    Digital printing presses have been actively developed recently, but offset printing still leads in terms of new equipment and production. Regarding the use of offset printing presses in recent years, power-saving UV, LED-UV, and inline print quality management systems-such as quality inspections, automatic registration, and color control-have increased rapidly. These systems reduce printing loss, time loss, and delivery time; further, they increase the production efficiency of offset printing. Therefore, the retrofit of those systems to existing machines is increasing. Gang-run printing that executes multiple work projects simultaneously raises the profitability and competitiveness for short-run offset printing. It is expected that automatic operation by nonstop startup and optimized operation by IoT will be realized soon. The integration of offset printing and digital printing in workflow and production systems is becoming more necessary.

    Ninety percent of drupa 2016, or digital drupa, involved digital presses. One year has passed, and trends in the capital expenditures of medium-sized printing companies in Japan indicate that they are not adopting digital technologies; on the contrary, they prefer modern offset presses, which offer a better short-run ability and superior profitability. Moreover, there is a powerful offset printing supply chain in Japan. Now, it looks as if our digitalization will be postponed to some extent. Furthermore, our traditional print culture with paper posting of ads gives a stronger ROI than direct mail, and there is a great affinity for digitalization.

    A printing company has reported a recent trend in which the number of copies per job order is less than in the past, though the variety of jobs has increased considerably. The background for this scenario includes the diversification of consumers, shorter lifecycles of printed material, and the spread of online media. There are two major digital print technologies: electrophotography and inkjet. This paper describes conventional printing technologies and the latest in digital printing, with a focus on inkjet technology. The aim is to promote an understanding of the features of each, along with their strong and weak points. Additionally, we discuss how to attain efficient advances in printing for businesses, how to approach the customer, and how to use various printing technologies for business purposes.

    Gravure printing has the advantages of high productivity, compatibility with a wide variety of materials, and high print quality; it is used mainly for flexible packaging markets domestically and internationally. However, the flexible packaging industry must make changes for greater product convenience, a declining workforce, and the necessary reduction of volatile organic compounds (VOCs) for environmental sustainability. Digital printing for flexible film has improved rapidly. Combining digital printing (inkjet printing) and the existing analog printing (gravure printing) has the advantage of improving the efficiency of production. In this paper, to realize a sustainable society, we describe the water-based inkjet printer "FXIJ," automated laser gravure cylinder production with the "NewFX3," and newly water-based pigment inkjet ink with non-reactive, non-hazardous, and odorless materials. These innovations support the proposal for a new production method (seamless printing) for the flexible packaging market.

    Most color specifications for printing are specified as ISO 12647 by ISO⁄TC 130. Recently, TS15331 has been discussed in relation to TC 130 as a future ISO standard. The Japan Color Digital Printing Certification was established by the Japan Printing Machinery Association (JPMA) in May. In Europe, Fogra is the leading Process Standard Offset (PSO) and Process Standard Digital (PSD). In the USA, IDEAlliance promotes the G7 Certification for both analog and digital printing. This article explains these certification programs and the new trend in ISO standards, including ISO⁄PDF 2.0.
