Selecting a paper collator depends heavily on your production volume and paper types. For small print shops, a friction-feed tabletop model is cost-effective for standard offset paper. However, for high-volume commercial printing or digital shops using coated/glossy paper, a suction-feed (air-suction) system is essential to prevent double-feeding and static issues. Ensure the machine supports the maximum and minimum paper sizes you handle, typically ranging from A5 to A3+, and check the bin capacity (number of stations) to match your most frequent page counts.
