For example apply Polycarbonate Layer or polrvinyl chloride on file, mix substantially by carbon to Polycarbonate Layer or polrvinyl chloride
The additive that chain is made.If this layer to bombard now with laser pulse, each strand can rupture and discharge carbon.This
Show as the melanism of the layer in the regional extent meeting with laser pulse.Here, the gray level producing generally depends on pulse energy
Amount.
Generally, image progressive or be applied on a file by laser intaglio plate by hurdle.Here, can be on a line or hurdle
There is strong brightness fluctuation between adjacent pixels in inside.For producing the laser of pixel it means that from pixel to picture
Element must greatly change the pulse energy being output.This for example can lead to produce in the case of the optical fiber laser of low cost
The profile of image smear, because laser system will not be followed by with required pulse energy during a line of cutting blocks for printing soon
Speed jump.
Known solution for this problem is for example, or being had using expensive solid laser system or use
The lossy fiber ring laser system of strong band of the quality switches being followed by, they can provide can fast-changing pulse energy
, or slowing down imaging process, thus there is time enough for the arteries and veins required for being correctly adjusted to laser system in amount
Rush on energy.The solution being firstly mentioned means significantly raise for the cost of laser rotogravure device, and is subsequently noted
Section 2 solution then cause the notable prolongation of imaging session time.
Content of the invention
Accordingly, there exist the demand making the personalized method of file blank using image, this demand is in process duration
It is further characterized in that outside few, a kind of device also executing the method using cost laser system, this laser system can be formed
There is slow energy switching.
This purpose is solved by the feature of independent claims respectively.Embodiments of the present invention are in dependent claims
In be given.If there is no clearly contrary expression, then embodiments of the present invention can freely be bonded to each other.
" file " can be high value file or Security document.According to the present invention, file should be understood based on paper
And/or the file based on synthetic material, such as documentary evidence, particularly travelling passport, identity document, visa and driving are held

The memory area of attribute, for preventing the attribute being stored in memory area to be changed in the way of not allowing or not having
Read in the case of promising right needed for this.
On the one hand, the present invention relates to a kind of be used for making the personalized method of file blank using image, for borrowing
Irradiation devices are helped to set up file.Here, file blank has photosensitive layer, this photosensitive layer is configured to adding using electromagnetic irradiation
Carry photosensitive layer when, change photosensitive layer can optical detection at least one parameter.Here, for example can be related to entering using laser
When row loads, the melanism of photosensitive layer or brightness.In the case, the change of parameter, i.e. for example brightness or melanism with logical
Cross the energy that electromagnetic irradiation is added in photosensitive layer proportional.
Electromagnetic irradiation is provided by irradiation devices, and wherein, the intensity of the irradiation being provided by irradiation devices is adjustable
's.Here, the adjustment of irradiation intensity can infinitely or with regularly limited multiple step be carried out.
In the first step in the method, provide monochromatic original image.Original image can be for example that file after a while is held
The portrait of people, or icon or other identification features.In addition to providing and being monochromatic original image, according to the present invention
Can also be by the original image monochromatization of polychrome first in a preposition method and step.Here should be understood that the concept of " monochromatic "
May mean that in this case, monochromatic original image only has a gray value, but or there is the difference of limited color
Brightness value.For example, original image therefore can also be made up of the blue cast of various levels of brightness value.Here, it is permissible to a single picture point
Attach troops to a unit the information content of a bit, this corresponds to 255 different brightness values.
In ensuing method and step, now the brightness value of monochromatic original image is reduced at least two intensity levels
On.In the example of gray-scale picture, this process is known as gray level and reduces.
Here, attaching troops to a unit a unified brightness value to all brightness values within a limited interval.The method step
Result be an original image being reduced, it only also comprises picture point as follows, and the brightness value of these picture points corresponds to this
One of the unified brightness value of a little intensity levels unified brightness value.
In next method and step, the original image that this is reduced is divided into subimage, wherein, in these subimages
Each subimage only has the picture point of same brightness.If for example have selected five intensity levels in method and step above,
Here people also correspondingly obtain five subimages.
Next these single subimages are represented respectively completely imaged on file blank, and its mode is, using electromagnetism
Irradiation carrys out the photosensitive layer of load document blank.Here, attaching troops to a unit one by electromagnetic irradiation photosensitive layer to be added to each intensity level
Energy.Because each subimage only comprises the picture point of same brightness, the i.e. picture point of a single intensity level, therefore in imaging one
During image, the photosensitive layer of file blank merely be attached to this subimage intensity level, energy to be added to load.
