Description

[0001] The invention relates to a modular production system for processing and / or finishing a printing medium, comprising several modular units.

[0002] Furthermore, the invention relates to a method for processing and / or finishing a printing medium.

[0003] Finally, the invention relates to a fragrance module unit for processing and / or finishing a print carrier.

[0004] Production printing systems and methods of the type in question for processing and / or finishing a print substrate have been known in practice for years. Thus, there are various techniques and options within the scope of print processing and finishing to provide an attractive, high-quality print product tailored to the respective target group, depending on the intended use. Print finishing can involve altering the surface of a print product, which can be carried out inline (in the printing press) or in a subsequent process. Different finishing effects can alter the structure, the visual and tactile impact of the material. Print finishing can offer various options for individual design; for example, the paper as a print substrate can be coated using various processes.This means that print products can be enhanced through print finishing, making the corresponding advertising materials appear more valuable.

[0005] In practice, there is often a need to create a print product that is as personalized as possible, which can be used to differentiate the company from competitors on the market through high quality and innovation.

[0006] In addition to various types and options of print finishing, whereby special effects can be created or produced using special varnishes (dispersion varnish, UV varnish, relief varnish, etc.) or special embossing (blind embossing, relief embossing, steel engraving, etc.), it is also known in practice to add a fragrance to the print product.

[0007] Especially for communication, it is essential that images remain in the memory longer when perceived in conjunction with scents. Scent significantly enhances recall. A multi-sensory approach, for example, can significantly increase the spontaneous purchase rate of scented product packaging. At the same time, certain emotions are conveyed. Thus, an advertising message with scent arouses emotions and curiosity, thus enhancing the perception of the recipient.

[0008] For example, scented papers are known to be used as a sales tool. To produce scented paper, scented pigments are incorporated into a special paper using a special, complex coating process to ensure the aroma is long-lasting. When the scent comes into contact with the air, it can release automatically. However, the production of such scented papers is complex and expensive, making the use of such printed products disadvantageous.

[0009] Furthermore, print finishing of print products with scented varnishes is known in practice. A scented varnish is an effect varnish that is provided with microencapsulated aromas and is applied to the printed product as the final layer. The aromas or essential oils thus enclosed are applied directly with the varnish to be printed onto the print product. When pressure is applied, friction is applied, or a print medium coated with this scented varnish is opened, these capsules burst and release a scent. However, a disadvantage of using scented varnishes is that corresponding scented varnishes are expensive. Another problem is that pressure or abrasion on the already finished product is difficult or impossible to avoid during further processing. This destroys the microcapsules contained in the varnish. During the feeding or transport of a print medium / substrate, as well as during any folding, stapling, enveloping, etc.The mechanical stress on the print carrier / substrate is so severe that the microcapsules contained in the varnish are destroyed at this point. Furthermore, printing should not be repeated on the varnish that has already been printed. This also makes it impossible to print on the back, as this would cause the capsules on the front to burst.

[0010] DE 100 02 739 A1 discloses a machine for double-sided dyeing of paper webs. The known machine consists of at least two consecutively arranged color printing units of the same design. The machine for double-sided dyeing of paper webs can be used to apply fragrances and adhesives to paper webs made of various paper grades and paper-like materials such as wallpaper and corrugated cardboard.

[0011] DE 198 26 505 A1 discloses a method and a device for printing surfaces of printing materials, in particular using a modified offset printing machine, wherein a material applied to a printed product can contain microencapsulated fragrances.

[0012] Document DE 102 06 601 A1 discloses a method and a device for producing a barrier layer on a carrier material or a packaging material. The barrier layer is applied to the carrier material, whereby the barrier layer is designed to be grease-proof. The end product produced in this way is used as packaging material or for the packaging of food, cosmetics, or pharmaceuticals. The solution for producing the barrier layer can contain flavorings and / or fragrances.

[0013] WO 2008 / 132185 A2 relates to a non-corrugating printed substrate and a corresponding manufacturing method therefor.

[0014] The present invention is based on the object of designing and developing a modular production system and a method of the type mentioned at the outset for processing and / or finishing a print carrier in such a way that the most efficient and / or flexible fragrance finishing of the print carrier is possible using structurally simple means, in particular with regard to the most efficient and flexible processing chain through the production system.

