The Rongta F81S is a thermal tattoo stencil printer for turning digital artwork into monochrome outlines on compatible four-layer tattoo stencil paper. It prints at 203 DPI with an effective print width up to 208 mm, giving tattoo artists a compact way to prepare stencil designs without ink cartridges or toner. For a mobile workflow, pair a compatible iOS or Android device with the printer over Bluetooth and use Tattoo Flow to select and send a design. For a desktop workflow, connect a compatible Windows, macOS, Chrome OS or Linux computer by USB. The built-in display shows connection, battery and printer status, and paper-out detection helps you identify when paper needs attention. A rechargeable 7.4V 2400mAh battery and Type-C charging make it easier to move the printer between workspaces. Use compatible four-layer tattoo stencil paper measuring 0.15–0.20 mm thick.
