The LQ-4C Series is a 4-color flexographic printing machine designed for roll-to-roll production on plastic film, paper, and non-woven substrates.
Available in three substrate widths — 600mm, 800mm, and 1000mm — the series expands on 2-color flexo capability by delivering full 4-color print jobs in a single pass, enabling richer brand graphics, multi-color logos, and process color printing on bags and flexible packaging.
All three models operate at 5–50 m/min with variable frequency speed regulation, allowing operators to match print speed to substrate type and ink drying requirements. The anilox roller ink metering system ensures consistent ink density across long production runs, critical for brand color compliance on retail packaging.
A meter counter with auto-stop on quantity or web break protects against material waste, while the integrated drying system with auto-shutdown on stop prevents substrate scorching during unplanned halts.
Across all three models, the 2.38mm plate specification and 200–1100mm print length range remain constant — substrate width is the sole differentiator, simplifying selection and allowing plate stock to be shared between machines.

The LQ-4C Series is compatible with PE film, PP film, kraft paper, roll paper, and non-woven fabric across all three models.
All three models operate at 5 to 50 m/min with variable frequency speed regulation, allowing speed adjustment based on substrate type and ink drying requirements.
The three models differ only in maximum substrate width: 600mm, 800mm, and 1000mm respectively. Speed, print length range, plate thickness, and all core features are identical — select based on the widest substrate or bag format your production requires.
All three models support a printing length range of 200mm to 1100mm, covering small food pouches through large retail shopping bags.
All models require a total mounted plate thickness of 2.38mm, including double-sided adhesive mounting tape. This is a standard commercial flexo specification compatible with most photopolymer plate suppliers.
Yes. The meter counter system triggers an automatic stop when a web break is detected or when the preset production quantity is reached, reducing material waste and unattended run risk.
The LQ-4C Series is positioned after blown film extrusion or non-woven roll production and before the bag making machine. The workflow is: film/non-woven production → 4-color flexo printing → bag making.
All three models accept web rolls up to φ450mm in diameter on both unwind and rewind stations.
