At least 2 printing fragments preferably split as follows, and at least 2 printing fragments all comprise a plurality of line segments of at least one fine rule.At least one whole fine rules is only by accurately compatibly printing the line segment of at least 2 printing fragments and producing.Therefore, at least 2 independent whole profile informations that do not comprise at least one fine rule that print in the fragment.

The line segment of printing fragment is the section of the separation of at least one fine rule.This means that always there is vacancy at least 2 sections in the line.

Improve anti-forgery security as follows, by printing technology with the color trend that between at least 2 kinds of tones, alternately changes (

) apply at least one fine rule.Be interpreted as tone or color at this by the observed colour vision of manual observation person.In the ideal case, utilize 2 kinds of printer's inks that have a kind of tone respectively to print described linear pattern.In a preferred embodiment, the printing fragment is all printed the color part (Farbanteil) of at least one line.

In order to obtain smooth color excessively is a kind of rainbow printing, and in one embodiment of the invention, the line segment of the different persons in described at least 2 printing fragments prints in the overlapped mode of part.Form in the overlapping region by increasing color and/or reducing color for colour vision that manual observation person produced.Described colour vision is the blend color that is used to print between 2 kinds of tones of at least 2 printing fragments.

In order to ensure excessive as far as possible glibly, in an embodiment preferred of the present invention, form at least 2 printing fragments of a plurality of line segments that include at least one fine rule as follows, the line thickness of line segment all reduces towards the line segment end.This means, preferably be tapered at its terminal equitant single line segment of line segment with another printing fragment.Thus, the area color of line segment part (

) all reduce towards its end.If described at least 2 the different persons of printing in the fragments different line segments print in partly overlapping mode, the degree that the area portions of line segment is reduced is identical with the degree of the line thickness increase of the line segment of other overlapping printings.

In one embodiment of the invention, at least one utilizes the line segment of the printing fragment of ink jet printing generation to be produced by the only online printing points of walking to make progress overlapping.This means that at least one fine rule forms a line mutually by printing points and produces, they are overlapping along the tangent line of the profile of at least one fine rule.Therefore, at least one fine rule is the optional along moving towards the overlapping printing points that forms a line mutually of single file.

In one embodiment of the invention, the line thickness that utilizes at least one printing fragment that ink jet printing produces changes by the size of printing points.Therefore, towards the line segment end be tapered be since printed dot size reduce cause.Optionally reach extraly, can make of the move towards change of the quantity of printing points, for example reduce, to reduce the color part of unit are along at least one fine rule or line segment.A little size line thickness is tapered extraly or the mild as far as possible color that optionally can be used to be created between 2 different tones is excessive even this is for reducing, and prints overlapped line segment therein.Because with the printing process of adopting printing points for example ink jet printing compare, utilization can realize thinner line thickness usually as the printing process that smooth profile or smooth profile section print at least one fine rule or line segment, so in according to one embodiment of the invention, situation lower line segment in the printing fragment is tapered towards its end, wherein as smooth profile printing line segment, and under the situation of the line segment that produces by the printing process of adopting printing points, the density of printing points reduces towards the end of part section, and color is excessive very uniformly to obtain.Certainly can also change the size of printing points extraly.

Thread pattern normally uses in the substrate that produces based on paper in history.But for the security document of especially only giving or mainly produced by basalis provides thread pattern, basalis is made up of plastic material, in one embodiment of the invention, thread pattern is printed at least one basalis as plastic layer at least in part.Preferably whole thread patterns or at least one fine rule only are printed on the basalis of being made by plastic material.Can make thus apply or embed among the basalis of making by plastic material or on other safety labels obtain safety guarantee by the thread pattern that has printed extraly.
