An A3 machine earns its place when you are laminating posters, plans, seating charts or display work that would otherwise have to be trimmed and taped together. The trade-off is footprint and warm-up time, both of which are longer than A4. If most of your work is certificates and labels with the occasional poster, an A4 unit plus outsourcing the large jobs is often cheaper. Match the A3 pouch micron to the machine, and see all laminators to compare.