The advantage of previously described method can be, need not change irradiation devices during applying a single subimage
Output.Therefore eliminate the waiting time typically requiring, these waiting time are discharged by irradiation devices by adjustment
The energy of electromagnetic irradiation and produce.Meanwhile, in order to change the method according to the invention, it is possible to use only very slowly right
The irradiation devices that the required change of the energy being discharged is reacted, this is because such adjustment only needs once, only exist
Need before starting to be imaged a subimage.Next, whole subimage can utilize irradiation devices once and identical adjustment
It is applied on file blank.
Meanwhile, can be avoided by the method according to the invention, jump to a neighbor from a pixel in intensity level
When, because irradiation devices lead to film coating perfonnance to occur for the excessively slow reaction of the required change of output.Therefore, whole
More visible picture can be produced in the case of using inexpensive irradiation devices by using the method according to the invention on body.
It should be noted here that being reduced it is not necessary to forcibly be related to being present in of an intensity level in the case of a subimage
Whole original image in all picture points.For example, a subimage can also be by a line of the original image being reduced
All picture point compositions of intensity level.In this case, irradiation devices when subimage is imaged repeatedly in turn through a picture
OK, wherein, when once passing through this picture row, only apply a subimage, i.e. an intensity level picture point.
Preferred embodiment, irradiation devices can be lasing light emitter to one kind according to the present invention.Here, lasing light emitter preferably by
It is configured to, this lasing light emitter can release energy limited laser pulse.For example, laser pulse can be that laser energy exists
Between 0.01mJ and 1mJ and pulse width is from the light pulse of such as 3ns to 250ns.Here, such pulse has substantially
The peak power of 10kW to 50kW.The wavelength of the light sending in the case must be adapted to the requirement of photosensitive layer.Generally, in laser
In the case of gravure method, wavelength is proximate to ultrared, such as under 1064nm.In the lasing light emitter using pulsation, applied
Plus each picture point of image then can load photosensitive layer to produce by using the limited laser pulse of energy.
Alternatively or additionally, it is applied on file blank according to which kind of sensitive material and limited it is also possible to substitute energy
A fixed individual pulse, and so that multiple pulses of identical energy is redirect in a picture point.Here, the number of pulse and a single arteries and veins
The product of the energy of punching must be adapted for the energy in the sensitive material to be introduced produce desired intensity level.If for example existed
Determine and during intensity level, have selected 5 grades, then in order to the picture point producing the first intensity level needs a single laser pulse, and the 3rd
In the case of one picture point of intensity level, then need three laser pulses, to obtain a picture point of desired intensity level.Here, swashing
The output of light can keep constant under each pulse, is not dependent on intensity level to be generated.Merely have in different brightness
In the case of level, different number of laser pulse is discharged in a picture point.Yet with sensitive material melanism in certain situation
Under be not be added, be not that each absorbed laser pulse is uniformly increased, thus this point cannot be in all photosensitive materials
Realize in material.
According to a kind of embodiment, lasing light emitter can be optical fiber laser, and it is for example put with the optical fiber being followed by by pulse source
Big device composition.Such system is known as MOPA (MOPA) in the prior art.Using this
When planting optical fiber laser, pump power can be kept during a subimage perfect imaging constant, fiber amplifier is pumped should
Pump power.In order to produce the limited pixel of brightness on the point of the determination in image, then merely have to promote pulse
Source discharges a single laser pulse.This laser pulse is then amplified to the power by keeping constant pump power to be limited
Produce the limited pixel of brightness in level and when striking on photosensitive layer.Thus, permissible using this optical fiber laser
Have the advantage that:Control and can be designed to be very simple for the device executing the method according to the invention, because
During one subimage imaging, the fiber amplifier being used keeps not touching, and merely has to control pulse source and laser irradiation
Orientation on file blank.