[0015] According to the invention, the above object is achieved by the features of claim 1. This object is achieved by a modular production system for processing and / or finishing a print medium comprising a plurality of module units, wherein the module units comprise a fragrance module unit configured to apply a fragrance to the print medium, wherein the fragrance module unit is configured to serve as a remoistening unit for the print medium.

[0016] The above object is further achieved by a method having the features of claim 10. This method provides a method for processing and / or finishing a print carrier with a production system comprising several modular units, wherein a fragrance module unit is used to apply a fragrance to the print carrier, and wherein the fragrance module unit, which is designed to serve as a remoistening unit for the print carrier, is used to remoisten the print carrier.

[0017] Finally, the above object is achieved by a fragrance module unit having the features of claim 16. This provides a fragrance module unit for a production system according to the invention, which comprises means for applying a fragrance to the print carrier, wherein the fragrance module unit is designed such that it serves as a remoistening unit for the print carrier.

[0018] According to the invention, it has been recognized that it is significantly advantageous if, with regard to scenting the print medium (i.e., providing the print medium with a fragrance), the scenting process (i.e., the process of applying the fragrance to the print medium) is carried out by means of a module unit specifically provided or designed for this purpose. Accordingly, the print medium is not provided with a fragrance as part of the actual printing process in which text and / or image content is printed onto the print medium, but rather as part of a separate scenting process by the fragrance module unit. This provides significantly more flexibility and efficiency with regard to the handling of the production system, in particular with regard to the processing chain to be carried out by the production system. The scenting process can thus take place independently and detached from the printing process.For example, the fragrance module unit can be used to provide the print substrate with only a fragrance during a fragrance application process, in such a way that neither optical nor haptic effects are created on the print substrate, as would be the case when using a fragrance varnish.

[0019] Since the fragrance can be applied to the print substrate in liquid and / or gaseous form, particularly as aerosols, the resulting print substrate is virtually "invisible." No rubbing is required. Rather, a print substrate can be created that creates neither a visual nor a tactile impairment, as is the case with a scented varnish, for example. By using flavorings or essential oils, a wide variety of fragrances are conceivable that could be used to scent the print substrate.

[0020] It should be noted here that a print medium can be any print product. The print medium (printing material or substrate) can also be a component of a print product produced by the processing chain of the modular production system. In the simplest case, it could be paper, which is conveyed as a print medium through the individual modular units of the production system. The print medium can therefore be a material that can be printed using various printing processes, i.e., a material that can be printed using known technical processes. Examples could be paper, cardboard, foil, metal, and / or textiles (photo canvas), etc.

[0021] Furthermore, it should be noted that a production system—particularly within the scope of the claims and preferably within the scope of the description—is to be understood as a system for processing and / or finishing a print medium or substrate in the broadest sense. A production system can preferably be understood as a production printing system, where, in addition to printing on a print medium, further processing steps can also be performed. A wide variety of printing technologies can be considered for the production printing system. For example, digital printing is conceivable here, possibly in the office sector, etc.

[0022] A fragrance module unit according to an embodiment of the invention can also be used or integrated into offline or near-line processes and / or post-press systems as a further processing system or production system. Examples of possible applications include brochure makers, hot-melt gluing, stapling, folding, varnishing, and / or enveloping systems or finishers.

[0023] The fragrance module unit can advantageously be designed as a separate module unit. It is conceivable that the fragrance module unit could be used as an independent module unit within the scope of offline processing / finishing or in the offline process (also called nearline process). Accordingly, the fragrance module unit can be used as an isolated processing station for finishing the print medium.

[0024] Furthermore, it is conceivable that the fragrance module unit could be used as a separate module within inline processing / finishing or in an inline process. With inline processing, the process of scenting the print substrate via the fragrance module unit takes place directly within the printing press or production system. This means that the fragrance module unit can be permanently linked or coupled to the printing press as a separate module unit, but forms its own module unit as a separate, possibly replaceable, component of the overall processing chain of the modular production system. Thus, the fragrance module unit can be arranged within a processing chain of modular units for printing, varnishing, folding, stitching, and / or quality control, etc.The modular integration of the fragrance module unit into the modular production system enables flexible and variable installation and deinstallation of the fragrance module unit in the production system.

[0025] In an advantageous embodiment, the fragrance module unit can be arranged downstream of a printing module unit for printing the print medium within the production system's processing chain. Thus, the fragrance module unit's scenting process for the print medium can be arranged downstream of the printing process, which is carried out by a corresponding printing module unit. Within the processing chain, the print medium can be guided or conveyed through the individual module units of the production system and thus processed or finished sequentially to ultimately provide a finished, high-quality, and optionally customized print product.

