This point can, for example - based on the operating direction of rotation - up to 5 ° before or after the nip 06; 07 may be provided with the counter-pressure and / or transport cylinder 21. The thus employed doctor blade 34 accumulates a bead of ink, which she rolls in front of her and through the permeable areas of the screen printing stencil 31; 32 pushes outwards.

As a result, premature setting of the blade 34 lifted off, for example, when the nipple passes through the open region of the opening 28 is made possible. The cover element 29 may, for example, overlap slightly with the undisturbed cylinder jacket peripheral section and, in this case, reduces the length of the maximum usable peripheral section U _D for printing. This geometric shortening is due to the premature Hiring z. B. more than offset. Due to the premature setting can - in relation to the unrolling during operation - upstream pressure range beginning ideally immediately, but possibly additionally connect over a slight safety distance to the cover 29.

B. three times, such a holding device 24 and a respective intermediate cylindrical barrel-shaped peripheral portion (see, eg. Fig. 2a ). In the case of a web-processing version of the printing press, such holding devices can be dispensed with (see, for example, US Pat. Fig. 2b ). Colloquially includes the n-times large cylinder 21 n each without interruption usable for printing peripheral portions U _D.

In an advantageous embodiment for the case of the multi-dimensional arrangement of radiation sources 38 _{k, i} , the simultaneous and / or joint switching is related to the passage of the printing material 02 for the relevant line. In this case, the "simultaneous and / or joint" switching of the radiation sources 38 _{k, i} encompassed by the participating groups takes place in such a way that the radiation sources 38 _{k, i} to be switched are switched on and off simultaneously and / or jointly correlated to the printing material feed.

Thus, information (G (x)) obtained from print product-related characteristics can be transmitted via the groups 38 _k or dryer elements 38 _k formed and to be activated from sub-quantities of the beam or radiation sources 38 _{k, i} during the control of the beam or radiation sources 38 _{k, i} consider, for example, for the production in question only the thus determined selection G (x) of beam or radiation sources 38 _{k, i is} activatable. The selective activation of the dryer elements 38 _k or the beam or radiation sources 38 _{k, i combined} themselves into groups 38 _k , for example, is switched off in a dryer or 38 _k or beam or radiation sources 38 _{k, i} , possibly spatially from the dryer 14 ; 16; 36 included dryer controller 49 implemented according to the selection made.

For example, in the case of the first embodiment of the drying means 38 in a first operating situation (eg. Fig. 9a ) with, for example, a first printing material or printing area width B02; B44 and / or a first transversely extending profile of printing gaps 52 of a printing area 44 interrupted by non-printable strips, a first selection and / or positioning of dryer elements 38 _k can be activated or activated and in a second, from the first operating situation in the printing substrate and / or pressure range width B02; B44 and / or different second operating situation in the profile (eg Fig. 9b ) can be activated or activated in the selection and / or positioning to the first operating situation different dryer elements 38 _k .

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

The dryer 14; 16; 36 and the control device 37 comprehensive drying device is thus designed and arranged in an advantageous embodiment, only a portion of the radiation sources 38 _{k, i in} sections in several, in particular at least four predefinable, transversely to the transport direction to each other approximately, ie by more than 20% of the average distance different, equidistant spaced groups 38 _k of radiation sources 38 _{k, i} after a certain sequence simultaneously and / or jointly on and off. In a preferred development, it is embodied and set up, depending on a cycle Z detailed below, only a portion of the radiation sources 38 _{k, i in} sections in a plurality, in particular at least four predefinable, transversely to the transport direction equidistant from each other such groups 38 _k of 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 38 _k are preferably substantially equidistant from each other, ie at a distance of at most 10% from the average distance. For example, the distances between the groups 38 _{k to} be switched on and off differ from each other by a maximum of twice the step size considered in the definition of the groups 38 _k transversely to the transport direction, ie the smallest possible switchable unit in the transverse direction, eg. 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 38 _k or groups 38 _k to be activated based on the above-mentioned 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 location of at least three in the transverse direction, in particular equidistantly spaced from each other on the substrate 02 imprinted or aufzudruckender print elements 56, in particular the same print pixel 56, fixed and / or fixed. Using this information and taking into account the relative position between substrate 02 and dryer 14; 16; 36 at the site of action of the dryer 14; 16; 36, the positioning of the dryer elements 38 _k or the formation groups 38 _{k is} carried out or is carried out accordingly.

