The signals relating to the positioning can then be supplied, for example, to one or more drives provided for positioning. Do not always all dryer elements 38 _k , information derived from printed product related characteristics I (G (k)) can be obtained from the dryer elements to be activated 38 _k in the control of the beam or radiation sources 38 _{k, i} , taking into account, for example, for the production in question only the selection G (k) of groups determined thereby 38 _k or dryer elements 38 _k activated activated and / or. is activated or is.

In the second embodiment of the drying agent 38 with dryer elements 38 _k , as printed product-related from beam or radiation sources 38 _{k, i groups} to be formed or formed 38 _k are position and / or size of irradiated section widths and / or distances between the dryer elements 38 _k irradiated section widths variable by, for example, from the totality of the width b38 arranged beam or radiation sources 38 _{k, i} , specific groups depending on the product-related characteristics 38 _k to be activated or activated beam or radiation sources 38 _{k, i} with intervening groups of non-activating or inactive beam or radiation sources 38 _{k, i are} formed. This should also be construed as an embodiment, with smaller groups of radiation or radiation sources 38 _{k, i} corresponding to the printed product related characteristics to several overlapping groups 38 _{k be} summed up.

Additionally or alternatively, the determination can be made on the basis of production-related data P. The production-related data P or information I (P) may be displayed by operators at the operator interface in a manner detailed below 55 provided data, data imported from production planning, or data coming from an inspection system or provided in parallel to the inspection system.

B. computational and / or data processing means 48 to form the groups to be formed for the production in question 38 _k activatable or to be activated beam or radiation sources 38 _{k, i} are used. Thus, information (G (x)) obtained from print product related characteristics can be obtained from subsets of the beam or radiation sources 38 _{k, i} formed and activated groups 38 _k or dryer elements 38 _k in the control of the beam or radiation sources 38 _{k, i} consider, for example, for the production in question only the selection G (x) of radiation or radiation sources determined thereby 38 _{k, i is} activatable.

The selective activation of the dryer elements 38 _k or to groups 38 _k summarized beam or radiation sources 38 _{k, i} itself becomes, for example, in one of the dryer elements 38 _k or beam or radiation sources 38 _{k, i} switching, possibly spatially from the dryer 14 ; 16 ; 36 Included dryer control 49 implemented according to the selection made. The product-relevant selection or the selection and / or formation of the groups 38 _k (G (k); I (G (x)) can also be a basis for the below described case of a wiring which varies in the transport direction (eg indicated in the figures with a direction y) form an overlay in this respect, so that an activating and deactivating, varied in length and / or position, in each case only for the selected and possibly product-related positioned and / or in groups 38 _k of beam or radiation sources to be activated 38 _{k, i} combined dryer elements 38 _k takes place.

For example, in the case of the first embodiment of the desiccant 38 in a first operating situation (eg 9a ) with, for example, a first printing material or printing area width B02; B44 and / or a first transverse profile of pressure gaps 52 a printing area interrupted by non-printable strips 44 a first selection and / or positioning of dryer elements 38 _k activated or activated and in a second, from the first operating situation in the printing material and / or printing area width B02; B44 and / or different second operating situation in the profile (eg 9b ) in the selection and / or positioning to the first operating situation different dryer elements 38 _{k be} activated or activated.

In the case of the second embodiment, in a first operating situation (eg. 10a ) with, for example, a first printing material width B02 and / or a first transversely extending profile of printing gaps 52 a print area interrupted by non-printable columns 44 a first selection of groups 38 _k combined beam or radiation sources 38 _{k, i} activatable or activated and in a second, from the first operating situation in the substrate width B02 and / or the profile deviating second operating situation (eg. 10b ) differing in the selection for the first operating situation beam or radiation sources 38 _{k, i be} activated or activated.

Under a pressure column 52 should be understood here in the transport direction extending pressure strip, which runs on both sides by in the transport direction, not in the printing unit 03 or the relevant printing unit 19 ; 23 printed strips of a strip width are limited, the z. B. Beyond the dimension of individual pixels or color points beyond ready, z. B. has a width of more than 5 mm, in particular more than 10 mm. However, printed strips that are separated by z. B. such non-printed narrow strips of at least 5 mm are interrupted despite their discontinuity in the above sense to larger pressure gaps 52 be summarized or become.

The the dryer 14 ; 16 ; 36 and the controller 37 comprehensive drying device is thus designed and arranged in an advantageous embodiment, only a part of the radiation sources 38 _{k, i in} sections in a plurality, in particular at least four predefinable, transversely to the transport direction to each other approximately, ie by more than 20% from the average distance deviating, equidistant spaced groups 38 _k from radiation sources 38 _{k, i} after a certain sequence simultaneously and / or together on and off. In a preferred development, it is embodied and set up, depending on a cycle Z explained in more detail below, only a part of the radiation sources 38 _{k, i in} sections in a plurality, in particular at least four predefinable, transversely to the transport direction in such equidistant spaced groups 38 _k from radiation sources 38 _{k, i} according to a sequence comprising a plurality and / or at least three equidistantly spaced active phases P _{AN of} a same first phase length, simultaneously and / or jointly turn on and off.

The groups are preferred 38 _k to each other substantially equidistant, ie at most 10% from the average distance deviating, spaced. For example, the distances between the on and off groups differ 38 _k from each other by a maximum of twice the definition of the groups 38 _k transversely to the transport direction considered smallest possible increment, ie the smallest possible in the transverse direction switchable unit, z. B. the width of an above-mentioned more or preferably single-lane LED row.

Of particular advantage is the configuration, ie the positioning and / or selection of the dryer elements to be activated 38 _k or groups 38 _k based on product-related data P or information I (P). In particular, this is done on the basis of information provided by the product-related information I (P), by which a number and position of at least three, preferably at least four in the transverse direction, in particular equidistant, spaced apart on the substrate 02 imprinted or aufzudruckender print elements 56 , in particular the same printed image element 56 , definable and / or fixed. Using this information and taking into account the relative position between the substrate 02 and dryers 14 ; 16 ; 36 at the site of action of the dryer 14 ; 16 ; 36 becomes the positioning of the dryer elements 38 _k or the education groups 38 _k performed or is made accordingly.

The number and distribution of picture elements 56 Information in the transverse direction can basically be obtained in any way and made available in the information I (P). So this could basically from the printed image in its entire width and length image data concerned, z. B. from existing in the prepress data for the entire print image pertaining to printing patterns, be obtained by the evaluation or be. However, this is a great deal of effort and can moreover easily lead to errors due to the high number of each to be determined exposure ranges.

In a particularly advantageous solution, however, these statements to be used for positioning and / or selection are given from data on the number n _X , where n _X ε N ≥ 3, in particular ≥ 4, preferably ≥ 6, and / or the position and / or the size of in the transverse direction next to each other and z.
