The offset printing business has been the cornerstone business of Komori since its founding. Offset printing is still the mainstream lithographic printing method for producing a wide variety of commercial and packaging products. It involves the transfer of ink from a printing plate to a rubber blanket, and then onto the paper. This process creates high-quality, consistent and sharp images, making it suitable for a many well-known printed products such as books, catalogs, posters and flyers.

Digital printing machines produce work without using traditional lithographic print materials or making a plate, reducing initial job costs. They achieve high quality from the first sheet reducing substrate waste significantly. These machines are characterized by an ability to produce consistent, high-quality print using a lower operator skillset, making it less labor dependent and more valuable in tight labor conditions. Moreover, they are able to print variable data for each impression creating high value-added printing. While offset printing remains essential for specific applications, digital printing has expanded the possibilities for meeting the evolving demands of the printing industry.
