Description
[0001] This application claims priority under 35 U.S.C. .sctn.119
to patent application no. DE 10 2011 122 520.3, filed on Dec. 29,
2011 in Germany, the disclosure of which is incorporated herein by
reference in its entirety.
BACKGROUND
[0002] The disclosure relates firstly to a method for equipping a
material web processing machine with regard to material webs to be
processed, in which the material web processing machine is set as a
function of material web processing-specific parameter data in
order to be able to process the respective material web to be
processed in a job-individual manner with the material web
processing machine.
[0003] In addition, the disclosure secondly relates to an apparatus
for processing a material web with a material web processing
machine and with a device for controlling and/or regulating the
material web processing machine.
[0004] Furthermore, the disclosure relates to an arrangement
comprising an apparatus for processing a material web with a
material web processing machine and a digital press stage
apparatus, which generates and uses digital print job workflow data
to process the material web.
[0005] Moreover, the disclosure relates to the use of an electronic
data interface device.
[0006] Generic methods and apparatus for carrying out such methods
are already known from the prior art.
[0007] For example, laid-open specification DE 10 2005 056 802 A1
discloses a method for regulating the web tension of a material web
or product web moved by means of a transport device with a web
tension regulator while determining control loop parameters, which
method is distinguished by the fact that the control loop
parameters of the web tension regulator are determined in
accordance with a characteristic curve that can be predefined as a
function and/or on a plurality of reference points, by which means
an increase in the production quality with a simultaneously higher
production volume and little effort in converting a material web or
product type is made possible.
[0008] Furthermore, laid-open specification DE 10 2009 019 624 A1
discloses a method for determining at least one control parameter
of a control element in a web tension control loop for a processing
machine for processing a material web or product web, in which
method the at least one control parameter is determined as a
function of at least one parameter characterizing the material web
or product web, at least one parameter characterizing the
processing machine and at least one dead time. In this way,
regulation of the processing machine can advantageously be
performed, so that the production quality can also be improved.
[0009] Furthermore, laid-open specification DE 10 2010 013 782 A1
discloses a method for the automatic determination of at least one
controller parameter of a dancer position control element in a
processing machine for processing a material web and comprising a
dancer, the dancer position of which is measured, a rotational
speed of a roll being predefined on the basis of the measured
dancer position, the at least one controller parameter being
determined automatically as a function of a diameter of the roll.
By means of this method, automatic configuration of a dancer
position control system on a processing machine can be provided, by
which means the production quality can also be improved hereby.
[0010] By means of the solutions cited above, in particular the
production quality with regard to the processing of material webs
can easily be improved.
[0011] It is an object of the disclosure to develop generic methods
and apparatus further in order further to improve the operational
reliability, in particular when converting a material web type, and
therefore also the production quality.
SUMMARY
[0012] The object of the disclosure is achieved in a method for
equipping a material web processing machine with regard to material
webs to be processed, in which the material web processing machine
is set as a function of material web processing-specific parameter
data in order to be able to process the respective material web to
be processed in a job-individual manner with the material web
processing machine, according to the disclosure material web
processing-specific parameter data being received electronically in
an automated manner on the material processing machine by means of
an electronic data interface device and subsequently provided
electronically on a device for controlling and/or regulating the
material web processing machine.
[0013] As a result of the fact that necessary material web
processing-specific parameter data can be received or read in an
automated manner on the material processing machine by means of an
electronic data interface device, the danger of erroneous
allocation of material web processing-specific parameter data with
respect to a material web to be processed can be reduced
significantly, which means firstly that the operational reliability
in the procedure and secondly the production quality are
advantageously increased.
[0014] As opposed to the prior art, the necessary material web
processing-specific parameter data can advantageously be made
available in an automated manner on the material processing
machine. In particular, manual or by-hand input of parameter data
in this regard is no longer necessary, so that the material
processing machine can be operated substantially virtually fully
automatically.
[0015] Advantageously, it is cumulatively also possible to dispense
with production-dependent input of formulations with regard to a
configuration of appropriate setting values of an automation system
in conjunction with the present method.
[0016] Hitherto, it was often the case that such setting values on
a processing machine were originally even not changed as a function
of production, which normally also has a detrimental effect on the
production quality to be achieved on the material web to be
processed.
