Technical development status of commercial narrow-width rotary lithographic printing presses

Bei Dagang, general manager of Beiren Fuji Printing Machinery Co., Ltd., narrow-width rotary printing equipment gradually formed a category of products, mainly due to the increasing variety of products and small-volume businesses in the printed product market, marked personalization characteristics, and the continuous increase of narrow-width printed materials, printing and postpress The integration of processing procedures, multi-color print, advanced and complex. Commercial narrow web presses cover a wide range of product types. From the printed matter category, it can be roughly divided into trademarks, labels, ticket forms, postal advertisements, cover advertisements, product advertisements, publications, manuals, packaging, printing, and so on. Differentiating from printing equipment, there are mainly rotary lithographic printing presses, rotary flexographic printing presses, rotary screen printing presses, and multi-function printing presses. At the DRUPA 2000 exhibition, narrow-web printing equipment manufacturers around the world introduced narrow-width rotary printing equipment. The technical level of these products has been greatly improved, and the scope of application has become more extensive. It has a high degree of automation and can be transformed. The printing cylinder and the post-press processing unit are suitable for the diversification of prints. At the same time, digital printing technology has begun to be applied to narrow web presses. Manufacturers focused on digital printing such as XEROX and XEIKON have also introduced a narrow-width digital rotary printing device using a narrow-width rotary press as a model platform. For a long period of time in the future, lithography will still occupy a larger proportion in all printing methods, and narrow-width rotary lithographic printing machines will increasingly play an important role due to their unique characteristics.