The information concerning the number and distribution of the picture elements 56 in the transverse direction can basically be obtained in any desired way and be 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.

Thus, a to be positioned group may, for example, 38 _k be selected 38 _k associated operating element 71 via a this group and as a left or right button effective controls 68 and / or as keys of a formed as an alphanumeric keypad controls 67 positioned laterally and / or positioned , In addition, not needed for the operation dryer elements 38 _k by selecting and then deactivation z. B. a correspondingly configured control element 79 can be deactivated or in the reverse manner, the required dryer elements 38 _k be activated by correspondingly reverse means of the control element 79. In the embodiment as an at least partially touch-sensitive operating interface 55, the aforementioned operating elements required for positioning can be encompassed by a same input or screen mask 84.

The configuration of the dryer device in the transport direction can be done in a simple variant on the Bedruckstofflänge L02 or a correlated with this size as a parameter. As a result, the length of the active phase P _AN covered by the sequence and corresponding to the stock length L02 is determined. It is a z. B. the parameter Bedruckstofflänge L02 representing control element 81 can be selected and its size z.

A configuration of the dryer device takes place here, for example, by drying elements 38 _k or 38 _k groups viewed transversely to the transport direction via manually operated controls 67; 68; 69; 71 are positioned. Possibly. can from a larger number of controls 67; 68; 69; 71 to be activated for the production dryer elements 38 _k or 38 _k groups are determined. This can be done positively by selecting the to be activated or negative by selecting the inactive dryer element 38 _k . The positioning of a dryer element 38 _k or a group 38 _k takes place z. B. by selecting the to be set dryer element 38 _k and the subsequent positioning on either the input of a specific position on the keys of an alphanumeric keypad or on the position to one or the other side changing button 68th

In a second example of the configuration of the dryer device using an operator interface 55 (see, for example, FIG. Fig. 22 ) Is carried out a dryer forming elements 38 _k or 38 _k groups according to the second embodiment of the desiccant 38 and the dryer 14; 16; 36. In a first variant, this configuration in the transverse direction can in principle likewise be effected directly via appropriately set operating elements 67; 68; 69; 71 _k for all dryer elements 38 or groups _can be made 38, for example as the first example except that in addition to the lateral position dryer elements 38 or groups 38 _{k k} z. B. on more, in Fig. 20 not shown controls whose width is fixed. In this case, according to the specifications for position and wide groups, 38 _{k of} radiation sources 38 _{k, i} arranged next to one another are formed, which z. B. in the above manner in operation simultaneously and / or jointly switched on and off. The formation of the groups 38 _k could be carried out in the case of a touch-sensitive Control interface 55 alternatively by activation of individual radiation sources 38 _{k, i} or radiation segments from the totality of the radiation sources 38 _{k, i} or radiation segments shown side by side in a screen mask. This can be z. B. at less high resolution, ie at a transversely lower total number and / or each greater width of radiation sources 38 _{k, i} or radiation segments be applicable.

However, in particular in the case of greater resolution and / or reduced positioning effort, a variant is advantageous in which the lateral position and width of a group 38 _k or track t _i or possibly even more groups 38 _k or tracks t _i relative to only a benefit is defined 57, and based on this related benefit definition using the number and position of the arranged adjacent to each other on the substrate 02 Take 57 information concerning the position and width of all necessary group 38 _k or tracks t _i is determined. The information concerning the number and position of the utility 57 arranged side by side on the printing substrate 02 can be present or given in a variety of ways. For example, information on the number N _x and width B 57 of the substrate 57 to be arranged laterally next to one another on the printing material 02 or the width B02 of the printing material 02 receiving the N _x benefits 57 can be used for this purpose. For the indication z. B. appropriately configured controls 74; 76; 72 may be provided. If the printing material 02 to be acted upon and / or the overall printing image is not symmetrical to the transverse extent of the dryer 38 and / or the machine center M, an indication of the corresponding lateral offset Δ _M can be additionally given over z. B. another control 73 may be provided.

