It is difficult to forge a check

The invention relates to a check that is difficult to forge made of water-free paper, suitable for electronic plain text readers, on which the check background and text are printed and which one special, of the printed check background with text that has not been used for reading only automatic check processing the code line for electronic plain text readers contains »

Hitherto been hampered spoofable checks are _r produced in that a watermark is imprinted in the preparation of the check the paper in the same a characteristic oaks in shape, through which the genuine check differs from a counterfeit, not such a watermarked with · Check c This watermark, which is composed of imiüerwiederkehrenden same characters, the entire area decreases in a continuous Polge of the paper web a _p so that there is no greater path section within which is not a part of the watermark is visible "the resulting paper web is then either into individual corresponding to the check format sheet cut up and the check background printed on the same with text; alternatively ^ pierbahn in Rotativverfahren the ground and text .s concerned manufactured checks printed in imiierwiederkehrender succession and then the paper web into individual _f the check format appropriate and ready-printed sheets are cut to the ablaufer from a supply roll "·".

This type of production has the disadvantage that it cannot be used for the production of checks which have a special reading section which is not occupied by the printed check base with 2ext and which only contains the code line applied for the automatic processing of checks würd3n namely prepared by Deia above-described "method ;, not be mechanically recyclable, as the material introduced in the ichockpa = pierherstellung watermark also But the area of the code line extends, which thus m neb the printed encode numbers further calibrate by the enemy are related Light -Dark contrast points. These additional contrast points are sure to cause incorrect readings of the electronic plain text readers with which the automatic check processing is carried out.

Verwenlen to eliminate Jieses drawback, it is further known, watermark-free for checks paper au, on which the check background and text et aufgedrv and applied the encoding ropes in a special still unprinted Leseabschnixt of Schicks ° In such checks is indeed a false reading by the electronic Plain writing lasers are essentially excluded, but these checks have the disadvantage that they are easy to forge because they do not contain a watermark or a watermark similar to the 2s mark ο

} It is »possible to emboss watermarks in the check paper production in such a way that they follow one another with a gap corresponding to each section, in that in the flat sieve and cylinder sieve machines with which the water marks are embossed into the paper pulp, the embossing dies j at appropriate intervals lengthways of the flat sieves j bsw »are distributed along the circumference of the cylinder sieve» We :: but here (the check format changed? the sieves used up to now have to be replaced by new sieves with newly spaced embossing stamps, which means that the mechanical um · · Posting to a different check format made very expensive and uneconomical

Another disadvantage is that the size of the customer's screen must be a whole-number multiple of the "relevant check format" so that the stamps can be distributed along the entire circumference of the cylinder. , otherwise there is a case that the Eundsiebumfang can not be fully utilized for the Wasserzeicheneinprägung, but in this case a part of the circular screen "scope must remain without die ₅ leading to! sequence _s is that also a corresponding portion in the pulp not A watermark is provided, which is thrown away when the paper web is later cut into individual sections corresponding to the check format); this has to result in a further increase in the cost of check production.

Another disadvantage of using a paper web with spaced-apart watermarks for checks is that it is troublesome in the PaHe, in which the check background and check text are applied by rotary printing and the paper web unwinding from a feed roller past the printing rollers to apply the check background with text precisely to the paper area occupied by the watermark, =

C Ds ^ invention is based on the object using a water-free paper is difficult to forge Create a check of the type described at the beginning, which one with a much more economical process and with can be produced at significantly lower costs compared to the previously known production methods of this type can "

"that in the paper outside of the reading section in the area of the check underside reason one or more at. Check printing with applied Marks from the eleventh penetrated into daa paper, essentially colorless ,; drying Plüssiglceit provided which is so constituted, that on the soaked, the Porm of the place or marks corresponding of the paper is the same with the dried liquid against the Light more transparent than on, the other non-elongated sections is·"

The measures according to the invention have the advantage that on the relatively expensive known manufacturing processes for Production of paper webs with spaces free from water cores separate watermarks can be dispensed with and still an effective protection against check forgery. is obtained, since this is due to the soaked parts of the check paper Marks formed such as a watermark can have a special, difficult to imitate shape and are watermark-like is included in the paper. In addition, siph leaves this indicator on without any particular difficulty bring up the plan of the check background, since this According to the invention, the relevant check background and text are applied in the course of the printing process.

The application of the label from the essentially colorless, drying liquid on at least one side of the Checks can be used with all common printing methods such as Perform offset printing, direct and indirect letterpress or halftone gravure «

The places corresponding to the shape of the mark (s) in the paper are preferably with a drying and additionally with a l'rooken material (Silckativ) mixed vegetable soaked in oil »By adding this dry substance, by the fact that the oil in question is siccativized, a thickening of the oie occurs, which makes it printable, see above that the oil can be printed on the respective Scheok paper in the form of the desired identification number,

Linseed oil, nut oil, Chinese wood oil, perilla oil, poppy seed oil, lianquette nut oil, gum oil, i; ianih _o t oil, sunflower oil, hemp oil, Japanese wood oil, flat candle seed oil, plukenetia oil or these oils can be used. The use of linseed oil is particularly advantageous here, since this oil is relatively viscous and therefore very suitable for printing. In addition, linseed oil is relatively cheap to get in stores »

The marking consisting of the drying liquid can be applied to the watermark-free paper at any time. However, if the application is carried out of this liquid to the paper as a final process step, this has 3en advantage that it can be checked at the same Aufbrijagvorgang that the flag fits exactly to the area covered by the Rcheckuntergrund paper surface.

A check designed according to the invention also brings it with it that with 'rotary printing the check background with Text can be printed on the paper web in either portrait or landscape format, as this is from the drying Liquid existing labels can be applied in portrait or landscape format. Because precisely because the imprint this indicator according to the invention in the course of the printing process of the check in question takes place, it is conveniently possible to apply the mark to be applied to the relevant printing roller set in portrait or landscape format »This alternative setting option is particularly important if the check format is to be changed. Indeed, it can easily be possible that the extent of the pressure rollers used, which is an integer multiple of the length of the relevant check in portrait format, for example, is just big enough that if the check format is changed, the The horizontal format length of this other type of check also fits as an integer multiple on the circumference of these printing rollers, whereby it is not necessary to replace these rollers against new pressure rollers with a correspondingly different diameter exchange in order to be able to print out the other check format. In contrast, it is in the case where how

described above "already in the production of Scheekpapier Water bank that is with the width of the reading absenteeism successive corresponding gaps, are embossed into the paper web, then during the printing process no longer possible to print out either in portrait or landscape format, as the position of the format is determined by the position of the predetermined watermark located in the paper web is.
