- FIG. 2 shows the area on a banknote printed with intaglio intaglio printing.
- FIG. 1 shows the process sequences of two known methods and an embodiment of a method according to the invention for producing a printing plate for intaglio intaglio printing.
- the numbers in the circles indicate those for each
- a graphic 1 is assumed, which is in particular in electronic form as
- Data file can be present.
- a film is first exposed in a method step 6, which essentially has the size of a base plate to be produced, on which the graphic 1 is arranged several times.
- Method step 15 generates a working die by means of galvanic molding, in which flaws are retouched in a method step 16.
- Method step 16 generates a working die by means of galvanic molding, in which flaws are retouched in a method step 16.
- a pressure plate is produced from the work die by means of galvanic molding, which is retouched in a method step 18 and chrome-plated in a method step 4, whereby a finished pressure plate 5 is obtained. This procedure takes about 15 days.
- a polymer image 8 In order to obtain the working die, on which the graphic 1 is contained several times, in the intermediate steps 8 to 15 a polymer image 8, electroplating 9, subsequent retouching 10 and renewed electroplating 11 become a single image
- An embossing plate is produced, with which after individual retouching 12, a plurality of individual images are embossed in a method step 13, which are combined in method step 14 to form a full image, from which the working die is electroplated in method step 15.
- the further process for producing the finished printing plate corresponds to the process described above. It takes about 48 days to produce a finished printing plate.
- printing plates are usually mounted on a printing roller for intaglio gravure printing. It takes about 9 more days to produce two more printing plates from the work die.
- depressions and / or lines are introduced into a base body made of a brass alloy with a laser.
- a base body made of a composite material with an outer layer made of a brass alloy can also be provided.
- Brass refers to copper-zinc alloys that have at least 50% Cu. In addition to copper and zinc, brass can also contain up to 3% lead. If other elements besides lead are added, one speaks of special brasses. Brass alloys in the sense of the invention can be both brasses and special brasses.
- the information in a graphics file is converted directly into control commands for the laser by means of a computer-controlled laser system.
- the printing plate can be produced immediately after the graphics file has been created, essentially no further intermediate steps being required.
- the depth of the depressions and / or lines is also specified. This can be done for each well and / or line individually or together for a group of wells and / or lines.
- the specifications of the individual depths are independent of each other. Different depths can be easily achieved in the method according to the invention by regulating the power of the laser beam or by repeated lasering.
- the depth of the depressions and / or lines can be predetermined regardless of their width in the method according to the invention. It can also be provided that the depth of an individual line changes over the course thereof, it being possible for the width of this line to remain the same.
- a solid-state basic mode laser preferably a diode-pumped, Nd: Y AG laser, can be used as the laser.
- the laser beam penetrates the material surface in a cone shape. Melting processes occur in the edge area of the focused beam, which cause part of the material to solidify into unwanted ejections and splashes.
- the type and size of the edge ejection depend on the material, the pulse power and the engraving depth.
- the laser can be used to engrave metals, ceramics and some plastics, whereby the power density of the laser beam is so high that the material evaporates during processing - 'partially evaporates within a few nanoseconds, the material creates a colorless recess - the engraving.
- the interaction of the melted base material with the atmospheric oxygen often forms oxides, which due to their color make the engraving stand out more clearly.
- the depressions and or lines can be introduced particularly quickly and easily, as a result of which the required production time can be kept short. It can be provided that an engraving head connected to the laser and / or the base plate is fastened with a slide element that can be moved in at least two different directions that are essentially parallel to the flat plate, so that an engraving head movable in the xy direction and or one in the xy direction Direction movable base plate is formed.
- a movement sequence can be determined for a predefinable template, in particular the graphic file mentioned above, which ensures the shortest possible production time of the printing plate. It is not necessary to completely paint over areas into which lines and / or depressions cannot be made.
- the engraving head can have fixed optics or a galvanically deflected mirror system (galvo system). A particularly good quality of the laser and a short manufacturing time can be achieved by a combination of these two optics.
- a plurality of galvanically deflected mirror systems can be provided, which are optimized for different line widths and depth ranges.
- vector-based graphics 1 can also be processed with the engraving head and thus only those areas can be specifically processed which contain a printed image.
- FIG. 2 shows a bank note 20 which has an area 21 with intaglio intaglio printing. It is common for region 21 not to extend over the entire banknote 20.
- the base body can also be curved, in particular in the form of a cylinder, cylinder section or the like.
- the reliability and quality of the printing plate when the depressions and / or lines are introduced can be monitored in a simple manner by means of a control device by detecting the emission of laser pulses. If a laser pulse is not emitted, the control device can initiate the command to re-emit a laser pulse, thereby reducing the risk of defects.
- the accuracy of the depressions and / or lines can be improved if the melting burrs which arise when the depressions and / or lines are introduced into the base body are removed.
- These melting ridges consist essentially of oxidized material of the base body, in particular of copper oxide or zinc oxide.
- a chemical aftertreatment which can in particular comprise an acid bath, an electrolytic bath or the like, appears to be particularly suitable for removing the melt burrs. It can be ensured that the copper oxide or zinc oxide, but not the brass alloy of the base body, is removed by the chemical aftertreatment.
- the chemical aftertreatment can be carried out in particular by immersing the base body in an acid bath or the like, which comprises phosphoric acid, acetic acid, nitric acid, arsenic acid or the like, or a combination of these acids.
- An acid bath comprising acetic acid, phosphoric acid and nitric acid appears to be particularly favorable, the acid bath in particular can have about 40% by volume of acetic acid, 50% by volume of phosphoric acid and 10% by volume of nitric acid.
- Removal of the melt burrs can further be provided for retouching and / or checking the printing plate in order to be able to identify and correct any imperfections that may be present.
- the service life of the printing plate can be further improved if the base body is chrome-plated in a further process step.
- a printing plate for intaglio intaglio printing which has a base body made of a brass alloy and / or
- Base body can be introduced.
- melt burrs formed by the laser can be removed quickly and easily from a brass alloy by post-treatment.
- Brass alloy has a Vickers hardness greater than 140.
