What Makes a Quality UV Flatbed Printer? Key Components You Should Check

UV printers rely on several key components to achieve high-quality and high-speed printing capabilities. Understanding these core components provides insight into how UV printers operate and what factors influence their performance.

The print heads are the most critical component of any UV printer. They are responsible for actually depositing the UV ink onto the substrate. Print heads contain hundreds of tiny nozzles that jet out tiny ink droplets at very high speeds and with precise accuracy. The resolution, jetting frequency, and reliability of the print heads directly impact the printer’s imaging quality and production output. Advanced print heads using piezoelectric technology provide superior jetting capabilities. Rainbow Printers support both Epson print heads and Ricoh print heads which both have reliable options.

Servo Motors

Servo motors control the movement of the print heads along the X and Y axes when printing. They ensure the print heads move with optimal acceleration, precision, and repeatability during each pass across the substrate. The servo motors must be properly tuned to avoid irregularities in the print. High-performance servo systems allow for faster printing with fewer artifacts.

Vacuum Suction Table

The vacuum platen securely holds the substrate in place during printing using suction pressure. This prevents the material from shifting or lifting, which would disrupt the jetting from the print heads. Vacuum platens provide a perfectly flat surface and often include a grid pattern to optimize the distribution of the suction. This allows even delicate or warped materials to be held flat during the printing process. Rainbow UV flatbed printers offer a vacuum suction table option for all models.

Guide Rails

The guide rails and beams provide a smooth, stable movement path for the print head carriage. Any vibration or instability in the carriage would transfer to the print heads and degrade print quality. Precision linear guide rails maintain tight tolerances and dampen vibrations. They ensure consistent, smooth motion of the print heads across the material. In some models in the Rainbow Inkjet catalog, double linear guide rails are commonly used to maximize the print quality.

Steel Chassis

The printer chassis provides a strong, rigid framework to support all the printing components. The stability and durability of the chassis are critical for the mechanical accuracy and consistency of the printer over time. A solid welded steel frame resists deformation that could throw off print head positioning. The chassis must also absorb vibrations that occur during printing.