[0026] According to the invention, the fragrance module unit is designed to serve as a remoistening unit for the print medium. This ingenious combination allows both remoistening and scenting of the print medium to be achieved in one module unit. The fragrance can expediently be applied to the print medium in liquid form and / or as an aerosol. In various printing processes, the inks dry, which can lead to considerable problems during further processing. By the fragrance module unit carrying out remoistening and thus functioning as a remoistening unit, the water content in the paper or print medium can be increased to the required value after drying. The front and back of the print medium or printing paper can advantageously be moistened in order to smooth the print medium.Both sides of the printing substrate can be conveniently moistened evenly. The particular benefit lies in the improved runnability of the remoistened printing substrates / papers. Fewer web breaks and higher speeds result, both during printing on the printing substrate and in subsequent finishing processes within the print production system. This enables a more efficient process.

[0027] The following advantages are possible, for example, through re-moistening or re-wetting of the print medium, preferably electrostatically: - significantly less waviness during adhesive binding - no fiber breakage in the fold - no outgrowth of the trimmed products - no climate waves

[0028] The performance of the production system can therefore be increased by remoistening the paper with the fragrance module. Remoistening the paper can effectively prevent the occurrence of waviness and curling of the printing substrate (e.g., a printed sheet) through moistening.

[0029] With regard to scenting the print medium using simple structural means, the fragrance module unit can have at least one contact roller. The contact roller is designed and arranged in the fragrance module unit such that the fragrance is applied to the print medium via the contact roller. The fragrance can expediently be in liquid form. The contact roller is wetted with the liquid fragrance and then serves to apply the fragrance to the print medium. The contact rollers can expediently be arranged such that the print medium is conveyed over the contact rollers. Furthermore, it is conceivable that the print medium is conveyed or moved, for example, through two opposing contact rollers, and that the liquid fragrance is applied to the print medium, on both sides or one side. This enables simple and efficient application of the printing material to the print medium.

[0030] Advantageously, the fragrance module unit can have at least one wetting roller. The wetting roller is designed to wet a contact roller with the, preferably liquid, fragrance. Depending on the number of contact rollers used, it is conceivable that at least one wetting roller is provided for each contact roller in order to wet or supply the contact rollers with the liquid fragrance.

[0031] In an advantageous embodiment, the fragrance module unit can comprise a liquid bath that provides the fragrance in liquid form. In this case, it is conceivable, for example, that the print carrier is brought into direct contact with the liquid bath in order to apply the fragrance to the print carrier. Furthermore, it is conceivable that application means of the fragrance module unit are in contact with the liquid bath in order to supply the application means with the fragrance, whereby the application means can then in turn supply the print carrier with the fragrance directly or indirectly. It would also be conceivable for a wetting roller to absorb the fragrance via the liquid bath and then wet the contact roller with the fragrance, so that the contact roller can then apply the fragrance to the print carrier.In any case, the fragrance in the fragrance module unit can be provided via the liquid bath, which is designed, for example, as a liquid container.

[0032] In an advantageous embodiment, the fragrance module unit can comprise a spraying device, wherein the spraying device is designed to spray the print carrier with the fragrance or to mist the print carrier with the fragrance. This enables simple and efficient application of the fragrance to the print carrier.

[0033] With regard to the availability of the fragrance, the fragrance module unit can comprise a tank device for storing the fragrance. Advantageously, the tank device can comprise a magazine of several tank containers. Thus, several and diverse fragrances can be stored by the tank device and made available as needed for scenting the print medium. The fragrance can preferably be stored in the tank device in liquid form. It is conceivable that the application means of the fragrance module unit are supplied with the fragrance via the tank device. Furthermore, it is conceivable that the tank device serves to supply or fill the liquid bath with the fragrance as needed.Particularly in a variant with a tank device that comprises a magazine of several tank containers, it is ingeniously possible that, as required, the liquid bath is filled with the desired fragrance and / or the application means of the fragrance module unit are supplied with the desired fragrance directly or indirectly.

[0034] In an advantageous embodiment, the fragrance module unit can include a cleaning device. The cleaning device can, for example, pump out and / or rinse and / or fill the liquid bath or a container used to provide a fragrance. Thus, the fragrance module unit can be filled and operated with different fragrances as needed. In any case, a simple change of different fragrances for the fragrance module unit is possible. This can also include returning the fragrance to the tank device for further storage.

