DUSSELDORF, GERMANY—  Drupa Essentials of Print Article No. 21.To illustrate an industry transformation, the book printing industry could be a prime example. The process of producing them has completely changed and will continue to evolve, primarily driven by a complete digital journey. One of the significant changes we have witnessed in recent years is related to the demand for books. According to several statistics, sales volumes are increasing both in Europe and the U.S. However, traditional bookstores and supermarkets are losing market share, as online and direct sales channels are increasingly preferred by customers, representing more than 45% of total revenue for publishers. The influence of "BookTok" trends has propelled certain books from relative obscurity to bestseller lists, leading publishers to reconsider their marketing strategies, especially for niche books. To manage such demand effectively, accurate forecasting has become crucial. Publishers need to serve the market on time while avoiding excessive printing that surpasses demand. As a result, a few book printers are seeking new value propositions and services, focusing on on-demand production of individual books, short Service Level Agreements (SLAs) from order to shipping, and digital integration with publishers and distributors. These companies are investing not only in digital equipment but also in software business platforms, firmly believing that robust automation is the key to competitiveness and profitability
