What are the advantages, disadvantages and differences between UV ink and conventional ink?
Advantages: UV ink benefits from a nearly 100% curing system and instant curing. Key strengths include higher production efficiency, no powder spraying, and low VOCs. Additional benefits: abrasion resistance, solvent resistance, high trapping rate, low dot gain, etc.
Composition:UV ink: polyester acrylic resin, acrylate monomer, photoinitiator, inhibitor, filler, pigment, additives.Conventional offset ink: modified rosin resin, vegetable oil, mineral oil, pigment, antioxidant, desiccant, additives.
Curing mechanism:UV: irradiation → initiator activation → cross‑linking of double bonds.Conventional oil‑based: solvent penetration into paper → solvent evaporation → resin oxidation film formation.
Difference: Conventional offset ink has excellent flow and stable body; viscosity changes moderately with roller temperature during printing. UV ink shows more significant viscosity change, leading to larger differences in water‑ink balance and emulsification.
-
Is the lightfastness rating of UV ink the same as conventional ink?
Lightfastness depends mostly on pigments; resins differ only in yellowing tendency.
The main difference is in yellow ink: UV yellow can reach L5, conventional yellow only L3+. With identical pigments, lightfastness is similar. UV ink also has better water resistance after curing and slightly higher lightfastness due to photosensitizers.
-
How is the lightfastness of UV fluorescent ink graded? Why is it not lightfast?
Fluorescent ink is generally rated L1–3. Fluorescence relies on UV absorption and electron transition, making fluorescent pigments unstable. Under intense UV exposure, excited pigments cannot fully recover and decompose. Fluorescent pigments also have poor heat resistance (decomposition <120°C), while standard pigments resist >150°C and lightfast inks >180°C. Inorganic pigments (carbon black, white) have the highest lightfastness; resin yellowing must also be considered.
-
What information is needed to confirm lightfastness requirements?
Substrate material;
Process: coating or lamination;
Application conditions and lightfastness specification;
Color system and concentration; color swatch preferred.
For outdoor labels requiring ≥1–2 years of fade resistance: use top‑grade UV 161 SR series for red/yellow. For <1 year with red/yellow ≥50%: consider UV 161 Super Lightfast series. -
Why does UV printing look darker than conventional printing? How to improve?
Main cause: poor ink transfer. Insufficient leveling time also reduces gloss and makes colors appear darker.
Improvements:
Use UV HY‑BD series (slower cure, non‑skinning rollers) for better transfer and gloss; note slightly higher dot gain than 161 series.
Use dedicated UV presses/consumables; increase distance from ink unit to UV lamp, apply air pressure or coating to boost gloss. -
Why does UV ink often print unevenly? How to fix?
Improve wetting between ink and rollers, and enhance transfer. Ensure proper rollers and blankets are fully wetted. Use softer ink series: UV HY‑BD for packaging, UV GP‑LED for commercial printing. -
What compatibility limits apply to UV metallic ink with post‑processing?
Gold/silver ink must float to the surface for metallic effect, causing silver/copper bloom, poor abrasion resistance, and scuffing. Not suitable for coding, lamination, etc.; coating significantly reduces metallic gloss. -
If a printer has no curing equipment for UV ink matching and cannot accurately predict color for customers, how do you confirm ink color?
We confirm hue after full curing. Most colors change little after curing; exceptions: magenta, golden red, reflex blue, special black (surface‑change shades). For 161 series, we provide a formula sheet with over 1,700 HHC spot colors.

What are the risks of harmful residue, penetration, and migration of UV ink for direct/indirect food packaging (without aluminum foil)? Recommendations?
National food‑contact regulations mandate compliance with GB 9685; non‑compliant ingredients are prohibited for direct food contact. UV ink must print on the outer surface of a barrier layer.
Food‑packaging ink standards are under development; UV ink restrictions cover certain monomers, initiators, phthalates, referencing EU, US, and Nestlé standards.
Printing on non‑barrier materials violates food‑contact rules. Packaging interiors require barriers (aluminum foil, plastic film). With a barrier, strictly control back‑adhesion and rub‑off; pass migration testing: specific migration <10 ppb, total migration <10 mg/dm².
Without a barrier, use approved raw materials per customer requirements and provide a guarantee letter; the printer assumes liability.
-
What is food‑grade UV ink? Requirements and testing methods?
True food‑grade ink is ingestible (e.g., for pills, candy, cakes).
For packaging, food‑grade UV ink is low‑migration ink that meets regulatory compositions, uses a barrier layer, and passes GB 4806.X and migration tests.
-
Under the same UV curing conditions, why does black (K) ink cure slower/less completely than other colors? Causes and solutions.
Black ink strongly absorbs UV; thick layers block UV penetration to the bottom.
Solutions:
Use faster‑curing, higher‑concentration special black ink;
Combine LED‑UV (strong penetration) and conventional UV (excellent surface cure). -
Why can’t UV ink use alcohol‑free fountain solution?
Not absolute; suitable alcohol‑free fountain solution can improve UV printing. Offset depends on water‑ink balance and proper emulsification for stability.
Without IPA, UV ink is hard at start-up with low emulsification; alcohol‑free solution worsens plate fouling, prompting operators to increase water flow. As temperature rises, UV ink viscosity drops, body softens, emulsification rises, causing scumming and over‑emulsification.
Proper IPA (≈5%) enables fast initial emulsification and stable water‑ink balance. Adjust per fountain solution: pH ≈5, conductivity 800–1500. -
Why is LED‑UV more environmentally friendly?
LED‑UV emits narrow‑band UV (mainly 365–395 nm; we recommend 385 nm high‑power) with ~50% electrical efficiency. This far‑UV is harmless to humans/organisms (only tans skin) and no ozone (ozone forms near 250 nm). Conventional mercury lamps produce intense deep UV (<300 nm), heavy ozone, and high toxicity.Mercury lamp UV efficiency <20%, lifespan 1/10 of LED‑UV. Mercury is a toxic heavy metal; global mercury bans are expected by 2022, making LED‑UV inevitable.
Key benefits:
Ozone‑free, low heat, better workshop environment;
Long lifespan, low maintenance;
Low power (20%–50% of mercury lamps);
Zone lighting for paper size saves energy;
Modular replacement extends life and cuts cost.
