Flexographic Printing Machine with Uv Drying
UV flexo lines for labels and films require inter-station curing matched to ink viscosity and line speed. This page links UV-capable CI and stack presses with anilox and lamp configuration guidance.

Principle, machine fit, and parameters
How it works
UV lamps cure ink by photoinitiator dose (mJ/cm²), not by “drying heat” alone. Inter-station lamps must match ink viscosity, opacity, and line speed. A press can mechanically run faster than the lamps can fully cure opaque white.
Machine fit
Honor and label-oriented CI/stack builds often carry UV between stations. Wide-web Master/King food-film lines more often use hot-air or hybrid drying unless the buyer specifies UV coatings or specialty labels.
Parameter range
Quote lamp type (LED vs mercury), peak irradiance, and dose at your target speed. Opaque white and dense blacks usually need more dose than process CMYK. Interdeck UV between stations is specified separately from end-of-press curing.
Common faults
Tacky ink, odor, and set-off after rewind usually mean under-cure. Over-cure can embrittle film and raise web temperature. Dirty quartz and aging bulbs drop dose while the HMI still shows “UV on”.
Options & add-ons
LED UV for lower heat on thin film, nitrogen-inerted UV for some high-gloss coatings, and chilled rollers after cure. Confirm ink supplier windows before locking the lamp package.
Plant example
A shrink-sleeve plant often hits a wall at opaque white until interdeck LED dose is raised—even when the CI frame could run another 50 m/min mechanically.

Master Series
Based on your profile: labels, sleeves, and some film jobs · UV flexo inks and coatings · 600–1100mm typical · limited by lamp dose, not only drive
Master Series is the strongest fit for labels, sleeves, and some film jobs because Best fit when converters need a reliable CI platform for mixed film, paper, non-woven, and FFS jobs without the highest investment. At your target speed of limited by lamp dose, not only drive, this platform keeps register stable, startup waste low, and changeovers practical for repeat jobs.
You selected UV flexo inks and coatings. Master Series is engineered for film, paper, non-woven fabric, ffs heavy-duty sack. Core substrate window: film, paper, non-woven fabric, ffs heavy-duty sack. This reduces tension surprises and ink-transfer issues on your primary material.
Width target 600–1100mm typical and speed limited by lamp dose, not only drive sit inside the Master Series envelope (1000-1600mm, 500m/min). Budget Mid to high range and High automation align with high-automation workflows at this output level.
Key advantages: Balanced CI stability; fast job changeover; wide substrate window. Tradeoff to confirm: Less suitable than King for ultra-high-speed thin-film repeat jobs. If your mix shifts toward ultra-thin film at 400–500 m/min, compare with another LISHG line before finalizing.
Uv Drying FAQs
LED UV or mercury lamps for flexo labels?
LED cuts heat and warm-up on thin film and many label stocks; mercury remains common where ink houses still certify only mercury dose curves. Confirm with your ink supplier.
Can every CI film press take full UV?
Not by default. Wide-web food-film CI often stays on thermal drying; UV is an engineered option for coatings, sleeves, or label hybrids.
