RISO printing is remarkably cost-effective for high-volume jobs, making it one of the most economical methods for producing large runs of zines, flyers, and art prints. While the initial equipment investment and specialized color drums require capital, the per-page running cost drops to mere fractions of a cent once production begins, because master stencils and soy-based inks are exceptionally inexpensive when amortized across hundreds or thousands of copies.
