With the short delivery time required by the printing market, the progress of small batches, and the intensification of competition, it is difficult to stop low prices. Therefore, in order to cope with the evolution of the market environment, printing companies intend to establish a production system aimed at thorough rationalization. At the same time, there is also the issue that the awareness of the need to protect the environment must be included in production. In view of this, let me choose a few technologies that deserve priority attention in the printing production engineering.
Unique ink fountain device
At the International Printing Equipment Exhibition held in Japan in 2005, a unique ink fountain appeared that could be attached to the ink supply of the printing press. Although the key of its ink fountain roller is fixed, its ink transfer roller is divided. The individual divided ink rollers are driven by air pressure to contact the ink fountain roller, and the ink supply amount is adjusted according to the contact width.
There is a dedicated software for ink control, which can fine-tune the pattern and ink supply data at the same time. In addition, the cleaning of the ink fountain is also very simple. Use a roll of film similar to polyethylene wrapping paper to cover the entire ink fountain. When cleaning the ink fountain, scrape the film with ink on the ink scraper, and then roll it in The film on the take-up device can be replaced.
This device can be installed on machines such as sheet-fed printers, trademark printers, beverage can printers, commercial form printers, and the like. In this way, the ink supply can be stabilized, and the waste pages in the printing process can be reduced, thereby improving work efficiency.
Rolltosheet related to cost reduction
In the paper feeding position of the sheet-fed printing machine, a device for feeding paper from the Roll Paper to the printing machine can be used. This is a structure in which a paper cutter is used to cut to a set size and the paper is continued in a single-page state. Originally developed in Europe and America, the background of its development is that Europe and the United States do not have a logistics system that can easily provide various papers like Japan, mainly because of the cost reduction and the failure of the corresponding paper feeding device. All the evaluations made by the imported printing companies can reasonably cut the paper.
This device can save costs and increase productivity for more jobs in large batches or using paper of the same specification, and at the same time do not spend time on stacking paper, the operation efficiency is naturally improved.
Water-based bright oil expected to expand into new business
Heidelberg Japan provides a 10-color printing machine Speed ​​Master SM102 that can print on both sides and apply water-based bright oil. In principle, water-based bright oils are alcohols, and they are not considered to be compatible with oil-based inks, but the application of water-based bright oils is considered to be a highly imaginable subject. Europe already has materials suitable for this method, which Japan did not have in the past. Recently, ink manufacturers have developed new water-based bright oils that can be applied to oil-based inks and dried by IR.
The structure is that when the water-based bright oil needs to be applied, the rubber cloth automatic cleaning device is removed, and the water-based bright oil coating device is replaced. Then, IR drying is carried out at the paper receiving portion after the fifth roller and the tenth roller.
This water-based bright oil printing with two-sided paper feeding can reduce bruising and staining the printing surface. Its biggest advantage is that compared with the use of UV inks, it can adapt to short delivery times at low cost and shorten the drying time. It is expected to use this to start new business projects.
The printing function of special raw materials expands business activities
Komori Printing Machinery Co., Ltd. has provided a printing machine LITHRONES40 that can print on special printing materials such as vapor-deposited paper, transparent raw materials, biochemical paper, etc., which attracts attention.
Normal oil-based inks use UV inks to print for special printing materials because it takes time to dry. When UV ink is used, the configuration of the printing press is also different from the case where oil-based ink is used. UV-specific plates, ink rollers, ink cleaning solution, UV lamps, etc. are required. As for the printing of special printing materials, emulsification is easily caused due to poor absorption of ink and fountain solution, so efforts should also be made on the water supply device. Once the printing company holds this special structure of the printing machine, the scope of business activities can be extended, which can get rid of the troubles of price competition.
Printed product inspection device for improving speed and accuracy
This inspection device relies on the camera or the light source to compare the read data with the originally registered correct data, so as to detect the scratches and stains on the printed product, as well as the inaccurate registration. At the 2005 International Printing Exhibition, more accurate and faster devices were introduced than before. Generally, it is used to inspect the surface of printed products, especially for printing companies that require strict inspection of pharmaceutical packaging. Today, most printing companies still use visual inspection to check, but it is ultimately limited, depending on physical conditions will also affect accuracy. In view of this, inspection operations that rely on human-sea tactics will ultimately be converted to rely on machinery.
Promisingly individually driven sheetfed printing press
At present, the automation of printing presses has reached the point of being automatically preset, which greatly reduces the burden on operators, and there have been enterprises equipped with women equipped on rotary machines. Individual drive generally refers to innovations in offset printing presses. The original printing machine was always driven by the whole machine as a whole, and the single drive was a special motor that could drive a certain cylinder alone. This is designed with the goal of improving the working efficiency of replacing printing plates. In the past, when replacing printing plates, they were always replaced one by one, and the increase in the number of colors would take more time to change plates. Nowadays, it is changed to the plate cylinder which can be driven separately, and the plate change of all cylinders can be completed at once.
According to different machines, there may be some differences. Any printing company that introduces this innovative method has achieved time savings in plate change and reduced the burden on operators. In the future, we are looking forward to the popularization of sheet-fed presses that are driven separately.
Endless environmental issues
Regardless of the ISO management system, as a means of responding to environmental requirements, the non-processing type printing plate can be admired to customers. Speaking of the printing plate corresponding to the environment, the first is the horizontal version. Because it uses butterflies as its logo, customers are currently very concerned about butterfly trademarks. In Japan, about 130 companies have joined the Japan Horizontal Printing Association (JWPA).
After the exposure of the non-horizontal plate, the silicon layer exposed by the pretreatment liquid is swelled, and the part is scraped off with a brush. To improve visibility, the image part is dyed and washed with water. Because it does not appear waste liquid, it is recognized as an environmentally friendly method. Now it has become a model of no treatment, which has attracted the attention of the industry.
