Short-cycle on-demand printing requires efficient post-press processing equipment, network-bound binding machines, folding machines and sewing machines are important manifestations of automated post-press equipment.
To meet the market requirements of on-demand printing, it is not only easier to install and easier to operate, but the corresponding post-press areas are not taken seriously, making them compatible with prepress and printing processes. Development will affect the overall printing efficiency.
The new mechanical requirements of the printing market require a mechanical design concept. The new mechanical concept requires changing the machine design pattern, improving the information technology, and connecting the sewing machine, the binding machine and the folding machine through the network: automatic assembly and control technology enables remote management This has been achieved, reducing the workload of the operators.
JDF came into being. JDF is a data transmission format for a terminal port and another terminal port, which has brought huge impact to the printing industry and has been generally accepted. Postpress equipment manufacturers are less active in CIP4 organizations than prepress equipment and printing equipment suppliers.
The concept of JDF is that a magazine, booklet, book or album can be preset in the machine during the production phase, which saves production time. The most important thing is that if all the parameters are set in advance, you no longer need to re-enter the value, you can avoid entering the wrong data information. The powerful functions and advantages of JDF in the postpress field are reflected in the following aspects.
Customers can keep track of production conditions through JDF
JDF is sweeping, developing, and dynamic information. It can centralize execution information and step information, and can find data from the control center at any time to provide customers with the information they need at any time. For example, production schedules for printed products, production planning and costing become more accurate. And the customer can always know the information he needs, so that the relationship between the printing company and the customer is closer.
However, to some extent, some of JDF's functions are not fully utilized in the field of post-press processing and other process networking. Different companies around the world are madly trying to add JDF design concepts in the design concepts of saddle stitching, paper cutters, and binding machines.
Among them, Scenic Software's UpFront software puts a key element in the JDF workflow, which can arrange how the products to be printed are printed on the machine, and how to get the full-page printing data information for the folding machine and the binding production line. The PPF (print production format) defined in the workflow for integrating upstream and downstream supply chains is also known as the "print production format".
The finishing line that is stored and set up by Amrys is an ideal choice for matching with JDF. When a printing company receives repetitive printing tasks such as magazines or books in a standard format, the system can effectively reduce preparation time. Especially in short-run printing, the gutter needs to be shut down frequently for preparation. This system can realize automatic fund accumulation. Ma Tiankun believes that in the transition of more than three tasks in each link, it can be considered that the payment of this facility is very worthwhile.
JDF application in digital printing
In the highly automated field of digital printing, there are often many different tasks to be done in an hour. Therefore, talking about paper waste between two print jobs is a common problem; especially in traditional post-press processing lines, it wastes more prints to get the final product.
How to reduce waste is a concern of many digital printing companies? The use of digital workflows is much less than the waste on traditional post-press lines, minimizing waste. Therefore, the traditional post-press processing functions of different machines are concentrated on one digital printing machine, making it possible to produce brochures, spiral bindings and even soft-faced bindings, which has become one of the urgent needs of the current market. It is also one of the most concerned issues for post-press equipment suppliers.
To break this traditional post-press production method, and to establish a new post-press production method requires a process; in particular, it is necessary to integrate the pre-press, printing, and post-press as a unified effective line. This means that digital presses require more than just sophisticated, professional digital printing equipment, and digital finishing equipment that can be paired with digital presses. Swiss manufacturer HUKELER has been a leader in this field in recent years and has been committed to providing customers with increasingly sophisticated system solutions that reflect the impact of digital products.
Before the advent of digital printing, there was almost no need to add automatic controls to the finishing system because of the long production cycle and the lack of power to drive post-press processing more efficiently. Because there are some natural errors in the production process of post-press processing, it is often necessary to use tools to make some minor adjustments to the post-press equipment, which is a waste of time. In order to improve production efficiency and meet market demand, digital printing, especially in personalized digital printing, guarantees the overall importance. Therefore, the use of automated devices instead of trial and error methods allows the operation to maintain very high accuracy at the beginning, which is very important for digital printing.
Developed the i2i program and made the CIP4 standard interface, so that any machine connected to the department can be controlled by a general console. Such a skilled operator can start the machine and monitor the overall production process of the print job, which can reduce a lot of loading and unloading work. In this way, only a skilled operator is required to control and operate all the production equipment, and the unskilled operator can perform some ordinary installation and unloading work, which greatly improves the printing efficiency and saves the printing cost.
JDF is more widely applicable
JDF usually represents a complete concept, such as a fully integrated finishing line, at the expense of a post-press process. Instead, JDF helps customers solve problems by providing a complete post-press solution.
Advanced post-press processing equipment has gradually replaced a large number of manual repetitive operations, which has brought about a dramatic development of productivity, which has also promoted the introduction of some post-press equipment by some printers. Increasing market demand requires automated post-press equipment because of the relatively large number of errors in manual operations. In particular, stackers, shrink wrappers, etc. need to reduce manual operations to reduce the number of employees in the workshop. The most important thing is that automated production equipment can ensure that products are delivered to the next production process in a timely manner.
Many vendors can only use one part of their workflow for their products, so they must interoperate with products from other companies.
The Prinect JDF workflow connects all the work and it can be quickly installed on the ST400 saddle stitcher and the Statl folder. For the paper cutter, if it can be connected to the Prinect network, the recommended solution is compucut - an unconnected console connected to the paper cutter and then connected to the Prinect and Prinance - MIS applications. These processes are carried out under the control of the postpress information system. The system server accesses the data needed for the next process, and the required settings are loaded at the same time. The waste of all work and the actual number of jobs will be fed back to the MIS for more accurate cost calculation and production control.
ST400 Riding King can provide a complete, accurate and complete production process. ST400 Riding King can start working in two minutes after receiving the data. The difference is not only in the effective reception of data, ST400 riding order Wang also made great progress in technical design. The Riding King ST400 uses a servo engine for moving position settings and can be driven directly, and digital control frees the saddle stapler from the constraints of the drive shaft. This technology is currently used in general, especially in the application of web presses, and other similar technologies can be applied as needed.
The Stahl folder has gradually adapted to this technology, and its servos can repair deformed plates and print thicker paper. The correctness of this concept has been explained, and Heidelberg has to extend this concept to other post-press systems.
Other thinking about this application is also very broad, and this number will continue to grow. This is just that you can find it when you need it. From the perspective of reducing waste, the operator can make a decision to produce only a single page, and the machine's response is very sensitive.
Obedience is the key
Obedience is the key to the future development of post-press processing technology. Obey the instructions of JDF and obey the short preparation time and zero waste requirements. Applying these postpress systems to digital printing and long-run commercial printing is not a problem, as the needs are the same.
