How do offset lithography and digital printing differ in setup and cost?

• A. Offset uses digital files only.
• B. Digital printing requires plates and longer setup.
• C. It is necessary to have expensive prepress steps, including plates, making offset costly for short runs.
• D. Offset requires plates and longer setup, but has lower per-unit cost at high volumes; digital offers quick setup and is preferable for short runs.

Answer: (D)

In printing, setup costs and per‑unit costs drive when a method makes sense. Offset lithography relies on creating printing plates and a make-ready setup before any ink hits the sheet, so the upfront costs are higher and the process takes longer to get running. Once that setup is done, the cost to produce each additional copy drops significantly, which is why offset becomes very economical for large quantities. Digital printing skips the plate process entirely, so setup is quick and flexible, allowing fast turnarounds and the ability to run small quantities without the plate-making steps. That’s why digital is preferred for short runs, while offset shines on high-volume jobs. The best choice captures both ideas: offset needs plates and has longer setup but lower cost per unit at high volumes, and digital offers quick setup and is better for short runs.
