Attention technology of printing engineering

With the short delivery time required by the printing market, and the progress of small batches, the competition tends to intensify, and it is difficult to stop low prices. Therefore, in order to respond to the evolution of the market environment, printing companies intend to establish a production system that aims at thorough rationalization. At the same time, there are also issues that need to be considered in the production of environmental protection needs. In view of this, it is tentative to select several technologies that are worthy of attention in print production engineering.

Unique ink fountain device

At the International Printing Equipment Exhibition held in Japan in 2005, a unique ink fountain that can be mounted on a printing press ink supply device emerged. Although its ink fountain roller key is fixed, but its ink transfer roller is divided. The individual ink rollers separated by the outside are driven by air pressure to contact the ink fountain roller, and the ink supply amount is adjusted according to the contact width thereof.

There is special software for ink control, which can simultaneously fine-adjust the data of printing patterns and ink supply. In addition, the cleaning of the ink fountain is also very simple. The entire ink fountain is covered with a roll of film like a polyethylene wrapper. When the ink fountain is washed, the inked film is scraped with a squeegee and then rolled. The film on the take-up device can be replaced.

Such devices can be installed on machinery such as sheetfed printers, brand printers, beverage can printers, commercial form printers, and the like. In this way, the ink supply can be stabilized, waste pages in the printing process can be reduced, and the working efficiency can be improved.

Roll to sheet related to cost savings

In a paper feed location of a sheet-fed printing press, a device that can use a web to feed a printing press. This is a structure in which the paper is cut in a set size using a paper cutter, and the paper is fed in a single page state. Originally developed by Europe and the United States, the background of its development is that Europe and the United States do not have a logistics system that can simply provide various kinds of paper unlike Japan. The main reason is to reduce waste and the failure of the corresponding paper feeding device in terms of cost. Any evaluation made by the imported printing companies is capable of reasonably cutting paper.

The greater the number of jobs in this kind of device for large-volume jobs or using the same size of paper, can save costs and improve productivity. At the same time, it does not require time for stacking papers, and the operating efficiency naturally increases.

It is expected to develop new business waterborne brightening oil

Heidelberg Japan provided a 10-color printing press, Speed ​​Master SM102, which runs on paper and double sided and can be coated with water-based lacquer. In principle, water-based gloss oils belong to alcohols and are not considered to be compatible with oil-based inks, but the application of water-based gloss oils is regarded as a highly imaginary problem. Europe has long had materials suitable for this method, which Japan did not have in the past. Recently, ink manufacturers have developed a new type of water-based bright oil that can be applied to oil-based inks with water-based gloss oil and dried by IR.

The structure is to remove the blanket automatic washing device when the water-based bright oil needs to be applied, and replace the water-based bright oil coating device. Then in the 5th
IR drying was performed at the delivery position after the drum and the 10th drum.

This two-sided, one-pass, water-based gloss print reduces bruising and soils the printed surface. Its greatest advantage is that it can be used to carry out new business projects by using low cost and shortening the drying time compared with the use of UV inks.

The printing function of special raw materials expands business activities

Komori Printing Machinery Co., Ltd. has provided a printer Lithrone S40 that can print on special substrates such as vapor deposition paper, transparent raw materials, and biochemical paper.

Since the usual oily inks take time to dry, most of the special substrates are printed using UV inks. When UV ink is used, the configuration of the printer is also different from the case of using oil ink. Need UV-specific version, ink roller, ink cleaning solution, UV lamp and so on. As for the printing of special printing materials, emulsification is easily caused due to the poor absorption of ink and dampening solution. Therefore, efforts must be made on the water supply device. Once the printing companies hold this special structure of the printing press, the scope of business activities can be extended to get rid of the price competition.
