Japan’s first Waterless Eco-UV
Yoshida Printing Co., Ltd.
Yoshida Printing (CEO Yoshida Katsuya, based in the City of Kanazawa, Ishikawa Prefecture) is the first company to introduce the Waterless eco-UV printing. Waterless eco-UV printing is the integration of environmental action and high-quality of waterless printing, together with its quick drying and powderless characteristics of eco-UV, the new approach is meeting multi-lateral client needs.
The company was founded in 1906 and is carrying out promotions for print and digital content based on Kanazawa and Tokyo. The company has been applying the waterless printing since 1992. Regarding the reason for the application, Yoshida explained, "We have been seriously considering the environment for over 20 years. We apply the method as we adhere to environmentally-friendly approaches. The conventional printing method applies the dampening system, which generates waste water. Therefore, we wanted to introduce waterless printing no matter what.”
In 2002, the company joined the incorporated association “Japan Waterless Printing Association” (JWPA). Utilizing the association’s butterfly logo, the company provides high-quality prints and actively uses waterless printing. Currently, it maintains five waterless machines in its headquarters and three at the factory in Shiomi, Edo-ku, Tokyo.
The company had to replace sheetfed presses at some point. In conventional printing process, powder is used, which can easily cause printing issues. Additionally, orders with short deadlines increased, which required greater efficiency in printing and post-press. Therefore, the company chose a high sensitivity UV-type press that do not use powder and presumable improvements in productivity. At that time, there were few cases of waterless printing with high sensitivity UV-type presses and some thought that the application of waterless printing was unreliable.
However, the company applied waterless printing and introduced the B1 sized Mitsubishi DAIYAMOND V3000 LS-4. Waterless printing was conducted on a full scale using eco-UV.

Advantages of waterless UV printing
Higaki, the manager of the production department, explained the difference between waterless printing and waterless eco-UV printing. “There is no need to clean the blankets when printing on the backside as no spray is used. UV inks are not hardened without UV lamp; therefore, there are no hickeys to cause pin holes. As a result, productivity increases.”
He added, “This was the first time I used UV printing but I undertook the tasks with the attitude that ‘I would perform the printing as typical waterless printing.’ We handle ordinary, every-day problems such as blanket selection by communicating with ink manufacturers and currently, there are no issues.” He then commented on the effects since the introduction of UV printing. “When compared to normal waterless printing, productivity increased approximately 30 to 40%.”
Waterless UV printing is characterized by no dampening, no use of powder, a longer lifespan for machines, and faster operation time. Simply put, it maximizes the benefits of waterless printing.
