摘要:
A method for producing a printed product on a web press, wherein a plurality of printing substrate webs which are to be printed are held ready at a plurality of reel splicers of the web press. The plurality of printing substrate webs are transported respectively through at least one printing form-based printing unit of the web press for the static printing of an image on the plurality of printing substrate webs which does not change 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 an image which is variable for at least some printed copies, and 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 located inside of the printed product.

A method for producing a printed product, wherein at least one printing substrate webs are transported through at least one printing form-based printing unit for static printing of at least one printing substrate webs with a printed image which remains unchanged for printed copies of the printed product. In addition, at least one of the statically printed printing substrate webs is printed inline dynamically with the static printing in a region of at least one printing device of the web press without a printing form with access data, e.g., a prize code, which is individualized for at least some printed copies. Here, information content, such as a prize, which extends beyond the printed product can be accessed by the access data for a purchaser of the printed product over an interactive medium, such as the Internet. Access data specific to a target person and/or a target group are printed in the printed copies as individual access data.

A method for printing a substrate web in a rotary printing press is disclosed. The substrate web to be printed is conveyed through a printing form-based printing unit for static printing of the substrate web with a print image that does not vary for the print copies of a printing job, such that at least one static print page is printed in the longitudinal direction of the substrate web per revolution of the form cylinder and several static print pages are printed on the substrate web across the longitudinal direction of the substrate web. In addition to static printing, the statically printed substrate web is printed dynamically with a variable print image in the area of a printing form-free printing device of the rotary printing press such that the print format of the printing form-free printing device extends in at least some sections over at least two statically printed pages.

A method for controlling a printing process is disclosed. The method includes printing a printing material by a printing unit on a basis of data of a prepress stage. A printed result on the printing material is compared with a desired value and a correction value is derived from the comparison. The data of the prepress stage is corrected with the correction value.

A rotary printing press is disclosed. The press includes at least one plate-free printing unit for printing a substrate web with a static print image for print copies of a print job and at least one plate-free printing unit, in particular an inkjet printing unit for printing the substrate web with a dynamic print image. The/each plate-free printing unit can be shifted from a printing position in which the substrate web can be printed by the same printing unit, into a service position in which no substrate web can be printed by the same printing unit. A device which is assigned to the service position is printable by at least one plate-free printing unit that is shifted into the service position, such that the printing parameters of the same can be verified and adapted to subsequent printing of the substrate web in the printing position.
摘要:
The invention is directed to a method for controlling an inkjet printing device working according to the continuous inkjet principle so that a print image to be printed by the inkjet printing device can be positioned on a substrate. The inkjet printing device supplies ink droplets at a determined droplet generating frequency, and the position of the substrate to be imprinted relative to the inkjet printing device is monitored by means of a sensor, in particular by means of an encoder, in order to generate an actuating signal for the inkjet printing device. According to the invention, the absolute position of the substrate is monitored by means of the sensor, and when the sensor detects the start of a substrate zone to be imprinted with a relatively high printing quality, the actuating signal of the inkjet printing device for the subsequent substrate zone to be imprinted with the relatively high printing quality is coupled with the droplet generating frequency, and when the sensor detects the end of a substrate zone to be imprinted with the relatively high printing quality, the actuating signal of the inkjet printing device for the subsequent substrate zone which is not to be imprinted or is to be imprinted with a relatively low printing quality is coupled with the sensor signal.

A method for the printing of a print fabric is disclosed. Output data, more preferably an output matrix of a print image to be printed with an inkjet printing device is converted to target data, more preferably a target matrix, for controlling the inkjet printing device in real time dependent on a current printing speed, a current drop frequency of the inkjet printing head of the inkjet printing device, and a current inclination angle of the nozzle row of the inkjet printing head relative to the transport direction of the print fabric prior to transmitting the data to the inkjet printing device.
摘要:
A method for printing a printing substrate is disclosed. The printing substrate is printed by a printing-plate-based printing method, in particular by an offset printing method, with a printed image that is the same for printed copies of a print job and therefore with a static printed image as well as, in addition to the printing-plate-based printing method, by a non-printing-plate-based printing method, in particular an inkjet printing method, with a printed image that is variable for the printed copies of the print job and therefore with a dynamic printed image. After the static and dynamic printing of the printing substrate, each printed copy is detected using measuring techniques and recorded at least in sections in such a manner that each printed copy is verifiable with respect to its authenticity.
摘要:
A method for reducing the strikethrough effect in inkjet printing on thin substrates is disclosed. The method includes determining a normal print quality; determining a normal quantity of ink which would be used for inkjet printing of a certain print image on a strikethrough-resistant substrate, based on the normal print quality; determining a minimal print quality for the print image to be printed; determining a maximal value for the strikethrough effect; reducing the normal quantity of ink to a reduced quantity of ink, so that the print image has at least the minimal print quality and the maximal value of the strikethrough effect is not exceeded.
