At present, offset printing is the mainstream technique used for newspaper printing. Because the number of copies, colors, and pages has increased, machines have become physically large and automated; hence, their operation requires fewer people than before. To further improve the efficiency of these machines and to pay attention to the additional value print, it is necessary to collaborate with industries in other fields. Although the coexistence of printing with paper is indispensable, printing companies will also produce an Internet version.

In about 30 years from now, newspaper presses will have changed to offset printing from letterpress printing. The development main subjects of the newspaper presses was improvement in the speed and quality up to the present. Now, newspaper publishing companies are facing difficult circumstances due to the business downturn. Therefore, these companies are demanding newspaper presses with high manufacturing efficiency. In this paper, the latest newspaper presses and control devices that were exhibited at JANPS 2009 are reported. These include "COLOR TOP ECOWIDE," "T-CUTTER," and "GEMINUS" as well as the digital printing system "JETLEADER," developed by Tokyo Kikai Seisakusho (TKS).

Newsprint has followed the dramatic change and great evolution in printing technologies until now. In this review, the technological innovations in newsprint in the time spans of 1945-2000 and 2000-2010 have been discussed. The changes in materials (from domestic softwood pulp to recycled pulp), paper machines (extended wire width, high speed, and use of twin-wire paper machines), and the weight of paper (decrease of approximately 10 g⁄m² in the last 20 years) were few of the great technological innovations before 2000. After 2000, the development of surface coating agents (new sizing agent), neutral papermaking, and high compounding ratio of calcium carbonate were significant improvements in newsprint. New surface sizing agents were developed, and this made it possible to control the water absorption characteristics of newsprint. In addition to the trend toward lightweight materials, the increase in the number of color pages required a high level of printing. As a solution to this situation, neutral papermaking was advanced because this papermaking method allows the use of calcium carbonate, which has several favorable properties such as affordability, high opacity, high brightness, and a certain degree of ink absorption potential. The high compounding ratio of calcium carbonate was accompanied by many technical innovations such as the optimization of shape and physicality of calcium carbonate and improvements in the yield system, internal strength agent, external strength agent, and external sizing agent. Nippon Paper Industries Co., Ltd. developed a high-quality newsprint (ash content: 15%), which excels in print quality in comparison to the usual newsprint (ash content: 5-6%). We have all switched to this high-quality newsprint.

Recent trends in newspaper ink have been described from three viewpoints. First, the development of high-speed newspaper printing ink is required to adapt to newspaper printing sites (beneficial to newspaper printing press sites). Second, the development of such newspaper ink can provide high-quality newsprint that everyone will appreciate (beneficial to consumers). Third, the development of such a novel environment-friendly newspaper ink can contribute to environmental protection. Recent trends in newspaper ink are described from three points. First, the development of high-speed printing newspaper ink is required to adapt to newspaper printing sites (Contribute to the newspaper printing press sites). Second, the development of newspaper ink can provide high-quality newsprint everyone can identify (Contribute to consumers). The third, the development of new environmentally friendly newspaper ink can provide more advanced (Contribute to environmental protection).

We present a CTP (computer-to-plate) system that allows the direct production of printing plates by scanning high-directivity light, such as that from laser beams, at an extraordinary speed, resulting in the rapid digitization of prepress operations. Such rapid digitization has become the de facto standard in the newspaper print market, where a high throughput and high stability of the makeup system are required. As a result of the increasing market demand for CTP materials, high throughput, and low cost year after year, there are rising concerns about the deterioration of environmental quality. Further improvement is expected in the future. Our paper reports on the latest technological trends of printing plates in general.

Printing blankets and rubber rolls have been modified due to the changes in both the press and the materials used in it such as paper, ink, and wash material. The compressible layer in the blanket is improved for quick recovery from repetitive compression for high-speed presses. In "thermasphire technology, " a dry rubber sheet laminated on a base fabric is used as the compressible layer. This new technology gives stable quality and less gage loss. The latest technology uses a metal-backed blanket for 4 × 1 presses. The rubber roll has lighter weight because of the use of a carbon fiber reinforced plastic (CFRP) core. Also the rubber roll has been improved to less diameter shrinking and less heat build-up due to a special rubber compound. The use of oscillating rubber rolls reduces the rubber damage from the plate edge.

It is necessary to unite new ideas in present newspaper printing technology prior art so as to enable newspaper printing technology to dynamically adapt to the required quality standards and limitations in this day and age. There are three key steps to idea generation. (1) An all-company approach that integrates the operations at the print site with those in prepress. (2) Chance of study that acquires basic knowledge and technology that becomes base thought whether to be able to do something every day. (3) A mechanism to obtain consistent quality. The quality never improves if it is important that the print quality manage the analog by using digital, and the print engineer does not have the ambition. It is worth discussing the switching off of the rudder of newspaper print equipment, which is a process that will be followed in the industry in the near future, although it is forecast that a rotary inkjet printer called a print-on-demand (POD) press might also experience a surge in demand. However, this device might become obsolete if the preparation is not advanced now. the dream is requested to be connected to a severe current ambient surrounding, and only having the stuff of dreams lead to rapid improvement in newspaper quality.
