The
production department of any modern printing company can not
rely on a new printing press with a high capacity. It needs to rely on a
complete printing standard process to achieve seamless production and
monitoring.
1.
Familiar with the essence of German industry 4.0
The
essence of Deutsche Industries 4.0 is to collect as much as possible all the
important "things" inside the plant and the Internet connection, so
that management real-time knowledge of the plant's main data information. Specific
to the printing industry, is to try to remote and real-time control of the way,
effective monitoring, recording the operation of each group of printing presses
to ensure that its product quality and productivity can meet the objectives and
requirements.
The
real possession of advanced equipment and technology, and to standardize the
operation of the printing process less than 10% of market share. The
fact that these factories can be used without manual finishing can make use of
the intranet so that management can always monitor the operation of each group
of printing plant is very few. Most of the factories still need to
rely on the captain of each press to print the performance of each work order
into a report, or QC staff at the scene to take each copy of the operation of
the press report to the relevant departments for review. These methods not only
rely on manpower, the report is lagging behind, once the report found that the
printing quality is not up to the standard, will lose the "disease to
shallow TCM" time.

Implement real-time monitoring solution
Printing factory managers, as long as a
little attention will find that printing equipment, especially testing and
management software in the past five or six years has improved a lot, the price
also increased due to increased sales and gradually reduced. Just configure the
automatic spectral density scanner and scoring and detection software can be
the essence of the German industrial 4.0 to play most vividly. Automatic
spectral density scanner - to measure the height of the color block is less
than 3.5mm is better, otherwise a waste of paper. Scanning speed of about 10
seconds to complete the measurement of a piece of more than 200 pieces of color
off the print.
Scoring
and inspection software - this type of software can connect and drive automatic
or manual optical density scanner, in each scan can be printed immediately
after the score to show whether the printed piece with the buyer or factory-set
custom standard. If it is found that the print is not up
to standard, the software will display the real-time reasons for non-compliance
and give corrections instructions. Installation of such software can reduce the
degree of dependence on technicians to ensure product quality and increase
productivity.
If
each press is equipped with the appropriate scoring and inspection software and
an automated spectro-density scanner, a central server can be built to monitor
each press in real-time and captain's performance, especially for installations
in an outward- Factory interior to ensure consistency of print quality.
Configuration
of the above equipment and software, can be considered to install online
automatic ink control software. The main functions are:
A)
pre-ink function - the ink required for each work order to CTP version of the
ink range as the basis for calculating the amount of ink, the amount of ink
required in advance of the command transmission to the printer's ink key
console, so that The initial amount of ink before printing is close to the
amount of ink actually printed, reducing the commissioning time for each work
order.
B)
Closed-loop system - During commissioning and printing, each time a scanner
detects a print and discrepancies between the print quality and the target
value, the closed-loop system outputs an instruction to adjust the ink key to
the desired target value.
It
should be noted that the printing press, especially its ink key parts need to
be maintained in place, and the whole plant must also be standardized to
operate, otherwise it is not easy to achieve the desired results.
