such that it covers the individual steps of the can perform method according to the invention or its advantageous developments.
- the coating device 52 can be used by the machine operator if necessary are operated, or the checking device 50 controls the coating device 52 and the impression cylinder 28 at positions where a re-coating appears necessary.
- the method according to the invention for Coating both creating a color-repellent surface Substrate contacting element with reliably reproducible behavior with regard to the substrate management as well as the renewal of a worn one color-repellent surface can be made easily.
- the cycle in the described embodiment of the invention The method according to FIG. 1 can be carried out within 30 minutes.
- the inventive method enables metal oxide surfaces, as they are in common industrial production processes are manufactured, color-resistant.
- the Renewed areas of the paint-repellent surface can be renewed several times made and, particularly advantageously, within a substrate processing Machine.