[0017] Hitherto, setting was often also carried out only via a
formulation management system stored on a machine control system or
on a higher-order management system. However, formulation data in
this respect likewise has to be entered by hand for the first time
before it can be used in the case of a repetition job. This also
increases the danger of an erroneous input.
[0018] To this extent, the object of the disclosure is also
achieved by the use of an electronic data interface device for the
electronic reading of digital print job workflow data from a
digital pre-press apparatus on a printing press for the automated
setting of material web processing machine parameters
characterizing the web run with regard to a material web to be
printed on the printing press. As a result of the use according to
the disclosure of the electronic data interface device, it is
advantageously possible ideally to dispense completely with an
input of data or information in this respect, previously necessary
by hand and, as a result, also lengthy and afflicted with
errors.
[0019] In the sense of the disclosure, the term "material web"
describes a product web which can be processed with the material
web processing machine and which, in particular with regard to its
material nature and dimensions, can be configured virtually as
desired. For example, the present material web is a material web
made of paper, film, material or the like to be printed.
[0020] In this case, it is exceedingly advantageous if, by using
the material web processing-specific parameter data received
electronically or digitally, material web processing machine
parameters characterizing the web run of unwinding roll devices,
winding roll devices and/or controlled or regulated material web
pull-roll devices are set.
[0021] A substantial constituent part of the present disclosure can
also be seen in the fact that material web processing machine
parameters characterizing the web run are generally determined
electronically from existing digital job workflow data or
specifically from digital print job workflow data, as will be
described more extensively below.
[0022] The term "material web processing machine parameters
characterizing the web run" in the sense of the disclosure
substantially describes parameters for controlling or regulating
functional components or functional subassemblies which have an
effect on the treatment of the respective material web by or with
the present material web processing machine.
[0023] Particularly advantageously, shafts of the material web
processing machine that transport a material web can be set by the
present method.
[0024] In particular, the unwinding and winding roll devices can in
this case be operated for example in the operating modes "winder
with dancer position regulator", "winder with force transducer and
web force regulator with torque control", "winder with force
transducer and web force regulator with rotational speed control",
"sensor-less winder with torque control".
[0025] Shafts transporting a material web, such as in particular
the material web pull-roll devices, can be operated here, for
example, in the operating modes "shafts which always run in an
unchanged ratio with respect to the machine speed, i.e.
uncontrolled or unset shafts", "shafts which run in a predefined
ratio with respect to the machine speed" (set shafts), and "shafts
which run in a ratio with respect to the machine speed predefined
by a controller" (controlled shafts of a material web draw
controller).
[0026] Both the aforementioned winding roll device, also called a
winder for short, and the controlled or set shafts transporting the
material web or, in the present case, also called material web
pull-roll devices, contain parameters here, for example control
parameters, which have to be changed or should be changed as a
function of production in order to be able to achieve a high
production quality. This can advantageously be carried out in an
automated manner with the present method according to the
disclosure.
[0027] It goes without saying that the present method can
advantageously be employed on any material web processing machines
on which recourse is made to material web processing-specific
parameter data from a previous operating process, and on which the
material web processing-specific parameter data can be used in a
subsequent processing process on the material web processing
machine.
[0028] Particularly advantageously, however, the present disclosure
can be employed in conjunction with printing presses for printing
material webs.
[0029] The object of the disclosure is also achieved by an
apparatus for processing a material web with a material web
processing machine and with a device for controlling and/or
regulating the material web processing machine, the apparatus
having an electronic data interface device for the electronic
reception of digital pre-press data from a digital pre-press
apparatus, by means of which material web processing-specific
parameter data can be provided electronically to the device for
controlling and/or regulating the material web processing
machine.
[0030] In this way, because of a lower danger of input errors, the
production quality with regard to the material webs to be processed
can be increased considerably.
[0031] In particular, however, the method according to the
disclosure can also advantageously be carried out with the present
apparatus.
[0032] By means of the material web processing-specific parameter
data, in particular a motion control device for controlling and/or
regulating winders or web pull rolls can advantageously be set in
an automated manner.
[0033] It is also advantageous for this reason if the device for
controlling and/or regulating the material web processing machine
comprises a Motion Control Unit and/or a PLC unit, which are able
to interpret and parse the material web processing-specific
parameter data electronically.
