The specification does not list file formats or OS compatibility. Typically such UV flatbed printers work with standard RIP software that accepts TIFF, JPEG, PNG, PDF and works on Windows. Confirm compatible file types and OS support with the vendor before purchase.

The printer uses a CISS ink supply; it is designed for UV-curable inks (including color and varnish). Always use inks recommended by Huacai to ensure adhesion, curing quality and warranty compliance.

Regular maintenance typically includes printhead/nozzle cleaning, periodic UV lamp checks, CISS tubing inspection, and wiping/cleaning the flatbed and bottle chuck. Follow the manufacturer maintenance schedule and use approved cleaning solutions to avoid damage.

UV printing emits ozone and VOCs from uncured inks; operate in a well-ventilated area and follow local safety regulations. Use appropriate PPE when handling inks and replace UV lamps according to manufacturer schedule. Confirm recommended ventilation and safety procedures in the manual.

Warranty terms, spare-part availability and technical support vary by vendor and region. Ask the seller for warranty duration, included consumables, availability of replacement lamps/heads, and options for on-site or remote technical support before purchasing.
