When assessing the price of a rotary printing machine, you must look beyond the sticker price and evaluate printing speed (m/min), number of color stations, and effective printing width. High-end models typically feature independent servo motor drives for each color station to ensure high-precision registration (±0.1mm). Additionally, check the drying system efficiency (steam, oil, or gas) and the automatic blanket washing system, as these features significantly impact both the initial investment and long-term operational costs.
