DETAILED DESCRIPTION OF THE EMBODIMENTS

[0060] FIG. 1a shows a data carrier 100 in the form of a passport booklet in ID-3 passport format from outside, and FIG. 1b shows the data page 134 located inside the passport booklet of the data carrier 100 in the variant of the passport booklet from FIG. 1a. In particular, a photo image box 110 and a data field 120 are illustrated as well as an information area 130.

[0061] FIG. 2a illustrates schematically from the side a device 200 for imprinting the data carrier 100 in the variant as a passport booklet. This device 200 has a printer inlet 202, which in this configuration is adapted and dimensioned to receive the data carrier 100 in the folded-open state in a carriage 204 positioned in such a way that the area of the data carrier 100 to be imprinted, thus the photo image box 110, the data field 120 and the information area 130, for example, is exposed. In the present variant, the adjacent page of the passport booklet next to the data page is also exposed in addition. The fold or spine 104 of the passport booklet lies in the direction of transport of the passport booklet through the device 200. Furthermore, the (printer) device 200 has a printing head 206, here in the variant of an inkjet printing head, which comprises containers or tanks 205 with two or more inks. In the present example there are five containers for the inks Cyan, Magenta, Yellow and an ink black component Key (first inks), as well as an ultraviolet-light-active ink (second ink). These inks are all ultraviolet-light-curable inks in the variant shown here.

[0062] The printing head 206 is taken up on a rail 208 to move the printing head 206 using a drive, not illustrated further, transversely to the conveying direction F of the carriage 204 along the arrow Q (see FIG. 2b) from one side of the passport booklet to the other. The printer jets of the printing head 206 are controlled via a controller, not illustrated further, such that the first inks and the second ink can be printed in a controlled manner onto the exposed area of the data carrier 100 to be imprinted, in order to imprint personalisation data of the bearer (for example, date of birth, place of birth, photo of the bearer, biometric data of the bearer, along with place and date of issue and period of validity of the passport booklet). The first inks, the second ink and the third ink can be imprinted on the data page 134 and/or on the adjacent page 136, of paper.

[0063] To convey the data carrier 100 in the carriage 204 from the printer inlet 202 into the region of the device 100 where the printing head 206 is able to imprint the area of the data carrier 100 to be imprinted, the device 100 has a conveyor device 220 in the form of several pairs of conveyor rollers 220a . . . 220h, some of which can be driven at the instigation of the controller. The spacing of the individual rollers of each of the pairs of conveyor rollers 220a . . . 220h is determined such that the carriage 204 with the data carrier 100 located therein is taken up between them and is movable back and forth along the conveying direction F. The data carrier 100 is thus to be moved in the carriage 204 relative to it and the printing head 206. The printing head 206 is able to act upon the area of the data carrier 100 to be imprinted. Alternatively, the carriage 204 can also be arranged on at least one linear guide, wherein the conveyor device 220 can have a toothed belt connected to a drive, which belt can be led around at least one drive pulley and a deflection pulley.

[0064] Provided downstream of the printing head 206 in the device 100 is a curing station 230 spatially remote from the printing head 206. It is also provided in one variant to connect the curing station 230 directly to the printing head 206.

[0065] The control device 300 is adapted and programmed to cause all or some of the rollers of the pairs of conveyor rollers 220a . . . 220h of the conveyor device 220 to move the data carrier 100 in the carriage 204 relative to the printing head 206. The printing head 206 is thus able to imprint the area of the data carrier to be imprinted. The control device 300 is also adapted and programmed to cause the printing head 206 to imprint the area of the data carrier 100 to be imprinted with personal data using at least a first of the inks.

[0066] The control device 300 is also adapted and programmed, once the print process of the personal data using the first inks Cyan, Magenta, Yellow and Key is complete, to cause the conveyor device 220 to move the data carrier 100 relative to the curing station 230 in a first direction (to the right in FIG. 2a, 2b), so that the curing station 230 is able to act upon the area of the data carrier 100 to be imprinted.

[0067] The curing station 230 comprises a field with UV light sources 232, as UV LEDs in the variant shown. The control device 300 is also adapted and programmed, when the data carrier is located in the area of the curing station 230, to activate the latter and to cause at least partial surface drying of the first ink(s) in the area of the data carrier 100 to be imprinted. This process of surface drying the first ink lasts in the range of a few milliseconds to milliseconds depending on the ink and lacquer.

[0068] The control device 300 is also adapted and programmed, following the drying, to cause the conveyor device 220 to move the data carrier 100 relative to the printing head 206 in a second direction opposite to the first (to the left in FIG. 2a, 2b), so that the printing head 206 is able to imprint the area of the data carrier 100 to be imprinted.

[0069] The control device 300 is also adapted and programmed, as soon as the data carrier 100 is again located in the access range of the printing head 206, to cause the printing head 206 to imprint the area of the data carrier 100 to be imprinted using at least a second of the inks, here the ultraviolet-light-active ink.

[0070] A second print process then takes place with the ultraviolet-light-active ink. The imprint (text, photo, graphics) using the second ink mostly differs from the imprint using at least a first of the inks.

