The technical specifications of UV printers primarily serve to gauge the equipment's printing precision, speed, stability, and scope of application; significant differences exist between models of varying tiers.
Printing precision and resolution are among the most critical parameters, typically measured in DPI (dots per inch). Standard equipment generally offers resolutions ranging from 720×1200 DPI to 2880×1440 DPI; while higher resolution yields sharper image detail, it often results in slower printing speeds. Additionally, minimum ink droplet size (e.g., 3.5pl, 5pl, 7pl) is a key indicator, as smaller droplets produce finer, more detailed imagery.
Printing speed and print area. Printing speed is usually measured in square meters per hour (m²/h), ranging from a few m²/h for entry-level models to tens of m²/h for industrial-grade machines. Print area varies by model-common sizes include A3, 6090 (60×90 cm), and 1610 (160×100 cm), alongside larger industrial flatbeds designed to meet production needs for products of various dimensions.
Other parameters include printhead configuration, color channels, and the curing system. The number and type of printheads (e.g., Epson, Ricoh) directly impact productivity and stability. Color channels typically consist of CMYK + W (white ink) + V (varnish), with some models supporting additional extended colors. Curing systems fall into two categories-LED UV lamps and mercury lamps-with LED UV systems offering superior energy efficiency and longer service life. Furthermore, factors such as repeatability (positioning accuracy), RIP software compatibility, and the platform's media holding method (e.g., vacuum suction) serve as important technical benchmarks for evaluating overall machine performance.
