Definitions
- the invention relates to a precursor plate for the manufacture of an intaglio printing plate. Furthermore, the invention relates to a method of manufacturing the precursor plate and to the use of this precursor plate.
- Intaglio printing plates are frequently used for the production of banknotes and like printed securities.
- a polymer plate or a polymer layer which is supported by a base plate, is engraved.
- a polyimide material containing dispensed carbon black material can be engraved by a laser engraving technique.
- the polymer plate is subsequently used as a precursor material for the manufacture of the intaglio printing plate.
- the polyimide material is usually silvered and used as the master die for the production of the so called (nickel) alto plate. This is performed by processing the engraved polymer plate in an electroforming process, in which the silvered polymer plates are put in a nickel galvanic bath.
- the polymeric precursor material and the nickel alto plate are separated.
- the alto plate is therefore a mirror image basically showing the relief of the engraved precursor plate.
- the surface quality of the nickel alto plate is significantly affected by the quality of the silvered polymeric plate.
- the silvering the polymer precursor plate is carried out by the electroforming chemical process, which consists in the use of chemical solutions containing silver salts and reducing agents.
- the dissolved silver irons are reduced at the surface of the polymeric plate forming the silver layer.
- This chemical process requires the use of various hazardous substances, mainly formaldehyde and ammonia solution.
- the chemical solutions are typically applied on the polymeric surface by a spray technique or by using an oscillating tube. The repeatability of this process is relatively low, since the main operations are carried out manually. This implies that in some cases the process of chemical deposition should be repeated as the result of the presence of defects on the silver layer. In the very worst case, a new polymer plate should be engraved and coated.
- a precursor plate for the manufacture of an intaglio printing plate comprises an engraved surface, which is covered by a coating.
- the coating is formed by physical vapour deposition (PVD) of a coating material.
- the invention provides an alternative process for coating of a precursor plate, based on physical vapour deposition.
- This thin film technique operating under vacuum is able to overcome the drawbacks of the traditional chemical processes.
- the PVD process does not require the use of any hazardous chemicals and it can ensure both, a higher repeatability of the process and a better quality of the coating layer. This advantageously results in a (nickel) alto plate having an enhanced surface quality.
- the coating material comprises Silver (Ag), Gold (Au), Aluminium (Al), Palladium (Pd), Titanium (Ti), Chrome (Cr) and / or any other conductive material.
- the coating comprises any other electrically conductive metal.
- the coating material comprises a composition or an alloy of at least two of the named materials.
- the coating material comprises nitrides and / or carbonitrides of any of the named materials and / or alloys.
- the coating is a multilayer.
- the mentioned materials, alloys and / or compositions can form at least the main component of the coating. This applies to a single layer and to a multilayer coating.
- the coating is a multilayer, at least some of the individual layers can comprise the mentioned materials, alloys and / or compositions, wherein in particular, subsequent or directly adjacent layers can have different compositions. This advantageously applies to all embodiments of the invention.
- other alloying elements can be added to the coating to achieve the desired properties of the material, in particular a desired hardness, wear resistance, etc.
- the coating is a thin layer having a thickness, which can be between 100 nm and 1000 nm.
- the coating of the precursor plate is performed by sputter deposition of the coating material.
- magneton sputtering is applied.
- a working atmosphere during sputter deposition having a pressure which is substantially equal to 0,1 Pa and 1 Pa (0,7*10 -2 mbar to 7*10 -1 mbar) turned out to be advantageous. In particular, this applies to a silver coating.
- the precursor plate is made of a polymer material.
- the polymer material is a polyimide material, for example Kapton.
- Kapton is a polymer, it keeps stable in a wide range of temperatures and can therefore resist the thermal load during coating. Furthermore, Kapton exhibits low degassing properties under vacuum.
- the polymer material comprises laser light absorbing particles or additives, which are dispensed in the polymer material.
- the particles or additives can be manufactured from carbon black material.
- the particles or additives enhance the absorption of laser light in the polymer material and therefore support the laser engraving process.
- This renderers the precursor plate particularly suitable for laser engraving of its surface. This entails that the engraved surface of the precursor plate can be advantageously a laser engraved surface.
- the engraved surface of the precursor plate is pre-treated prior to deposition of the coating.
- This pre-treatment can include a step of surface cleaning and an activation step.
- the precursor plate can be first manually cleaned using isooctane or petrol. Residual dust can be removed using a water jet. Subsequently, oil skimming with calcium carbonate and vinegar can be performed. The surface of the precursor plate is then cleaned using deionized and ultra-deionized water. Finally, the precursor plate is dried in a forced air circulation oven. Subsequent to these steps of cleaning and surface activation, the precursor plate is transferred into the deposition chamber of the PVD unit. The deposition chamber is evacuated using a suitable vacuum system until the residual pressure in the deposition chamber is lower than 10 -2 Pa (10 -4 mbar).
- a method of manufacturing a precursor plate for the manufacture of an intaglio printing plate is provided.
- a coating is deposited on an engraved surface of the precursor plate by physical vapour deposition (PVD) of a coating material.
- PVD physical vapour deposition
- the coating material can comprise Silver (Ag), Gold (Au), Aluminium (Al), Palladium (Pd), Titanium (Ti), Chrome (Cr) and / or any other conductive material.
- the coating comprises any other electrically conductive metal.
- the coating material comprises a composition or an alloy of at least two of the named materials.
- the coating material comprises nitrides and / or carbonitrides of any of the named materials and / or alloys.
- the method comprises the step of depositing anyone of the mentioned materials.
- a coating is deposited, which comprises anyone of the mentioned materials as the main component.
- a thin film having a thickness, which is between 100 nm and 1000 nm, can be deposited. This can be a single layer or a multilayer.
- the coating is advantageously deposited by sputter deposition, in particular by magneton sputter deposition. This can be performed in a working atmosphere having a pressure, which is substantially between 0,7 Pa and 1 Pa (0,7*10 -2 mbar to 7*10 -1 mbar).
- Other deposition technologies can be suitable, for example cathiodic arc deposition.
- the method can include the step of depositing the coating on a precursor plate, which is manufactured from a polymer material.
- the polymer material can be a polyimide material, in particular Kapton.
- the polymer material can comprise laser light absorbing particles or additives, which can be dispensed in the polymer material. Carbon black can be applied for manufacturing the light absorbing particles or additives.
- the method of manufacturing the precursor plate can further include a pre-treatment of at least the engraved surface of the precursor plate.
- This pre-treatment is performed prior to deposition of the coating material, in particular prior to transfer of the precursor plate into the deposition chamber.
- This step of pre-treating can comprise the steps of cleaning and activating at least the engraved surface of the precursor plate.
- the precursor plate can be used for the manufacture of a (nickel) alto plate, which is further designated for manufacturing an intaglio printing plate for the production of banknotes or other printed securities.
- the enhanced quality of the coating of the precursor plate advantageously results in a (nickel) alto plate having a superb surface quality. This renders the alto plate particularly suitable for manufacturing of high precision intaglio printing plates being necessary for the production of banknotes and other printed securities.
