Label printing challenges? Engineered for durability & speed
Poor Adhesion on Difficult Films
Labels peeling or ink flaking on untreated PP, PE, or high-slip materials.
Chemical & Solvent Exposure
Industrial containers fading or smearing after contact with alcohol, oils, or cleaning agents.
High-Speed Press & Instant Curing
Slow drying causes smearing or set-off on high-output label presses.

β Label durability standards & testing
StarColor label inks are rigorously tested to meet global performance requirements for end-use applications: from food contact regulations to industrial chemical resistance and outdoor weathering.
Reliability guaranteed: Our UV-LAB and WB-LAB series withstand 100+ rub cycles (Sutherland Rub test), 24h exposure to isopropyl alcohol, and UV resistance up to 500h QUV.
π Representative test reports for label printers:
- Water immersion test: 72 hours β no blistering, no adhesion loss (UV Flexo UV7000 series)
- High-temperature resistance: 200Β°C for 48 hours β no discoloration, no cracking
- Low-temperature resistance: -20Β°C for 48 hours β excellent flexibility, no embrittlement
*Full reports and customized recommendations available for your label construction.
π Success Story: Premium Wine & Spirits Label Converter
The Challenge
A premium label converter faced 8-10% field returns on wine and spirits labels due to scratches, ink rub-off, and chemical damage from ice bucket immersion, condensation, and handling friction. Multiple ink suppliers had failed to solve the problem, and the brand owner was considering switching to a competitor.
The Diagnosis
StarColor's technical audit identified three root causes:
β Under-cured UV ink β low crosslink density, soft film
β‘ Inadequate OPV β generic varnish failed under moisture exposure
β’ No primer β metallic foil substrate lacked adhesion layer
The Solution
StarColor developed a complete system:
β UV-AR Series ink β high-crosslink-density formulation (2H pencil hardness)
β‘ OPV-G-HR overprint varnish β chemically resistant, high-gloss protection
β’ UV-PR primer β adhesion promoter for metallic foil
β£ Optimized UV curing β adjusted photoinitiator package and lamp intensity for complete crosslinking
The Results
| Metric | Before | After |
|---|---|---|
| Field return rate | 8-10% | <0.8% |
| Sutherland rub test | 50 cycles | 300+ cycles |
| Pencil hardness | HB | 2H |
| Ice-water + condensation test | Fail | Pass |
| Gloss retention | 75% | 95% |
Business Impact:
β
Annual savings: $50,000+ from reduced reprints and returns
β
Brand owner renewed contract for 3 additional years
β
Converter won 2 new premium spirits accounts
"StarColor partnered with us to solve a complex problem. Their solution is now our standard for all premium labels."

Frequently asked questions β Label printing
β Do your UV flexo inks work on untreated polypropylene?
While flame/corona treatment is recommended for optimal adhesion, our UV-LAB primerless series significantly improves wetting on difficult low-surface-energy films. Contact us for substrate-specific trials.
β Can your inks be used for outdoor labels (e.g., chemical drums, garden products)?
Yes, our UV weather-resistant line offers excellent UV stability, water resistance, and chemical durability for 2+ years outdoor use. Ask for our QUV accelerated aging data.
β What's the difference between water-based and UV label inks?
Water-based: lower cost, ideal for paper labels and uncoated stocks. UV: instant cure, higher chemical resistance, best for films/shrink sleeves and high-speed converting. We offer both with dedicated formulation support.
β Can you match custom brand colors for label printing?
A: Yes. Our in-house color lab provides Pantone-matched formulations and can work from your physical label samples. We maintain strict batch-to-batch Delta E control to ensure your brand colors remain consistent across every production run and reorder.