According to a kind of embodiment, described at least two intensity levels of the original image being reduced are for each figure to be applied
As individually limiting or making identical for each image to select.Intensity level is made to be adapted to image to be applied, or multiple
The decision keeping constant on image depends on image to be applied.If e.g. such a image, i.e. wherein each picture point
Different brightness values equably may the whole of brightness value spectrally be distributed, then intensity level can be chosen as, to be applied
The uniform amount of the picture point of image be distributed in described intensity level.If the e.g. image of 1000 picture points and selecting
Select four intensity levels, then in this embodiment, the border of these intensity levels can be chosen as so that declining in each intensity level
Enter 250 pixels.It is alternative in this place, intensity level can also be chosen as according to a kind of embodiment, each intensity level comprises phase
Brightness value with number.As above having been carried out, a pixel for example can have 255 different brightness values (1 bit).
If following this embodiment to limit four intensity levels, these intensity levels can be chosen as so that in each intensity level
Including 64 or 63 brightness values.
When a number of intensity level for multiple images should be kept, limit two kinds of aforementioned probabilities of intensity level
Then especially suitable.The process time for producing an image thus can be reduced, because need not for each image individually
Carry out the determination of intensity level.
But can also carry out, the brightness value of the picture point of an image be not be equably distributed to all governable
On brightness value, but the concentration class of the determination brightness value of each picture point for example occurs.In this case, according to the present invention
Planting embodiment it can be beneficial that initially setting up the luminance spectral of image, wherein, luminance spectral being drawn out each brightness value
The picture point being present in original image quantity.Next, clustering method can be applied on this luminance spectral, for
Determine the concentration class in luminance spectral.Next the intensity level using after a while can be made to be adapted to the poly- of this determination lucky of brightness value
Intensity, its mode is for example between two parties and the interval being attached to the brightness value of an intensity level to be corresponded to gathering with regard to a concentration class
The maximum of degree is selecting to be attached to the brightness value of this intensity level.Alternatively, the selection on the border of an intensity level and being attached to
The selection of the brightness value of this intensity level can also be adapted to the shape of picture point aggregation degree in other respects.When concentration class is not deferred to symmetrically
Distribution (Gauss distribution), but consumingly asymmetricly construct when, this point for instance it can be possible that need.
Can separate accurate before being divided into subimage by dithering process and/or tone according to another embodiment
The standby original image being reduced.Thus previously performed being reduced at least two intensity levels can be passed through, make intensity level
Image edge between sub-pictures polishes, thus the improvement of picture quality compared with the original paper based on image.
According to another embodiment, it is applied in the negative film that image is the original image on basis.For this reason, for example can use
Photosensitive layer, this photosensitive layer is not to become relatively deep dark when carrying out irradiation using electromagnetic irradiation, but becomes relatively to become clear.This puts permissible
Have the advantage that:Other changes on image no longer can be carried out after generating the image by the melanism of each picture point.
Thus, a relatively deep dark pixel can for example be added in the case of image positive all the time, but cannot, in negative film feelings
Under condition, make constructed pixel and melanism.Therefore, can be to the antiforgery security of produced file by applying negative film
Improve.
And then previously mentioned embodiment, is designed as according to another embodiment, photosensitive layer positioned at being applied in
Region outside the edge of image is loaded using electromagnetic irradiation, so that fading in these regions.Thus it can be prevented that at this
Extra change can be carried out in a little marginal areas.
According to one embodiment of the present invention, the positive that can also apply image outside being additional to the negative film of image is to literary composition
On part blank.This point can lift the antiforgery security of file further, because can check at any time, negative film is
The shown positive of no adaptation, or whether can determine the difference between two images.
According to another embodiment, file blank has the file body of multilamellar, wherein, layer can be synthetic material and/
Or paper and/or metal and/or polymeric layer.It is designed as in particular according to one embodiment of the present invention, file blank is many

Specific embodiment
Below, element similar each other is identified with identical reference.
Fig. 1 shows the block chart making the personalized device 100 of file blank 102 using image.Device 100 substantially by
Irradiation devices 104 and conveyer device 106 form.Here, irradiation devices 104 comprise lasing light emitter 108, wherein, lasing light emitter 108 is in behaviour
It is connected with laser controller 110 on work.Additionally, irradiation devices 104 also comprise processor device 112 and memory device 114 He
Interface 116.Laser controller 110 also comprises program module 118, and this program module comprises the coding of machine-readable, by reality
Apply this coding and make laser controller 110 manipulation lasing light emitter 108.Lasing light emitter 108 passes through coupling device, such as optical fiber male part
120 are connected with processing head 122.
Here, processing head 122 is configured to, making to be produced by lasing light emitter 108 and conveyed by optical fiber male part 120
Decoupled to the laser irradiation of processing head 122, so that targeted light beam 124 can be output in card blank 102.