[0035] In an advantageous embodiment, the fragrance can be applied to the print substrate by the fragrance module unit using a print head. This could be achieved, for example, with an inkjet print head. This provides an efficient design for an application means for the fragrance module unit.

[0036] In an advantageous embodiment, it is conceivable for the fragrance to be mixed with a preferably odorless ink. The ink can then be printed onto the print substrate along with the fragrance. This ensures the most efficient possible application of the fragrance to the print substrate.

[0037] In an advantageous embodiment, the fragrance module unit can comprise a separate printing unit. This could, for example, be a printing unit based on offset printing technology. The printing unit uses a dampening solution during operation, with the fragrance being mixed into the dampening solution in a sophisticated way. Thus, it is conceivable for a separate printing unit to run in offset printing, which then runs in "idle" mode, so to speak, with the liquid fragrance instead of the usual dampening solution or the usual aqueous solution. This creates an efficient design for an application means for the fragrance module unit.

[0038] In an advantageous embodiment, the preferably liquid fragrance can be applied to the printing carrier by means of a screen printing process.

[0039] There are now various possibilities for advantageously embodying and developing the teaching of the present invention. For this purpose, reference is made, on the one hand, to the claims subordinate to claims 1 and 10 and, on the other hand, to the following explanation of preferred embodiments of the invention with reference to the drawing. In conjunction with the explanation of the preferred embodiments of the invention with reference to the drawing, generally preferred embodiments and developments of the teaching are also explained. The drawing shows the only Fig. in a schematic view a modular production printing system as a production system according to an embodiment of the invention.

[0040] The single figure shows a modular production printing system 1 comprising several modular units for processing and / or finishing a print medium. The print medium can be any print product and / or a component of a print product that is produced by the production printing system 1's processing chain or completed by processing / finishing. In the simplest case, this could be paper, which is transported as a print medium through the individual modular units of the production printing system 1. Depending on the modular unit, the print medium undergoes appropriate processing or finishing.

[0041] The production printing system 1 comprises a printing module unit 2, a fragrance module unit 3, a folding and punching module unit 4, and a stapling module unit 5. The printing module unit is used to print text or images onto the print substrate. This can also include the application of various varnishes to the print substrate. Additional modules can be coupled to the production system 1 or, as required, replaced or completely removed.

[0042] Due to the modular design of the production printing system, additional and / or alternative modular units are conceivable, for example, a booklet finisher and the like. The arrangement of the fragrance module unit 2 according to the invention within the production printing system 1 can also vary. In particular, due to its installation as a separate fragrance module unit, it can - in principle - be arranged at any point in the processing chain.

[0043] The fragrance module unit 2 serves to apply a fragrance to the print substrate. The fragrance module unit 2 comprises a tank device 6 with several tank containers 7, 8, 9, and 10 for storing several different fragrances. The fragrance is applied to the print substrate via application means 11. The application means 11 can comprise various rollers and / or a liquid bath, which are / are designed to provide the print substrate with the fragrance. Furthermore, a spray device is also conceivable as the application means 11.

[0044] Because the fragrance is applied to the print substrate in liquid and / or gaseous form, particularly as aerosols, the resulting print substrate is virtually "invisible." No rubbing is required, as is the case with an applied scented varnish containing microencapsulated aromas.

[0045] The tank device 6 serves to supply the application agent 11. Furthermore, the fragrance module unit 3 includes a cleaning device 12. The cleaning device 12 serves to clean the application agent 11 so that the fragrance can be changed depending on the application. This allows the fragrance module unit 3 to be filled and operated with different fragrances as needed. This ensures easy changing of the fragrances for the fragrance module unit 3.

[0046] After the print medium has been scented, the scented (scented) print medium can be transported to other module units within the print production system 1 and further processed or refined there. However, it is also conceivable for the scent module unit 3 to be arranged at a different point, for example, at the last point, in the processing chain. It is advantageous if the scenting process takes place after the actual printing process of the print module unit 2. However, due to the modular implementation, it would also be possible to place the scent module unit 3 upstream of the print module unit 2.

[0047] With regard to further advantageous embodiments of the production system according to the invention and the method according to the invention, reference is made to the general part of the description and to the appended claims in order to avoid repetition.

[0048] Finally, it should be expressly pointed out that the embodiments of the device according to the invention described above serve only to explain the claimed teaching, but do not limit it to the embodiments.