The definition of the width and position of a group 38 _k or track t 1 to be activated, which is based on a utility 57, can take place via a specific activation of individual radiation sources 38 _{k, i} or radiation segments. In the case of a touch-sensitive screen 55 this can be a direct selection of an image of a Use 57 radiation sources 38 _{k, i} or radiation segments shown in the transverse direction to scale. The selection can be made in the case of a touch-sensitive screen 55 by touch. Alternatively, however, it may also be provided that the definition of the group 38 _k or track t _i relating to the utility 57 is defined by the definition of the two ends, ie the radiation sources 38 _{k, i} or _{k which} terminate the group 38 _k or track t _i on both sides Radiation segments, takes place. In a first variant, this can again be done by touching the respective boundary radiation sources 38 _{k, i} or radiation segments. In another variant, radiation sources 38 _{k, i} or -radiation segments -. B. as boundary radiation sources e ₁ ; e ₂ or boundary radiation segments - via appropriately configured controls 77; 78; 67; 68, for example by selecting the parameter to be defined parameter control element 77; 78, z.

B. buttons on an alphanumeric keypad or on the position to one or the other side changing buttons 68th

In the second example for the configuration of the dryer device, the configuration of the dryer device in the transport direction can take place in a simple variant over only the printing material length L02 or a variable correlated therewith. For this purpose, a z. B. the parameter Bedruckstofflänge L02 representing control element 81 can be selected and its size z. B. via effective as a plus or minus button controls 69 and / or adjustable as buttons of a trained as alphanumeric keypad controls 67 and variable. As above, the controls relating to the indication of the stock length L02 may be from the same or a different input or screen mask 85; 86 includes.

In a development, it can be provided that the configuration of the dryer device in the transport direction, the definition of several active phases P _AN each Cycle Z, in particular per substrate length L02 allowed. For example, the drying device can be configured in the longitudinal direction in such a way that at least one active phase P _{AN is} provided on a substrate 57 L02 arranged one behind the other.

This configuration in the longitudinal direction can in a first variant basically directly via appropriately configured controls 67; 68; 69; 71 take place for all active phases P _{AN of} the cycle Z, wherein for each of the phases P _AN their position in the transport direction and the width thereof via appropriate controls should be specifically definable. In the case of a touch-sensitive operating interface 55, the definition of the formation of the phases P _AN could alternatively be made by selecting or defining individual longitudinal sections from a total length of a printing material sheet 02 shown in a screen mask.

However, in particular for a reduced actuating effort, a variant is advantageous in which the position in transport or longitudinal direction and the width of a phase P _AN or possibly even several phases P _{AN is defined} based on only one use 57 and based on this one Using the information related to the number and position of the information arranged successively on the printing substrate 02, the position and length of all the active phases P _{AN are} determined. The information relating to the number and position of the utility 57 arranged one behind the other on the printing substrate 02 can be present or given in a variety of ways. For example, for this purpose, information on the number N _Y and length L57 of the useful substance 57 to be arranged on the printing substrate 02 or the length L02 of the printing material 02 successively receiving the N _Y Nutz 57 can be used. For the indication z. B. appropriately configured controls 74; 76; 72 may be provided. If the printing material 02 to be applied and / or the overall printing image are not symmetrical to the transverse extent of the drying agent 38 and / or to the machine center M, an additional indication of the corresponding lateral can be provided Offset Δ _M over z. B. another control 73 may be provided.

The definition of the length and position of a phase P _AN related to a utility 57 can in principle be made by way of a concrete specification of the individual phases P _AN . In the case of a touch-sensitive screen 55, this may be a direct selection of portions of a tape that is scaled down to a longitudinal direction of an image of a utility 57. The definition can be made in the case of a touch-sensitive screen 55 by touch. Alternatively, however, it may also be provided that the definition of the phase P _ON related to the use 57 is made by the definition of the two ends of the active phase P _AN . This can be done in a first variant again by touching corresponding locations on the above-mentioned band.

B. the front or the rear end of the active phase to be defined P _AN control element, and its definition via either the input of a specific relative position z. B. buttons on an alphanumeric keypad or on the position to one or the other side changing buttons 68th

As far as the configuration in the transverse direction is concerned, 57 or one or more groups 38 _k can be formed per use. If, for example, each of the two or even more pixel elements 56 or picture element groups to be dried is drying, the distance justifying a differentiation, for example, two or even more groups _{38k may be} definable for drying the two or more picture elements 56 or picture element groups (see eg Fig. 23a ). However, if two picture elements 56 or picture element groups are close to each other, only one group 38 _k can be defined for their drying. In the event that the use of 57 picture elements 56 or picture element groups is to be dried in the area of both lateral ends, the groups 38 _{k of} mutually adjacent ends can become continuous groups 38 _k (see, for example, Fig. 23b ).