Here, the orientation of light beam 124 for example can be carried out by arranging deviation mirror, the orientation of this deviation mirror is by piezoelectricity or electronic
The element activating is controlling.Light steering for example used in processing head 122 can be galvanometer scan galvanometer.Except
It is also possible to make whole processing head 122 elapse in the plane of file blank 102, such as in x-y outside the steering of light beam 124
In the case of recorder (drawing apparatuss) common as.In addition to the passage of processing head 122, it is also possible that file blank
102 are passed with respect to processing head 122.
Here should be understood that processor device 112, memory device 114 and interface 116 need not to be irradiation devices 104
Mandatory part.These elements can also be divided away, as long as they are operationally connected with irradiation devices 104.Example
As processor device 112, memory device 114 and interface 116 can be the parts of single arithmetic system, this arithmetic system line
Cable is connected ground or is wirelessly connected with irradiation devices.
In order to make file blank 102 individualize using device 100 by applying image, first pass through interface 116 and read
Enter original image.Here, original image both can be monochromatic original image or be polychrome, subsequently monochromatic first
The original image changed.Schematically illustrate this original image 202 in fig. 2 a.The original image being read in by interface 116
202 are saved in memory device 114 first.Subsequently, by by processor device 212 implement corresponding program prepare described
Original image 202, so that this original image can be applied in card blank 102.For this reason, limiting monochromatic original first
At least two intensity levels of image 202.This point for example can occur as follows:Storage is accessed by processor device 112
Device 114 simultaneously extracts for intensity level, preservation parameter in this place to be applied, or being analyzed by processor device 112
Stored original image simultaneously executes an other restriction to the intensity level for original image to be applied.This to intensity level
Select to further illustrate subsequently, by means of accompanying drawing 3.
Next, after determining intensity level, all pixels of original image 202 are attached to this according to its brightness value
One of intensity levels, and all pixels in an intensity level a bit are attached to a fixation, new brightness value.With regard to
Gray-scale picture, this process is known as gray level and reduces.The result of this process is a kind of image, only also exists in the images
It is defined the picture point of the brightness value of quantity.Exemplarily, show the image 204 that gray level is reduced in figure 2b.Image 204
It is also subject to image improvement after execution is reduced by the gray level of dithering process.
Here, in the case of illustrating in figure 2b, altogether defining five gray levels.
The image 204 that gray level is reduced is split as in Fig. 2 c by processor 112 in a subsequent method and step
In the subimage that illustrates.Here, subimage 206,208,210 and each in 212 only comprise one and identical respectively
The picture point of intensity level.Thus, such as subimage 206 only comprises the picture point with very bright gray tone, and subimage 208 only wraps
Containing the picture point with middle gray tone, subimage 210 only comprises the picture point with deep dull gray tone, and subimage 212 only comprises
Black picture point.In the case, it is shown without only comprising the subimage of white picture point.
Next consequent subimage 206,208,210 and 212 is stored in memorizer 114.By implementing journey

The picture point of the gray level of subimage 206 just to be applied.If for example lasing light emitter 108 provides the arteries and veins between 0.01mJ and 1mJ
Rush energy, then so that 0.1mJ watt of pulse energy corresponds to bright gray scale.
Next, passing through processing head 122, the position Shangdi that light beam 124 is sequentially applied to pixel to be generated is made to be orientated
In card blank 102, and by manipulating lasing light emitter 108 via optical fiber male part 120 and processing head 122, by pulsed laser output
In the picture point being aimed in card blank 102.Thus, produce on the rum point on photosensitive layer in laser pulse desired
One picture point of gray level.All picture points that this point is in turn directed to subimage to be imaged are performed.When this subimage is complete
When card blank 102 is imaged, just it is loaded into next subimage and is imaged in card blank in a similar manner.Due under
One subimage is the image of different grey-scale, thus here so that lasing light emitter is adapted on its output first to be generated
Pixel gray level to be achieved.If should producing after the subimage for example previously applying and there is deeper dark pixel
Only one subimage, then the output of laser must correspondingly raise.By all subimages 206,208,210 and 212
Transmission, with this approach, the image being reduced 204 can be transferred in card blank 102.
After an image is imaged onto end in card blank 102, the file that conveyer device 106 will produce can be passed through
Remove from processing region.Next a new file blank 102 can be positioned at by irradiation devices 100 by conveyer device 106
