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. Roll to sheet 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 S peed Master SM102 that can print on both sides and apply water-based gloss. 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 on the 5th 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 LITHRONE S40 that can print on special printing materials such as vapor-deposited paper, transparent raw materials, biochemical paper, etc. 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.
