Technical specifications of water-based digital inkjet printers

Resolution is a key parameter for water-based digital inkjet printers, indicating the level of output detail; it typically ranges from 300 dpi to 2,400 dpi or even higher. Higher resolution yields sharper image details and smoother edge transitions, making it ideal for high-quality image output and the reproduction of intricate patterns. In practical applications, resolution is often balanced against production speed and quality requirements.

Printing speed is another critical technical indicator, usually measured by output area or linear meters per hour. Speeds vary significantly between draft and high-precision modes, with industrial-grade equipment generally capable of outputs ranging from tens to hundreds of square meters per hour.

Increased speed typically relies on the number of printheads, jetting frequency, and the performance of the media transport or platform motion systems.

Water-based digital inkjet printers typically utilize piezoelectric printheads combined with a standard CMYK color set or an expanded gamut (incorporating light inks such as Lc and Lm) to enhance color gradation. Factors such as the number of nozzles, ink droplet size (generally 1.5–10 picoliters), and the stability of the ink circulation system directly impact print quality and equipment reliability.

Other important technical specifications include the range of compatible substrates, drying methods, and the parameters of the power supply and control systems. For instance, supported material widths range from tens of centimeters to several meters; drying systems may employ hot air, infrared, or UV-assisted methods (for hybrid models); and control systems determine data processing capabilities and continuous production stability. Collectively, these parameters define the equipment's overall suitability for industrial applications.
