Optimising a production process inevitably involves the adoption of innovative technologies that allow manufacturers to respond to growing market demand for flexibility, sustainability and cost reduction. In the specific case of wood-based floor plank colouring, using a digital printing machine to apply ink offers significant advantages compared to the traditional analogue technique with roller machines. At present, the use of roller machines requires producers to keep extensive stocks of dyes in order to create the variety of shades needed to match the different wood substrates. This application method has significant inefficiencies, especially as regards little-used shades: while the latter represent only about 25% of the total, they still need to be kept in stock to ensure they’re readily available to the customer. Vice versa, the remaining 75% of shades consist of frequently-used colours in large quantities. Introducing digital printing would drastically reduce stocks of lesser-used dyes, streamlining warehouse efficiency and limiting the costs associated with low-demand products. Furthermore, the flexibility of digital technology would permit rapid adaptation to the customer's customisation needs, reducing set-up and dye changeover times. The transition from an analogue to a digital system also meets sustainability needs as it reduces waste and optimises the use of resources. Investing in a digital printing machine would, therefore, not only improve the company's market competitiveness: it would also provide a practical response to warehouse management problems, enhance sustainability and speed up adaptation to demand. Such a change would bring tangible benefits in both economic and operational terms, favouring cleaner production in alignment with Industry 4.0/5.0 principles.
