Heidelberg and WST Systemtechnik offer joint solution
One particular highlight of the newly developed Prinect Signa
Station Version 1.5 is its capacity to dynamically generate
barcodes which can be used to prevent errors when collating and
folding sheets in postpress. The Prinect Signa Station provides
these barcodes with the necessary data. Special barcode readers
from WST Systemtechnik GmbH (WST) record and check the codes in
postpress.
"This solution developed jointly by Heidelberg and WST
will enable printshops to significantly increase their postpress
efficiency. At the same time they could improve customer loyalty
since it will prevent errors which the customer often only
discovers when using the finished product," explains Dr. Peter
Leu, Vice President Prinect Product Management at Heidelberg when
asked about the advantages of barcode generation within the Prinect
Signa Station.
Barcodes boost transparency and improve production reliability
The use of barcodes is continually growing as
requirements on print product quality become ever tougher.
Commercial printers too are applying barcodes to the print sheets
fed into their saddlestitchers, folders or collating machines in
order to ensure unique sheet assignment and to identify missing
sheets at an early stage. Special barcode readers from WST record
and check each sheet in real time in postpress. Prinect Signa
Station independently generates the necessary barcodes directly in
the system, deriving them dynamically from the user specifications.
If one of the specifications changes for a sheet, the information
in the barcode changes automatically.
The Prinect Signa Station defines the barcodes from the data
for the print job with variables such as the job number, customer
number and folding sheet number. The user can enter the information
manually into the Prinect Signa Station or adopt it via JDF from an
MIS system using the Prinect Printready System.
Just like any other print control mark, the barcode can be
positioned at any point on the print sheet or folding sheet. Should
the user position it on the plate template, errors in further
production can be all but excluded. In this case, there is no need
for the barcode to be positioned manually. Since it adjusts itself
dynamically based on the job information already stored in the
Prinect Signa Station, the operator has no need to concern himself
with these aspects.
Link to the WST system
WST's OBC (Opto Barcode Control) barcode system
identifies a machine-readable mark which is integrated into the
waste part of the print product. This marking system is not
specific to WST, rather the industry standard barcode (Code 2/5
Inter-leaved) is used which makes implementation and
standardization in prepress much easier. The barcode readers
developed by WST record the printed marks which are at least two
millimeters in height.
Code reconstruction for different sheet orientations
The barcode system from WST not only monitors the entire
area in which the code is theoretically located, but is able for
the first time to reliably reconstruct the code - which sometimes
travels through in different orientations - from its fragments.
Installation and integration
Only a small number of easy-to-fit parts are required to
equip the machines in postpress. Each station of the collating or
folding machine is provided with a barcode reading head. WST
supplies the special mount. A maximum of 4 reading heads are linked
to a station computer which processes and evaluates the data that
has been read. These station computers are located inside the
machine. A standard industrial PC manages the data and controls
communication within the network. There is only one operating
button. WST's OBC 4-60 system can be integrated into any
postpress machine with between 4 and 60 stations. It also offers
the option of recording and statistically evaluating jobs.
Prospective clients for the system should contact their
regional Heidelberg sales office. Concerning the barcode readers
they could also contact WST Systemtechnik GmbH.
