Gongzheng GZH52KM PRO

Gongzheng PrimeJet GZH52KM PRO – 5.2m Roll-to-Roll UV Printer

The PrimeJet GZH52KM PRO is a super-wide roll-to-roll UV printer for print service providers producing outdoor advertising, retail graphics and illuminated displays at scale. It prints up to 5200mm wide on media up to 5mm thick. It handles billboard banners, frontlit and backlit materials, soft film, vinyl and wallpaper, and the UV-cured ink is dry the moment it leaves the printer.

High-volume output with fine detail

The printer takes up to 40 Konica Minolta KM1024 greyscale heads across 6 rows. You can choose 13pl KM1024i heads for speed or 6pl KM1024a heads for finer detail. A 6-row setup reaches 208m²/h in production mode and 166m²/h in quality mode, so large billboard jobs run through quickly. Light cyan and light magenta options give smoother gradients and more natural skin tones for close-viewing work such as light boxes.

Flexible head configurations

The printer can be built around the work you do:

• CMYK, or CMYK plus light cyan and light magenta, in 4 or 6 sets
• Fluorescent magenta and yellow for vivid, eye-catching colour
• White plus CMYK for backlit, window and clear-film applications

Multi-layer printing for illuminated displays

With white ink installed, the printer handles multi-layer work in one pass:

• 2 layers (W+C / C+W)
• 3 layers (C+W+C) for double-sided window graphics
• 4 layers (C+K+W+C) for day-and-night backlit signage
• 5 layers (C+W+K+W+C) for top-end illuminated displays

Precise media handling

• Heavy-duty rubber roller system: four rubber rollers at the front and rear of the printer keep media flat and accurately fed at high speed
• Air shaft feeding unit with dual holding rollers for secure, even tension across the full 5.2m width
• Triple roll feeding system lets you load and switch between multiple rolls
• Mesh printing kit for printing on mesh banner without ink passing through
• Auto height detector sets the head height for each material

Speed, precision and reliability

• Magnetic linear motor and metal encoder: fast, low-noise, precise carriage movement that stays accurate over long production runs
• Negative pressure ink supply with 5000ml tanks for stable delivery during long runs
• White ink recirculation and stirring stops pigment from settling and blocking the heads
• One-button positive purging makes head maintenance quick and simple
• Dual water-cooled LED UV curing gives consistent, low-heat curing on sensitive media

Operator safety built in

Built-in light curtains detect any foreign object in the print area and stop the printer automatically. Once the area is clear, the interrupted job carries on from where it stopped, so the print isn’t wasted.

Greener printing

Gongzheng’s technology carries UL GREENGUARD Gold certification for low chemical emissions. This suits interior décor, retail and public-space graphics.