[0034] This material web processing-specific parameter data can,
for example, contain information relating to a modulus of
elasticity of a material web. By means of this information, it is
advantageously possible in particular to set controller parameters
of material web draw controllers or winders having a force
transducer or sensor-less winders, and to predefine a winding
hardness characteristic curve of a winder and/or to predefine a
lead to set web pull rolls. With regard to the modulus of
elasticity, information with respect to the material web width, the
material web thickness or the grammage and the material web
material, for example, is also contained indirectly. To this
extent, controller parameters of web draw controllers or winding
controllers can advantageously be set as a function of the modulus
of elasticity.
[0035] Furthermore, the material web processing-specific parameter
data can also contain, for example, information relating to a mass
and/or a diameter of a full roll or an empty core, it being
possible for this information to be used well for acceleration
feedforward control, diameter-dependent Kp adaptation of speed
regulators of the winding drive and/or for setting starting values
after roll changes (preset values) or limiting values during
winding, for example with respect to a diameter at which a roll
change is initiated.
[0036] To this extent, a particularly advantageous method variant
provides for the material web processing-specific parameter data to
be provided generally on the electronic data interface device as
digital job workflow data and specifically as digital print job
workflow data from a digital pre-press apparatus, in order to be
able to set the material web processing machine by using the
digital print job workflow data.
[0037] In the sense of the disclosure, the material web
processing-specific parameter data that can be used for the
material web processing machine or in particular for the device for
controlling and/or regulating the material web processing machine
can either be contained directly in the digital job or print job
workflow data as corresponding digital pre-press data or at least
determined indirectly therefrom.
[0038] With the present disclosure, use is advantageously made in
particular of the fact that data or pre-press data from a digital
pre-press apparatus is already part of a digital print job workflow
for processing printing jobs.
[0039] For example, digital pre-press stage data in this regard or
digital pre-press data comprises CIP4 data. This CIP4 data also
includes JDF data (JDF: Job Definition Format), it also
advantageously being possible for PPF data (PPF: Print Production
Format) to be embedded in the JDF data.
[0040] To this extent, the material web processing-specific
parameter data or digital print job workflow data can
advantageously be provided as CIP4-JDF data from media resources
belonging to a resource pool, the following data advantageously
being used in the JDF media resources: CoreWeight, Dimension,
Grade, MediaType, MediaTypeDetails, OuterCoreDiameter,
RollDiameter, Thickness; Weight and ResourceWeight. Cumulatively,
CIP4-JDF data of the Node-Info-Resources type with data relating to
FirstStart, LastStart and LastEnd can be used.
[0041] Furthermore, the material web processing-specific parameter
data or digital print job workflow data can also advantageously be
provided as CIP5-PPF data from Administration-Data, the following
data advantageously being used in the PPF Administration-Data:
CIP3AdmPrintVolume, CIP3AdmFilmType, CIP3AdmPaperGrade,
CIP3AdmPaperGrammage, CIP3AdmPaperThickness, CIP3AdmReelWidth,
CIP3AdmCylinderCircumference.
[0042] Furthermore, the material web processing-specific parameter
data or digital print job workflow data can likewise advantageously
be provided as Private-Data from JDF data or PPF data. Additional
data or information which, in particular, can be relevant for a
good material web run on the material web processing machine, can
be contained in Private-Data fields.
[0043] For example, statements with respect to a modulus of
elasticity of the material web, for example for controller
settings, with respect to a density of a roll, for example in the
unit "mass per unit volume" for acceleration feedforward control,
with respect to duration of the production, for example for
optimal-energy pre-definition of production speed and/or with
respect to a web length between individual printing units can be
contained there, it being possible for statements with regard to
the latter normally to be added only after defining the material
web processing machine used, for example by a JDF Agent.
[0044] Furthermore, the material web processing-specific parameter
data can advantageously cumulatively also contain dancer position
controller parameters (Kp, Tn, . . . ), which are predefined by
using the roll diameter. For this purpose, PPF pre-press data
"CIP3AdmCylinderCircumference" or JDF pre-press data "RollDiameter"
can advantageously be used.
[0045] To this extent, a further advantageous method variant
provides for such dancer position controller parameters to be
predefined by using the roll diameter.
[0046] Furthermore, the diameter-computer starting value can
advantageously also be predefined by using the roll diameter, it
advantageously being possible for JDF pre-press data "RollDiameter"
to be used for this purpose.
[0047] A roll change time can advantageously be predefined by using
the diameter of empty cores, it advantageously being possible for
JDF pre-press data "OuterCoreDiameter and Thickness" to be used for
this purpose.
