When sourcing these machines, prioritize positioning accuracy (±0.05mm or better) and software compatibility with mainstream design tools like Adobe Illustrator or AutoCAD. For laser-based gift machines, ensure the laser tube power (e.g., 40W-100W) matches the materials you intend to personalize, such as wood, acrylic, or leather. For UV printing gift machines, verify the print head type (e.g., Epson i3200) and the presence of a white ink circulation system to prevent clogging during idle periods.
