Selecting a stone printing machine requires matching the technology to your specific substrate. For natural stone like marble or granite, a UV Flatbed Printer is essential as it uses ultraviolet light to instantly cure ink, ensuring strong adhesion and scratch resistance. For high-volume industrial production, prioritize machines equipped with industrial-grade printheads (such as Ricoh G5/G6 or Konica), which offer a longer lifespan and higher firing frequency compared to desktop-grade heads. Ensure the machine supports a high printing thickness (at least 100mm-150mm) to accommodate thick stone slabs or tombstone blocks.
