Inside the plant — from raw material to finished batch
An expansive view across HCOLOR's 30,000-ton eco-friendly ink production facilities and automated manufacturing floor
Explore our integrated 30,000-ton smart manufacturing facility, cleanroom synthesis workshops, and high-precision testing laboratories below.
R&D Center — Precision X-Rite benchtop spectrophotometer color matching (ΔE < 0.5)
01 / 03
At HCOLOR's Dongguan R&D Headquarters, our engineers formulate customized eco-friendly printing inks, synthesize high-performance water-based resins, and establish digital color standards. Equipped with benchtop X-Rite spectrophotometers and pilot gravure proofing presses, we deliver precise color consistency (ΔE < 0.5) and press-ready formulations for global packaging converters.
Water-based Line — Battery of heavy-duty horizontal nano bead mills (<2μm fineness)
01 / 03
Our flagship water-based ink production lines utilize closed-loop nano bead mills and automated pneumatic dispersion systems to mill pigments below 2 microns. Engineered for high-speed gravure and flexographic presses, these food-safe, low-VOC inks provide exceptional transfer and gloss for tobacco cartons, aseptic beverage packaging, and PVC furniture edge-banding across our 30,000-ton annual capacity network.
UV Line — Climate-controlled cleanroom illuminated by anti-UV yellow filtration lighting (>500nm)
01 / 03
Operating inside an isolated yellow-filtered cleanroom to prevent premature polymerization, our UV and LED curing line manufactures high-speed offset inks, screen inks, and tactile surface varnishes (reverse matte, gloss, and sand textures). Precision three-roll mills eliminate micro-bubbles, ensuring instant radiation curing, superior scratch resistance, and long-term shelf stability in light-barrier packaging.
Solvent Line — Class-1 Division-1 explosion-proof workshop with RTO VOC recovery
01 / 03
Constructed to international Class-1 Division-1 explosion-proof standards, this dedicated line features high-shear hydraulic dispersers, nitrogen-inerted mills, and negative-pressure regenerative thermal oxidizer (RTO) VOC recovery systems. Formulated for BOPP, PET, CPP, and aluminum foil packaging, our solvent inks provide robust lamination bond strength and chemical durability with automated static-grounding safety.
QC Lab — Standard D50/D65 light booth visual comparison and spectrophotometer verification (ΔE < 0.5)
01 / 03
Every batch is rigorously tested against reference standards before release. In our certified inspection lab, quality engineers verify spectral color tolerance (ΔE < 0.5) in standard D50/D65 light booths, measure viscosity with Brookfield rotational rheometers, and conduct Hegman grind and Sutherland rub-resistance tests. Gas chromatography-mass spectrometry (GC-MS) guarantees full compliance with global RoHS and low-VOC regulations.
Warehouse — Climate-controlled 8-tier high-bay racking for raw resins and organic pigments
01 / 03
Featuring climate-controlled high-bay racking and intelligent Warehouse Management Systems (WMS), our storage and logistics center maintains end-to-end batch traceability from raw pigments to finished containers. Automated turntable stretch-wrapping and barcode serialization ensure moisture-proof, secure palletization for containerized sea freight and rapid road dispatch from our Dongguan, Kunming, and Yueyang production hubs.