[0048] It is further extraordinarily advantageous if different
pinole positions of a roll changer are preset by using the width of
the roll. To this end, PPF pre-press data "CIP3AdmReelWidth" or JDF
pre-press data "Dimension" is advantageously used.
[0049] Acceleration feedforward control and Kp adaptation of a
speed controller of a roll shaft can additionally advantageously be
predefined by using the diameter and the mass of the roll. To this
end, the PPF pre-press data "Cip3AdmFilmType, CIP3AdmPaperGrade,
CIP3AdmPaperGrammage, CIP3AdmPaperThickness and CIP3AdmReelWidth"
or the JDF pre-press data "CoreWeight, Dimension, Grade, MediaType,
MediaTypeDetails, OuterCoreDiameter, RollDiameter, Thickness,
Weight and ResourceWeight" can advantageously be used.
[0050] Controller parameters of web draw controllers or winding
controllers that depend on modulus of elasticity can advantageously
be set by using the width of the material web, the grammage or the
thickness of the material web and by using the material web type,
such as paper type, film or the like. PPF pre-press data used for
this purpose can be, for example, "CIP3AdmFilmType,
CIP3AdmPaperGrade, CIP3AdmPaperGrammage, CIP3AdmPaperThickness,
CIP3AdmReelWidth and/or CIP3AdmCylinderCircumference". Suitable JDF
pre-press data is, for example, "Dimension, Grade, MediaType,
MediaTypeDetails, Thickness and/or Weight".
[0051] For the reasons cited above, it is particularly advantageous
with regard to the present method if Private-Data such as modulus
of elasticity, density of the roll, the duration of production and
the material web length between the individual printing units of
the present material web processing machine is defined and
processed.
[0052] Furthermore, it is advantageous if the number of products
produced or material webs processed can be determined automatically
by the machine control system. If a product quality monitoring
device is contained in the present machine control systems, for
example in the Motion Control Unit, which differentiates the
products or the material webs to be processed into good or poor
products during the printing process (inline), the good products
can in particular be determined automatically by the Motion Control
Unit and, with the knowledge of the necessary number of products,
the material web processing machine can be stopped in an automated
manner in order thus to be able to utilize resources for example
with regard to material webs, ink, time period or the like
optimally. PPF pre-press data or JDF pre-press data that can
advantageously be used for this purpose can be, for example,
"CIP3AdmPrintVolume" or "DropItemIntent->Amount".
[0053] Moreover, an optimal production speed can be determined by
using a permitted production period. It is generally known from the
prior art that production of products on appropriate production
machines virtually always has an optimal-energy production speed.
In this regard, for example, energy consumptions of the present
material web processing machine, a maximum permissible production
period, an earliest or latest production start, a latest production
end and structural machine characteristics, such as a minimum
process speed or process speeds to be avoided, etc, can be
important boundary conditions for determining the optimal-energy
production speed. By using this knowledge, in the present case by
means of an appropriate machine control system, for example a
Motion Control Unit, the optimal machine speed can advantageously
be determined in an automated manner. Alternatively, this can also
be done by a job control system (Agent, MIS system (print job
management system) or the like). The JDF pre-press data used here
can in particular be "FirstStart", "LastStart" and/or
"LastEnd".
[0054] In general, there exists pre-press data which is present
both in the JDF pre-press data and in the PPF pre-press data. In
principle, the present pre-press data in existing data fields is
optional, which means that it does not have to be present or can
also even be present redundantly, i.e. duplicated. Here, for
example, rules for the use of the data can apply. For example,
rules which the JDF pre-press data are preferably to use can be set
up. However, if the necessary pre-press data or material web
processing-specific parameter data is not contained in the JDF
pre-press data, then use is made of corresponding digital pre-press
data from the PPF pre-press data. As a result of using both sets of
pre-press data, optional pre-press data which is not present in a
pre-press database can be used from the other pre-press database.
In this way, a certain redundancy is obtained, which advantageously
increases the probability of the presence of usable pre-press
data.
[0055] It is therefore particularly advantageous if the digital
print job workflow data is provided in the JDF data format and/or
in the PPF data format.
[0056] It is also particularly advantageous that such digital print
job workflow data can be provided online and thus also sent to
different print shops if the print job workflow data is created
centrally. By this means, it can advantageously be ensured that the
individual jobs in the different print shops are always processed
with the same process parameters, which means that the production
quality can be increased further.