[0071] The control device 300 is also adapted and programmed, as soon as the imprinting process using the ultraviolet-light-active ink has finished, to cause the conveyor device 220 to remove the data carrier 100 in the carriage 204 from the device 100. If the conveyor device 220 removes the data carrier 100 from the printer in the first direction, the data carrier 100 also passes the curing station 230. In this case at least partial surface drying of the second ink in the area of the data carrier 100 to be imprinted can also take place.

[0072] The carriage 204 is used to receive the data carrier 100 before or during entering of the data carrier 100 into the printer 100 and to fix it in its position and orientation. A fixing device is used for this in the form of several blank holders 262, which are provided for the targeted fixing and release of the data carrier 100 in the carriage 204. More precisely, the blank holders 262 are arranged on the inner edge of the carriage 204 and determine the position and angular orientation of the data carrier 100 when the carriage 204 is brought under the printing head 206.

[0073] Furthermore, the device 100 is provided with a sensor array 280 of one or more optical cameras, which are adapted and dimensioned to detect before imprinting, thus during equipping and introduction of the carriage 204 with the data carrier 100 and during imprinting of the area of the data carrier 100 to be imprinted, the position of the data carrier 100 relative to the printing head 206 and to signal this to the control device 300. The precise arrangement of the sensor array 280 relative to the other components of the device results from the structural circumstances and is to be determined accordingly.

[0074] Based on the sensor signals from the sensor array 280, the control device 300 is further adapted and programmed to cause the conveyor device 220 to adjust the relative position between the printing head 205 and the data carrier 100 depending on the position of the data carrier 100 in the printer. The speed and the angle of rotation of individual rollers of the conveyor roller pairs 220a . . . 220h are adjusted if necessary for this. Alternatively to this, the positional information, i.e. an x- and y-value of e.g. the edge of the passport or of a reference point on the data page 134, is obtained from an image recording of the data carrier 100 and its data page 134 in another variant. It is recognised from this by image processing whether/how far the passport was incorrectly clamped. For a correctly positioned print the print layout is then rotated and/or moved per image processing.

[0075] The blank holders 262 on the inner edge of the carriage 204 are also activated or deactivated targetedly to fix the data carrier 100 in the desired orientation and position in the carriage 204 when the data carrier 100 is introduced into the carriage 204 from outside the device 100.

[0076] The sensor array 280 in the variant shown is an imaging sensor. It is also possible, however, to use a mechanical, capacitive or other sensor. The sensor array 280 is also adapted and dimensioned in one variant to detect the quality/intensity/positional accuracy of the print image with the first and/or the second of the inks on the area of the data carrier 100 to be imprinted following and/or during the imprinting of the area of the data carrier 100 to be imprinted, and to signal a measure of the quality/intensity/positional accuracy of the print to the control device 300.

[0077] In the device 100, the control device 300 is further adapted and programmed, before removal of the data carrier 100 from the printer (device) 100, to cause the conveyor device 220 to move the data carrier 100 relative to the printing head 206 in a second direction opposite to the first, so that the printing head 206 is able to imprint an area of the data carrier 100 to be imprinted.

[0078] In the device 100, the control device 300 is further adapted and programmed to cause the printing head 205 to imprint the area of the data carrier 100 to be imprinted using at least a third of the inks. In this case at least one of the third inks is suitable and intended to seal the previously applied first and second inks at least in sections on the area of the data carrier 100 to be imprinted. The third ink can be a UV-light-curable lacquer.

[0079] In the device 100, the control device 300 is further adapted and programmed to cause the conveyor device 220 to move the data carrier 100 relative to the curing station 230 in the first direction after the data carrier 100 has been imprinted with the at least one, third ink. The curing station 230 is thus able to act upon the area of the data carrier 100 to be imprinted.

[0080] In the device 100, the control device 300 is further adapted and programmed to subsequently cause the curing station 230 to at least partially surface dry the at least one, third ink in the area of the data carrier 100 to be imprinted in the curing station 230.

[0081] In the device 100, the control device 300 is further adapted and programmed to cause the fixing device 260 to release the fixing of the data carrier 100 in the carriage 204 before or after the last, at least partial surface drying. In the variant illustrated here, the fixing and release of the fixing of the data carrier 100 in the carriage 204 is coupled temporally and spatially to the movement of the carriage 204 relative to the printer by the conveyor device 220.

[0082] In the device 100, the control device 300 is further adapted and programmed to cause the conveyor device 220 to bring about appropriate dwell times of the data carrier 100 in the curing station 230 depending on the respective one of the inks previously printed onto the data carrier 100 for the respective at least partial surface drying of the inks. For example, the controller 300 can be adapted such that the imprinting of the third ink onto the data carrier 100 or the imprinting of an ink from a previously defined tank effects a longer dwell time of the data carrier 100 in the curing station 230.

[0083] Finally, in the device 100, the control device 300 is further adapted and programmed to hold the printing head 205 stationary or to reposition it when imprinting the area of the data carrier 100 to be imprinted and a print field located adjacent to the area to be imprinted, here on the adjacent page 136, with one of the inks.
