Offset lithography transfers an inked image from a plate to a blanket and then to the sheet. Digital printing images directly from data, normally with toner or inkjet. Both can produce excellent commercial work, but their cost and control profiles differ.
Setup and run length
Offset requires plates, ink-water balance and make-ready sheets before stable production. Once running, it can deliver high speed and a low unit cost across longer runs. Digital equipment has less physical setup, making short runs, repeat batches and rapid changes practical.
Digital also enables personalised text, codes and imagery because every sheet can be different. Offset is strongest when a long run uses a stable image and the job benefits from its format, substrate range or special ink capabilities.
Choose from the job backwards
Do not choose only from a run-length rule. Consider finished size, imposition, colour tolerance, paper, coverage, drying time, finishing and delivery schedule. Ask both suppliers for a representative proof and a total finished cost. A hybrid campaign may use offset for the main quantity and digital for regional, personalised or replenishment versions while maintaining a shared colour target.