[0057] To this extent, a further extraordinarily advantageous
method variant provides for digital print job workflow data from at
least one press stage apparatus to be provided electronically or
digitally on more than one material web processing machine equipped
with an electronic data interface device.
[0058] In particular in this connection, a further advantageous
method variant provides for the material web processing-specific
parameter data to be provided electronically online on the
electronic data interface device in an automated manner via a LAN
and/or WLAN connecting device.
[0059] By means of an electronic data interface device, the
material web processing-specific parameter data can advantageously
be fed online, for example directly into a device for controlling
and/or regulating the material web processing machine, so that an
error rate in handling the parameter data can be reduced further.
In this way, too, the production quality can be raised further.
[0060] It goes without saying that the present electronic data
interface device can be present in a flexible form as hardware
and/or as software.
[0061] Material web processing-specific parameter data incorporated
into digital print job workflow data can advantageously be
processed automatically by the device for controlling and/or
regulating the material web processing machine if the apparatus has
a parsing device for the electronic determination of material web
processing-specific parameter data.
[0062] If a parsing device for examining the pre-press data, for
example an XML parser for JDF pre-press data or PostScript parser
for PPF pre-press data, is implemented in the machine control
system, for example in the Motion Control Unit or PLC unit, an
entire JDF file or only relevant parts thereof (XML part-tree of
the "Media Resources" from the Resource Pool) or an entire PPF file
or a slimmed-down part of the file (e.g. reduced by image data) can
be loaded into the machine control system, for example via
FTP/TFTP, in a manner that is particularly simple in process
engineering terms. This means that no individual new data format or
transmission protocol for the transmission of the
production-dependent data from the print job management system, MIS
system in brief, advantageously has to be defined and implemented
in the machine control system.
[0063] To this extent, it is advantageous if the apparatus has a
parsing device for electronically reading the material web
processing-specific parameter data from digital job workflow data
or from digital print job workflow data.
[0064] A method variant that is advantageous in this respect
provides for the material web processing-specific parameter data to
be extracted from a digital JDF data format and/or from a digital
PPF data format by means of a parsing device.
[0065] Advantageously, the parsing device can be implemented in the
device for controlling and/or regulating the material web
processing machine.
[0066] Although, in the present case, reference has primarily been
made to printing presses, the disclosure is not restricted thereto
but instead relates to all types of processing machines in which a
product web or material web is processed, as already explained at
the beginning. With respect to printing presses, the method
according to the disclosure can be used very well in particular
with regard to newspaper presses, commercial presses, gravure
presses, packaging presses or presses for documents of value, as
likewise already described at the beginning. However, the method
according to the disclosure can advantageously also be used in
processing machines such as bag-making machines, envelope-making
machines, packaging machines or the like.
[0067] To this extent, the object of the disclosure is also
achieved by an arrangement comprising an apparatus for processing a
material web with a material web processing machine and a digital
press stage apparatus, which generates and uses digital print job
workflow data for processing the material web, the apparatus for
processing the material web and the digital press stage apparatus
being connected electronically to each other by means of an
electronic data interface device in order, by means of the digital
print job workflow data, to provide material web
processing-specific parameter data electronically to the apparatus
for processing the material web.
[0068] Advantageously, data or information with regard to material
web processing-specific parameter data that is already present in
the digital pre-press stage can immediately also be provided on
line to a material web processing machine or in particular a
printing press processing the material web further, and thus used
directly.
BRIEF DESCRIPTION OF THE DRAWING
[0069] Further advantages, objects and characteristics of the
present disclosure will be explained by using the appended drawing
and the following description, in which an apparatus having a
printing press for printing material webs and having an electronic
data interface device for receiving digital print job workflow data
from a digital pre-press apparatus is illustrated and described by
way of example. In the drawing, the single
[0070] FIGURE shows, schematically, a view of an apparatus having a
printing press for printing a material web and having an electronic
data interface device for receiving digital print job workflow data
from a digital pre-press apparatus.
DETAILED DESCRIPTION
[0071] The apparatus 1, shown in the single FIGURE, for processing
a material web 2 has a material web processing machine 3, by means
of which the material web 2 can be printed by a multiplicity of
printing units 4 (numbered here merely by way of example). To this
extent, the material web processing machine 3 in this exemplary
embodiment is a printing press 5.
