If this layer is now bombarded with a laser pulse, individual molecular chains can break up and carbon can be released. This manifests itself in a blackening of the layer in the region of the region hit by the laser pulse. In general, the generated gray level depends on the pulse energy.
  • graphics are applied to a document line by line or column by column by laser engraving. It can come within a row or column to strong fluctuations in brightness between adjacent pixels. For a laser generating the pixels, this means that the emitted pulse energy has to be varied greatly from pixel to pixel. For example, this can lead to blurring of the contours of the graphics produced in low-cost fiber lasers, since the laser system can not follow the rapid jumps in the required pulse energy during the engraving of a line.
  • Known solutions to this problem include, for example, either the use of expensive solid-state laser systems or highly lossy fiber laser systems with downstream Q-switches, which can provide fast-variable pulse energy, or slowing down the imaging process so that there is sufficient time to properly tune the laser system to the required pulse energy is.

  • the invention relates to a method for personalizing a document blank with a graphic for producing a document by means of an irradiation device.
  • the document blank has a photosensitive layer, which is designed such that upon exposure of the photosensitive layer with electromagnetic radiation at least one optically detectable parameter of the photosensitive layer changes.
  • This may be, for example, a blackening or whitening of the photosensitive layer upon exposure to laser light.
  • the change in the parameter that is, for example, the brightening or blackening, scales with the energy introduced into the photosensitive layer by the electromagnetic radiation.
  • the electromagnetic radiation is provided by an irradiation device, wherein the intensity of the radiation provided by the irradiation device is adjustable.
  • the intensity of the irradiation can be adjusted step-by-step or in defined steps.

  • the term "monochrome" in this case can mean that the monochrome output graphic has only gray values or different brightness values of a defined color Pixel can be assigned an information content of one byte, which corresponds to 255 different brightness values
  • the brightness values of the monochrome output graphics are now reduced to at least two brightness levels. All brightness values within a defined interval are assigned a uniform brightness value. The result of this method step is a reduced output graphic, which contains only pixels whose brightness value corresponds to one of the uniform brightness values of the brightness levels.
  • This reduced output graphic is subdivided into sub-graphics in a next method step, wherein each of the sub-graphics has only pixels of the same brightness. If, for example, five levels of brightness have been selected in the previous method step, then five subgraphs are also obtained accordingly.
  • each brightness level is assigned an energy to be introduced by the electromagnetic radiation into the photosensitive layer. Since each sub-graphic contains only pixels of the same brightness, that is to say pixels of a single brightness level, when imaging a sub-graphic, the photosensitive layer of the document blank is only exposed to the energy to be applied associated with the brightness level of the sub-graphic.
  • the method described above could have the advantage that during the application of a single partial graphic, the output power of the irradiation device does not have to be changed. This eliminates the usually necessary waiting times, which result from the conversion of the energy of the electromagnetic radiation emitted by the irradiation device.
  • irradiation devices can be used to implement the method according to the invention, which react only very slowly to a necessary change in the emitted energy, since such a conversion is only once, namely only necessary before the start of the imaging of a partial graphic. Subsequently, the entire partial graphic can be applied to the document blank with one and the same setting of the irradiation device.

  • the product must be adapted from the number of pulses and the energy of a single pulse of the energy to be introduced into the photosensitive material for the generation of the desired brightness level.
  • a single laser pulse would be necessary to generate a pixel of the first brightness level, while three pixels would be necessary to obtain a pixel of the desired brightness level for a pixel of the third brightness level.
  • the output power of the laser can remain constant for each pulse, regardless of the brightness level to be generated. It would be necessary to deliver different numbers of laser pulses to one pixel only at different brightness levels.

  • the pulse source In order to generate a pixel of defined brightness at a certain point within a graphic, it is then only necessary to cause the pulse source to emit a single laser pulse. This is then amplified to the power level defined by the pumping power held constant and generates a pixel of defined brightness when hitting the photosensitive layer.
  • the use of such a fiber laser could have the advantage that the control of a device for carrying out the method according to the invention can be made very simple, since during the imaging of a partial graphic of the fiber amplifier used remains untouched and only the pulse source and the alignment of the laser radiation must be controlled on the document blank.

  • the decision whether to adjust the brightness levels to the graphics to be applied, or to keep constant over a large number of graphics depends on the graphics to be applied. If, for example, a graphic is used in which the different brightness values of the individual pixels are distributed uniformly over the entire spectrum of possible brightness values, the brightness levels can be selected such that the number of pixels of the applied graphics is distributed uniformly over the brightness level. If, for example, the graphics are 1000 pixels and four levels of brightness have been selected, then in this embodiment the limits of the brightness levels should be selected such that 250 pixels fall in each brightness level.
  • the brightness levels may also be selected such that each brightness level includes the same number of brightness values. For example, as previously stated, a pixel may assume 255 different brightness values (1 byte). If one were to define four brightness levels for this embodiment, they would have to be selected such that 64 brightness values are contained within each brightness level, or 63 brightness values.
  • the two abovementioned possibilities of defining the brightness levels would be particularly suitable if a number of brightness levels is to be maintained for a plurality of graphics.

  • the brightness levels used later can be adapted to brightness values at precisely these ascertained accumulations, for example by centering the interval of the brightness values associated with a brightness level with an accumulation and the brightness value associated with the brightness level corresponding to the maximum of the brightness level Accumulation is chosen.
  • the choice of the limits of a brightness level as well as the choice of the brightness value associated with the brightness level can also be adapted otherwise to the form of the clustering of the pixels. This could be necessary, for example, if accumulations do not follow a symmetrical distribution (Gaussian distribution) but are strongly asymmetrical.
  • the reduced output graphic may be rendered prior to subdividing into sub-graphics by dithering and / or posterization.
  • edges of the graphic that have occurred between the sub-images of the brightness levels that have occurred due to the previously performed reduction to the at least two brightness levels can be smoothed so that an improvement in the image quality is achieved compared to the original underlying the graphic.
