1. Field of the Invention
The invention is directed to a method for producing a printed product.
2. Description of the Related Art
Web presses have printing form-based printing units for statically printing at least one printing substrate web with a printed image which is the same for all printed copies of a printed product. Every printed copy usually comprises a plurality of printed pages.
Such known form-based printing units, which serve for static printing on the printing substrate web, or on each printing substrate web, are typically constructed as offset printing units. It is also possible that printing form-based printing units are constructed as intaglio printing units.
It is already known in practice to provide in a web press, in addition to the printing form-based printing units serving for static printing of the printing substrate web, or of each printing substrate web, with a printed image which is the same for all printed copies, at least one printing device having no printing form so as to individualize printed copies in addition to, particularly in-line with, the static printing, i.e., to dynamically print at least one printing substrate web with a printed image which varies for at least some printed copies.
A printing device of this kind without a printing form can be an inkjet printing device or an electrophotographic printing device, such as a laser printing device or an ionographic printing device.
When a printed product is produced on a web press in accordance with known practices in that a plurality of printing substrate webs are statically printed by printing form-based printing units and in addition to this, particularly in-line therewith, at least one of the statically printed printing substrate webs is dynamically printed by a printing form device having no printing form, a printed product is always produced in which the dynamic printing is formed at the finished printed product on an outer page of the printed product and is accordingly visible from the outside without unfolding the printed product. However, when printing in this matter, products can be individualized only to a limited extent.
It is therefore an object of the present invention to provide a method for producing a printed product.
This and other objects and advantages are achieved in accordance with the invention by a method in which printing substrate webs that are to be printed are held ready at a plurality of reel splicers of a web press, wherein the plurality of printing substrate webs are transported respectively through at least one printing form-based printing unit of the web press for static printing of the plurality of printing substrate webs with a printed image remains unchanged for printed copies of the printed product. In addition to, particularly in-line with, the static printing, at least one of the statically printed printing substrate webs is printed dynamically in the region of at least one printing device of the web press without a printing form with a printed image which is variable for at least some printed copies. Statically printed printing substrate webs and statically and dynamically printed printing substrate webs are joined and processed to form a multi-page printed product in the region of at least one turning and mixing stage and at least one folder of the web press such that the printed product is dynamically printed on at least one printed page of the printed product inside of the printed product.
In accordance with the method of the invention, a printed product is provided such that a plurality of printing substrate webs are statically printed by printing form-based printing units, at least one of the statically printed printing substrate webs is printed dynamically by at least one printing device having no printing form, and statically printed printing substrate webs and statically and dynamically printed printing substrate webs are joined and folded such that the printed product is dynamically printed on at least one inside page of the printed product. Here, the dynamic printing of the printed product is only visible to a purchaser of the printed product when the purchaser unfolds the printed product. This is entirely unknown in the art.
Other objects and features of the present invention will become apparent from the following detailed description considered in conjunction with the accompanying drawings. It is to be understood, however, that the drawings are designed solely for purposes of illustration and not as a definition of the limits of the invention, for which reference should be made to the appended claims. It should be further understood that the drawings are not necessarily drawn to scale and that, unless otherwise indicated, they are merely intended to conceptually illustrate the structures and procedures described herein.
Embodiment examples of the invention are described more fully with reference to the drawings without limiting the invention, in which:
The present invention is directed to a method for producing a printed product on a web press. As shown in
All of the printing form-based printing units 120 share the common feature that they serve to provide static printing of the printing substrate webs with a printed image that stays the same for the printed copies of a print job.
After the static printing of the plurality of printing substrate webs, at least one of the statically printed printing substrate webs 115-1, 115-2, in addition to, particularly in-line with, the static printing, is printed dynamically in the region of at least one printing device 130 of the web press without a printing form with a printed image which is variable for at least some printed copies. Here, a plurality of printing substrate webs are preferably dynamically printed respectively by at least one printing device 130 without a printing form. In
The printing devices 130 without printing forms are preferably inkjet printing devices. Alternatively, they can also be electrophotographic printing devices, such as laser printing devices or ionographic printing devices. It is also possible to use different printing devices without printing forms in a web press for dynamic printing of at least one printing substrate web.
In the region of the printing device 130 without a printing form, or of each printing device without a printing form, at least one printing substrate web 115-1, 115-2 is printed with a dynamic printed image, where the dynamic printed image is text, pictures, numbers and/or codes, such as barcodes. The dynamic printing in the region of the printing device without a printing form, or of each printing device 130 without a printing form, can be performed with one or more colors.
Preferably, printing substrate webs with a width greater than one meter are printed in the printing form-based printing units 120 and in the printing devices 130 without a printing form.
Preferably, at least two pages, i.e., at least four pages, preferably at least six pages, are printed side by side on a printing substrate web considered in the axial direction of the printing substrate web.
The static printing and the dynamic printing of the printing substrate webs 115-1, 115-2 is performed at a printing speed of at least 7 m/sec, preferably at a printing speed of at least 10 m/sec. When the static printing and the dynamic printing is performed in-line, the static printing and dynamic printing are performed at the same printing speed.
In the region of at least one turning and mixing stage 140 and at least one folder 150 of the web press, statically printed printing substrate webs 115-3 and statically and dynamically printed printing substrate webs 115-1, 115-2 are joined and processed, i.e., folded, to form a multi-page printed product 160 such that the printed product is dynamically printed on at least one page of the printed product located inside the printed product. The dynamic printing can be performed on a plurality of inner pages and optionally also on at least one outer page of the printed product.
The method is preferably used for producing a newspaper. A newspaper typically comprises one or more books, each book comprising a plurality of outer printed pages and a plurality of inner printed pages. Within the meaning of the invention, a newspaper is produced such that at least one inner page of the book is dynamically printed in the region of at least one book of the newspaper.
The image is dynamically printed on at least one of the statically printed plurality of printing substrate webs in a region of at least one printing device of the web press without a printing form, as indicated in step 230. In this case, the printed image is variable for at least some printed copies.
The statically printed plurality of substrate webs and the at least one statically and dynamically printed plurality of printing substrate webs are joined and processed to form a multi-page printed product in the region of at least one turning and mixing stage and at least one folder of the web press such that the multi-page printed product is dynamically printed on at least one printed page of the printed product located inside of the printed product, as indicated in step 240. Thus, while there have been shown, described and pointed out fundamental novel features of the invention as applied to a preferred embodiment thereof, it will be understood that various omissions and substitutions and changes in the form and details of the devices illustrated, and in their operation, may be made by those skilled in the art without departing from the spirit of the invention. For example, it is expressly intended that all combinations of those elements and/or method steps which perform substantially the same function in substantially the same way to achieve the same results are within the scope of the invention. Moreover, it should be recognized that structures and/or elements and/or method steps shown and/or described in connection with any disclosed form or embodiment of the invention may be incorporated in any other disclosed or described or suggested form or embodiment as a general matter of design choice. It is the intention, therefore, to be limited only as indicated by the scope of the claims appended hereto.