[0072] The apparatus 1 also has a machine control system 6 having a
device 7 for controlling and/or regulating the material processing
machine 3. The device 7 for controlling and/or regulating the
material processing machine 3 is in turn distinguished in
particular by a Motion Control Unit 8 and a PLC unit 9.
[0073] According to the disclosure, the apparatus 1 is equipped
with an electronic data interface device 10, in order to receive
digital print job workflow data 11 from a digital pre-press
apparatus 12 electronically. Here, the electronic data interface
device 10 is operatively connected to the digital pre-press
apparatus 12 online via a LAN connecting device 13 and via the
Internet 14.
[0074] The digital print job workflow data 11 comprises, as digital
pre-press data 19, inter alia, material web processing-specific
parameter data 20 in the JDF data format and in the PPF data
format, by using which the material processing machine 3 can be
set.
[0075] In order to be able to extract the material web
processing-specific parameter data 20 from the digital print job
workflow data 11, the controlling and/or regulating device 7
advantageously has a suitable parsing device 25.
[0076] The material web 2 is led through the material web
processing machine 3 in the transport direction 30. Here, the
material web 2 is unwound from an unwinding roll device 31 on the
inlet side 32 of the apparatus 1, led through the material web
processing machine 3 for printing or the like and wound up again,
finally processed, on a winding roll device 33 on the outlet side
34 of the apparatus 1. As an alternative to the winding roll device
33, a cross-cutting device with a stack output device, not shown
here, can advantageously also be provided.
[0077] For the purpose of optimal treatment of the material web 2,
the unwinding roll device 31 is assigned dancer elements 35
(numbered here merely by way of example), and the winding roll
device 33 is assigned a force transducer element 36.
[0078] Located in between on the inlet side 32 is a clamping point
37 having a drive roll 38 and a pressure roll 39, it being possible
for the drive roll 38 to be driven by means of a drive motor 40. A
speed of revolution and an angular position at the first clamping
point 37 are measured by means of a rotary encoder 41.
[0079] In a corresponding way, on the outlet side 34 there is a
further clamping point 42 having a further drive roll 43 and a
further pressure roll 44, it being possible for the further drive
roll 43 to be driven by means of a further drive motor 45. A speed
of revolution and an angular position at the further clamping point
42 are measured by means of a further rotary encoder 46.
[0080] The actual value of the material web tension between the
unwinding roll device 31 and the winding roll device 33 is
determined by means of a measured value transmitter 47, the
material web 2 being led in over a first deflection roll 48 and led
away again over a second deflection roll 49, in order then to be
able to run into the printing units 4.
[0081] In particular, the above-described components 4, 31, 33, 35,
36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46 and 47 of the material
web processing machine 3 and the apparatus 1 are in operative
contact by means of data lines 50 (numbered here merely by way of
example) shown by way of example, with the device 7 for controlling
and/or regulating the material processing machine 3, so that the
latter can also be set optimally or controlled and/or regulated
online by means of the material web processing-specific parameter
data 20 extracted from the digital print job workflow data 11 by
means of the parsing device 25.
[0082] For this purpose, the digital print job workflow data 11,
which is present here in the JDF data format and in the PPF data
format, is transmitted electronically from the digital pre-press
apparatus 12 via the Internet 14--or else via another electronic
route--to the electronic data interface device 10. There, the
digital print job workflow data 11 present is read in an automated
manner, via the parsing device 25, into the device 7 for
controlling and/or regulating the material web processing machine
3. In particular, from the material web processing-specific
parameter data 20 provided here, the Motion Control Unit 8 and/or
the PLC unit 9 calculate the optimal material web processing
machine parameters characterizing the web run, for example for the
winding process and/or for the material web draw control, as a
function of the material web 2 to be processed. The production is
then started without any manual input of this material web
processing-specific parameter data 20. The end of the production
can advantageously be carried out in an automated manner, likewise
via JDF/PPF data. Likewise, a new job can be started by reading in
new JDF/PPF data.
[0083] It goes without saying that the exemplary embodiment
explained above is merely a first configuration of the apparatus 1
for carrying out the method according to the disclosure. To this
extent, the configuration of the disclosure is not restricted to
this exemplary embodiment.
[0084] All the features disclosed in the application documents are
claimed as fundamental to the disclosure if they are novel with
respect to the prior art, individually or in combination.
